So used a rockit tool to de-lid/re-lid my 7700k. Plugged it into a new build asus tuf z270 mark 1, wouldn't boot, leds said bad memory. ordered new ram, still the same error led. So, put in a new untouched 7700k, everything is fat, dumb and happy, just the temps change very slowly under stress (using a new noctua nh-d15), but maxes out at 70c, idle is 32c, room temp is 23c-ish. I used almost exactly the same steps (to give me some wiggle room in case I screwed something up), used the same gasket sealer that Kyle used with the rockit re-lid tool. I'm going to pop off the spreader and try again, but anything I should look out for this time around, always assuming that I didn't bork it up completely?
