@Tyke, could you please find out the revision of your board. The random lockups that I was having was because of P1/P2 enabled. I set it to Auto and the lockups go away and you said you are not having any issues with P1/P2 enabled. P1/P2 enabled @445 FSB requires a lot of spp voltage and/or a lot of vdimm. You also said that your OCZ EB could do 1900 with 1.9. Is this with P1/P2 or without.
