today i just change my memory to G.Skill F2-8000CL5D-4GBPQ

previously my d9 cannot run with 1:1.25 regardless th voltage that i give.

but now i can run it with 8x444 / 555@5-5-5-15

but if i use 9x444 it give me c1,which is so strange.i put 1:1 can post n stable.

so i think th divider problem got smt to do with memory ic
