MSI GTX680 Lightning GPU Review

Today we get to look at arguably one of the most coveted models of cards for enthusiasts from MSI, their Lightning brand. For this implementation, all the features that come along with that such as more robust power delivery area and cooling to name two, have been applied to Nvidia’s venerable GTX 680. Let’s take a closer look and see how this one performs.

Specifications and Features

Listed below are the specifications listed from the MSI website. The important thing to take away from this is the factory core clocks have been upped to 1110 MHz with a boost of 1176 MHz.

What sets this card apart from the other GTX 680′s available outside of the TwinFrozr IV cooling solution (Xtreme Thermal), is a fully custom PCB sporting additional power phases, an 8+3+1 – (core/memory/pll) set versus 4+2+1, Unlocked Digital Power, GPU Reactor, and Military Class III components to name a few. Listed below are more details (sourced from MSI).


Unlocked Digital Power

- Unlocked BIOS: One click to unlock all protections for extreme overclocking
- Digital PWM Controller: More stable and precise voltage by digital signal
- Enhanced Power Design: 2X Power output for maximum OC potential


GPU Reactor
- An add-on device on the back of GTX 680 Lightning (Behind GPU) for the overclocking stability
- Provide 200% higher power capacity and eliminate power noise (ripple)

Xtreme Thermal
- Dust Removal technology on Twin Frozr IV keeps dust out for the best thermal condition
- Dual Form-in-one Heatsinks provide better heat dissipation and strengthen the structure

Military Class III Components

- Meet MIL-STD-810G standard to ensure the best stability and quality.
- Adopt CopperMOS, Hi-c CAP, Golden SSC, and Dark Solid CAP

To continue on my MSI marketing rampage, here are a couple of slides detailing more of the specifications and features. These slides detail the 12 Phase PWM (8+3+1), as well as showing the two(2) pin PCIe connectors versus the 8+6pin configuration on most other 680′s. The last slide in this group simply shows the GPU Reactor and how it fits on the card. This unit is very easy to remove/add in case you need to go SLI.

One of the major features here (but not pictured) is the use of a CHiL voltage regulator to control, well, voltage. Remember the reference cards use a dynamic Vcore and max out at 1.175 V which can potentially limit your overclocking headroom. Future releases of MSI Afterburner (no ETA, but soon!) should allow us to break through that barrier manually so we can get back to the type of overclocking enthusiast are used to. I have to say that is a welcome addition to those who do not want to or just don’t have the skill sets and tools to hard mod the card. So lets hope the voltage one can apply is significantly more. I’m personally thinking 1.35 V would be generous.

MSI brought the Twin Frozr IV (further mentioned as TFIV) cooling solution  to the 680 to keep temperatures down. The TFIV uses two 100mm PWM fans with propeller technology to move “up to 20% more air” as well has having two 8 mm “super pipes” flanking the middle of the heatsink array and nickel-plated copper base. The solution is claimed (by another slide not pictured  here) to be 16 °C cooler and almost 7 dB quieter to whatever card they compared against (reference?). The solution is quieter and more effective than the reference coolers that’s for sure.

MSI’s higher end cards give you more overclocking flexibility by implementing their 3×3 OC kits. Triple overvoltage, triple temperature monitoring, and triple voltage check points (all include core, memory, and PLL).

Starting off looking at the retail packaging, the second thing you will notice, after the large packaging, you can see they are keeping the F-35 Lightning fighter theme gracing the cover as well as showing the model type, “GTX680 Lightning” on the front. Moving to to the rear of the packaging covers typical things like minimum system requirements, as well as some of its major features. This box has a flip top lid with the upper panel going over more features like Military Class III components, Unlocked Digital Power, and the 3X3 OC kit. The bottom gives you a sneak peak of the card inside as well as listing a even more features.

Inside the retail packaging, the card was packed well using  form fitting foam sitting in an anti-static bag nice and snug. Towards the front the include accessories reside (DVI to VGA adapter, 6 to 8 pin connector, SLI bridge and more importantly, the voltage check cables).

After getting it out the box, you can see the card is using the TwinFrozr IV cooling solution sporting two 100 mm fans. These fans use an ‘anti-dust’ feature which spin the blades the opposite way (clockwise) upon power up to blow any loose dust off the heatsink.

Flipping the card over you see the now familiar GPU Core Reactor help keep more stable power supplied to the GPU. Its location is right behind the GPU to more effectively get the power where it needs to go. I’m not a huge fan of bling but this unit glowing blue I cant say I mind too much. Also on the backside are LED’s that show the active phases for both the core and memory. On the default bios the amount of power phases used varies upon load. When switching over to the LN2 bios all LED’s and phases are lit up and ready to roll.

