Also having major issue's with the ram. When i do a ram test with OCCT after 15 mins it always seems to crash. even with loose timings of 8-7-6-21 i am hitting the same issue's. The problem is i am running 2.10volts through my ram i do not want to run more then that for 24/7 use. Also tried switching the ram sticks, no difference. Does anyone have any idea's where i am going wrong?
