M4a785td-v evo and 8GB f3-10666cl9-2gbnq
Hello, I bought M4a785td-v evo and 4x2GB f3-10666cl9-2gbnq.
I've been in a lot of trouble in finding right settings for this setup and went trough a lot of bsods in windows, so decided to try some settings and found some info in internet and tried them and it works great for more than 3 months now. I've done a lot of tests with memtest for each setting so it took about a week to check every possible combination. So I decided to share the settings I found best for this combo.
1CLK=1/ (667*10^6)=1.49*(10^-9)=1.49ns
MemoryClock Mode Manual
Memclock Value 667
DRAM Timing Mode Both
TCL 13.41ns = 9 CLK
TRCD 13.41ns = 9 CLK
TRP 13.41ns = 9 CLK
tRTP 7.5ns = 5 CLK
TRAS 35.76ns = 24 CLK
TRC 49.5ns = 33 CLK
tWR 15ns = 10 CLK
TRRD 6ns = 4 CLK
tRWTT0 Auto
tWRRD Auto
tWTR 7.5ns = 5 CLK
tWRWR Auto
tRDRD Auto
tRFC0 110ns
tRFC1 110ns
tRFC2 110ns
tRFC3 110ns
(TCL->tRDRD repeat all the same for the second channel)
Memory Over Voltage 1.53v
Can't find only 4 settings so I let them on Auto and it works fine.
