[HWC][Nvidia] Nvidia's response to GTX 590's frying - Page 10

So what's the result? We have a single card that in its default configuration pulls GTX570 SLI numbers. Drag the clocks up to 732MHz and we have GPU throughput that's just behind GTX580 SLI.

Now, I agree that nVidia could have over-engineered the card, and left it deliberately down-clocked, knowing the kind of crowd the card is aimed at. However, if the end result they aimed for is a performance card with a QUIET cooling solution, that would determine the rest of the engineering decisions made around its design and implementation.

Aiming for a single card that would not hurt GTX580 SLI purchases might also have been a factor in the decisions they made. $700 vs $1000 is a big difference.

Who knows? Unless someone from nVidia comes on OCN and tells us the whole truth, we can sit here guessing until the cows come home.

And much quiet too. Fan at only 49% and it barely hits 81C on Furmark

What you failed to mention is that the power limiter is on.

Average overclocks in reviews are no were near that...

My rule is never play with voltage at stock fan speed. The guy at Pureoverclock says if you will touch the voltage set your fan to say 60%

Anyone that got the 6990 to anything higher than probably 940Mhz with voltage added had to set the fan very agressive or else it just downclocks.



???

The thread says Nvidia responds to 590s Frying.

Nvidia says don't go crazy on the voltage, especially on stock cooling.
You realize the problem is with vrms blowing and not frying the gpu cores right?

Most reviewers did not have anyway to adjust the voltage since only the Asus card comes with such utility.

Overclocking the GTX 590 -

Thetechreport - 690MHz overclock WITH higher voltage
PCperspective - 675Mhz overclock
Guru3D - 675Mhz overclock
TechpowerUp - 775Mhz overclock
Techspot - 670Mhz overclock
Overclock3D - 660Mhz overclock
Legit reviews - 690Mhz overclock

Average overclock is 690Mhz

If you discount the over then average Techpowerup overclock then the average drops down to 676Mhz.

Reference GTX 580 clock is 772Mhz

I though this card was an overclocking beast??

And as pointed out by Nvidia at the start of this thread, Overvolting can cause serious issues with the cards reliability.

The 6990 can take voltage all day every day with out the risk of components burning out.

Some websites have said the issue is isolated to the ForceWare 267.52 drivers, but this isn't true as we only tested on the FW 267.71 driver and ours did die as well when overclocking.
Ah, the smell of a burnt VRM.

So, there's a few things to note :-

- Do Not increase voltage above 1.05v, even if the option is there to go higher. We've only heard as high as 1.000v has been tested.

- Ideally NVIDIA would prefer you don't increase voltage at all on reference cooling, but have recommended no higher than .963v.

- This doesn't reflect all NVIDIA GTX 590 products, nor the quality. Throwing almost +300mv on any card with air cooling will more than likely compromise the card's health.

- The issue doesn't seem to be related to any particular driver release.

- Do Not increase voltage above 1.05v, even if the option is there to go higher. We've only heard as high as 1.000v has been tested.
You cant fix hardware inadequacies with software.
