GTX580: 1.025VID: 950/1900/2300: stock cooler: guaranteed?!?

[nolonger]

Hey guys,

My bday is coming up before the end of march and I think I'll gift my self a GTX580 ( coming from a GTX285 ) Altho my brand optios are extremely limited to whats locally available in my place but Im looking at something like Palit, Inno3d, EVGA and probably Asus/MSI.
Seems like a fairly decent speed upgrade from my GTX285, currently Im looking at the Palit model which shows a non reference dual fan cooling on their website, gotta confirm it with the retailer first.

I've back read a few pages and it seems that lower stock VID = higher possible clocks, I havent been able to narrow down the average overclock.. Would it be around 900-950core ?

I'd go with MSI brand if available. Next probably EVGA. 900-950 is pretty much guaranteed. A lower VID will help just as much as would on a CPU.

Guys with my Asus GTX580 I can't go past 900Mhz core. It always freeze with first 3DMark2011 test. Is it possible?

I tried @ 1.138V!

Damn, I found it is "fan" related. Setting it @85% let me to go last test (with freeze ).

Is my GTX580 damn bad or do I have a temp. problem?

This is the screenshot from NVIDIA Inspector:




I think I have found the reason. @1.05V as in the screenshot it goes @95°C after 5 min. of stress test.

So the question is: is the stock cooler so bad?

max fan? could be the stock cooler

every gtx580 stock cooler performs differently

try an aftermarket cooler or rma the card

up to you.. good luck

I can't RMA the card just cause in my middle tower it takes 95°C... the card runs perfectely. Just very hot.

middle tower.. you need better cooling or at least higher air flow

what i meant by "or rma the card" if after you try a better cooler temps are still high and cant get higher clocks rma it because the card runs too hot for the above^ voltage n clocks you barely budged the mem clock aswell

What case and custom cooler do you think I should get?

Anyway I am really convinced it is just a temp. problem cause when I start my PC in the morning I can easily bench @900Mhz core with decent voltage:

Good lord im stuck with either EVGA's GTX580-SC or MSI's OC edition which is extremely expensive.. I understand both cards are of stock reference design so its gonna be a coinflip on which will OC better

These are my temps. during a Battlefield Bad Company 2 session:

Can you get an Asus Direct CU 580? Not too expensive but should handle the volts better than a reference card.

Not available

EDIT:

Found a retailer that has it but its like $131 more expensive hahah

Got my Asus DirectCu II 580 today, with P0 Vid 1.025v. Too bad that these max voltage is 1.15v without mods, but that's enough for 990MHz core clock!

LOL isn't it strange that my stock GTX580 (Asus) can go @1,213V and DirectCu II just 1,15V?

That's was my first thought when is saw that.. i hope they realease mod bios for these soon! +0.4v hardmod doesnt sound very good without ln2!

Seems like this card built for cold run...Stock air maxed so far...

Very nice guy

Let's see what this can do with 1.213v.. updating!

That bios was very disappoint, couldn't even reach 990MHz 1.15v with that "cold slow bios".. and 1.213v 1000MHz was no go.
There must be some issues with that bios and DirectCu II pcb? Well, have to stick with stock bios until i can find working 1.213v bios..

I think you use the original BIOS is better than CSB BIOS

Have anyone tried to unlock DirectCu II 580's max voltage with nibitor (nvidia bioseditor)?

ASUS 580 BIOS non-1.213V?

[Asmola]

ASUS 580 BIOS non-1.213V?

If you mean Asus reference 580 bios, no i havent tested that. But i might give it a try..

What they were thinking when they limited these card's voltage to 1.15v??

Just try it
In my impressions , ASUS 580 BIOS is unlock the voltage

[Demo]

Btw, how much power does 2x 580's eat up in SLI ?

[Dumo]

2 CUII s/n1213 and 1212...

[Asmola]

Bios vmod with NiBiTor worked fine and now im able to use 1.213v on my DCII without losing card's stability.

That cold slow bios also dropped my card's P0 Vid to 1.000v, so it's not constant.. but now using original DCII bios with unlocked voltage.
