Picked up this board and some other parts last week. Got it all up and running as follows.

Vista64
P5E Bios 902 (came with 702)
E8400 E0
2 WD raptor 150's(from my last build)
Gskill 2x2 4gb 8500

Unit is water-cooled in the new Cool Master Half case. It turned out really nice lots of room to work in.

Having some problems with the CPU temp. I have removed it 2 times now with no change.

I have read this is a normal problem with the E8400s I had hoped it was fixed on the E0 units.

Also I have tried a few temp programs Speedfan, Coretemp, real temp all of them sit at 35C or 40C and never moved.

So I let it run prime95 10 hours and it never moved. Ran OCCT and it never moved.

Is it the Board or the CPU? Anything I can try? How about the RF0407 bios?

Also when I first got the board and got it up and running the Bios(702) kept telling me the CPU was unknown and showed 100C pretty much a garbage reading Flashed to RF0403 and it said the same thing. Flashed to 0903 and it went down to 35 or 40 and stuck there I haven’t been back into see if its moved at all in the bios as I was busy just finishing the installs.

Thanks for any help or ideas kind of a bummer of a rebuild. Been doing this stuff for 11+ years haven’t seen this kind of problem before
