Today we look at ASUS’ top of the line AMD board, the Crosshair V Formula. The Formula houses AMD’s newest chipset, the 990FX northbridge and SB950 southbridge.
Packaging and First Look
ASUS doesn’t fix what isn’t broken and they’ve presented their Crosshair V Formula as they did the Crosshair IV series before it. There is a flap covering a window that allows you to peer into the board without even opening up the box. There are detailed specifications as well as feature highlights all over.
You didn’t come here to see the box though; let’s pull the board out and have a look at it from plenty of angles.
First impression: this is one really good looking board. I like the IV Formula, but the V is in a class by itself. Top to bottom this is one of the best looking motherboards out there. I don’t even really like the red/black RoG theme, but what they did with it here is second to none.

Whew, that is one looooooong list. Can’t really knock them though; the board does have a ton of features and you can’t blame them for wanting to show them off.
The accessories bundle is full of connectivity. There are six SATA 6 GB/s cables, two- and three- way SLI bridges, a crossfire bridge and the ROG Connect USB cable. In addition, you get a quick start guide, manual, driver disc, rear I/O plate, easy-connectors for front-panel connections and that gawdy, horrible RoG stocker they insist on sending with their boards.
It’s a strong accessory package, but words can’t do justice to how awful that sticker is. Who uses those things? They can do better than that. It doesn’t look bad on the manual, but when translated to sticker form it just looks….bad.
Up Close and Personal
Moving the camera a bit closer to the board, let’s have a look at some of its features, a lot of which are contained in this very first photo. Most conspicuous is the expansion card area. There is are one each of PCI and PCIe x1 slots. To compliment that, there are four PCIe x16 slots. Not all of these operate at 16x though. The top slot is, of course, 16x. The bottom one is dedicated at 4x.
The two middle x16 slots operate at 8x or 16x, depending on the configuration. If you run two-card SLI/Crossfire, ASUS recommends using the first and third slots; both cards will operate at 16x. If you run tri-SLI or tri-Fire, use all three (but not the one that operates at 4x). Tri-SLI/tri-Fire configurations will operate at 16x on the top card and 8x on the bottom two.
To the lower left, you see the SupremeFX X-Fi2 sticker residing over the sound chip. At the bottom is the on-board power and reset switches -very important to overclockers- as well as the CPU Level Up button.
Moving to the upper right section of the board, we see the four DIMM slots. If you’re using an x6 (or greater, when FX arrives) CPU, ASUS recommends using the two red slots first to get the best performance. After some testing though I found the gray slots to be equal or ever so slightly faster. They may be referring only to FX, only time will tell. You can see just below the RAM slots in this picture the two alloy chokes and MOSFETs that make up the board’s two-phase dedicated RAM power.
At the bottom of this photo (it’s hard to see) below the power connector are the Q_LED indcators. These have grown on me since first seeing them on the Crosshair IV Formula and then the IV Extreme. Earlier, I was partial to a POST code indicator, but the more I saw these in action, they seem more and more practical. For people that aren’t uber-geeks that have memorized the POST codes, these are a quick and easy way to know where the system is failing at boot. Thus, consider earlier criticism of the lack of a POST code incdicator retracted. This solution is better for 99.9% of users, from extreme overclockers to gaming enthusiasts and in between.
On the far right at the top is an extra 4-pin CPU power connector to bolster the CPU power section when overclocking at high voltages. Below that is the first of two CPU 4-pin fan headers. Across the adjacent capacitor is the second CPU fan header. These are positioned close to each other and can easily be used to power push-pull fans on an air cooler.
Coming a little closer to the far upper right side of the board, we see several more overclocker-friendly features. You can see a little better the 2nd CPU fan header (CPU_OPT) and even a third fan header positioned on the far upper right of the board. It’s actually hard to get a photo without a fan header on this board, considering that there are eight of them.
