Above 1.4v safe for 24/7 use?

post #1 of 7
Thread Starter 
Hi, i recently bought an h80 cooler, and I am trying to get my cpu stable at 4.4 ghz for 24/7 use, I have tried going to 1.4 volts but the processor crashes in prime 95 after a couple of hours. I think I am close to getting it stable I just need to know if going above 1.4 is going to kill my cpu.
thanks.

I wouldn't go much above 1.4 volts. Many believe that 1.4-1.45 is the max safe 24/7 voltage before seeing any major CPU degradation.

OK Assuming this is for your i5 760, non sandy bridge CPU...

There were some issues with Foxconn sockets burning pins when pushed past 1.4V, I'm not usre if it was just a batch or is still occurring today.. was caused by not all pins mating between CPU and mobo socket. So just check what socket your mobo has, if it's Lotes then you good.

thanks.
1.45v max.

I run 1.45v on my cpu 24/7. As long as the temps are below 85'C LinX/Prime load, then you are good with that voltage.

Page 65 of the Data sheet has the "absolute maximum" listed as 1.40v

http://download.intel.com/design/pro...hts/322164.pdf





Each gen cpu is different. The first gen i7's 900's are rated at 1.55v, the i5 700 & i7 800's are 1.40v
