Hi Community,

I am looking for a bit of help. I recently got this motherboard with two sticks of Corsair 1333Mhz Ram at 4GB each. I already owned 2x 4GB Corsair 1067Mhz and I have plugged these as well.

My computer has all four installed correctly and everything seems to be detected fine. But my Total Physical Ram is only staying at 7.94GB. I was wondering if this is because I have four sticks of Ram and that two of them are different types. I know that with RAM at different frequencies the BIOS will tend to bring them all down to the lowest Mhz (all of them running at 1067Mhz) but I thought it would be fine to have all four sticks in this motherboard. I can't see anything on the manual on limitations on what Mhz to install, only that it needs to be DDR3 and not be 512mb or less sticks. Link to motherboard manual, if you can understand better than me: Manual

Could someone give me some advice please, do I need to get new RAM sticks which are more compatible or am I missing something? I heard something about memory remapping but I am not sure so any help is appreciated. I really want to get my 16GB of RAM working.

I have attached some pictures of the BIOS page with the reading on all four RAM sticks.
