It should start up just fine with 1600C9, I donÂ´t think you have faulty ram but to be sure you can run Memtest86+
or HCI Design Memtest
with the one stick at the time in either slot 3 or 4.
Check so that it doesnÂ´t run the ram with the XMP profile, it might cause problem since the Ripjaws was intended for the P55 chipset, set the frequency and timing manual to 1333 9-9-9 28 2N 1,50v and try with then in slot 1 3 or 2 4.
Another thing to check is if thereÂ´s any bend pin in the CPU socket, since the memory controller is in the CPU and if a pin is not in contact with the CPU it might causes the fault.
What cooler do you run?
Why I ask is that you may have seated it to tight, to loose or it might not be seated even on the CPU, those things might also cause the problem.
Btw, welcome to OCN
, hope you going to like it, great forum.
In the User CP you can fill out your "System Information", easier for people to help when they know what gear you run.Edited by Ghostleader - 5/26/11 at 10:06pm
