Already so impressed with what the MARS II has to offer, we knew what had to be done. Using GPU Tweak, the overclocking software that replaced ASUS SmartDoctor, it was time to see just what kind of overclocking performance could be had from the new MARS II from ASUS.

I'm expecting good things from the card to be honest. For starters, the cooler is just massive on the card and we already know it does a fantastic job of cooling the two GTX 580 cores present. With the help of that cooler, we're hoping that we'll get some good breathing room on the cores.

The other thing is, compared to a GTX 580 SLI setup, there's no card squashed up against another. Because we're dealing with two cores on the single card, our fan has got heaps of breathing room making sure plenty of cool air can be drawn in.

Finally; it's an ASUS product and if past experience is anything to go by, we should see some strong performance coming out of the card. Because we've already looked at the card in such detail already, we'll just be getting straight into the overclocking side of things. So, on the next page we'll check out the test system setup and the overclock we managed to achieve.

Once that's done, we'll just get straight into the benchmark line up and see what kind of performance increase we're able to get out of the MARS II when the card is overclocked. That just about covers everything, so with haste, let's get into it!

Test System Setup and Overclock

ASUS MARS II 3GB Dual  GTX 580 Video Card Overclocked 99 | TweakTown.com

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital and Corsair.

Why do you use a Z68 platform with x8 / x8 instead of an X58 one with x16 / x16? Z68 vs X58 - Which is The Better Gaming Platform?

The testbed side of things is identical to that of the standalone MARS II review and the comparison line up is identical with the MSI GTX 580 SLI setup included, the Sapphire HD 6990 and the MARS II at its default clocks.

Using the new ASUS GPU Tweak software to overclock our MARS II card, we ended up with our cores coming in at 862MHz. This is 80MHz up on the out of the box speed and 90MHz up on the default GTX 580 speed. This means that of course our Shader clock has been bumped and that now comes in at 1724MHz.

As for the memory side of things, we pushed our 3GB of GDDR5 up to 4208MHz QDR which is 200MHz QDR up on the default out of the box overclock.

This isn't a bad overclock at all and you have to remember that we're dealing with an 80MHz core increase on two cores along with two sets of Shaders. It helps make the overall overclock a bit more powerful and it's something that's worth remembering.

So with that done, let's find out just what kind of performance increase we get from the MARS II when it's been overclocked.

Let's get started!

The FPS Numbers Explained

When we benchmark our video cards and look at the graphs, we aim to get to a certain level of FPS which we consider playable. While many may argue that the human eye can't see over 24 FPS or 30 FPS, any true gamer will tell you that as we climb higher in Frames Per Seconds (FPS), the overall gameplay feels smoother. There are three numbers we're looking out for when it comes to our benchmarks.

30 FPS - It's the minimum number we aim for when it comes to games. If you're not dropping below 30 FPS during games, you're going to have a nice and smooth gaming experience. The ideal situation is that even in a heavy fire fight, the minimum stays above 30 FPS making sure that you can continue to aim easily or turn the corner with no dramas.

60 FPS - It's the average we look for when we don't have a minimum coming at us. If we're getting an average of 60 FPS, we should have a minimum of 30 FPS or better and as mentioned above, it means we've got some smooth game play happening.

120 FPS - The new number that we've been hunting down over recent months. If you're the owner of a 120 Hz monitor, to get the most out of it you want to get around the 120 FPS mark. Moving from 60 FPS / 60 Hz to 120 FPS / 120 Hz brings with it a certain fluidity that can't really be explained, but instead has to be experienced. Of course, if you're buying a 120 Hz monitor to take advantage of 3D, an average of 120 FPS in our benchmark means that in 3D you will have an average of 60 FPS, which again means you should expect some smooth gameplay.

H.A.W.X. 2 has always been a little funny when it comes to overclocking and quite often we see performance fall back just a little. Here is no different; fortunately we've still got very strong FPS across the board.

Temperature Test

Temperature Tests

The temperature of the core is pulled from MSI Afterburner with the max reading used after a completed run off 3DMark Vantage and the Performance preset.

ASUS MARS II 3GB Dual  GTX 580 Video Card Overclocked 40 | TweakTown.com

Throwing more volts through the card and we continue to see ridiculously low temperature numbers on both our cores. In this situation the card's actually running slightly cooler and that's no doubt due to the fact that the fans are working a little harder than at stock.

Sound Test

Sound Tests

Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.

After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).

ASUS MARS II 3GB Dual  GTX 580 Video Card Overclocked 41 | TweakTown.com

While overall noise does indeed jump, we're still a massive 10dB below the HD 6990 and you can see overclocked, nothing can touch this card at these noise levels. It really shows us the strength of the cooler.

Power Consumption Tests

Using our new PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly known as to our readers, we are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into AC wall socket).

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

The other thing to remember is that our test system is bare minimum - only a SSD hard drive is used with a single CD ROM and minimal cooling fans.

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

ASUS MARS II 3GB Dual  GTX 580 Video Card Overclocked 42 | TweakTown.com

Power draw jumps again and we manage to be drawing a massive 709 watt off a single card solution which is just insane. Of course, as we said in our initial review, if you're buying something so high end, we like to believe that you've made the jump to a high quality power supply like the Corsair AX1200 which is what we use here.

Final Thoughts

Overclocking is a bit of a funny thing and depending on the way companies set up the fan profiles can depend on the kind of overclock you're able to achieve. We can see for ASUS, silence continues to be something they want to concentrate on and even when we add more voltage to the card, the fans don't ramp up to these unbearably loud numbers.

The problem with that setup, and we see it a lot with Palit cards, is that the overclock just isn't going to be as strong versus a company that tells its fan or fans to ramp up to 80%+ when the cores start to really heat up. The thing is, though, you find that the MARS II creates a much more bearable card in gaming because it doesn't shoot up to 80dB.

Instead, you can give yourself a nice overclock that yields a good performance boost, and you get a setup that is outputting the same noise levels as a stock GTX 580 in SLI setup. Not only that, though, we've got a card running cooler than that stock GTX 580 SLI setup and that's where so much of the appeal to this card is when you step outside of the performance side of things.

It's worth mentioning, though, that if you want to get into the benchmarking side of things you can always hit the little 100% fan button and crank up those two fans to full speed. That will help bring with it lower temperatures which will in turn give you a larger overclock. The good news is that even at 100% the fans aren't that bad thanks to the fact that ASUS have opted to use 120mm fans.

At 100% fan speed the MARS II is less irritating on the ears than the HD 6990 in its AUTO profile thanks to the size of them. If you wanted to, you could crank the fans up to 100% every time you gamed if you wanted the biggest overclock, but I'm not sure why you'd bother. Everything we throw at the card today runs like a dream and the need for even more speed is probably quite unnecessary. Of course, that doesn't mean you can't do it.

Overclocking the MARS II just simply brings us more performance than what we've already got, which to be honest is more than you'll probably need. Of course, that all doesn't change the fact that we just love to see how much more performance we can get out of the card and the fact that we're over 850MHz on both cores and getting noise levels in line with the reference GTX 580 setup in SLI is amazing.
