Safe 12V Rails

post #1 of 10
Thread Starter 
So right now my 12V Rail is running at almost 13V. Is this safe? I underclocked and undervolted my RAM, but that doesn't seem to help much. I really hope my $100 PSU isn't going to be the thing to hold back my OC...

Did you measure it with a multi-meter or by software? You really cant trust software monitoring..

Oh, I was using Speedfan, don't have a multimeter. But, I am still getting crashes when running CPU Burn In. My CPU voltage is 1.47, but the temps don't get high before it crashes. Any ideas?

Is it OC'd..If it is you might need to bump up v-core a little bit...If not it could be any number of things, you'll just have to go through it a component at a time and see.

Well now it's passing CPU Burn In, Idle Temp 35, Load Temp 45, pretty high voltage on the CPU (don't remember exactly) at 2.6 GHz.

Shooting for 2.8 by night's end. Wish me luck

Just on a molex, yellow is 12V red 5V, just touch either the yellow or red with your red probe and touch your black probe to either of the 2 center black wires..

To test with a multimeter... brb with more
Check pg 34 for the pinouts, you can use a SATA power cable for all three voltages or the 4 pin for 2 of them.
Entend the cable out the side of the case and keep it closed as best as posible.
Best to load up the PC well to heat things up.
