^ Asus did 5Mhz.

why is it 30%?
default is 0.98 and he went for 1.2v, hows that 30%?

default is not fixed, it depends on the board. some are closer to 0.90.

nvidia recommends 25mv increase here: http://nvidia.custhelp.com/cgi-bin/n...p?p_faqid=2947

which, if my math is right, means going from 0.90 to.... 0.925. there is not much room to work with here. thanks to some of these reviewers, we now know 1.2v is completely crazy.

but overclockers dont get to complain about frying their hardware. sorry. this is a rule of the road. a hazard of the job.

how so, if the pwm or a circuit burns then its not the overclockers fault if its an overclocking part

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.

[BababooeyHTJ]

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.

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

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)

on the breaking cards, people are getting dead MBs from to much pci-e draw and dead pwms and traces without overvolting and even at stock. if u cannot deliver stock clocks or an overclock up to the max that your software lets it do without changing the voltage and it dies on an overclocking part there is something wrong.

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.

Ok, how many people roughly, how many mb's, what are we talking 5, 10, 100, 1000, 1000000.

I'm not trying to say there isn't any problems, every product produced is pretty much destined to fail at some point but I simply don't see these mass failures for seemingly little to no reason.

there was like what 50-100 max sent out for testing and ive seen 2 youtubes of burning 24pins and heard that cards were dieing without over volting. i would give u that the cards dieing could be a fluke but there is no reason that any single card should ever cause 24pin burn

[Callsign_Vega]

All of this multi-GPU/single slot stuff is nonsense. I would never buy a 6990 nor a 590. If you want multi-gpu, just get multiple single cards and a proper motherboard to support them. It works out better in every way.

check my sig, there's an example.

[Vardant]

Going on what you've seen today, would you overclock a 590 aggressively? No you wouldn't. Can you imagine how pissed you'd be if you did, and killed it with what isn't exactly suicidal volts?

Except 1.2V is suicidal.
GTX 570 can die with 1.1V or more, hell even GTX 580/480 can be killed with 1.15V.

[Lanek]

And i have make run mine 5870's with 1.4V+ ( MSIA mod ) for hours under water for bench.... and it's far of the highest i have use...

anyway.

Here's the word of MSI in their features description of the GTX590 ..

Overvoltage Function of GPU
- Support overvoltage function of GPU to boost 38% performance up.
- GPU clock is overclocked from 607 MHz to 840 MHz.

All Solid Capacitor
- 10 years ultra long lifetime (under full load).
- Lower temperature and higher efficiency.
- Aluminum core without explosion.
MSI Afterburner overclocking utility
- Support Over Voltage function of GPU.
- Support advanced fan speed control.
- Support burn-in stability test

We are ok, overclocking is overclocking too much voltage is too much, but please. going from 0.9x to 1.05V and got some pieces who burn, is absolutely not normal... We have for most here OC our gpu's beyond the limit, it's really rarefull you get something like that, in general, you OC too much with tooo much temps, and a deffective Ram chips die....
I don't mean there's a global problem, maybe a deffective parts on some cards, it's not the first time we see something like that... But if i understand well some 570 have got the same problem, if this is right, why the hell use some parts who are subject of it on the high end cards, and specially a card like that.

[STEvil]

570's burn up at even stock.

This is what happens when you start cheaping out on VRM components to avoid powering the capabilities you've created.

Booom
I am just surprised on the price not bad..

I believe so Asus DirectCU or non reference cards don't get this prob.. so the way to go ?

Le 112 °C n'est pas devant un GPU mais sur l'étage d'alimentation qui chauffe plus que les GPUs. A l'arrière des GPUs j'ai 80 °C pour celui de gauche et 84 °C pour celui de droite

112 ° C is not a GPU, but the power stage that heats more than the GPU. At the back of my GPU 80 ° C for the left and 84 ° C for the right one

Congrats on sinking that low to quote a card from 3 generations ago!

That was AMD's first time using digital VRM (Volterra I think), and the card did pop and die if you actually used Furmark with older drivers. And guess what? Since the 5 series every GPU they made quotes board power truthfully, has proper cooling on every component on the board and hasn't been deemed loud (exc 6990).

Now that I've retorted your digression, why don't we get back to both the insufficient power regulation (for OC) and insufficient cooling for the VRMs then?

All I see is one card unusable @stock (HD 6990, even louder than 2 GTX 480 in SLi) and another one (GTX 590, cool noise and approx. same temps than HD6990) that is usable @stock.
With proper drivers and soft voltage modding, the card oc quite well.
But, you're certainly right, power regulation seems insufficient for massive OC.

Anyway, Damien take another thermal shoot, more precise :

....i might be slightly confused, but ur saying the 6990 is unusable at stock and the 590 is usable at stock...when the only cards to die are the 590s..and we're talking about in days of usage...me personally i thought this card would be very nice however after seeing this i wouldn't buy one at all cause who knows how the long term would be even at stock..Cheap quality for such an expensive part...

nVidia screw with their OCP software solution, but with proper driver version things seems okay. Waiting for more feedbacks and not jump the gun regarding OC though ...

so what makes the 6990 unusable ? it being loud....???
and some have reported ruined cards with the "proper" drivers
and like said this is people owning the cards for DAYS..imagine months/years even at stock..id be worried to say the least.

either way id say a card thats loud is slightly more usable then a card that...well doesnt work.
