rtgr8 Posted October 13, 2007 Share Posted October 13, 2007 I just put this new sys together and can't get dual channel to work. I have 2 1 gig sticks Corsair XMS2-6400 800mhz 5-5-5-12. they both work in the CHAN A slots either by themselves or together. but when i put one in the CHAN A 1 and CHANB 1 for dual channel, it wont post. Ive tried every combination possible including just one or both in CHANB slots, which wont post at all either with one or both. I called MSI support and they said to adjust the timings in bios which i tried and it didnt change. not sure if im doing that right tho. i changed those as follows: CAS# LATENCY = 5 RAS# TO CAS#DELAY = 5 RAS# PRECHARGE = 5 RAS# ACTIVATE TO PRECHARGE = 12 then by default trfc = 38 twr = 12 twtr = 12 trrd = 12 trtp = 12 am i setting something incorrectly or do i just have bad mem slots on chanb?

Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 If both modules will run and pass http://www.memtest.org one up but the system will not post when in dual channel that would suggest a problem with the MB or BIOS and I would suggest talking to the MB maker.
