How safe is this gtx 560ti overclock?

post #1 of 14
Thread Starter 
I have MSI GTX560ti twin frozer II overclocked to 985MHz core and 2200MHz on memory with 1.087V. Temps raised to the 67C while benching in heaven benchmark with automatic fan speed. More testing needs to be done to really say is it stable.

But how safe is 1.087 voltage?
I´ve read that there is lack of cooling in the cards power supply? ???VRM:s???
Can I check how hot the vrm:s are in the card?
How hard is to apply these vrm heatsinks?

I think my case cooling is fine 3 intake fans and 2 exhaust fans in Antec 300 and one of the fans is blowing directly against the gpu on the side.

I can do 945MHz on stock voltage but i like MHz:s.

I'm stable on my Palit 2gb 560 ti at 975/1950/2200 with 1.050v. That's with running furmark for over an hour and all benchmarks. My cooling however is no where near as good as your twin frozer II. It tops out at about 90* C in furmark with auto.

You're fine. 67C is nothing to worry about.

Thanks for every one who already helped. I tried to go little further @1000MHz core with 1.125 voltage I didn`t saw temps breaking 70C. Screen went black and said no signal and gpu fans went max rpm I think. After that I needed to turn off and on my computer.

Is this normal way of showing that overclock isn`t stable?
Or is it cards way to prevent damage?
Has it something to do with heat?

Both of those, you are good on temps till you hit ~95C+

Ok. So you are running 1.15V. How high is your card overclocked?
How long have you kept that overclock?
Where do you keep your fan speed?
What kind of temps are you getting?
