Hello,
i just got the ballistix 8gb kit "2-4 gb ddr3 ballistix, pc3-12800 cl9. 1.5v for my windows xp cpu but when i changed the ram, the computer crashes. i reinstalled the 2gb and it still crashes/ though, when i installed back to the old RAM, it did ask me to either let the default take over or manually fix it. my processor is: intel (R) Core (TM) i5-2300 cpu @ 2.8GHz, 2.79 GHz 1.90gb./ram
please help, thanks
