I have noticed that my computer is no longer recognising both RAM sticks in my PC, I have gone into my BIOS and that seems to recognise it and even when I look at my system specs it even says that I have 16GB installed but only 7.94GB is available.
I have tried the usual fixes by switching my RAM around on the motherboard and when I booted up with one stick of RAM they both work completely fine.
One thing I did notice though was when I tried to boot my RAM on the A2 slot on my motherboard I would get an error code which meant that my RAM was not seated properly, I made sure that I heard the click when I inserted the RAM so I know that it is seated properly.
my motherboard user manual says that the optimal RAM seating would be A2 and B2 but A2 doesnt work as far as I am concerned, would seating my RAM in A1 and B1 make the RAM any slower?
I think my motherboard may be faulty and I just wanted to check to see if there was any other potential fix before sending it back to be replaced!

Any help will be appreciated. thanks. :)

Solution
Try keeping your RAM in slots that work together, you moved them around so im assuming you know which those are, but before you do that reset your CMOS battery, once you do that, then plug your RAM in, your mobo for some reason may be searching for a different frequency in the slot that your RAM is plugged into, so that could be why its not detecting it. Just google how to reset CMOS battery, quick and easy tutorials :)
