This is driver problem. 267.52 has no OCP! With 267.71 everything is fine.

High-performance graphics card Geforce GTX 590 balances on the verge of what is practically possible to handle in terms of power consumption and heat development. Even worse is the situation when overclocking.
In order not to risk the components damaged are blocks built in drivers to say from when limit values are exceeded. SweClockers testers Jonas Eriksson tells what happened when the graphics card you take 12 000 SEK went up in smoke.
The first graphics card gave up the spirit when I user overclockable with the increase of the voltage to the GPU. I was thinking not so much more on it, after all things that can happen and there are always Monday specimens, in particular as regards the early "samples".
Shortly afterwards snappade Andreas up more suffered the same misfortune and we decided to explore it all together with Nvidia.
An additional video card had to be sacrificed in order to come to the conclusion that it is driver 267.52, which is the culprit. The experiment was repeated with newer 267.71 and then worked Nvidias safeguards that they would.The essence of it all is to install the latest software from Nvidias website and at all costs avoid the driver that is included in the box, which is precisely the wrong version 267.52. The who plan to overclock should also make sure that you have good ventilation in the chassis and be aware that your warranty is if frequencies are increased over specifications.

yeah but... that still doesnt explain why the card blew...
he increased voltage from 1v to 1.2v and used stock clocks... and that blew the card? then the pwm seems to be pretty whimpy, no?

if it blows almost instantly with 1.2v and stock clocks, how safe is it to overclock the card and run it at 1.1v? how long until it pops?

overall it seems 6990 and 590 are very close to each other performance wise... enough to not care, each will do fine if you need that much horsepower... the advantage of 590 is that it has more overclocking headroom left... but it seems the pwm is kinda whimpy and cant feed the gpus when you actually push them? :/

for day to day users i think the 6990 is a better option... for enthusiasts the 590 is a better option but it looks like it will need better pwm cooling and some mods so it wont hold clocks back.
has anybody played with a 590 on cold yet?
can the pwm handle it?

EDIT: well, other reviews say the 590 is almost at the same noise level as a 580... and they didnt have any problems overclocking it with stock voltages...
in that case the 590 would be the better day to day card...

hmmm curious about more info on why some 590s blew up...

Could simply be a bad component on that particular unit, no way to know if there is a overload situation unless there are others seeing the same failure.

check the article, according to w1z, yes, others are having similar issues with cards dieing from minor voltage changes :/

idk... it sucks that no review i read so far put up a sound sample of the cards under load... both cards are noisy, so the 590 being less noisy might be pointless if its still noisy... if the 590 is acceptable and the 6990 is notably louder, then that would indeed make the 590 look more attractive...

i have a feeling the 590 is less noisy but it wont really make a difference in a well ventilated case whether its a 590 or 6990... and these are for gaming rigs with nice sound systems or headphones, so...
then add to that the apparently more robust and beefier pwm of the 6990, a very open and adjustable power throttling menchanism, the easy overclock switch for 6970 clocks and higher voltages... and to me it seems the 6990 is the better option...

for people who dont overclock though, i think this is the closest ive seen nvidia and ati with their highend cards... ever... same price, almost identical performance and power consumption and temperatures overall...

With all of the issues with burnt up vrms on GTX570 I'm really not surprised. I just don't understand why Nvidia is cheaping out on the voltage regulation on expensive, power hungry, high end cards

I would say pumping the voltage on any component poses risks, your mb has enough voltage range to toast your OC marketed cpu or OC markted memory if you use enough juice, or even the pwm on the mb itself.

Just because you can doesn't mean it's going to be ok if you do juice a part.

