I gave up on this awhile ago after following the directions in the config sticky thread but basically computer wont even boot if i run dual channel but works with sticks in 1/3 or 2/4
and now i just installed amd overdrive to see what it has the settings as in there and it says something like
dram frequence 400.mhz
fsb:dram 1:2
CL 6
trcd 6
trp 6
tras 15
trc 20
cr 1T

maybe i have a bad mobo i dunno

Motherboard, CPU, BIOS revision? If Intel use XMP, if AMD you have to set up manually or accept what is prob 1066 or 1333 defaults

m4a785TD-v Evo
rev x.0x? i dunno or 00

bios says
version 2105

i tried to follow the thread for the AMD set up and it still made my computer mess up before with dual channel, now i can't even get it to start if i try to run in dual channel

You've got the latest BIOS which is good, what CPU are you running, generally for 1600 sticks you'll want a 965 or better. If your CPU can't carry 1600 might set to 1333 and at 8-8-8-24, 2N, 1.5
