Just found this in Guru3D's latest 590 review (Gigabyte). Looks like, in crysis at least, the original release drivers were higher performance than the later ones. Someone else speculated that maybe nVidia pushed it too far with those original drivers trying to compete with the 6990. This doesn't prove it, but it does supply some evidence to that theory. I wonder how many of the benches were run with the original drivers and not redone?
This makes no sense. If the card is over-engineered then there are expectations for it. Seems like god-made and forced cold air would be greater engineering than a water block.I bought the card from a freind. It was a good chip that I knew I could get to the 1ghz mark with.
I don't care if god engineered my cards's power stage and it had a 10,000 watt air conditioner attached to it, I STILL WOULD NOT PUMP 1.2 VOLTS INTO IT, ESPECIALLY IF IT WAS A BRAND NEW, NEWLY DESIGNED, 700$ DUAL gpu CARD.
ONLY RETARDS DO THAT WITHOUT WATERCOOLING.
We first heard back from NVIDIA and they urged that we don't increase the voltage with the reference cooler as it was designed for a 365W card and that over-volting the GPU would push the cooler beyond its rated specifications.
Weve designed the GeForce GTX 590 to provide a great combination of performance, acoustics, and temperatures in stock form with our standard cooler. Like other GeForce GPUs, overclocking is also available for our customers who want to crank up performance even further either via our add-in card partners or via system builders, and of course for end users who would like to tweak the card themselves.
In the latter case however, we recommend anyone using the GTX 590 board with our standard air cooler stick with the default voltage while overclocking. This will ensure the best experience and reliability for our customers.
For end users who do wish to overclock with overvoltaging, we advise watercooling. NVIDIA has worked with several watercooling companies to develop waterblocks for GTX 590 , and these solutions will help provide additional margin for overclocking, but even in this case we recommend enthusiasts stay within 12.5-25mV of the default voltage in order to minimize risk. These are guidelines only any overclocking/overvoltaging can void your manufacturers product warranty. - NVIDIA Public Relations
It sounds like NVIDIA is really not advising extreme overclocking on the GTX590 unless you have water cooling and we know that EVGA will have a water cooled card available down the road. We contact our friends over at ASUS and they said that you can over-volt the card, but you just need to manually set the fan speed above 60% to ensure proper cooling. You can see what ASUS had to say about overclocking below.
* By default without voltage adjustment or fan adjustment you should generally be in the range for 660 to 670 for the GPU. Anything more than this while potentially stable under stress testing / benchmarking should have a manually set fan profile exceeding 60% to ensure sufficient cooling.
* Utilizing Voltage Tweak internally we have seen clock speeds in the range of 740 to 780 (this is using a vcore setting of 1.035 to 1.065) varying on the GPU. IT IS IMPORANT TO NOTE any overclocking with voltage exceeding 1.000 is strongly advised that the fan be manually set to ensure sufficient cooling performance.
* It is not advised to generally exceed the 1.050 to 1.065 vcore range as this begins to meet the limits for the OCP/OVP mechanism on the card. Exceeding these values without disabling OCP/OVP or having superior cooling could affect the lifespan and functionality of the card/gpu.

There is no magic in real life, you gotta loose something to make something smaller...
I noticed this card has 3 dual link DVI connections. Does that mean I can run 3 seperate monitors for desktop work? I game only on the primary monitor.

^^ This , i know already of 5 dead cards from my friends that died at stock voltages stock clock running heaven and Vantage benchmark , add 2 more testing on LN2 and 2 more on H2O = 9 cards already , how many dead 590s have not been reported ? this card cannot even handle 100% full load on GPU for long periods of time , yes it will blow up in smoke even at stock voltages and stock clocks. Nvidia should make a recall on this cards me thinks :/ , so many cards 590s have died and since has not been reported it looks thats just a few cards , the truth is , its going to happen soon or later , its like a time bomb , this card its a total failure and im sad i had high expectations on this card. Ill wait for the next 28mm cards to be release , as of right now 590 or 6990 are not apealing to me at all.
wtf, you SHOULD THANKS HIM, saying a professional reviewer retarded is an insult to enthusiast community, and are you basically saying that overclocker retarded too because they push their hardware to the limit, and don't ever use that GPU-Z because the Man that coding that program is retarded, even tough countless other reviewer use it even anand.
what you are saying is really an insult.
and i will just leave it here :

he was a part of HWbot team a respectable overclocker group, so HOW DO YOU EXPLAIN THAT ??
Impossible!!!! All 590's can handle 1.05-1.1 and O/C to 800MHz!!! Pay no attention to the facts that reviewers have put in black and white. [/sarc]
Seriously, this is not the first of nVidia's new generation that have had this problem. It's just the latest.
@happymedium, I notice that you didn't buy a reference 460, or a Palit, or some other cut rate bargain design. You bought the MSI Hawk. The 460 with the most over engineered power stage and one of the best coolers on the market. Why don't you just be honest with people and tell them to hold off until there's a Hawk or equivalent model available. We all know the potential of the 590. The reference model just doesn't fulfill that potential.
This is assuming the OCP in the drivers doesn't hold it back. Which I'm concerned it might (dumb way of doing it).
You can run 4 monitors with 3 dual link DVI and one Display Port connection for desktop work. Or 3 monitors for Nvidia Surround.

Crysis is pretty demanding on the GPUs. I wonder if they simply changed the OCP values and Crysis is actually causing the OCP to kick in on the latest driver set.

How would you have reacted if he had blown up a 6990 by pumping 1.2v through it?
Do you know the stock voltage of a 6970? They use up to 1.4v when overclocked, so I would say 1.2v is fine. Now to put the shoe on the other foot. If the 6990 was released today and this Wizzard guy pumped 1.5v in the card and blew it up within hours,I would still call him a retard, especially when the 6970 would not handle that voltage (1.5v), just as we all know a gtx580 would not handle 1.2volts.
Dum, stupid, irresponsible, mabe retard is the wrong word, but I think you get my point.
I believe you because you say so.... NOT!

To clarify, the respective percentage increase for each card when W1zzard overvolted the cards looks like this:
GTX 590 stock = 0.983V overvolt = 1.2V % increase = 27.9%
HD 6990 stock = 1.12V overvolt = 1.4V % increase = 25%
Results: 6990 ran fine, 590 died.
So are you saying that extra 2.9% was retarded and was responsible for the 590's death? Or could it be that the 6990 is just a more robust design (especially considering the other 590s that blew up with much less voltage)?

There is a reason Msi afterburner puts a cap of about 1.087 on all Nvidia cards, because they run at lower voltages at stock, and we all know this.
On any Nvidia card you must hack the bios to overvolt to 1.2v.
I'm sure if Wizzard is the genious that everyone thinks he is HE KNEW THAT.
Are you saying he did it on purpose?,because if he did he would be called alot worse things then retard.
Dum, stupid, irresponsible, mabe retard is the wrong word, but I think you get my point.

how do you know the limit are 1,2 volt ??? you SHOULD THANKS him to find out that the limit are 1,2 volt
Do you max out the cpu voltage in your motherboard bios ? Because it does not stop you ?
No you missed my point totally.
Have you EVER seen a 1.2v air overclock with a gtx580 without a modded bios and hopefully on water? I hope not, or someone has a extra special chip or a fried card. So why on earth would you try it with a dual gtx580 card?
I will tell you why you havent seen it done before, the 580 would start throttle down before you reach those levels