At the top of this photo, those silver contacts are the ProbeIt voltage read points for you to use a multimeter for accurate, real-time voltage monitoring. Most ‘regular’ users won’t use this feature, but they are very important for extreme overclockers. My only wish is that they had easy multimeter probe connections like the Crosshair IV Extreme. That can be solved by soldering wires onto these, but it’s easier to plug in a connector that easily fits multimeter probes.
Lastly in this photo is the GO button, which also serves as the MemOK! button. When used as the GO button, press this and it automatically applies the profile you save for the GO button in the UEFI. Even more practical for overclockers that love to push their memory hard is the MemOK! function. When the system fails to boot due to memory settings (overclocked too far, timings too tight or voltage too low for instance), hold this down for two seconds and the UEFI will automatically drop the memory speed and/or loosen the timings until the board can boot. This is invaluable to save yourself from having to clear CMOS and obliterating all of your settings just because you pushed the memory too far.
Here we have two of the important chips on the board. To the left is ASUS’ Digi+VRM/EPU controller that handles the advanced power management on this board. To the right is the Intel Ethernet controller.
ASUS considers the Intel controller to be a big deal, reducing CPU cycles you need to dedicate to your controller under heavy usage. Their GameFirst software even allows you to set the network priority of your game to help reduce lag.
Moving on to connectivity, the Crosshair V Formula has six SATA 6 GB/s ports (can we call that SATA III yet?) controlled by the SB950 southbridge. The seventh is controlled by a separate controller and isn’t side-facing like the rest of the ports. It’s nice to have the option to use a seventh port (for, say, an ODD), but to put it in that orientation just seems odd, like it was an afterthought. With the added controller, I’d like to have seen two new ports and have it in the same orientation as the rest of the ports.
The rear panel’s contents are described in the specification list above. Needless to say, just looking at it, you can see there is a plethora of connectivity available. The only thing that may give some enthusiasts pause is the lack of two ethernet ports. I applaud them for not including it though and have always thought it extraneous and unnecessary for the vast majority of people. It seemed like a lot of manufacturers just did it on high end boards because they felt the need to throw the kitchen sink at them. This was a step in the right direction – focus more on the board and less on extraneous options few, if any, use.
Of course, as important as anything else to overclockers is the rear clear CMOS button, which is present on this board as it was on the IV. Those are a godsend for overclockers; I wish every board had one.
Last, but not lest, we present socket AM3+, or as Foxconn labels it, socket AM3b. It has the same hold-down mechanism as its predecessor but the pin count has increased to 942 from 941.
Time to get down to the nitty gritty and pull those heatsinks off.
Under the Hood
There are two heatsinks on this board. One for the MOSFETs and northbridge combined and one for the southbridge. These aren’t connected like they are on some boards (Gigabyte’s 990FXA-UD7 comes to mind).
There are actually MOSFETs on the back of the board too. They are two slim pieces of metal that serve both to dissipate extra heat and as backplates for the main heatsink. The main assembly is quite stout and does a good job of keeping the board cool. The southbridge heatsink actually seems to be designed like a heatsink rather than the typical slab o’ metal. The branding doesn’t help much but the southbridge doesn’t get very hot anyway. All of the heatsinks had good contact throughout.
My only complaint, and it is consistent through every board from pretty much any manufacturer – the TIM is a massive pain to remove. You knew that already though, it’s nothing knew. Do I wish they’d stop that? For sure. Are they going to? Probably not – the stock stuff is sufficient for 99% of people. The few that will change it are those that just want to replace it to be doing so, those that want to use water blocks and those who want to take photos of the north- and southbridges (you know…us).
ASUS has outfitted the Crosshair V Formula with an 8+2 phase “EXTREME ENGINE DIGI+” digital power section. All of the inductors are ally chokes (better than ferrite used on other boards), the MOSFETS are low RDS(on) and the capacitors are FPCAP 5K Graded Premium Caps.
