ram timing question

[amorphous]

ok i know very little about ram timings and over clocking etc but i have been having issues with windows 7 freezing and someone suggested it could be ram timings

i have 4Gb of corsair dominator ram installed with intially timings of 5-5-5-18 but according to corsair it should be 5-5-5-15, would this be enough t cause windows to freeze? seems to happens when moving files or downloading

Have you manually set the voltage for the ram ?

Your higher TRAS value should actually improve stability if anything.

Look at voltages, inc the MCH if you have 4 sticks.
