Asus P7F7-E WS SuperComputer Review

You wouldn’t expect overclocking performance from the workstation-designated Asus P7F7-E WS SuperComputer motherboard, but once you dig deeper you begin to find all the goodies that have made Asus motherboards so popular with enthusiasts.  Probably the single most attractive feature is the ability to run three way SLI or quad CrossfireX, but there is plenty more that makes this a premium board.

The important features to note are the SATA 6.0 GB/s, USB 3.0 support and the four 16x PCI-E slots for graphics cards.  Notice that these slots, along with the 3 PCI-E 1x, leave no room for normal PCI slots however this leaves a lot of real estate on the board for multi-GPU setups.

For overclocking, they incorporated 16 phase power filtering on the CPU and 3 phase power filtering on the IMC: most other boards only have 4 to 8 phases of power filtering.  They also have a copper heat pipe connecting the fanless heat sinks on the South Bridge, North Bridge, and power MOSFETs.

The included GP+ diagnostics card is great for benching because it contains the power and reset buttons as well as the boot code LEDs.  I’d rather these be included on the main board, but having them as an add-on card is better than nothing.  If you are going to be editing videos, you’ll appreciate the dual 1394b ports on the rear I/O panel.  I also like how Asus included two regular USB ports near the SATA ports which allow access when benching like front-panel ports on a regular case.

Compared to a normal P55 motherboard, the main physical difference is the support for ECC RAM.  This type of RAM is typically found in expensive servers where handling massive amounts of data without corruption is mission critical.  For the majority of us, regular non-ECC desktop RAM is more than capable of handling our data and overclocking needs.  I’d imagine that it is possible to overclock ECC RAM, but it doesn’t make sense to increase the strain on those chips if you are paying extra for the guarantee of stability and correctness.  Another side to the RAM that sets this board apart is that there are 6 DIMM slots, instead of the usual 4 that are on most dual channel boards.  This allows for more options to fit your budget, like adding in another pair of 1 GB modules if you happen to already have two pairs lying around instead of needing to buy 2 GB modules to increase the amount of RAM.

The BIOS was very easy to work with as the majority of the overclocking options were located on one page and did not require a lot of scrolling. The only settings important from an overclocking standpoint that are not on this page are the CPU Features – and even then, Asus has carried the Intel SpeedStep Tech option over to this Ai Tweaker tab for easier access.  The motherboard itself has an attractive color scheme and the extra LEDs (like the Heartbeat LEDs around the Asus logo) add some nice visuals.  The diagnostic LEDs (CPU, RAM, VGA, and HDD) are also useful when pinpointing a problem, but most of the time they are just there for looks.

Typical to several Asus boards, the software CD include utilities like TurboV, T-Probe, and EPU-6. Overclockers will find TurboV the most useful for their cause.  It moves most of the overclocking options from the BIOS to a nice interface in Windows so you can test new settings without rebooting.  There are several automatic overclocking tools in this utility, too, if you are feeling lazy.

I must admit, I did like how CPU Level Up didn’t just show you a percentage of overclock or assign random names to the profiles.  Instead, they labeled the levels by what processor it would equate to, like step 3 on the i3 530 (2.93 GHz stock) would be similar to a Core i5 661 at 3.33 GHz.  T-Probe is a little boring since it just shows the temperature of the power phases and lets you select between power saving and maximum power.  EPU-6 is a little more interesting, but again is for saving power, not overclocking necessarily.  If you want to underclock, you can actually do it very easily with this application.

This board also has Express Gate which is a tiny Linux based OS that can be loaded before the computer fully boots to quickly allow you to access the internet. I’ve always thought this was an interesting option as I’m a Linux fan, but I’ve never actually used it on my own computers.  I’ve also seen the MemOK! button included on other high end Asus motherboards and can be useful when installing new sticks and getting the board to recognize their timings correctly.

If you happen to be running extreme cooling (liquid nitrogen, for example) and you reach the maximum amount of voltage the BIOS will let you, then you’ll be happy to see the overvoltage switches at the top of the board, above the RAM slots.  Most overclockers will never need to touch these, but they are there for the select few who need to pump up to 2.1v to the CPU, 1.9V to the IMC, and up to 2.5V to the RAM.  When turned off, the BIOS can only set 1.7V, 1.7V, and 2.0V maximum, respectively.

Performance

For the performance tests, I’ll be using an Intel Core i3 530 processor (2.93 GHz) loaned to me by our very own Brollocks (thanks buddy!).

  • Motherboard: Asus P7F7-E WS SuperComputer
  • RAM: CSX Diablo 2x 1 GB DDR3-2000
  • Processor: Intel Core i3 530
  • Heatsink: Zalman CNPS9900
  • Power supply: NZXT HALE90 850W
  • Graphics Card: ATI HD 5550 DDR5

When I was testing, I hit a BCLK wall at 220 MHz and a RAM wall at 5x 200 MHz (2000 MHz DDR).  I could boot fine at 215 MHz BCLK and I could run memtest86+ for hours at 5×195.  No matter what I did with ratios and voltages I could not get past these frequencies.  I also found that the Core i3 processor did better with lower RAM frequency paired with tighter timings than higher speed and looser timings. Because of the 220 MHz BCLK wall, I was only able to max the processor out at 22×215 MHz, which is still a decent 62% overclock.

To compare, I’m using scores from hokiealumnus’ Asus Crosshair Formula IV review and my Biostar TA890FXE review.  Both of those reviews used the Athlon II X4 640 processor.  You can see that the Core i3 530 is mostly better at single threaded applications while the true quad-core in the Athlon II wins a few of the multi-threaded applications.  The Core i3 is better at single threaded applications because it’s clock speed is higher (4.6 GHz vs. 3.8 GHz).  The multiple thread tests prove that Hyperthreading does help but is not a true replacement for more physical cores.

Conclusion

If you have the money to drop $290 on this board and fill it with ECC RAM, a Xeon Processor, and four GPUs then you could quite possibly have yourself a super computer.  For the rest of us, whether using LN2 or air cooling, there are certainly less expensive options that will perform equally as well as the P7F7-E WS SuperComputer in benchmarks. The extra RAM slots available, generous amount of space for multi-GPU setups, and the offering of Asus’s full software toolset set this motherboard apart from many in its price range and may be the most important factors in your buying decisions.  For what it is, the motherboard performs well and does everything you’d expect it to do.  Because of that, I’m marking this motherboard Overclockers Approved. Thanks to Asus for sending us the board to review.

Nice review! Too bad I don't have the money for this beast.

Nice review. How high could you clock the RAM? I noticed you kept it pretty much at stock all the time.
Also did you use the plug in GP Diagnosis card?