Taking off the TwinFrozr IV heatsink reveals this isn’t your mamma’s reference board. Power plane fortification in the way of the 8+3+1 setup (core/memory/pll) mentioned in the specifications and features section is pretty obvious. You can see the necessary components such as the memory and power components all have a heatsink on top of them to help keep cool.

There’s not too much on the backside outside of more supporting components for power delivery. Moving on to the last picture of the base of the Twinfrozr IV heatsink you can see the pipe configuration with the 8 mm monsters flanking smaller what looks like 6mm pipes in the middle of the nickel-plated copper base to whisk the heat away from the GPU.

Wiping off the liberal application of Thermal Interface Material (TIM), is the  GK104 core fed by the 8+3+1 power configuration which uses the Copper MOS(fets) which run cooler, have a higher current capacity, Hi-C (High Current) caps, and Golden Solid State Chokes all helping in achieving potential superior overclocking ability. The last item pictured is the GPU Reactor core board sporting its additional Hi-C caps.

Overclocking Software

Most are familiar with MSI Afterburner so I wont go in to much detail here. One of the differences you may notice below however  is that it doesn’t list the clock speeds or voltage where you can make adjustments. Instead the value is just at zero(0+) so you increase the default values PLUS what you set the sliders to, so its an offset basically.

Another release will be coming out soon to allow one to push past the normal 1.175 V limit. I think this is a HUGE addition to those that may be nervous about volt modding video cards and would like to push past the 1.175v limit. How high it will go remains to be seen, but I hope its in the 1.3+ V range personally. The next version will also unlock the ability to change all three voltages with this card and really allow it to stretch its legs across the core and the memory.

MSI Afterburner 2.2.2

Synthetic Benchmarks

This is my first review since we have updated our review methods and have since dropped 3DMark06 as it was getting a little long in the tooth and was wholly bound by the CPU. All that remains in 03, Vantage, 11, and Unigine Heaven (Hwbot version) respond well to the GPU.

To start first see what will mostly be, and as most expect, a reoccurring theme of the MSI GTX680 Lightning beating out its reference based peer and of course its little brothers, the GTX670 SC and GTX670 Direct CU II. There are very little differences here between all the cards results however.

3DMark 03 and 3DMark Vantage

3DMark 03 and 3DMark Vantage

Stepping on over to 3DMark 11 we see the Lightning leading the pack again…and the same goes for Unigine Heaven as well. Although the monster overclock on the GTX670 Direct CU II managed to pass up the 680, that is how close these cards really are.

3DMark 11 and Unigine Heaven (Hwbot)

Game Benchmarks

Switching gears and moving to games, you can see we also changed this section up a bit as well. We got rid of Dirt 2 and Hawx 2, and replaced them with much more modern games such as Battlefield 3, Batman: Arkham City, Metro 2033, Dirt 3, and Civilization V. This selection should give readers a fairly good idea of how video cards perform across a variety of modern games and genre’s of games.

To begin, not much changes here from the synthetic testing above. The GTX680 Lightning is leading the pack in most cases. In Alien versus Predator though the stock score came in a bit lower than the rest, but that could be in the drivers. In Batman and Battlefield 3, the Lightning asserts itself as the leader. All games in this list are easily playable with some good eye candy at 1920×1080 resolution which is what one would expect from this caliber of card.

Alien v Predator, Batman: Arkham City, Battlefield 3

Alien v Predator, Batman: Arkham City, and Battlefield 3

When looking at the results below, Civilization V has another one of these peculiar results in that the 670 manages to beat it out here. Again I’m chalking this up to driver issues. Moving over to Dirt3 and Metro 2033, we see it right back up at the top. Even Metro2033, the GPU killer, comes in at a playable for most frame rate in the low 30′s.

Civilization IV, Dirt3, and Metro 2033

Cooling and Power Consumption

For our power consumption tests, we used Heaven and 3DMark 11 to find the peak consumption through those tests. Compared to some monster cards in the past, you can see the newest generation of high end cards comparatively sips on power. At stock speeds and voltages, the max load was an anemic 308 W. When flipping the LN2 switch and pushing the clock speeds and voltages on the GPU, that rose 321 W peak in 3DMark 11 with 316 W in Heaven. A quality 500 W PSU would  be plenty to support this card and overclocking both it and the CPU.

