I have 64GB quad-channel 2400MHz kit of F3-19200CL10Q2-64GBZHD ( my second, I had to return the first because it was defective ) running on a Rampage IV Extreme with a 3970X but for the life of me I cannot get it to run at 2400MHz. I currently have the memory clocked at 9-11-11-31 at 2133MHz and it runs fine. Priming for 24 hours results in no errors. But if I use the default XMP profile #1 and run it at 2400MHz Prime95 will almost immediately stop with a rounding error within at least 10 minutes.
I've tried following the Rampage IV Extreme RAM Guide and also increasing the latencies / relaxing the timings to no avail -- I get the same rounding errors in Prime95.
I have to restate that it's running fine at 2133MHz 9-11-11-31-2T.
Can anyone help?
thanks,
