I have the same problem oc'd or running stock speeds... this has been with v1.5x to current 1.6 with the Blue Screen Error Message (i've never seen before except with this):
*** Hardware Malfunction
Call your hardware vendor for support
*** The system has halted***
With the earlier versions where one could select the amount of ram to test, I could get a 5 run pass if I selected a "small" amount of memory.
Intel D5400XS with 2 x QX9775's
4 x 2GB PC6400 Mushkin FBDIMM
PCP&C 850 (stand by for grief

)
Win XP Pro x64
Cooling is a little 6000btu a/c that I pipe directly into the case.
