Randy-
this may or may not help you, but i have 4 sticks. however, i have always had 4, so dont know about 2v4 stuff...you may need to raise mch.

But one trick that i have learned for tweaking memory with this board is to
1) drop processor clock by 20-30mhz...say to 350 in your case
2) set mem frequency to the lowest possible while leaving mem ref the same
3) reboot
4) increase mem frequency 1 step at a time followed by a reboot
5) once back to desired mem frequency, bring processor clock back up.
6) tighten timings

by following this method i have been able to boot to and remain stable at 375x10 and 333/1333 6-5-5-11-50-15-15-15-15-1T (1500MHz FSB, 1500MHz mem PC-12000), now mind you that my q6700 is natively 266x10, 1066FSB...and i am still working on lowering mem timings.

also, after 1521 i was having all kinds of problems booting, so i bumped vMCH and loosened timings all the way out (but stayed with 1T Command Rate), found highest mem ref and freq i could boot to @ 266x10, started raising processor clock until BSODs or random reboots, backed off a bit, and then started working my timings back down.
