Seem to be having some issues with my RAM. I just took out 2x 1gb (800) sticks and replaced with 2x 2gb (1066) ones, but my PC doesnt always seem to recognise them.
When I run dxdiag it comes up with 3582mb of ram (32bit vista only) but I've done some benchmarking (e.g. pc mark) and it only seems to recognise "available ram" as 2387mb.
Also, i'm playing a few games at the moment (Aion for one) and noticed that in some sessions it runs smoothly everywhere, other times it plays like it did before i installed the new ram and FPS drop to half ish.
I'm wondering if either I didnt slot them in correctly or perhaps my motherboard cant handle the 1066? Have a gigabyte 965pds3p, duo 2.4, 8800GTS.
