What does this mean?

"expand Xgroup codes locating in physical address 1000:0"

its post code 0h1. I get it whenever I try to use my corsair xms 3200c2 (rev1.1)... I know the memory is fine (have another test board), and I know the board is fine (have other memory)... I tried going into bios and setting very lax 3-4-4-7 for this cas2 ram. Also upped the voltage, but it still won't post.

Any suggestion, and if not those, can you at least tell me what Xgroup is? I see it in reference to fan control or something like that on yahoo (no really good explanation).

lots of ppl have had trouble running any ram at cas 3 on the 8rda, try setting it to 2 or 2.5 and see if that helps. also try changing the dimm slot you are using.
