It turns out that while I was getting no errors in TM5 I was still getting errors in MemTest when only setting the primary settings.
1.4.1 fixes this. I had to set the primary settings (3200 @ 14-17-14-18-28) and then the "Sub-timing Configuration" in the OC section. The remaining "Turn Around Timing Configuration" was left to Auto and I was able to run MemTest with zero errors with the vDRAM set to 1.7.
(Posting images of these two sections in MSI BIOS configuration for those who are not aware of what values are in each of these sections and also to show what the Auto values are for the chips that I have)
Oh, and the RC was 42 and RFC was 419.2. 420 as suggested in 1.4.1 release notes seemed to do the trick.
However, I am still confused on something here after nearly two weeks of working with this board that isn't mentioned anywhere in the calculator or here on the forum that I can see.
The only way that I could get this board to POST was to set RTT_PARK to Disabled. Further, setting it to 43.3 was the best value to reduce errors that I could see.
I haven't seen anything regarding disabling RTT_PARK (only NOM) so I am wondering if there is something wrong with the board and/or if I should report it to MSI. I wanted to get confirmation here first before doing so.
My motivation for doing this is that these chips are QVL for the board and rated 3300 but I cannot get this board to POST over 3200 it seems no matter what I do. This also leads me to believe there might be an issue with the board to report to MSI to see what is up.
Thanks in advance for any assistance/context/clarification you can lend and again for all your great work here!
