I’d make sure you bump the voltage… I experienced crashes on an ASUS board with mostly stock settings when attempting to go from 64GB to 128GB ECC … it was only once I manually set the voltage on the memory slightly above spec (1.2V spec … set it to 1.25V)
I started with the lowest clocks… and just kept slowly bumping up until I hit the spec on the package… 3200 Mhz
if this doesn’t work I’d probably yes… look at getting sticks off the QVL like I did.
