[GTX 590] Flashing & Overclocking Thread - Page 53

post #521 of 721
yes it is possible i crossflashed my 37 with 42 bios and it worked fine now i have both card with same bios 42 im stable at 715mhz first card im using 0.963v but the second requires 0.988 to get pass 700mhz on 3d mark2011.
ps: ihave evga hydro cooper temp are around 38 39degres on full load i can push the voltage more till 1.063v then i coud reach 800mhz but the pdl and ocp kicks in and the card start to sttutter and gets fps drops so 0.988v its the limit to get stable frame rate.

I've just tested 42 one at 700 MHz - it is failing, let's go for Gigabyte now with 37 bios to see if it's stable.

If it will be clear that 42 is failing - would you like to change bios to 988mV for me again? Of course if you have enough time to do it.

Gigabyte one with 37 bios just passed 3dmark11 with 700 MHz at core.

Amazing.

I would be glad if you could change the 42 bios for 988mV vcore so I can push it a little more tongue.gif

there you go 70.10.42.00.02 bios with 0.988v be carful with temps i highly recommand to go for water cooling you can use 100 pcent fan it will work fine but its too much noise for everyday use.

Yay, barely passed 3dmark11 at 700MHz biggrin.gif

Good enough I guess smile.gif Thanks.

Cards are only flashed for benchmarking purpose - I will flash them back to original stage for normal use.

i saw your 3d mark score 5000ghz on a 3930k lol what kind of vcore did u use on cpu?
post #527 of 721
1,44 Vcore was just fine to make it stable at anything (it's water cooled using Corsair H100), haven't tested lower voltages to find the lower point of stability.
post #528 of 721
nice chip my 3930k needs 1.51 v to get 5ghz stable :/

Now I'm reconsidering buying into SB-E! Too close to IvyBridge, though.

Is there a vBIOS that can take my EVGA GTX590's up to 1.000V absolute max. and still be kept in check using MSI AfterBurner? I know that there's a sweet spot between my 0.9380V max. and 1.000V. Probably just a 0.0500V increase is all I need for stability.

ATM, I've started black-screening in the 1st test of 3DMark Vantage at stock settings. Every single restart I lose the Nvidia Control Panel. It's there running according to the Task Manager, but will not appear when I click on it in the context menu. Only a full driver uninstall/reinstall will bring it back. I did just that 6 times last weekend and twice already today.

I know that this isn't the proper venue to mention the NCP but I've tried umpteen different Forums and more threads than I can even remember for even a possible fix, to no avail.

I can't even confirm that PhysX is working through the NCP and that only the 3rd Core of a Quad-Sli is actually working during benchmarks.

Is the latest version of GPU-Z's (0.5.9) ASIC Quality tester worth anything? One cards cores stay around 72% and the 2nd card reads about 82%. Quite a bit of disparity there.

If I flash 37 one with 42 bios will it need 988mV as well to make it stable? Since it's working fine at 963mV with 37.
As far as I remember you said I need 42 bios to get past 963mV.

I think I need more voltage, missing 800 points in 3dmark11...

Is there possibility to disable PLD? I would be willing to take the risk since I've noticed the second card is throttling while benchmarking when the first one is not (tested separately).
