Hello guys I recently built up a new pc with kingston blu memory branded at 1600mhz. As expected it ran at 1333mhz at default which i set to 1600mhz.PC ran well for about 5 days then i got a random shutdown that took like 10 mins before it became bootable again. When i restarted the memory switched back to 1333mhz and since then ive never tried to increase the speed again and everything has been running perfectly. My main question is how much a difference does the speed difference actually affect performance, these parts werent cheap and i rather not have random shutdowns occur.