One question I had of ASUS was precisely why alloy chokes are better than ferrite chokes. Their answer was that they offer lower temperatures, increased frequency response and tend to last much longer than alternatives. That all, of course, depends on the quality of the alloy chokes employed and ASUS says theirs are at the top end of that spectrum.
To the average user, does this really mean much? Not really. Your board may last a little longer, but considering the audience interested in boards of this caliber it will be replaced long before one of these chokes fails, regardless of whether it’s ferrite or alloy. It’s still a nice thing to have and they do claim at the bleeding edge of your system’s capabilities when overclocking on extreme cooling these do offer some more stability, which is probably a reasonable assertion. Regardless, I’d rather have overkill components than ones not up to the task.
Last on our board tour are the 990FX northbridge and SB950 southbridge. The only change from the 890FX/SB850 is a model number. The silicone is the same. It has some different features from firmware/software implementation (the biggest being purported power saving features of the upcoming Bulldozer-based Zambezi CPUs), but for all intents and purposes not much has changed here.
Enough looking around, let’s turn the system on!
This UEFI is very similar to the one we saw on the P8P67 WS Revolution earlier this year, except for the AMD options of course. When you first enter the UEFI, you are put right in the Extreme Tweaker menu. From here you do pretty much anything associated with overclocking your system. There are bus clock, multiplier and voltage controls right there when you first enter the UEFI. This board is made for overclockers.
Voltage control is extensive and plentiful. There is a control for everything and then some. The settings in the photographs are what ran 4093 MHz 24/7 stable on this CPU.
I’ve said it before and I’ll say it again – ASUS loves their RAM tweakers. Every timing you can think of is in their RAM menu. Timings not enough? How about DRAM driving controls for even more flexibility? There is even a GPU.DIMM Post window to show you what GPU and, more importantly, what RAM you’re running, where it’s running and at what speed it’s running. ASUS hearts RAM nuts.
Next up, we have the Digi+VRM menu. I’m torn on Digi+VRM. For most people, especially those that value power saving and efficiency, Digi+VRM is wonderful. It offers granular control over many settings to get the most efficiency out of your system.
That said, for many overclockers, it would be easier to have just voltage and LLC. The rest can go for a lot of folks. Most want to set their Vcore, set LLC to where it needs to be and then overclock. With Digi+VRM, you absolutely must tweak it or you’re in for a rude awakening at high Vcore. As a person who loves to tinker, I enjoy the challenge and the extra functionality Digi+VRM offers, but it does take some getting used to and you should know that going in.
In the screenshot you can see the settings I used for this overclock (4093 MHz). As my concern is mostly for performance rather than efficiency, I went with ‘high’ or ‘extreme’ a lot. High LLC holds Vcore pretty much where you set it. Extreme overshoots set Vcore a little bit. I also bumped up the VRM frequency and voltage over-current protection.
The Advanced menu is where you’ll find your other CPU options like Cool n’ Quiet (CnQ) and where you can turn cores on and off at will. If you have a capable CPU, it’s also where you can attempt to unlock extra cores.
Another nice item in the UEFI is the strong fan control available to go with the many fan headers on the board. Not all of them can be controlled, but several can. The controls are extensive and flow perfectly between settings in the UEFI and with Fan Xpert, a program in AI Suite (see below). So I get this right, I’ll just quote ASUS – “Only the CPU and Chassis fan headers offer multiple control paths (three presets or manual with temp and/or cycle settings plus full customization of the ramp mapping under Fan Expert). The OPT fan headers offer either duty or temp settings.”
The other main menu we’ll look at in-depth is the Tool menu. This houses several of ASUS’ best UEFI features. The first is excellent for at-a-glance checking your RAM’s timings and sub-timings if you want to tweak them – ASUS SPD Information. More snuggling up to RAM tweakers, I love it!
Next up is the EZ Flash 2 Utility. It has received the GUI sprucing up of a UEFI interface, but it’s the same old EZ Flash 2 and there is absolutely no reason to change it. Its job is to flash your UEFI and it does a great job of it. Coming from someone who used to use DOS to flash many-a-beta-BIOS back in the day, this tool is a godsend.
