i can say that my evga 1.000vid , never saw 70 C* even with stock cooling, 950/960/965 1.100 > 85% fan, now that i've koolance'd my evga, can't have 1ghz ... as don markoni did :|
(btw, i'm wondering why isn't present yet a gtx 580 official/overclocking, or whatever official 3d, like 460/560/570 has )
Mines 1.082 VID, so it's not far off yours. Yet it does 920c | 1840s | 2250m on stock volts, and as I showed in my last post 950c | 1900s | 2250m totally game/bench stable @ 1.125vQuote:

I think core binning may not depend on VID but other properties too, and there is evidence of a MHz cap most can't push past regardless of VID/vGPU.
Mine only does 900Mhz Core (stock volts) and I dont know about the mem as I never bothered to OC them nor do I know how to test the mem for stability so it does not auto downclock. My max volts though is 1.150v
I had a 1.000 and a 1.038, neither would do over 880 at stock volts , nor over 930 maxed, even with asus bios mod. I have another one now that is supposed to do over 1000 so Im keen to give it a shot but I need to get the mcw80 fitted first.
:up:
Is there like a specific crysis or warhead benchmark loop that really stresses out the hardware that much ?
Benchmarks just don't stress the cards like gaming does. Furmark is just stupid, and works your PWM's and tests for max heat etc. Like I care how hot it's possible to get my card under those conditions. May as well put your tower in the oven and be like yo that's an awesome test my cards 200*C for 40 mins turning once while I cooked my dinner stable.
BFBC2 everything maxed 32MSAA is a good test, my personal fav is Atacama Desert as the the card has to render a lot of dust and smoke. Just play that for an hour or more and see how your card fares. Temps will climb slowly if you are on water and the system equilibrates to the CPU/VGA/Mobo heat output, and once it stabilizes thats when the stress test starts so to speak. If your OC is unstable (system too) that game will show it up pretty quickly.
I've only played the SP for BFBC2, is that a multiplayer map that I can load alone to testing/running around ?Quote:

asus tweak voltage cards has max 1.22v i've seen in some screens, i was wondering if i put that bios in my evga card if it will work or even edit ma bios ..... don't know if it works, and first of all if it's safe to do!Quote:

you should lc you card ;)
Unfortunately stock cooler. Benchable @about 940Mhz (no matter the voltage, it is just too hot).Quote:

I need to find my multimeter to confirm that but im pretty sure that's how it is..
Maxed 980MHz on Unigine Heaven. Atleast it's totally stable @ 950MHz 1.125v, and that's fast enough for 24/7..
So it seems high voltages are in most cases useless with these cards.Quote:

ye i agree :clap:Quote:

i've maxed 975mhz on unigine.. but is fine enough :rolleyes:
:up:
yes it seems so!Quote:

Alright, How about GDDR5 stability, I heard these things auto downclock if it goes to high.. would 2200Mhz on a GTX580 be like 100% attainable ?
EDIT:
Looks like ambush is not even able to maintain a constant 90% GPU usage, probably its my Q6600 @ 3.4Ghz thats being a bottleneck to the GPU.
EDIT2:
So today I was just stability testing on my GTX580 its been running at 900Mhz core for quite some time at stock VID of 1.088 and on my first run on heaven 2.5 I got a red colored lens flare rendering glitch, which I fails to repeat it self after i tried 10 more loops. Stability testing on videocard OC's are quite unsatisfying (haha!) using 1.1v is too much for me just to get 900Mhz core, maybe ill just dial down to 850Mhz core and undervolt my GPU.
I wonder how nvidia/evga came up to binning this chip at 1.088v, I mean if the chip can do 1.025v with 850Mhz core why is it binned at 1.088v
Your Q6600 is def bottlenecking the GPU. It doesn't nearly stress the gpu since you're bottlenecking hence theres no stability issue.Quote:

Went on my 980, GTX480, just simply incredible :)
