i try down mem 1100 to 1090mhz but again have error
i try give more  power. now work with 870mv and i try with 920mv but again have error

pls any tutotrial what formula work with rp rc rfc ref  etc....

read back a little for formulas

if your hynix memclk is really 1100 then and it's stable at stock timings, then rfc and rc and rcdwr are too low imho.

i read all page but not see any forumula..(i go read again)

my mistake- 1100 for samsung. 1 samsung card always have error 1100 or 1090 .

Ram timings in nutshell
