EP45T-Extreme will not boot with wolfdales

[ObscureParadox]

As the title suggests, I can't get the damn thing to work with wolfdale CPUs which is the whole reason I got it in the first place

 

Boots fine with conroes though. Any advice on what is different between the two archs that might be causing me issues would be greatly appreciated

Any signs of damage in the PWM area?

 

I had a P5K-series board that would refuse to work with anything but Conroe after I replaced a blown up mosfet.

Any missing components somewhere? I had H55N USB which worked only with i3 due to some missing parts of the bottom.

im actually having the same issue in my 45Textreme now with a E8400 Wolfdale, i took it out of the P35T-DQ6 (working perfectly) coz i could only get 570 bus from it in it, and to try in the extreme and same deal, no boot, havent tried a conroe tho yet Lewis, and i know the 45 T extreme board worked last bench and the cpu is supported for the board, either the board has developed an issue, or the cpu has died is all i can think of

tried 3 different cpus, same reaction, unplugged the 8 pin power supply to the board and i get LED lights and the card spins up, plugged i get nothing so theres a short somewhere, so the board has a problem somewhere, probably the vrm area, theyre weak board, when they go they go ok, they arent as strong as made out to be, this is the 2nd of these boards ive had and ill never buy one of these again,

i found my problem, hope yours isnt the same lewis, looks to me that somehow its blown the top right and bottom left corners off the NB chip, oh well , another one gone

Seemingly no sign of damage but hard to tell with the VRMs since they are insulated. I'll check for missing components later tonight

This is very obscure and somehow paradox

[I.nfraR.ed]

Just speculating, but I'm with others saying it is a VRM problem.

I have something similar on an AM2+ board which only boots lower power single-core CPUs and the reason for this is a blown mosfet.

I'm starting to think the same also, had a go at a Q6600 on it today and it was really unhappy above 1.65v. Nevermind, I'm sure I can find another
