CPU-Z showing 24GB of RAM, Task Manager only showing 12.

I recently just bought a Kingston HyperX FURY 8GB 1866MHz DDR3, a second one to match my other one.

I was using one of that stick plus I had a pair of G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM DDR3 1600. This was giving me 12 GB of RAM, one stick being 4GB and the other being 8GB.

CPU-Z says I have 24 GB, like I should with all 4 of these sticks plugged in. But task manager (and BIOS) says otherwise. In CPU-Z it says that the two 8GB sticks are using 888 MHz and the 4GB ones are using 800MHz.

My Motherboard is an ASUS P8Z77-V LK, BIOS is up to date.

I read that RAM can underclock itself if its MHz are more than what the mobo asks for? Shouldn't all of this be working then? Or will I have to return these and buy 1600 MHz sticks?

Edit: CPU-Z says that I only have dual channel up, instead of quad? But it's bizarre because it's selecting one of the 4gb and one of the 8gb, creating 12, rather than picking 4/4 or 8/8?

You need to check the slots that you have them plugged into.

Your motherboard will have 2 channels, 2 slots closest to CPU is A and 2 slots away from CPU is B.
Try your 2 8GB sticks in Channel A.

Does this give you 16GB?

Then you can add the two 4GB sticks into channel B

Yeah I just figured that out, I now have 16 GB because I have the right combo of 8/8 in the slots. But task manager still says only 2/4 slots are being used. Think thats just cause the channels are bad? Cause the sticks seem to work fine.


Edit: Though the A and B parts are every other, so it's slot 1 and 3, then 2 and 4. I think. (1 and 3 are black, 2 and 4 are blue).
