I had 2 x 8gb XMS3 DDR3 sticks in my computer, sold one and had the other. I then went to 4 x crucial tactical, which I sold recently. I put back in the XMS3 stick and then I started getting blue screens. Firstly stuff relating to microsoft drivers (ntskrnl), then "memory_management".
I stuck in a 2 gb DDR3 stick with hardly any use, and then installed windows 10, which it worked fine for (would have given errors with the 8gb stick in). I've now put the 8gb back in and haven't had a bluescreen, albeit, for a few minutes as I am typing this.
I ran memtest on the 8gb stick and it froze after 26 minutes, but up to that point, no errors.
Has anyone any idea what might be the problem? I thought it was the ram but seemingly not, I thought it was storage but all worked fine plugged in as external drives and now all plugged in and no problems with them... The computer isn't old, built this time last year. The ram is the oldest component (march 2013), but like I said, hasn't been used that much.
