Hi folks, I've come to find that my system has become unstable after enjoying nearly a year of light overclocking after installing the Windows update for the Meltdown patch. Firstly my OC (may not reflect outdated specs in sig sorry): 7700k, 4.8Ghz, 1.24v (4.5 Ring + 4.5 AVX @ 1.21v) MSI Xpower Titanium Z270, LLC mode 2 (dead flat) GSkill 32GB 3200Mhz C15, 1.36v, SA 1.15V, IO 1.15V (both 1.16-1.17 on physical probe) This test previously passed OCCT Linpack for 10 hours, passes many loops of 3D Mark etc and a good few hours of Prime95 mixed. Linpack in OCCT is completely broken as soon as it hits 100% CPU usage, PRime95 may last a few minutes, even when BIOS is cleared and reverted to default. Either reboots with no warning, or occasionally produced WHEA 0x124. I have even attempted 1.3v and it fails at everything else stock (no xmp or wehatever) I've been noticing general instability in some games, and other heavy apps I use, usually the type of thing I attribute to slight Vcore starvation or IO/SA starvation. But after various tests I can't deem anything stable, prime95 and OCCT Linpack are unusable to do any stress testing, the will crash the PC at 100% usage. However the Intel processor diagnostic passes every single one of them. For shits and giggles I setup a non-XMP 4.8Ghz @1.2v (LLC 2) and it passed the Intel PDT. That should lead to Vcore related BSODs in most good torture tests, so this is straight up BS. Anybody out there sporting an overclock, and maybe even just those with decent enough hardware or whatever, can you please check your systems for any instability and confirm this is the case. I have found a couple of reddits with similar posts but the info is few and far between at this point.
