Asrock Z68 Extreme4 Gen3-No XMP & 2 out of 4 RAM

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi!

Recently I have something weird. After resetting my bios due to my pc not starting up, all of a sudden i can not see 2 of the 4 memory sticks. However, when i use a program like Hwinfo or CPU-Z then I see ALL 4 RAM.

In the bios also my speed is 1333. That is not weird because the XMP profile needs to be set in the bios. However, there is no "Load XMP Profile" button anymore, while i did have this before.

I have tried to downgrade my bios back to 2.30 - No fix
Reseated my CPU checking for bent pins - No Fix
I have put in 1 pair of RAM - both pairs can be seen if they are seperate. But once all 4 are in, I only see 2. 
When i try to put in 1 pair in every dual channel mode then it works.: A1/B1, A2/B2. When A1/A2/B1/B2 is used, only A1/B1 can be seen.

Info:
CPU: Intel I7-2600K
Bios Version: 2.31A

I hope someone can give me advice.

Thank you in advance!
