Actually I believe my ram is DDR3-1600 but it is auto set to 1333 and on my specification paper it says "MEMORY: 2X8192 MB DDR3-1866 CORSAIR VENGEANCE LOW PROFILE CL10 (PC-3-15000) 10-11-10-30
Hammog does that tell you anything? Should I ignore that the company put my RAM in 2 and 4 and open my computer and change it to 1 and 2. In the manual it saysFor optimum performance, when installing one memory module, we recommend that you install it in the DDR3_1 socket. When installing two memory modules, we recommend that you install them in the DDR3_1 and DDR3_2 sockets.
I'm looking at your motherboard manual right now, and it just hit me that you're using an X79 platform. In order to do dual channel, you MUST have the memory in DDR3_1 and DDR3_2. That would be one DIMM on the left side of the CPU and one DIMM on the right side of the CPU, in the two DIMM slots that are closest to the CPU socket. The company that built your PC must not have been familiar with that particular board.
I am surprised they didn't sell you 4x4GB modules and run that board in Quad Channel mode instead of 2x8GB modules and run in Dual Channel. X79 has capability of 4 memory channels, but only if you use 4 DIMMS!
Those Corsair Vengeance CL10 modules should be running at 1.50 volts in the BIOS. Make sure they didn't accidentally set them for 1.35V. They might have thought the "LP" stood for Low Power, when in fact the LP really means "Low Profile". I've seen some ill-instructed builders set LP modules to 1.35V and have the same problem you describe. Also, those CL10 modules are the "slower" version of the Corsair 1866 line. When price comparing, take note there's also a 9-10-9-9-27 version as well that's a little more expensive. I don't care for Corsair Vengeance with regard to how many different models of RAM they have under that brand, with wildly varying specifications and appearances but very similar naming conventions.
