CMY16GX3M2A2400C11R DDR3 2400mhz issues z68


Recommended Posts

So I've been running my cpu at 4.4ghz 1.35v and memory at 1.65v at 2000mhz for a while. Cold boots fine, completely stable.


I have 2x 8gb modules in dimms 1 and 3


Yesterday I upped the memory speed to 2400mhz, booted into windows, gamed for several hours, ran stress tests, etc. No issues. 11-13-13-33 (tested latency is 11-13-13-31, couldn't get it to post at this timings.)


My final test, I shut the system down and tried to boot. I get the classic blank screen and then the system powers off.


Ideally, I would like to run this memory at the tested latency and have it stable so I can game / shut down and cold start my system.


It should be noted that my mobo doesn't play nice with the XMP, which is why I am manually setting timings / voltages. When I load the XMP profile no settings change and I will get beeps if I save the bios and reset the system.


Any help is greatly appreciated.
