My understanding is that the above numbers are....
1. CAS Latency http://en.wikipedia.org/wiki/CAS_latency (CAS)
2. RAS-CAS Delay (tRCD)
3. RAS-Precharge (tRP)
4. Active-Precharge (tRAS)
5. Command Rate
A couple of the options on the "DRAM TIMING CONTROL" column in the Bios, I am still unclear what they are
Screen shots of the area in question....
I can match up #1-3 and I think #5 of the above memory settings on the Bios settings. I am unsure of #4. Does #4 Active-Precharge (tRAS) correspond to "RAS Active Time" on the Bios menu?
Does #5 Command Rate correspond to the "DRAM Command Rate" ?
The screen shots with the columns "2nd Information" and "3rd Information"......I am also unclear what they are for?
i hate to post before totally going through the forums but this is so similar to my problem
my bios ga-ma790fx-ds5
i think mine has one or more settings then Nytmare so what helps him might not help me
its 5-5-5-18
OCZ2G8004GK
OCZ Gold 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory
newegg sent the wrong ram rawr
i realize i can change the top 4 settings
but the 6 settings below those dont have a auto like Nytmare so i cant even do those till i figure out the bottom 6 cause im afraid of damageing the ram
another thing my mobo is real touchy just changeing the boot priority can make it boot to a known good option in the cmos settings so then i gotta change the boot priority again till it sticks. cause of this i havent been able to do much to the ram timings. but i think if i had some help it would work
cas 5
ras to cas r/w delay 5
row precharge time 5
min ras active time 18
comand timing 3
twtr comand delay 5
write recovery time 5
precharge time 5
row cycle time 18
ras to ras delay 3
is that right?:EDIT:NOOOO its not. i couldnt even set the comand timing to three its only got 1t , or 2t ++++ it dint boot and beeped an error

1. your row refresh is 56? or close to that if your on ddr2-800 settings that should be like 25 or around there
2. i got mine to stick useing your method i just put the top 4 values in and went with that( not sure if its stable though )im hunting a ram stability tester now
i think your fine just try and drop that row cycle time down and get a tester to test the stability if its not stable go with another setting
bought some 1066 gskill 5-5-5-15 2.0-2.1v tried that ram unstable as heck. Y phenoms suck go intel core 2 quad.
ill post pics of the settings so you can see what they change to when i put it as (old ram)5-5-5-18 ddr2-800 2.0v
