Ended up winning a free 8086k on the giveaway a while back. So I finally got around to a delid/relid and installed the processor yesterday. I'm having and issue where the vCore will dip a large amount when running AVX processes so I'm having a hard time running stress tests to verify a solid OC. First, specs: EVGA Z370 Classified K mobo 32GB G.Skil 3600MHz DDR4 (4x8GB) Seasonic Focus Plus Gold 850w EVGA 1080Ti SC2 Black XSPC Raystorm Neo CPU block EVGA water block on 1080Ti XSPC D5 photon v2 pump with 270ml resovoir XSPC RX360 360mm radiator running XSPC EC6 coolant 6x Noctua NF-A12x25 fans on radiator in push/pull i7 8086k settings: CPU Multi = 50 Ring = 50 (I've tried from 40 to 50 trying to see if this changes anything) vCore = Adaptive at 1.20v VCCSA = 1.26v VCCIO = 1.26v vdroop = auto/enable RAM is set to XMP 1 = 3600MHz at 1.35v Temperatures in AVX loads (for as long as they will run) are around 65-70c with an ambient of 83f, and run around 45-50c in games/other processes at the same 83f ambient. Now, when I boot into Windows all is well and stable. Sitting at desktop and opening windows/programs the CPU will clock at 5GHz and run anywhere from 1.25v to 1.31v, same with non-AVX processes, games, etc. When I launch up Cinebench, prime95, or any other process that can/does use AVX instructions the vCore will drop to 1.108v - 1.15v and will fail after a few minutes. I've tried changing the adaptive voltage all the way up to 1.45v and it will still drop to 1.15-1.2v when running an AVX threaded process. I've also tried changing the AVX offset from 1 to 3 with the same results, although the tests don't fail when AVX offset is set. The same issue happens when I set the vCore to static/override. When turning off the vdroop, I have to run vCore at 1.2v with a -180mv offset for the voltage not to spike up to over 1.5, but the computer is not stable in normal processes with the voltage dropping so low at lower loads. The EVGA BIOS does not have a setting for LLC, so that's not something I can mess with. To get to the main point; is there anything else that can be done to stop the vCore drops when running AVX loads to properly test stability? I have no stability issues in games or normal processes at 5GHz with my current settings, but I am unable to run an AVX stress test successfully due to the vCore dropping so much during AVX stress. Should I just not worry about AVX stress tesing and run an AVX offset of 1 or 2? (AVX offset 1, which runs AVX loads at 4.9GHz, doesn't seem to fail even at 1.1v) Thanks for any advice/assistance and taking the time to read this long post.
