Not Compatible: F2-6400CL4D-4GBPK

[kfn00b]

My memory doesn't seem stable in my new motherboard. Yet this memory is on the compatibility chart of my motherboard.

Every time I run Prim95 my system freezes up within 5hrs and my CPU is not overclocked.

What settings do you recommend that I run this ram in order to obtain stability?

RAM: F2-6400CL4D-4GBPK
MOTHRBOARD: DFI LP JR GF9400-T2RS

I have tried 4-4-4-12 @ 2.1v as well as 5-5-5-15 @2.1v. Both settings are not stable, yet there are some more advanced settings like tRRD, tRC, tWR, tWTR and tREF that I would like to get some recommendations for.

Here are my most critical bios settings. Please let me know if I should modify anything.






Thank You

For tREF I only have these values.

tREF: Auto, 7.8uS and 3.9uS

For the others...

tRRD: Auto, 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
tRC: Auto, 1-31
tWR: Auto,1,2,3,4,5,6
tWTR: Auto, 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
tREF: Auto, 7.8uS and 3.9uS






Do you have any other ideas?

or you could try to adjust HT voltage to 1.4v to see if it works
or you may try to test with only one stick
if there is still problem with one stick, it's possible that this motherboard is not able to run at CL4 stably
thanks
