I want to upgrade the CPU and i got a cheap I5 3570K - Now the problem is comming.
When i mount the new i5 3570k i got the fail code "55" on the MB digital number flash. And when i lookt it up, i see its RAM LOADING FAIL. Hmm. But when i then mount the i5 3550 again its all ok and the com boots just right up!!
Hmm. I then think. a bios upgrade must do it! It was at stuck 1.4 i mean, and with the i5 3550 mounted i booted it up - and upgrade the bios through uefi to the lates version 2.1 i think it was called.
I looket up at the producent homepage -
1155 Core i5 i5-3570K(E1) Ivy Bridge 3.4GHz BLK 100MHz 6MB 77W P1.20
1155 Core i5 i5-3570K(E0) Ivy Bridge 3.4GHz BLK 100MHz 6MB 77W P1.20
1155 Core i5 i5-3570(N0) Ivy Bridge 3.4GHz BLK 100MHz 6MB 77W P1.40
Bios supported since, and it should work should it?!
I really dont know whats wrong - does anyone know ?? Or is it just simple, the CPU is dead on arrival?
I you suggested already, it could simply be a faulty CPU. Maybe some problem with the memory controller in the CPU. Try testing it with 4 memory modules in another motherboard and with a BIOS version that supports the CPU.
You can also test with a single memory module to see if that makes a difference.
And with the new CPU in place, try clearCMOS. The procedure to do that should be described in the manual.
