My computer has an issue that results in random crashes. When I run memtest I get the same errors almost immediately (pictured).
They always occur at the same addresses even if I swap the sticks around, so I know the issue is with the PC not the memory. The errors only occur if slot 4 or above (of 6) is occupied on the motherboard.
At this point I would replace it, however the installed Core i7, having the Nehalem architecture, has the memory controller on board - so it could just as easily be this, no?
Without replacing the CPU (I don't have a spare), is there any way to tell if this issue is on the motherboard or the CPU itself?