It’s important to note that ASUS blocks flashing backwards to a prior UEFI if the new version contains updated AGESA code from AMD. So if there is a beta floating out there, make sure you can live with the consequences if you want to flash it. UEFIs without AGESA code updates will allow flashing to the previous version. In special cases their tech support has a tool you can use to flash back to a prior UEFI even with AGESA code update, but it’s not publicly available. This isn’t a change to their previous policy with BIOS flashes, it’s just a clarification for anyone that doesn’t know the policy.
Last, but not least is another godsend for overclockers – O.C. Profile. You can store eight total UEFI profiles here. As you can see, I have one ‘stock’ (with RAM dialed in and things like the extra storage controller turned off to save boot-up UEFI time), one 24/7 OC and the other a high overclock base level to start from. This is a great tool that keeps you from pulling your hair out after you clear CMOS when overclocking.
Finally, we have the remaining windows that house your other, more typical system settings. Every screen is photographed below for your perusal. They contain everything you need to dial the rest of your system in just the way you want it.
All in all a solid UEFI. It’s quick and responsive to input. You can navigate equally quickly with both mouse and keyboard. The features ASUS ads are superb all around. Certainly no complaints on the UEFI front.
To to with their UEFI, ASUS has also supplied AISuite. This is a departure from the earlier Crosshair IV Formula, which came with TurboV EVO in a standalone installer. To get AISuite on the AMD side with the previous generation, you had to go with the Crosshair IV Extreme.
I’m not sure if this means we won’t see a Crosshair V Extreme at this point.With this software suite and SLI native on AMD chipsets now, there isn’t much for it to add. The Lucid Hydra chip added SLI and the ability to use NVIDIA and AMD cards in conjunction with each other, but anyone that actually purchases a system with multiple cards (as opposed to using what you happen to have lying around) will get two identical cards so they’re not limited by their next motherboard. Other than the improved voltage read point interface of the IV Extreme, there isn’t much to differentiate the two that comes immediately to mind.
Anyway, sorry for the tangent. On to AISuite! First we’ll look at the main menu and the available sub-menus. The AISuite interface is quick and responsive. It doesn’t take very long to load on system boot-up either because it doesn’t load the individual programs until you actually select them. That said, I was using an SSD, so it may increase bootup time by just a little bit if you’re using a HDD.
First up in our screenshots is the most important for overclockers – TurboV EVO. It hasn’t changed much from the Crosshair IV other than to insert it into AISuite. You can control pretty much everything you can from the UEFI with the exception of RAM, HT and CPU-NB multipliers (which require a hard reset from UEFI and couldn’t be changed on the fly even if ASUS wanted to include that). The implementation of changed settings is fast and bug-free. There isn’t any reason to change anything here because it works so darn well to begin with.
Next up are two new features not present on the earlier Crosshair IV models – Digi+VRM and EPU control. The Digi+ VRM is especially impressive. Because of that little chip photographed earlier, you have complete in-OS control of the power section of motherboards with this feature. Before Digi+VRM, no one could change features such as LLC from inside the OS. This is the first implementation of the feature on an AMD-based ASUS board and it works just as well as its Intel-based predecessors. For power management on AMD, this is a leap forward.
EPU is not necessarily as mind-blowing but does bear mention that it too has complete OS functionality. Those of you that wish to save power (and thus money) will have that ability too.
Fan Xpert, Probe II, Sensor Recorder and the sensor readers are unchanged from previous AISuite implementations. They all work great, as they should, and do their job admirably.
AISuite has spoiled people that have it. It’s easy to take for granted something that does its job so well. ASRock’s software (which we explored in reviewing their P67 Extreme 6 earlier this year) just doesn’t compare. Gigabyte has EasyTune 6, which isn’t as seamless as AISuite in many respects. ASUS did right by overclockers, tweakers and just everyday users with this software and it continues to impress.
