Hi guys, wonder is it anything wrong to undervoltage, example, i am using AMD64 3800x2 default voltage is 1.4v but i ran at 1.325v, but when i oc to 2.6ghz i have to raise to 1.45v, for me i think its to high. any comment from sifu. TQ

wow..man..3.25v! only for 2.6 GHz?...hehe...with this kind of vcore u can reach almost 4 Ghz with good cooling system [maybe NO2], btw wat is ur cooling system?

Brother did you read my post properly, i mean underclock my voltage to 1.35v instead of default at 1.4v

sorry, i didnt notice that.. ..wat about ur CPU temperature?

It quiet low at 29 idle n 38 running 2x prime 95, anyway, any sifu can answer my question, whether is it adviseable to undervoltage .TQ

there no problem undervolting, as long it'll pass prime minimum of 6-8hrs
if not, some of heavy cpu dependant apps will fail (prime/folding etc)

i may be able to run photoshop, notmal surfing, bT, musics etc at 2.4ghz 1.45v
but i cant prime stable n fold unless i use 1.52v

Thanks for the info, anyway i did prime for more than 8 hours for that voltage, just curious whether is it wrong to do that.

well, if its stable, then theres no problem
but make sure prime cpu+ram (Blend mode) coz sometimes the memory controller is the culprit for failures if u only do small fft's

Normally, when i do prime 95 i use blend, that mean a lot of ram test.
