I installed 8gb (2x4) of hyper x fury 2400mhz RAM to go along with the set already in my pc and now my pc seems to crash after about 20 minutes of playing a game. I've used cpuz and the only problem, or oddity, I could find is that slots 1 and 2 have slightly different timings to 3 and 4. I've tried moving the RAM around in different slots as well as increasing the voltage by 0.05. I'm aware if sometimes you buy RAM not in a set it won't function with another set but if possible I would like to go on using this RAM so any help would be appreciated.
