I have been having some big memory problems. I have 1 gig of Kingston ValueRAM (2 512 sticks). Every once in a while programs would crash. It would happen mostly when I put alot in the memory and started using more of it. I am not coming near my 1 gig when running apps, the most I will use it 85% of it and it happens rarely. When I overclock the CPU and memory it happens more. When the whole system is at stock it still happens. I ran MemTest86 and it said I have 752 memory errors.
I am guessing I better call Kingston and get new memory (I have a lifetime warrenty).
