Now I know for my card to gain stability for overclocking I need to unlock PWM clocktuner, PLL, GPU & Memory switches.... OCP unlocker set to default setting for safety just like you said biggrin.gif
But again the weird is I don't see any added voltage at GPU, memory and PLL on MSI Afterburner... I think I need Afterburner Extreme to do that but I don't want to do it biggrin.gif
TFIII fans are too loud at 80%, not mention at 100% biggrin.gif
Note : Are you using MSI Afterburner 2.3.0, Sashimi? It shows GPU temp, memory temp & VRM temp on my card smile.gif I thought only Lightning Extreme has these features, right? Mine is Lightning not Lightning Extreme.
Also my full load voltage at stock clock is 1.006v smile.gif just like yours, mate.

I'm using the latest MSI afterburner and I have 3 voltages which i can tweak: Core, Memory and AUX. I'm not sure if they're available for the normal lightning though. Memory clock honestly don't do much so you aren't missing out on anything even if you haven't got separate voltage for it. I don't even know what the AUX voltage is for. I didn't do any hard switch tweaking so these options all pretty much just came out of the box.

In the monitoring screen I also have separate core, memory and VRM temps. I think all cards have these separate.

Yup neither do I, mate. But I heard that AUX voltage is for added extra voltage to the card via PCIE-line on mobo and not from direct PSU 2x8pin.
If you see on >>MSI Lightning Series<< then you will find that my card doesn't has these 3 sensor on AB graph, it should only has GPU temp sensor... but Lightning Extreme do have these 3 sensor smile.gif

Found the issue. Its a common thing w/ 580s. Looks like Crysis 2 (the main game crashing) requires a few extra notches of volts for dx11. The driver switch was probably happening because of the crashing and windows updates. I've since reformatted and I'm on my 2nd ssd (trying fix the issue) since my first one is acting up. Quad is a pita so its understandable things like this may happen. So far I'm still running 301.xx I just have to figure out my power setup for my home to cope with the tremendous amount power used in Surround and running Crysis 2 maxed (w/ vsync).

edit: I have an AB profile for stock clocks but with 1050Mv just for Crysis 2.

I installed the windows update, didn't work, installed the latest nvidia driver (think it was 306) and it worked again, and the windows update disappeared too. so it's all good now.

Crysis 2 is the most stressful program I have encountered on my GPU. Passed 12 hrs heaven but failed Crysis 2 in 4 hrs...If you truly wish to test for stability, turn off v-sync that make sure it uses 100% of your GPU all the time...that'll push your card to the absolute limit!!

I just uninstalled 310.61 BETA driver because it was not stable, first it was stable enough but after afew days or a week I saw my GPU score abit lower than usual and starting to crash on game, black screen and freeze at stock clock. Now I'm running with 306.97 WHQL driver direct from MSI website biggrin.gif works normal now thumb.gif
