I ran Orthos for a time....

a time?

Needs 8 hours+ to gurantee stability.

I'm currently @ 1.38v in bios testing @ 4Ghz (anything below fails prime after 2 min), the dorop is pretty high on the P5B dlx and I haven't got round to pencil modding it so that is about 1.35v load.

EDIT : Got a PI 1M of 11.6s with 4Ghz :D.

Seems my CPU clocking/volts are exactly the same as Deluxe1's from my testing tonight. Wouldn't surprise me since we both have the same stepping :)

Should be able to give it a full 8hr run tommorow.
 
JUst got my E8400 installed. Currently testing 3.6Ghz with 1.2v

I don't know if it's the bios or it is the actual idle temp but I seem to have an idle temp of 40C which is 5C higher than my E6600 @ 3.6Ghz with 1.5v.

Maybe just the new P32 bios reporting it wrongly?

It seems many E8400's have core temp sensors which report incorrect low temperature readings. These false readings are being reported in all software monitoring programs.

I had a E8400 which reported idle temps of 17C in one core and 34C in the other. Under load, the 34C core readings were frozen until it exceeded 34C.
I exchanged that processor a new one, albeit from the exact same batch, but the new cpu more correctly has core temps of 38C/36C (4.0Ghz with 1.34v).

Programs like CoreTemp read the diode right in the cpu, so software updates or bios upgrades will have no effect on these false readings.

Some E8400 purchasers are being told to just ignore these false core readings and instead rely on the "cpu temp" reading, rather than core temps.

Ok i'll re-word.... Can any one posting there OC's here who are using retail wolfdales brought from overclockers please post there batch numbers when posting results.

I really want to know if the situation is the same as it was when the G0 stepping q6600's came out in the europe got "B" batches while everywhere else got "A" batches.

Weescott your a cheeky chappie :D
 
Testing a cpu clock is done using small FFT as it stresses the cpu more than blend.

Small FFT maximum heat maximum stress.

At that conservative clock Blend is not the ideal test.

You test the cpu stability before the systems, and the temps would much higher on Prime95 and small ftts,enough to fail.

Period.
 
Regardless of what you say, this is the way I have always tested. I ran my E6600 3.6Ghz testing this way for a whole year without so much as a hiccup. I don't need to comply your rules for my OC to be "accepted" so pull the other one before you start getting arsey.
