1.6v under water for benchmarks? safe?

post #1 of 6
Thread Starter 
i put it to 1.6-1.65v to get over 4ghz+ on my X4 630 to run 3dmark vantage, it actually passed (really nice score for my 630!) but temps got pretty high (still under 50c though, but i usually load around 40c) for my XSPC rasa water cooling

is this ok since im under 50c? i dont run 1.6v+ 24/7 but will it degrade the chip if i run benchmarks at 1.6v+ once in a while? then set it back to 1.4v 3.6ghz for 24/7?

I remember reading somewhere that the higher you overvolt the colder the TJMax is. However when I had my Phenom, I wasnt afraid of 1.6v. But 1.65v is another story. Something I wouldnt do without sub-ambient cooling.

even for <30 minutes to run a benchmark? so you're saying 1.6v+ and the temp limit is NOT the same anymore, but lower?

i ran a few benchmarks at 1.64v which surprisingly passed, you think it degraded my chip a bit or it's fine?

you CPU is worth >$40. just run 4Ghz or even higher for 6 months, once it degrades quite a bit
then it's time for an upgrade

Make sure the MAX temp doesn't exceed its safe max temp. Keep it under that, your fine for longevity wise.

Maybe it's an AMD thing but changing the voltage shouldn't change the TJmax. The TJmax is simply a temp barrier, that once hit, the CPU will either shut down or underclock severly to prevent damage to itself.
