EVGA GeForce GTX 580 Classified: Overclocked
Manufacturer: EVGA Full Disclosure: The product sample used in this article has been provided by EVGA. The EVGA GTX 580 Classified is one of the most powerful single card solutions on the market. With a 14+3 VRM design, a new cooler and the Classified logo many users want to know "How far can the EVGA GTX 580 Classified go?" Benchmark Reviews is here to answer this question armed with the Beta EVTUNE software to allow us to really push the voltage and is yearning to see how far this card can go. So please join us as Benchmark Reviews overclocks and benchmarks the EVGA GTX 580 Classified. When NVIDIA introduced the Fermi architecture in April 2010 with the GF104 and the GTX 480 it ran hot, and was very power hungry. Fast forward to November 2010 and NVIDIA is releasing the GTX 580 using the GF110 which uses the same Fermi architecture but now has access to all 16 streaming multiprocessors while at the same time bringing down power consumption and more importantly giving off less heat. Since then many radical designs have been released to help further control heat output but few have been designed from the ground up to set overclocking records. This is where EVGA comes in with its Classified line for its GTX 580 which was built from the ground up for extreme overclocking using LN2 and Liquid Helium Cooling. EVGA included a 14+3 VRM design, 2 x 8 + 1 x 6 power inputs, a second BIOS developed to deal with the Fermi cold bug, an 8 cm blower fan, and a somewhat redesigned heatsink. To top it off EVGA has also added a generous 73MHz overclock to the core clock bringing the core clock on the Classified to 855Mhz.
Since this is a top of the top of the line card we will only be using the most powerful of benchmarks. With a majority of upcoming titles being designed to take advantage of the DX11 APIs, Benchmark Reviews will focus on only the most powerful of DX11 benchmarks both synthetic and real world.

Based on newegg reviews owners got 900-920 mhz at default volt. I'm hoping to get the same. Extra 20 to 40mhz for a 0.2 volts extra is too much. Did toy try to oc without volt tweaking?
Can't wait to bench mine.
More seriously, I doubt you could get to 1000 watts without those liquid-He/Ni cooling ideas. Still, if you could get it to 600 or 700 watts using air or water, that would be amazing. It's already drawing more power than most people's entire systems - it'd be both humorous and educational to see if it could outdraw most enthusiast systems.
Anyway, another enjoyable article. You guys run an excellent operation here at BMR.
I can not test for anything over the power draw I had on during this test due to thermal constraints. Even so during our test I was drawing almost 500w just for this card.
Thank you for the compliment it means a lot to know that our readers appreciate our work.
Nice to see an unashamedly "enthusiast" review.
Seems a little late to the party ( evga ). I can't see getting the classified when Kepler is around the corner now ( the first round of consumer cards and then the enthusiast cards soon after )
FYI Even if you wants to buy this gpu you can't it has bin sold out since launch and available in limited quantaties. Meaning when kepler hit I should have no problem selling the thing due to the limited quantities and demand @ a good price. Besides how would I play skyrim with all the hd mods out there already as well as bf3 @ max!

I hope not another fermi
OC is like over speed limit.....if ya going 10% over the 60 mph peed limit, that's 1.10 x 60 or 66 mph ....66/60 = 1.10 or 10% over speed limit
% Overclock = 100 x (OC Speed / Stock Speed - 1)
100 x (940/772 - 1) = 21.76%
Or another way ....
% OC = (OC speed - Ref Speed) / Ref Speed
(940 - 772) / 772 = 21/76 $ same answer
