New Adventure: Undervolting

post #1 of 15
Thread Starter 
I have now decided, duie to all of the hot weather, I will undervolt, especially since I will be Folding 24/7 now. Right now, I have it at 1.9 GHz (stock) at .95V.

However, my roommate brought up a good point. Would this cause any damage? My initial thought was no, but he said it would be the same thing as a brown out for your CPU.

Any issues you guys forsee? I'm going to get as low of a voltage as I can at stock speeds, and see if I can OC it at all below 1V if possible. It's just too dang HOT!

I know what you mean. 2.13GHz with 0.9750vcore right now.

I don't know if this could cause damage, but I am 100% stable. Nothing freezes, crashes or fails.

I kinda figured that if anything was gonna get damaged, it just wouldn't boot. I mean, if you OC and you need more volts, it just reboots (or fails to boot). Then you put in mroe voltage. Shouldn't it be the same with slow speeds and lower voltages?

It's impossible to cause damage with low voltage. The worst that could happen is it would be unstable.

Brownouts cause problems in electronics for totally different reasons and are basically completely unrelated to CPU's.

The more you under volt the more it should last in fact. Everything i know says we should all keep the voltage on our CPU as low as possible so we have less wear and tear on the CPU. Of course i wouldn't put money to it I'm no expert.

You don't have to undervolt all of the time

edit: Just saw you would be folding, so I guess it wouldn't work for you. 1.9GHz at 0.95v is pretty impressive though, I guess Brisbane's undervolt better? I have a really good chip and the best I can get it at ~2GHz is 1.05v

Why? If there's a power surge.... your surge protector would be hit first... then your PSU... then your VRMs... and then your CPU.

Undervolting would actually make it safer against power surges, not less.

what if your not using a surge protector?
I'm sure not.
I'm lucky that my cpu didn't get fried when a lightning bolt hit the transformer that controls our town's electricity
