955 3.8GHz, how does this look? - Page 2

post #11 of 16
Thread Starter 
ok now im confused. i set everything back to stock to test the ram timings. and CoreTemp is telling me my voltage is set to 1.4V and CPU-Z is fluctuating between 1.375 and 1.381.

i thought stock was 1.35V ?

i think it depends on the board or chip. some are 1.35v and others are 1.4v. my stock is 1.4 but idk why because no 955 needs that much on stock.

IMO 3.8Ghz and 4Ghz are hardly different real world wise.
Just stay on 3.8Ghz, bump up the NB and see how low you can get the voltage on the CPU
For me I have to use 1.46v for 4Ghz or 1.32v for 3.8Ghz, which is much cooler

after changing the volts to 1.35, there have been no problems in prime95. so i think i'll try and get back to my original settings and work my way from there. thanks guys =D

what voltage have you set yours to to get 3.82GHz?

And does overclocking really not affect lifetime?

Yea I changed mine to 1.35 while I was running on stock. I'm currently OCing my 955. I have it stable at 3.82 w/ 1.40v on load.

The only thing that will really degrade chips faster is more voltage but as long as you don't push crazy volts through it, it won't make much of a difference.

Great, thanks for your help =]

Currently testing 215 x 17.5 at 1.4375v . Downclocked ram to 1433 though,

EDIT: tried going to 220 x 17.5 but had to raise voltage to 1.4625v and im slightly uncomfortable with high voltages even though temps never went above 48C. i think i will go back 200x19 and raise the CPU/NB to 2800MHz
