A Huh, that idea would seem to match what the corsair blurb is saying. [ I was adding it to my earlier post as you posted] Good luck.

This is for the Supermicro X7DA8 motherboard?
Can't find info to support this about the northbridge stepping [which doesn't mean it isn't so]. What I am finding suggests it may be the motherboard revision needs to be 2.0+ and latest bios ? how does that compare with what you have ?

You are right I think, Here 'tis ;) at http://ftp.supermicro.com/support/faqs/faq.cfm?faq=6423

I have one of your X7DA8 board that I bought in August 2006. I would like to use quad core CPUs on this machine. I see your website indicates that quad core CPUs are supported on this board. Can I just buy quad core CPU and use it on this board?
Answer
Running this CPU on X7 boards requires G1 stepping of Memory controller on the motherboard. This change was implement in November end after Intel released G1 stepping memory controller. So, all the boards manufactured before November would not support quad core CPU.

well i replaced the board with an X7DA3+ last night. i do not believe the seti performance has increased. I did notice in Everest it is now reporting dual channel, but with no improvements in any memory benchmarks.
i did get four more dimms of memory so I can try some benchmarks with all 8 dimms populated. I will also try the X7DA8 with two dual cores to see if the memory preformance increases.

Theory based on the Mac Pros, With 8 sticks You'll get *maybe much* more bandwidth, but higher latency, which you prefer will ultimately be up to you! good luck and enjoy :D
