Yeah, nothing worked and even get to POST. I had an evening of drinking Gin Rickeys and contorting to clear the CMOS every couple of minutes.
It was a 2x16gb kit so they are a matched pair, supposedly.
I'm going to have to get some better memory to bump up the speed of it apparently. The Sniper X memory 16GB modules do not agree with the Z390 FTW at any speed I tried above 2133. I put the VSA and VCCIO up to 1.35v at 3600 and 3200. No dice. I left the memory timings on auto and set the frequency to 2667 and 2400 w/o luck. It runs fine at 2133, so I'll leave it there for now. I may look at some of the other Sniper X timings that are certified for 2667 perhaps and try to apply them directly, and try the highest 1.2v rated timing (is that 2667?).
Buying antother memory kit most likely won't help. The imc on your cpu is most likely weak, and the only way to correct that is to get another cpu with a stronger imc. Gotta love silicon lottery. Did you also try running your ram at 1.35v along with the vsa and vccio at 1.35v?
Yes, I did. And I hope you're wrong about the CPU. :( I'm more hopeful that the memory is either not actually matched or that one or both are simply not up to the task of being run at faster than 2133. Since this RAM was the budget buy part of the build, that seems to be more likely. Also, a teachable moment for me. I need to read the specs better and pay attention beyond the "Ooooh, ahhhh, that's 3600 MHz. And it's cheap!" Cheap for sure. But no bargain.
If it is the case that a quality set of 2x16gb CL14 3200 DIMMs don't work any better, I will likely at least be able to run with 64GB at 2133MHz.
