I was update new 1401 bios for my r6a
4000 cl15 ram is ok
but if I work 4200 ram
the always debug code "bd"
my mems is HOF Extreme 8*4 and cpu 7960x
and then, I switched bios2 (1004)
4200cl15 1T is perfectly normal
74304

this is same setting with 1401
so
I think 1401 maybe is a very bad bios
or somebody can works 4200 ram in 1401?

The MemOK button will retrain the RAM and potentially acquire a better overclock by using more stable tertiary timings for the RAM.

According to the manual 4133 is the max specified for a CPU with 6 or more cores ie the 7960x. Getting any higher is lucky.

4200 quad need a good IMC and good motherboard
Obviously I conform these condition
but 1401 is a very bad bios
