Hi
I have a problem with my asus p7p55d-e
My [ Ripjaws] F3-12800CL9S-2GBRL is not regognized on dimm A1.
The computer don't boot...
If I put two memories on slots A1 & B1, computer boot but only 2go are recognized by the bios...
If i put on memory on B1, computer boots
if i put memories on B1 and A2 4go are recognized but i loose the dual channel...
Do you have an idea ?

Thanks and exuse me for my bad english...

If you've tried the different sticks in A1 and get nowhere with either, then you probably have a bad slot. You could try using a can of compressed air to try and clean out the slot. If mobo can't be exchanged, might try in A2 and B2, but best would be to see if you can replace/exchange

A2 and B2 don't work too...

Many people say that the problem comes from the compatibility between ram and CM...

This ram is not listed by asus as compatible...

GSkill folks may have a better idea on the combo, should be in Monday

Thanks a lot. i'll wait.

They are definitely compatible. Sounds like slot A1 is defective.

Thank you
