Strange probs with a H55m-UD2H board

[owldbartle]

i have been running an I7 processor on this board and recently i bought an I3 550 cpu i tried it in the board and it gets stuck in a loop never reaching post,i have taken all my 8 gb memory out and tried it with 1 stick and 2 sticks with and without a grafix card all to no avail my psu is a ocz 900w with a asus hd 6770 grafix card and 8 gig of kingston 1333 ram,odd thing is it works fine with the I7 cpu just it does not read the memory correctly reads it as 4 gig only and i am running win 7 64 so it it should be fine but its not any ideas anyone ?

Hi

It will only support that CPU if you are running with F8 BIOS version or later. What version have you got installed ?

[owldbartle]

F11

[Dark Mantis]

Well that rules that out then. I suppose that you are still using the F11  version and it hasn't reverted back to the Backup BIOS version with whatever is on there ?

Have you checked that all the power cables are still attached properly. That is the 24 pin and the 8 pin on the motherboard and the two connectors on the graphics card ?

[owldbartle]

there is no connector on the grafix cardand only a 4pin plug for the cp,only recognizes 4 gig of memory ,checked the memory out in my other rig and it works fine,showing dual channel in the biosso the memory is fine all seems a bit odd duff motherboard perhaps?

Possibly the motherboard is at fault but equally likely is that the memory isn't compatible with it.
