2133mhz RAM only stable at 1866mhz

Hi

I recently bought new RAM and a SSD. I got the 16gb corsair ddr3, 2133mhz kit and Samsung 850Evo. My motherboard is a gigabyte p67A-UD3-B3 flashed to latest BIOS F9.

So I've installed the RAM and SSD. I had to install the RAM into the 2nd dual channel due to the height of it, it wouldn't fit with the CPU heat sink fan in channel 1. But they're still in the correct colour coded channel and the manual doesn't explicitly state it makes a difference which channel you place RAM in. I can't test swapping channels with the height of this RAM.

In BIOS there's only 1 option under XMP and that's profile 1 for 1866mhz. There is no option 2. I've also flashed to the latest F9 BIOS.

I tried setting it manually to 2133mhz, but the system was unstable and I got an overclock unstable warning message in BIOS.

Question, I can't initialise 2133mhz because either the motherboard doesn't support it, even though it said so in the manual, it's cause the RAMs in the secondary dual memory slots, or its faulty ram?

So at the moment I've got 2133mhz RAM running at 1866mhz.

Here's screenshots of the BIOS settings, the first 2 are at 2133mhz unstable setting. The 3rd is the timings which stay the same regardless. The last is of the stable setting that set automatically with XMP profile 1.

Any help would be appreciated.

Thanks

Those corsair kits use 1.65v at their advertised speeds,your screenies show them at 1.5v when your trying to run them at 2133mhz.

Bump up the ram voltage to 1.65v and try them at 2133 again

But shouldn't it show an option 2 under XMP for 2133mhz mode?
