ok, maybe im doing something wrong in troubleshooting this? Been posting and testing for 2 full days now, maybe AG or RG would have the solution?

I don't understand how adjusting BIOS setting will fix this. If the memory is on the official DFI list of supported dual channel memory, how could default settings (after cmos clear) on the official DFI BIOSes not work?

 

I mentioned in my thread that most of the time we see these problems, an opteron is the CPU. RGone noted that a few other members were having troubles getting dual channel to work on their mobo's, but an a64 worked fine. Does anyone else have any evidence that would hold the opteron at fault?

could be that opteron can cause some problems, i couldnt say since i have a socket 939, but as an example of settings, this board main advantage is the ram settings, so it dosen't necessarily default to best settings that work for all rams setups recommended, for example, two sticks will require more power than one, so need to increase voltage from default, also bank interleave and all the ram timmings, and could be settings required for dual channel, wich is what i am waiting for someone to come up with as incredibly enough i havent got any suggestions for ram settings after two days of posting and doing multiple all that was recomended, even the recomendations that were closer to voodoo rituals than straight to the point troubleshoot that allow to draw constructive conclusions...

where do i set spd to 1t or 2t?

[dæmon]

That option is the CPC or command per clock. It is either enabled, disabled, or auto. Enabled = 1T, disabled = 2T.

 

I am about to try these settings from the ocz forums posted by RyderOCZ for the 704-2BTA BIOS. I will post back here with the results.

update: the system can boot in single channel with two sticks(total 2gig) but not in dual channel in the orange slots, both sticks pass mem test and have been working in dual channel fine for the last few months, but they only setup that works now is the closest slots to the side of the board, one in orange one in yellow, but wont boot with two in orange, but will boot with any of the two sticks in the orange slot near the edge.

Same deal here. Can boot in single channel with top yellow top orange but not with dual channel at all. Tried RyderOCZ's timings and still no luck.

I'm having roughly this same problem. I upgraded my CPU to an opteron 146 from an Athlon 64 3200+ venice and now I can't run in dual channel mode. I've tried different sticks of RAM too and I still get the BIOS memory error. If DFI doesn't address this issue in some way, this Infinity SLI will be the last motherboard of theirs I purchase.

is it just me or is there a BUNCH of people with the exact same problem...

yea, there used to be support for these problems, and you didnt have to do random trail and error for 3 days, my fingers are burning from switching modules around

I also can't boot with two sticks of mem. Been running the same setup for close to a year. Yesturday I get the long beeps. Take computer apart and reseat everything several times. Couldn't find the problem. Started from scratch with just one stick of mem and computer fired right up with ram in either top slot. With same module in bottom(closest to CPU) slots the computer won't boot.

The question is it the CPU or the motherboard? Since the mem controller is on the CPU it could be either. I don't have an extra socket 939 CPU to try. If it does it with a different CPU then it is the board.
