most likely(in general situation for RAM timings under normal voltage usage) here is the setting over 900:
CL:4
Trtc: 4(or TRCD)
TRP: 3
TRAS: 4~8
RMS (only in 975x):7.8 mu-s or 15.6 mu-s
subtimings:
Page Close idle Timer: 16t
TRFC: 900~1000 for 25~30; over ddr1000~1066: 30~38
Read delay: you can try 6 first, but I am pretty sure that you need 7 for stable result in 32m calculation
write to precharge command: normally 900 can be 10 or 11, over ddr1000 you will need 11~13
write to read command: definitely 10~11
read-write turn around: 7
write read turn around: 4~5
read to precharge: 4 under dr 1000,
hope this helps
