How do I get my 2400 MHz mem to actually run at 2400?

post #1 of 5
Thread Starter 
New build, everything still at stock. I ran 3Dmark and noticed it's said 667 MHz so I doublechecked with CPU-Z and it says ~668 MHz. Since it's Double Data Rate it only runs at 1333MHz.
Before I start screwing up bios setting and what not, what do I need to do to make it run at at least 2400?
Is it supposed to run guaranteed at full speed?
Is it compatible with the Sabertooth Z77? It didn't list this kit as compatible in the manual but it probably didn't even exist when that was printed. The list in the manual was very short.

16GB (4 x 4GB) HyperX Predator, DDR3 2400MHz, CL11

You have to load the XMP Profile in the Bios, which should set correct timings and speed or simply change speed from 1333MHz to 2400MHz in Bios.

Either set up the XMP profile which is somewhere in the BIOS or manually overclock your RAM by entering the settings which the kit is rated for. In your case that's 2400MHz, CL11 and 1.65V.

Thanks! I set it manually to 2400 because I could not find any way to "enable, run or load" XMP. Does it matter if set it manually instead of profile? The timings seem right: 11-13-13-30-2T. Anything else the profile does?

Also, is there any point in trying to adjust my timings?
