Can you try lowering your max cache ratio from bios to 42? It is set to "auto" by default and this makes it run a bit faster (NB frequency on cpu-z memory tab). Also I would recommend running VCCSA=1,15V and VCCIO=1,10V for ram speeds above 3200MHz, something lower like 1,10V and 1,05V respectively might work, but having both at 1,00V with those memory speeds is not really recommeded, since VCCSA defaults to 1,05V and VCCIO to 0,95V at the SPD speeds (2133MHz).
You could also downgrade to bios 0802 since I have seen some people mentioning that the bios 1003 has made their memory overclocks worse.
I have the CMR16GX4M2C34 2x8 GB 3466 MHz CL 16 kit.
I had a lot of errors before on my "old" i7 8700K processor but I had another one here too so I tried that one in case it just was the memory controller. On ASUS Z370-F Strix with 0607.
The first screenshot below is likely memtest86 sequential test #6 block move for one hour on the ASUS Z370-F Strix BIOS 0607 with another i7 8700K. 284 errors.
At the same time I bought this motherboard I had also ordered an MSI Z370 Gaming M5 because this was on black friday and both was on sale. Though the ASUS board have better sound and the one I really wanted was the Z370-E Strix. But it's time to return items and I figured I'd put it together anyway. The second "to try if it's better" i7 8700K I've now returned so this is my same old processor which also never have worked on the ASUS board with XMP on.
The second image show this processor simply with XMP on and I think the FULL test and with parallell processor core usage.
The second image show the same processor still on the Z370 Gaming M5 (BIOS 1.20) simply with XMP on and parallell processor core usage and only test 6 block move for 1 hour 30 minutes and 52 passes with no errors.
My RAM is on the QVL for the ASUS board but it's not on the QVL for the MSI board. But clearly it work better there. Also as I've tried TWO i7 8700K I doubt it's all that much of "bad luck."
On the MSI board however if I choose sequential core usage and still do test 6 then the program simply seem to hang after 4 seconds. It stopped updating after that at-least. Tried it twice and same result both times.
HWmonitor list +0.000V for the offset value for SA don't remember what the other one was but IA, GT, LLC/Ring is all +0.000. VID min 0.670 and max 1.345.
CPU-Z says: 1741.9 MHz, FSB:DRAM 1:26, CL, tRCD, tRP and tRAS: 16-18-18-36, tRFC / Row Refresh cycle Time: 607 cycles, Command Rate / CR: 2T
No idea whatever that would be of any help on the ASUS board. It's really about my last change to return any of these so I really should make a decision. I've never used the MSI board before and at-least the Pro Carbon AC (Pro) has shown worse audio test results than the Strix one in some benchmark likely / possibly because of better input on the ASUS board since they claim they have improved that and it was likely tested using a loop between the output and input. Also the MSI board come with Killer NIC which use more CPU and did cost 200 SEK more though it's normally cheaper (came with Assassin´s Creed Origins) otherwise I guess they are pretty similar. ASUS RGB solution is much more shiny also everything whatever it's heat-sinks, capacitors for the VRM or for the audio look larger on the ASUS board. No idea if that says "quality" but assuming the ASUS board worked as well I would likely had preferred that. Now it's harder. Also my case is old and I have no cut-out so switching from one to the other force me to rebuild the whole setup.
Because of what seem to be that complete lock-up maybe I can't be sure it work on the MSI board either. Unless I get it going on the ASUS board .. I will have a hard time to decide what to do =P
Edit: I'm still upset simply changing the frequency to 3200 MHz put the memory controller and RAM at 1.5 volt!!
Plenty of people seem to have problem with the Corsair kits on the ASUS boards?
I've copied all the values which the MSI BIOS showed in case that can help run it on the ASUS board too.
CPU IO seem to be 1.25 volt and CPU SA 1.31 at-least.
(Also is there a tiny red dot at the middle row left most half of the CPU socket furthest to the right? My eye-sight and brightness isn't enough to see. Maybe it's a piece of dust? How convenient!
