Quick E8400 voltage question.. Too much?

[maxwolfie]

Hey guys,

I'm currently Orthos'ing my CPU at 4.2ghz, 1.49v in BIOS, however I get massive vdrop & vdroop

Idle in CPU-z is 1.456v
Load in CPU-z is 1.424v

Any lower at all and my 4.2ghz overclock becomes unstable in Orthos only after an hour. So far, with the above settings, it's 11 hours Orthos stable.

I have decent air cooling, a Zalman, with a lapped IHS on the E8400. Reported temps in CoreTemp 0.96.1 are 72c/70c. Although I've read from multiple sources that the temp sensors in these things tell lies quite often.


Is this overclock "safe" for 24/7 use? I'm a little worried about the slightly-high vcore
