I'm lost, i don't know what to think anymore...

Today i got my new E8500 with FPO# Q745A554, a batch that does well for others so i couldn't wait to get her in.

Booted fine and all but the first dissapointment came when i opened coretemp...1.1125VID which is exceptional high for an E8500 but ok.

Next thing was a problem more people have reported, one core is 33ºC the other is 48ºC, idle!!

Under load the hot core gets up to 60ºC, this must be the cpu cause my E8400 had just 38ºC idle on both cores.

Now onto something bigger, getting 4Ghz stable.
1.25V in windows, Prime 95 runs but just closes after a couple of minutes without an error warning or something, same goes for orthos. wtf??

I ended up giving it 1.31V in windows which droops to 1.304V to run occt stable.
This must be the very first E8500 that needs 1.3V for 4GHz.

I played with all possible voltages in bios, Vpll, GTL, termination voltage, NB, SB, you name it, all to no avail, the only thing that seems to help is Vcore.

I could run 3d mark 01 at 474x9.5=4.5Ghz at 1.52V and could do 1M close to 4.6GHz at that voltage.

I really suspect my motherboard, it either hates wolfdales or wolfdales just hate me.

Gonna have to break out the wallet again for a new mobo i'm afraid.

I'll be glad when i've had enough of this.

Damn.
