Hi all. I've been running 32gb (2x, 2x 8gb sticks) in my pc for a couple of years now and a couple of months ago I started getting random crashes, mostly when the pc is left idle. This steadily got worse and worse until crashes and freezes would happen a couple of minutes after booting up. I've replaced the PSU and done all the required testing such as reinstalling windows, installing windows on 2 different SSDs, updating bios, reset bios and cmos, ran memtests, removed overclocking, unplugged everything and ran as a bare system, try each ram stick individually in different slots, reseated CPU, repasted GPU and CPU and still I would get crashes. In the end I just threw a curve ball in and enabled xmp1 in the bios and strangely the pc ran for much longer before crashing/freezing. I then decided to up the voltage on the ram in xmp1 to 1.3900v and the pc has been running for 10 hours without crashing. Does anyone have any idea why this would be? Is my memory on the way out? Is my mobo faulty? Is the memory controller in the CPU on the way out? Specs are: Cpu Intel i9 9900k Ram 32gb gskill trident z f4 3200c16 8g tzr 2 packs of 2x 8gb.