This board also comes with RoG Connect, which allows on-the-fly adjustment of pretty much everything other than multipliers via the included USB cable. It also offers monitoring capabilities.
This is a great tool for extreme overclockers on the edge of stability. They can, for instance, begin running 3DMark Vantage at on CPU overclock, then reduce the overclock for running the CPU tests with a quick bus clock adjustment. This allows for higher graphics scores (which don’t stress the CPU quite as much) while maintaining stability through the grueling CPU tests.
In this review, we’ll look at the Crosshair IV Formula and Crosshair V Formula head-to-head. Everything was as close as you could get it. Windows 7 had the standalone Service Pack 2 installed as well as any applicable updates. To keep it reasonable for what you can expect out of daily use, Avira antivirus and AISuite were installed as well (well, TurboV EVO on the IV).

This is a photo of the test set up. The Crosshair IV was tested under air in a case, but with Bulldozer coming I went with the benching station and water loop combo.
Let’s get to it!
Overclocking this board was a breeze. With the new UEFI I found it was even a little bit easier than with the previous BIOS, mainly because you can use the scroll wheel to go up and down in menus. A person could get used to that kind of pampering.
The 24/7 overclock reached for purposes of benching in this review was 240 x 17, or officially 4,080 MHz. It actually ran at 4,093 MHz due to a little bus clock overshoot of ~.8 MHz. This was a little higher than I could get previously with this CPU on air, at least while maintaining good temperatures (thanks to the water loop). No motherboard will make a CPU better, and this one overclocked similarly to the IV before it. No surprises, but certainly no disappointments.
One very important point to mention is that the Crosshair V does not suffer from bus clock fluctuation that plagued the Crosshair IV. After staring at CPUz for five minutes under load, I saw literally 0.0MHz bus speed deviation. HT freq deviated max 0.3MHz and CPU-NB freq deviated max 0.2MHz. I’d call that a vast improvement over the 890FX fluctuations of the past. Those fluctuations didn’t much affect most people other than to exist. However, those that pushed the Crosshair IV under extreme cooling at the bleeding edge of stability were hampered by their system crashing due to too much bus fluctuation.
I didn’t run any push-the-overclock benchmarks. You can read all of those in the 1100T review we wrote on its release. What I did do was see how far the CPU could go on a water loop. Turns out, at excessive voltages identical to the ones used on air last time, it managed 25 MHz more than previously. Whether that has to do with cooling or the motherboard isn’t something that can be determined for sure. The highest CPUz validation I could manage was 4575.6 MHz and did manage to actually validate through CPUz.
Overall a very similar overclocking experience to its predecessors, which is nothing less than expected. We’ll push this board hard and cold when Bulldozer shows up!
Now on to the benchmarking results. The tests were run three times each and the results you see are averaged. The only exceptions were PCMark 7 (which runs three iterations within itself and was run twice rather than three times), 3D benchmarks and overclocked benchmarks, which were run once each.
The results you see below are graphed relative to the Crosshair V Formula’s stock performance. This means that results by the Crosshair V at stock all equal 100% and the IV and overclocked results are graphed as a percentage relative to the V’s performance. So, for instance, if the Crosshair V scored 100 points on a benchmark and the Crosshair IV scored 95 points, on the graph the V would = 100% and the IV would = 95%.
CPU, FPU and Memory Performance
To start with, we’ll look at the one benchmark that was only run at stock speeds – AIDA 64. The first and second graphs on our plate are the AIDA 64 CPU and FPU tests, respectively.
Well then, as you might expect with the same CPU and RAM all set at the same speed, there was very little variation. Nothing meaningful can be gleaned from these results other than that the 890FX / 990FX difference really is only a model number. How about memory?
In the case of memory, there was at least one test with significant variation – the Memory Copy test. It seems when copying to and from memory, the Crosshair V Formula falls slightly behind the IV. No variation in all 13 AIDA 64 tests was greater than 4.2%, and that was only one result. Removing that one result, the greatest difference was 0.9%.
