Try and run heaven on loop for about 45 minutes and watch for colored flashes of light as a sign of instability, they will look like glare from the sun or other lighting effects gone wrong and they will appear at random times and be all sorts of colors.

Yeah sorry, I guess I just wasn't paying enough attention before but they are there (the coloured flashes). What temperatures are too high for this card? If I go further with the voltage it will undoubtedly get warmer unless I blast the fans...

Yes, of course! I want to protect my baby not send lightning through her veins... is 1.1v too high? I am currently testing 1.05v.

I wouldn't be concerned with up to 1.075v on your card and possibly 1.1v but unfortunately your card does not have any VRM heatsinks so those are the part that will get too hot before the core would and we don't know what temps those are running at. They core is specified up to 97C by Nvidia but I would want to keep it below 85C.

Nah im sure the cards an handle 1.1v. My old 5770 can handle 1.3 but its a different card.

Are you sure 1.05 v is enough...? -.- And yes, though random color flashes are artifacts. If i ignore the artifact on my card, i can get it to 1ghz. It wont crash at 1ghz for me, just artifact like a mofo

if he doesnt overclock the vrams then he should be baby blue fine and not worry about the temps on his vrams

VRM not VRAM, I'm talking about the voltage regulation modules which get hotter with increased voltage and have no heatsink on his card. The fact you've run whatever voltage on a completely different card should have zero weight on what he should be running on his card.

Have you guys noticed that in GPU-Z the CUDA and Compute5.0 blocks not checked off on the GTX 560 ti 448?

Is the lack of VRM heatsinks an MSI flaw or is it a problem with the other 448s as well?

Oh you have the MSI TFIII PE/OC? I thought you had the EVGA Classy for some reason. The MSI TFIII PE does have a VRM heatsink so you'd be fine up to 1.1 or 1.125 IMO.
