GTX 590 bios is good, no changes

Written by Fuad Abazovic

Nvidia officially responds
You are aware at least one Nvidia card has burnt so far and, as reported earlier the cards that died prior to launch come from Asus. When we put two and two together it's pretty much clear that Asus must have done something to the cards and we decided to look into it. 

Asking around we learned that the weird clock of 612 MHz was not the only thing the company changed. Namely, they changed the bios and let people use 1.2V (default is 0.9) which is way to much for the card. It ultimately results in TDP going up to 550W.  As you can imagine, this is way to much for the card to handle and the power parts give up, eg. burn.

Nvidia wasn't tightlipped as the company got back to us with a following statement:

"NVIDIA's reference GTX 590 VBIOS on the production boards has not changed, and we have not provided a new VBIOS to AICs or end users for GTX 590.  The original GTX 590 VBIOS that NVIDIA shipped is good for customers to use and we stand fully behind the reliability of the hardware with that VBIOS.

We did hear of one AIC partner who issued a custom VBIOS update specific to their board and we are checking in with them on the details of this."

We will hear more tomorrow but the new driver doesn’t let the card to draw insane amounts of power such as 550W, as this will clearly kill any possible card we know of. New driver prevents it despite the bios tweaks.

So far out card didn’t catch fire, and it works well even overclocked. We are not aware of any issue with highest clocked TGT cards either. Let's see what tomorrow brings."

Nothing nVidia said contradicts your earlier article:

Quote:
Now Nvidia says that its engineering team just completed work on a BIOS that is intended to prevent future GTX590 explosions. However there is no word when the fix will come out.


Spin, spin, spin!

VRMs insufficient. Same issue as the GTX 570.

http://www.overclock.net/nvidia/929152-have-you-killed-570-a.html

Honestly, there's no surprsie to this. The GTX 590 has a total of 12 VRM's, that's 6 per GPU. If we quantify that, you're assigning 4 to the main GPU, 1 to the memory controller, 1 (dual phase) to the RAMs. This is pretty inadequate since full GTX 580's are usually complemented with 6+2 power phases, here in the 590, Nvidia gave only 4+2. It's no surprise why the card fails under such treatment.

VRM insufficiencies affect Motherboards as well.

GTX 590? Wait until the Asus, MSI or Gainward/Palit non-reference, then we'd be talking power.

Funny that company like Asus did not see that they may have problems with over voting. Do they not test these cards in the lab. I guess not. They just rush them in to production.

"GTX 590 bios is good, no changes"

Yeah its great...

"Our best card yet"

BOOOOOM!

As warrior always says nvidia has the most superb drivers, something AMD has to learn off...nvidiots and they sucking fry pans

I wander what happened to Warrior.. He hasn't posted for days.. Maybe the epic failure of Nvidia was to much for him?

What we're the chances both dual cards would be disappointing this gen! :-* 6790 looks more exiciting.

ASUS must be really mad with nVIDIA right now.

The problem isn't that they overvolted the board, it's that the board has no protection? Where's your consumption control? Where are the VRM necessary?

Don't go blaming your partner nVIDIA!

Good. ASUS successfully burnt: Check!
Only thing is, the one that bit it over at Overclockers.uk was a ZOTAC ;-) (At this point I'll remind you that it was running at stock, with no overclock). So how did ZOTAC sabotage the 590 Fuad ? Since clearly ASUS is to blame for an Nvidia reference card blowing up..... :-*

What the hell did EVGA do also!!! the Scoundrels!!!