For the temperature testing, we use the same benchmarks in 3DMark11 and Heaven using the default fan profile. 3DMark 11 is faster and doesn’t heat up the GPU as much as well as having small breaks between runs, while Unigine Heaven takes a long time and doesn’t let up until the end. At idle with the temperatures normalized to 25 °C, the MSI GTX680 Lightning sat at 28 °C and 31.5 °C (stock and overclocked) with the fan on auto (30% at idle). When in 2D mode the card drops down to 0.987 V and lowers the core speed significantly to save power. This card on auto peaked around 65 °C while overclocked. The fan spun up to around 45% or so at that speed and was barely audible over my system fans.

Pushing the Limits

One of my favorite things to do here is to see how far our review card goes. Considering at stock speeds you already have a boost of 100+ MHz over reference core clocks, I didn’t have too much faith in pushing this card further. I probably should have reserved judgement a bit as I was able to push this card to a stable 1210 core clock and +225 MHz on the memory (likely could have gone further). The resulting core clock resulted in a boost clock of 1302 MHz. Couple that with a solid 4.8 GHz overclock on the 3770K Ivy Bridge CPU, and that brings me to some solid results listed below.

While this specific sample may not scream on air, its really not made to do so…on air. With the voltage read points, LN2 BIOS switch that disables protection settings, as well as the power delivery area on steroids, this  card really should be taken cold to reach its full potential.

3DMark Vantage - 38,528

3DMark Vantage - 38,528

3DMark11 - 11,158

3DMark11 - 11,158


Overall MSI has put out another great product in its Lightning series using Nvidia’s new Kepler architecture. The differences in board design such as increased power phases allowing more and cleaner power to get to the GPU, voltage read points, the GPU Reactor, and the TwinFrozr IV cooling solution, all make for a much better than stock solution in the overclocking department. One minor downside is waiting for the new release of MSI Afterburner (2.2.3) to come out to use all the functions; specifically it is rumored to have voltage control beyond the 1.175 limit most are used to.

The MSRP for this card is $599.99 and is currently priced that way at Its not the most expensive GTX680 out there (an EVGA model holds that honor at $629.99), but it certainly is up there in the number two slot. You just have to remember what this card is made for and that is pushing the limits with superior hardware behind it than reference models and most, if not all, aftermarket boards as well. You get what you pay for and there is a premium for better components.

Pricing aside, you have a monster of a video card even with stock cooling and voltage limits. Where this card really will earn its keep however is when it is under water or especially extreme cooling with the new MSI Afterburner release. If you want the best GTX680 you can get, this MSI GTX680 Lightning certainly has a good argument for it.

Nice review, Joe.

Super jealous you got to review this piece of hardware. I better see some sub-zero results soon!
bluezero5's Avatar
the question really is..

can MSI afterburner 2.2.3 really alt the voltages of the GTX 680.

cause seems like nVidia really dont want people doing that this moment...
xander89's Avatar
yer i started a thread about this MSI 2.2.3 the other week. I think we will get voltage control. I know the reference 680 pcb 670's are able to accomodate it ( and ofc all of the 680s) so i think we just have to wait. I think its coming, just how sooonnnnn

Dammit that card has about 500 more points on the gpu score @ 1301 than my 670 @ 1330 ( im around 10880 atm). Must overclock my card moarrrrrrrr

Nice review Earthdog! Since I'm gonna build a new system later this year, I gotta ask and you probably know.

Whatever happened to the G110 chip cards? Was supposed to be a even better GPU chip coming out later this year?

Any 'internets' on it?
xander89's Avatar
I heard that it was the plan to release the G110 chips but because of the performance increase over the the 7XXX amd series there wasnt really any need. Why roll out the G110's when the G104's stomp all the competition already It wouldn't make much business sense to bring out their trump card so soon after the G104's. not really any useful info in it, but just to make you drool

I think they are just biding their time until AMD come out with a response to the 6XX cards. My 2 cent anyhu

Also i didnt say before but top knotch review ED
Janus67's Avatar
To be fair, I think 'stomp' is too strong of a word. The 7970 and 680 trade blows back and forth depending on the benchmark (it isn't like Intel vs AMD).

I agree though, they don't have much reason to run G110.
bluezero5's Avatar
when talking about GPUs, it is hard not to take fanboyism out of the equation.. but I will now attempt.

HD7970 is a great card. with voltage unlocked, it can actually rock the GTX680 on benchmarks. However, for me, the goodness ends there. AMD did a HORRIBLE job with the drivers and other little things that makes the GPU a good experience. NVidia on the other hand has much better Drivers and support, and now G104 is on-par with AMD's latest. (which is a triumph alone). However, nVidia deciding to lock the voltage on GTX680 is giving a leakage to HD7970. I have a volt mode GTX680 card, and it is a MONSTER, I have increased the power by 150% and is having a stable clock at 1350Mhz currently. (can probably go for 1375 or 1400.. but I want to see others doing it, and NOT ruining the card first. lol.)

