So, the story:
Built my machine a year ago with an Aorus Z390 Master, 8086K CPU and 2x16GB 3200 C14 Gskill ram ( https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232218?Item=N82E16820232218 ). I enabled XMP on that with no issues. Ran 1600MHz at 14-14-14-34 right off the bat. A while ago I swapped in a 9900KS and put the 8086K in the fiance's ITX build. Then the machine would not run XMP at all. I left it alone until yesterday when I decided to twist the machine's arm a bit. I want my ram running at spec or better! I know the CPUs are only spec'ed for 1333/DDR4-2666, but I've read that these new CPUs have pretty good memory controllers.
I enabled XMP, but proceeded to manually change the memory speeds and set the voltage to 1.35V. SPD is 15-15-15-36-50, so when I say C15 below those are the timings I'm referencing. When C14, it's 14-14-14-34-48. Pass is getting to Windows and running an Aida64 speed test. Fail is CMOS getting reset.
Here's what I got:
800 C14 - pass
1066 C15 - pass
1066 C14 - pass
1200 C15 - pass
1200 C14 - pass
1333 C14 - pass (stock CPU memory speed)
1466 C14 - pass. I boosted VCCIO to 1.15V, Sysagent 1.15, PCHcore to 1.06. More just in case than anything else. I really don't know what I'm doing here so I kept the voltages modest.
1500 C15 - pass
1600 C15 - pass. Could not replicate after the bios would not accept the next speed below.
1600 C14 - fail. This is the XMP timings I'm trying for.
Currently at 1500 C15.
Bios is the current release at F11c.
Would gladly accept input on how to get this working better. Just for fun, a nice round 50GB/sec read speed would be sweet, if not a bit more. Topped out at 46-48GB/sec I think.
