Well, i've spent hours & hours changing timings & rebooting, running HCI & rebooting...etc.
Doesn't really help that i've updated bios pretty much every time a new one is out.
There are three sets of subtimings on this mobo, & unfortunately for my tweaking, one (or a few) of those timings affects HCI Memtest stability in a big way.
So i'm presently running the 1st set manually set to the same timings as auto puts them at, & the second & third set i've set one notch looser for each one, since auto sets one (or more) of them a wee bit too tight...just haven't figured out which one(s) wrecks stability...there's only like 12 to pick from
I've gotten to somewhere i'm pretty happy with in terms of performance, but also stability, though i'm still going to eventually try to figure out which of those remaining 12 subtimings prefers being set looser.

Gotten my Everest score up a bit too, & on stable settings.
I can get it quite a bit higher, but it'll fail HCI then...
