Well, I miss MAL options in both BIOS and Memtest. There's Maximum Read Latency at 54 or so. It freezes at 50~51. But indeed this setting has a big impact, and MAL had a huge impact on X2. That's why I ran RAM 1:1 to get tighter MAL. With a devider I could only get 6~7, with 1:1 4ns was the best I could.

Ill try upping multi from 11.5 to 12 for CPU sometime and check whether Special Add would help better than normal Vcore.