If people are popping cards with a minimal voltage boost then who is to say how this will hold up to long term day to day use. I also think that a $700 video card should be built with enthusiasts in mind like 6990. There is no reason that there isn't some sort of hardware over current protection like we saw kick in on 4870, etc with OCCT.

i dont get why NV continues to sell anything thats gf100 based, they have gf104 based cards that have the same shader count*shader clock rating but then they are not rop starved and use less power. like the 590 uses an under clocked rop starved gf100 when they had the stock clocked full gf104 that was the same gflops and had more rops. the only market the gf100 stuff makes sense for is the benching community and they will not run an x2 they will run 4 cards given the choice so this card serves no purpose other than to prove that NV has no idea what they are doing or they think that they will have the same problem as ati when they made the high end mobile parts barts bassed even thought that was quicker and lower watt than the under clocked to end part.

if u look at the mobile parts on NV they do the same stupid crap as this and instead of using a gf104 they use a gf100 part and under clock and lock it to 384 shaders (althogh it looks like post launch some are saying that its a gf104 but the initial cards shown were square dies so gf100)

Time will tell, no use crying the sky is falling on day one, is it something to be concerned for, sure, is it a definitive wide spread product issue, too early to really say.

I mean I can't quantify how many burnt vrm's are out there from a handfull of online folks in the hundreds of thousands of units that are actually put into the market. If these issue where so widespread even on other products there wouldn't be any vendors that could afford to sell the product nor could nvidia cover excessive claims.

Is Nvidia being cheap on the vrm, I don't know, are people being too aggressive with what they expect, I don't know.

What I am fairly sure of is if there is an issue now that will potentially lead to excessive warranty claims it will be rectified in short order whether it is bios, driver, or hardware implemented.

The youtube video says the voltage was at 1.025 V when it blew

GPU Clock @ 772 Mhz
GPU VCore @ 1.025 V

Edit: Ok now I realised you were talking about the techpowerup article and not the quoted SweClockers.com link

I just wanted to remind you that several people have reported that setting 1.025V in software actually pushes about 1.1V to the GPUs as measured by a DMM.

I swear next time nvidia should just send out 50 cards to random pc enthusiasts via a lottery, instead of sending them to reviewers, and tell them to post their impressions of the STOCK card on a forum. I WISH i could drop $700 for one of these cards. If I got one for free I wouldn't be finding every flaw with it, I would be jumping up and down saying THANKS. It would be a different matter entirely if I was gaming and the card blew. life happens. That's what RMA and a lifetime/3 year warranty is for, it is not there so you can push a card to the breaking point and whine that nvidia makes a sucky card, and then take advantage of the system to get yourself a new one.

Hey nvidia if you are listening, send me a GTX590 so I can GPU render with it and post my impressions of what this card can do in capable hands.

Drives me nuts thinking about how the best, most power efficient GF 110's went into these 590's and people are wasting them by OCing when they don't know what they are doing. The 590 is clearly to any reasonable person a card that is already pushing the limit of what can be cost effectively engineered at this point in time, so why expect 30% OC on a card that is already pushed to the limit when you pull it out of the box.

And someone send some case fans to France, ffs, they seem to have run out.

ignorant might of been the first word to come to mind reading this.
Reviews are exactly that. To tell the good and the bad. IDK WHERE in the world you think that its ok for a company ANY company to produce a product that isn't reliable and get called out for it. Thats just a problem waiting to happen. How could you support a company that could possibly screw you over and who wants to rma a card? really spend another $20 in shipping wait 3 weeks to a year on some company's trying to get a card back
Your reasoning is why you aren't a reviewer nor would be getting a card for free. Nobody wants biased reviews, and yelling about how happy you are for getting a free card sounds like you'd praise it and ignore the faults of the card.
On top of that if you had $700 to spend on the card that you worked hard for..and it dies then ur cardless your telling me thats OK..and not just one out of a million or even a 1000. We are talking 10+ cards that i know of that have died so far..Thats just way too many and these are people running these cards for days..you really think this type of quality can be trusted to last year(s)...i wouldnt chance my hard earned cash on it.

This is driver problem. 267.52 has no OCP! With 267.71 everything is fine.

http://www.sweclockers.com/nyhet/137...boven-i-dramat

At default clocks and with NVIDIA's power limiter enabled

According to NVIDIA this should not happen. In their official reviewer driver (which I used), the NVIDIA Power limit is designed to be active for all applications, not only Furmark.

After talking to several other reviewers, this does not seem to be an isolated case, and many of them have killed their cards with similar testing, which is far from being an extreme test

I hope this was only a problem with some early card... time will tell... Now the problem can be related to.... the OCP... let say the card have try control the Powerdraw and some parts have don't like the work to do.