ATI cards use to always give me a feeling they have a slight upper hand over nVidia..
but of late, nVidia seems to be the winning company. Just last night AMD actually announced a huge revenue downgrade for themselves.. overall.. I feel AMD has potential, but they just keep mismanaging their company from winning.. and now, nVidia has finally catched up.. and might win the game for the next few years.
Janus67's Avatar
Yeah, a definite unfortunate truth. They've always had more issues with their drivers than I've had with using nVidia cards (over the time I've been building computers -- about 13 years now (insert shocked face) I've used about 50% of each).

Really sad about the earnings for AMD... as I'm a stock holder (as well as nVidia and Intel).
EarthDog's Avatar
MSI AB 2.2.3 is supposed to be able to push past the 1.175 voltage limit that is on most cards. This will not work on every card though as some do not have the power management chip like this card does. Thats all the information on that I can share though.

@ Conundrum - The GK110 question was answered properly to my knowledge. Supposedly its later this year, but that is still a rumor.

EDIT: Thank you for the kind words regarding the review.

Nice review earthdog
xander89's Avatar
yer i know what you mean, but i suppose im talking real world gains ( GAMESSSSS ) bechmarks and raw gpu processes yer AMD swings it / edges it on the 6XX's. But at the moment i would say a lot of people would take a 670 /80 over a 7970 ( i was trying to decide between the two for a while) but considering the 680 will edge it in most games ( and with manual voltage control round the corner which will probs put it far beyond what a 7970 can do) + much better drivers etc is pretty clear cut.

Oooo zero did you volt mod it yourself? ( the 680 that is?) and was it hard? either way i dont think ill do it, rather just wait for 2.2.3, but im just interested either way

alo yer ED i was reading about the power management chip, im pretty sure most of the 670's with 680 pcbs have it. I'll try and dig out the thread i was reading.
Conumdrum's Avatar
Been reading up on the GK110 GPU chip. I thinks it's going to stay on the non-gaming side.

So, I'll be beginning to look at a new build (on air hopefully) for an October build date. My wifes PC is old and slow, and she wants my leftovers.

Probably a 690, wish they had a 4gb per chip or do they?
xander89's Avatar
I havent seen a 4gb per chip 690 that would be a beast. I dont know what i would prefer a 690 or 2 680s. Hmmm decisions. thats a shame that the gk110's are going to stay on the non gaming side. I suppose its a smart move by nvidia though. by the time AMD have a response to the 6XX's then i suppose nvidia will have another lineup ready.
Woomack's Avatar
nice review
I would probably buy one but I already got HD7970 Lightning mainly because I saw starting price for GTX680 Lightning in Europe ...
Conumdrum's Avatar
I can't say the GK110 isn't going to be, but we have heard nothing since the new cards came out, I did find two references that it's a great computatiional chip and might stay that way.
bluezero5's Avatar
overall, I remain disappointed the afterburner 2.2.3 is still not out..

I will like it more when I see the final OC results.
xander89's Avatar
ditto, they should have released it with this card. Wt numpties. i dont think its too far away though *crosses fingers* cant wait to clock my 670 past 1400, will probably hit the magic 11k mark in 3dmark11

I don't want to bum everyone out but here is a e mail from my MSI contact on the AB

the developer is currently on vacation.
According to the source from guru3d forum, he will update it when he returns on Aug therefore we don't know when exactly.


Also I havn't received the total unlocked bios from MSI yet so the best you can do with the LN2 on board bios is 1.21v to the GPU good for 1300+ or so if you have a good chip.

Looks like we will be in the dark for another few weeks unless you want to hard mod the card
TURN & BURN's Avatar
All Im saying is I received that e mail yesterday after my contact relayed to HQ for the AB-X which I have a signed a NDA on file w MSI and up till now I have everything for the 7970's including the unlocked special bios, I trust my source highly especially since he knows I will be attempting records soon w IMOG, shipping all my equiptment there for AUG 2nd through AUG 5th . I was told to sit tight.

this afterburner only for those with MSI lightning cards with voltage regulators.
the rest of everyone, is it a volt modding weekend.
xander89's Avatar
only msi cards? really...? I swear pretty much every 680 has the appropriate voltage regulator to allow manual voltage control? if not does that mean we are doomed to never have voltage control? If they do how soon do you reckon it will roll out to other 680/70's

Also im so hungover its unreal, and this has just made me really grouchy
bluezero5's Avatar
i already downloaded it to check.
on regular cards, the voltage up range still just 1.175V

and yes, I was disappointed, I was hoping this can reach beyond MSI lightning cards too.