Rendering and Compression
Now some ‘real world’ results. We’ll use Cinebench R10 and R11.5 to test rendering performance and 7zip to test compression performance.
Cinebench R11.5 is a wash, with little noticeable difference. R10 is a different story, with the IV out-performing the V again by a noticeable (but still negligible) margin. The very-close-to-even scale tips back to the V when compressing and decompressing files.
3DMark06 and 3DMark Vantage are both pretty CPU bound at this point. These results are graphed with the subtests too so you can see where the differences lie.
The biggest difference there is one test in 3DMark06, which pulls down the overall score it would seem. In Vangage, the Cross V is consistently 0.5% better than the IV. Except for that one 06 anomaly the graphics tests were spot on with each other. The CPU tests were so close as to be indistinguishable.
3DMark 11 shows nearly identical graphics performance but falls slightly behind when the CPU is introduced to handle physics.
Now we’ll look at the ‘real world’ graphics tests. You may notice one of stalker’s sub-tests is missing. For some reason, throughout its life, the Cross IV bugged out on that one test and maxxed out FPS around 181 no matter what, thus it was eliminated.
It would seem the Crosshair IV has a slight, but noticeable advantage when it comes to graphics. That said, it’s only noticeable in graphs; is anyone going to notice three FPS when playing a game? I doubt it.
Now we see how the two boards compare on a full system test, inclusive of storage.
The overall system score was only 0.1% different. Storage went both ways but in two out of three tests the Crosshair V holds an advantage. The second graph above is a hodge podge of every other system test. What does it really tell us? That the two boards are virtually identical in performance, just like we’ve established pretty well already. I didn’t list the actual result numbers in that graph because they wouldn’t fit and I didn’t think you needed an extra graph just to fit that.
2D benchmarking performance will come to us courtesy of two benchmarker favorites – both iterations each of SuperPi and WPrime. Remember, unlike everything else above, in these graphs lower is better.
They are pretty even here too, but SuperPi 32M shows slightly stronger memory subsystem performance on the V, beating the IV’s time by only 0.8% – however, that 0.8% equals nine seconds, a substantial amount in the end, at least as far as SuperPi 32M goes. Wprime both go to the Crosshair V but, like everything else are very close.
Final Thoughts & Conclusion
The Crosshair V Formula is one stellar motherboard. There is nothing this board can’t do. Well, I’m sure there is but do you need it to?
The stout power section will help push your clocks to the max. The cooling solution does its job well. Performance is precisely on par with its predecessor as you’d expect from essentially the same chipset. It even looks good, in my opinion improving on the Crosshair IV’s looks greatly.
Now, please excuse a slight tangent. The only thing I would caution against is running out and replacing your 890FX motherboard quite yet, even if you’re planning on upgrading to a new Bulldozer-based Zambezi chip. If you already posess a board with that chipset, the frugal clocker in me suggests giving FX a try with whatever BIOS support your current board’s manufacturer supplies. See how it works. If you need the power saving features you’ll be lacking, by all means at that point go get yourself a 990FX board.
At the same time, if you want to have your BIOS/UEFI mature with Zambezi, go ahead and get a 990FX board. Manufacturers were quick to tout 890FX board compatibility, but how far will that go? Will any of them upgrade the BIOS/UEFI on a now-obsolete chipset past initial compatibility? As the magic 8 ball would say “Outlook not so good.”
Which brings us back to the subject at hand. The Crosshair V Formula is the absolute top of ASUS’ line of current AMD motherboards, and you’re going to pay a bit for that. Without a doubt, there’s a premium for having the best as well as a premium for all of the many features this board has. Currently it will set you back $229.99 (with free shipping) at Newegg. For what you’re getting, honestly, it’s not a bad price. A cheap motherboard it’s not, but if you’re looking at this board you’re looking for performance and features, both of which it excels at. If you’ve got the money to spend, the Crosshair V Formula is definitely worth the price.
