The bios does count up all the ram on when i clear the cmos, and says all 16 gigs of it pass. i also double check the ram population sequencing on the board to make sure it conforms to the table listed inside my board manual. i'ld be willing to run a ram test if i could do so before the post completion.
I'm thinking its the bios, I'm likely going to have to replace the chips, hopefully that will correct this mess, i ran out of ideas a long time ago, at least you provided something different to try. I'll let you know how that goes once i get the in the mail.
