    Well you would need higher voltage to run your ram at it's best of course, even at lower speeds then stock in order to tighten timings you may need to run the ram at it's full spec voltage, or even a little more

    Here is how you would tighten up timings, raise your voltage a bit first. Then see what the lowest tRD (Static Tread Value) you can set, with the other timings still high/loose. Then move onto the others in this order tRFC, tRRD, tRTP, tWR, tWTR

    You could also try Extreme Performance Enhance first, but you would likely need more ram voltage then stock and looser timings to start with. Possibly higher MCH Voltage as well, which also would apply as you try to lower tRD with the settings/methods listed above.

    tRD of 8 at 400+ FSB on the B Strap is likely as low as you can go, and you may even need to use 9 to tighten up the other timings. You would have more headroom with timings on the D Multi's (Such as 2.66D) at 400+ FSB, of course D does require a higher tRD then B though so you may want to stick it out with B first or make two BIOS profiles to test each way

    Okay, I added a bit of voltage and tried the lower time settings, I think these look pretty good. Memtest passed after 6hours or so of running, I'm trying the burnin tests now. I figured these voltages are safe since they fall into the ranges you gave me (Please let me know if I'm wrong :)).

    I might try the D strap at some later time. These settings seem very stable, so I'll probably stick with them (unless they become unstable for some reason).

    Thanks for all your help!!!!
