Yes I did try that before, core-accel-core but today I received my second accel card and insert it exactly like it should be core-accel-accel...result same problem, i'm gonna try to swap the two accel position, but just so you know slot 5 core, slot 6 accel, slot 7 accel, if that still doesn't work then I will try on my second xw8400 and see perhaps that's a hardware problem, perhaps the motherboard is starting to give away, because it seem that anything i put in slot 7 doesn't work, is there something to change in the bios, perhaps that can also be a problem. my bios is v.2.38
