I have a dell xps 720, with a intel quad q6600 processor and windows 7 64bit. I have been using for some time now 2 sets of Ocz reaper OCZ2RPR8002GK ddr2 800 pc2 6400 2 x 1gb = 4gb total. Ddr2 800 pc2 6400 is the highest my motherboard can handle. It says in my dell xps 720 manual that I can have 4gb with a 32bit system and 8gb of memmory with a 64bit system. I recently bought 2 sets of Ocz reaper OCZ2RPR800C44GK Ddr2 800 pc2 6400 2 x 2gb = 8gb total. I put the memory in and got a blue screen, tried about 3 times each time getting the blue screen. My motherboard bios is up to date also. Then I put the original memory back in the 2 x 1gb = 4gb and now none of my usbs seem to be working. Please help, anything would be much appriciated. I dont know if my problem is intel q6600 does not support 8gb of ram? But putting the old ram back in and having the usbs not working seems a little odd. I think intels q6600 supports up to 8gb of ddr2 1066, I could be wrong. If anyone has any ideas please put your input, thank you.
maybe pushing in the ram slots put to much strain on the mobo, and so some traces were damaged? i am saying this because dell probably tried to save money and time and put as few screws as possible in there.
