z270 Formula IX Delidded 7700K (late 16/ early 17), 4.9Ghz 16 Gb Corsair Vengeance 3200 SLI MSI Gaming X 1070 So.... To keep this short I went water to see how much better it was going to be than the Noctua D15. I don’t know how long the system was frozen but I realized that HWMon wasn’t updating anymore before I figured something was wrong. CPU was only 70c unresponsive... After the stress test failed, I could only boot with 1 out of two sticks of ram. System is stable on a single stick. Both sticks work fine in other systems and pass short term memory test, however, those sticks do not work on the Asus. I’ve tried booting off one and lowering the DRAM speed and popping in the second one. I also adjusted the power to 1.35v and popped in the second one to see if it boots. Both of these end in Q code 55 (memory not present) and cycles through soft boots. Right now I pulled CMOS and unplugged it to see if tomorrow is a better day. Any other suggestions? Because right now I feel like I might have semi nuked my 7700. TLDR, overclock and/or stress test went bad and now board only boots with a single stick of memory in any slot.
