I was always finding poor performance for memory on the board until I found the culprit settings which were at fault thus far. (beyond poor performance)

Settings to look for:
RedirectForReturnDis "1"
L2 TLB Associativity "1"
Enable IBS "disabled"

Chipselect Interleaving "disabled"
BankGroupSwap "enabled"
BankGroupSwapAlt "disabled"

You don't want IBS enabled, neither do you want BankGroupSwapAlt enabled, they cause significant performance drop on you memory.

Other settings not directly tied to memory are(security workarounds I think):
STIBP Status "disabled" (single thread instruction branch predictor?)
NX Mode "disabled" (non execute page function? doesn't do much but maybe affects FPS at times)
