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

[Kimofil]

Anyone tested GTX580 SLI\tri-sli with new Heaven 2.5 all max fullHD?

[donmarkoni]

How can I check if my OCP is turned on or ff?

There is no tool for it, as it is always turned on, unless using modified BIOS.

If you use GPU-Z to turn it off, know that it's turned back on again after every restart.

You can see the difference in Furmark score with and without OPC, and also you can see higher power draw if you have some kind of power meter.

Does it affect or reduce performance in games or other benchmarks life Heaven v2.5 ?

Not on air/water, but I can't tell for DICE/LN2, as I didn't try.

Anyway, I disable it while benching, just to be sure.

Any specific test to loop under Vantage?

Loop the Graphics tests for 1 pass and then go on to gaming I'd say. If you really want to, do 3 passes.

The card came today, just installed it and did an 06 run. It has a high vid, 1.03v, needs 1.138 for 975mhz to run 06. Guess it wont be a great clocker, but it does run very cool. I will have to flash to a modded bios to go much higher. I think I can score just as well with my gtx470so card with the cpu at the same frequency, 4500mhz.

[Dumo]

My CUII with vid 1.00 won't go past 960ish core no matter what gpuV I jolted it...this probly the high leakage one that will do best with cold/LN2

The other one with vid 1.03 clocked to 990ish core easy with 1.15V.

Thats good to hear, I thought I got a dud at first when I saw the vid.

Shocking that your 1.00vid wont do better though, I would have guessed that would be a real cherry.


Not the best 2600k, needs a lot of vcore for 5.2ghz to pass the cpu test in 06.

03 at same settings.

[Demo]

Where can I find a reference as to where to get the voltage readout points on the card as well as the valid vGPU VID steps..

On and btw when undervolting I also need to keep an eye for artifacts right just like regular overclocking ?

EDIT:

Did a quick test with 900Mhz score at 1.150v and it gives me the flashing star like lense flares on GT1 in vantage.. meaning no 900Mhz core for me.. sucks!

Same points as the 480 for vGPU reading. Not sure on vMem. Known vGPU steps for me are: 1v, 1.025v, 1.038v and 1.05v.

You should also keep an eye on artifacts as they will occur if the voltage is too low.

I seem to be getting graphical glitches even at stock speeds with vantage GT1, Im pretty sure this did not happen with my old GTX285.. lense flare like glitches on the seams of that structure on the top right portion when you see the "ION" beverage logo on the screen and an a few ran and also some random patches of black blocks..
I dont have my GTX285 with me now to test again but I do have a GTX460, either my Silverstone Zues 750Watts is not giving enough power or my GPU is defective which is sad!

EDIT:

Happens with preset set to high and extreme, performance preset is glitch free.. gonna install the 460 and see if this also happens..

I was able to run about 5 loops of heaven 2.5 with extreme tes and 8x aa yesterday with out any visible graphical glitches!

EDIT2:

Unsintalled the driver and reinstalled it again with the GTX460-OC, same lense flare glitches happen but I noticed near the end when that craft flies the black square patch is smaller on the GTX460..

I dunno if this is a rendering glitch on vantage or the driver or my PSU or both cards are bonkers!

EDIT3:

Watched a couple of vids from trubritar at youtube and it seems to be also glitching on his own vids.

This might just be a vantage rendering glitch and nothing to be alarmed.

Nice score!

Cant figure out why I score higher with a 470 in 3dm05 vs this 580. Was able to hit 49,400's with a GTX470 at 890ish mhz, same cpu clocked at 5400mhz.
This is what I get with the 580. Maybe I need a fresh install.

Damn score , you get a very nice card

[aussie-revhead]

You guys are so lucky, neither of my two 580s will bench even at 940 with volts maxed and stock coolers. One is 1.038 vid and the other 1.000. Im going to put water on one and sell the other but I havent decided which to do which to yet ....

My 2nd. CUII with base V @ 1.03

[Demo]

2 loops with heaven at max settings 1680x1050, voltage at 1.088 fan peaked at 76% while temps at 89c, ambient temp in this very hot summer afternoon is 34c and this is with 850Mhz core only [sad]

Nice job!

You got a very nice card, 1008mhz core .

Also a big thanks for the help with getting my score up to par.

Ill keep tweaking it and see if it will reach 50k.

Second screen was a run with the Gigabyte gtx470. Maybe this 2500k cant push the 580 enough to get the score I was hoping for.

[donmarkoni]

Did this 10 days ago, but forgot to post, been busy with my new used car.

Changed drivers, new RAM, 5/10MHz higher GPU core/shaders clock, ~90MHz higher CPU clock and I got 300 points more!

P7916 --- GTX580@1030/2400 --- 980X@4610 --- Sector 5 2250@2000/7-7-7-20-1T --- R3E --- donmarkoni

Nice benching guys, im going to try those "old" test's also. My target is 1GHz core on 03!

[vern]

Nice guy

[Asmola]

3DMark 2001 1GHz 1.213v is easy, but 03 wont run that high with this ambient temp (26*c), max is ~995MHz!

Recently , GF110 chips is damn strong

[Demo]

undervolted my card from 1.088 down to 1.025 and using 850Mhz core, seems to be stable in 3DM11 and a couple of games.. cant really think of a good game to stress this card out properly aside from looping crysis runs.

EDIT:

At stock speeds/volts I seem to be getting a consistent rendering glitch or an artifact at a certain portion of Heaven 2.5, I've attached a video taken from my mobilephone camera.
