Problem 4 Ram slots

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

   Hello guys, I need some help. 

My motherboard is Asrock z77 Extreme4. I have been using 2x4gb ram and recently I got 2 extra 2x4gb to increase my total ram to 16gb. I bought the same model and latency. The model is: G-skill DDR3 2133. 

So, my pc doesn?�t detect 16gb, I tried lots of different configurations and It always detects 8gb. I tried one slot with old ram and another slot with new ram and it works, so it seems that is not a compatibility problem. 

If I access the bios configuration, I can see at the system browser that detects all 4 slots. However, they are only working 2 slots which are connected in A2+B2 slots. It seems that if I plug 4 slots at the same time, A1+B1 are not working. 

Any solutions? Than you very much

	Have you tried running them at stock 1600 instead of the OC 2133 ?

	Thanks for the answer. How can I change that? Anyway, I think they are already running at 1600 as I can see at BIOS
