Undervolting 5K BE

post #1 of 6
Thread Starter 
Since the hot summer weather is upon me(South GA), and my PC temps have decided to skyrocket, I was thinking about underclocking and undervolting my CPU... I was thinking of maybe trying for 2Ghz(250x8), but I wanna know if its safe to run sub-stock voltages. I have heard rumors of this not being good for chips, and causing headaches when going back to OC. Im just looking for a bit of advice and guidance before heading out & trying this. Thanks folks!

Yes that's perfectly acceptable. As a matter of fact, I undervolt my own personal chip 24/7. Opteron 165 @ 2.8GHz with 1.25v. It'll run just fine, the voltage just adjusts temperatures essentially, so the less voltage you can run, the better temperatures you will see.

I run mine with a mild overclock (stock is 1.9ghz, OC is 2.4ghz) and undervolted (1.35v stock, 1.3v right now) with no issues.
Undervolted and stock speeds should be no problem at all.

It's not like running a car without oil. If a processor doesn't have enough voltage it just won't run right; you don't have to worry about wrecking it by undervolting.

The Brisbane should do some incredibly low voltage at 2 Ghz.

Why dont you just enable cool n quiet if you intent to underclock and undervolt? it doe sit all but on auto.. saves power too...

I though about that too, but I am just gonna undervolt it. I dont care to hear my fan throttling up & down when I go to load up the CPU.
