Is the highest I could get my card to go. had to run 1.1v aswell. but its now stable 24/7 I tested occt for hours with no errors.

I see a lot of people posting way higher core but I dunno if I just have a picky chip that doesn't like to be oc'd or is everyone running those numbers just to run a 1-2 min bench tool.

I find it hard to believe that they can run 900+ core 2100+ mem on 1.1v all day with no errors on occt.

At stock clock my card does well, i ran tests and compared to other gtx 570 / 580 and ait 6970 and 6950 cards with people in my games to see if i was on point which i was. So i know more overclocks are good as well. not huge numbers but a good amount none the less.

Just curious about the rest of you guys with these very high overclocks and how stable they are and does that mean my card just doesn't like to go higher.

its a evga non oc'd model gtx 570.

my comp specs are

i5 760 oc'd to 4.2gig
4 gig on corsair domi
cm gx 750 psu
asus p7p55d mobo

just wanted some feedback.

thanks.

and yes i am a new oc'er as of the past couple months.

My Palit GTX 570 Sonic does over 950MHz at 1.1v and I had the memory as high as 2200MHz. My everyday settings are 925MHz core and 2100MHz memory. This is a factory-overclocked model with cherry-picked components though. And yes, those settings are stable in games/benchmarks and even in FurMark.

Is it supposed to be just a static scene with no movement except for the numbers on the top left in GPU : OCCT mode? It seems to be loading the GPU somewhat but it's not making it ramp up to full speed. The reason I ask is because in Power Supply mode the scene moves. Maybe I need to reboot or something.

After I rebooted and started OCCT again, it loaded the GPU like it was supposed to.

It took me a while to find the speed where it wasn't producing errors, and I had to back it down quite a bit. At 1.1v I finally settled on 865MHz core speed, and I didn't have to change the memory so it's still at 2100.

I can increase the voltage to 1.125v, so I'm going to see if I can get higher core speed with no errors at that voltage.

Palit GTX 570 Sonic -- Defaults: 750MHz core @ 1.025v, 975MHz memory (Afterburner shows 1950MHz, actual effective speed is 3900MHz).
Current settings: 860MHz core @ 1.100v, 1000MHz memory (Afterburner shows 2000MHz, actual effective speed is 4000MHz).
Custom fan profile runs the fans at 70% speed until GPU temp hits 60ºC, then rapidly increases to 95% at 65ºC and above.

I tried going higher than 1.100v GPU voltage, but the speed increase wasn't worth the temp increase.

Oh lol 8000 MHz effective would be insane.
