the other RD option disable

NB = 1,32V
NB GLT = 0.600
Mem 1.98V, I heard P5Q have a + .10V in memory, so 1.98V gives 2.08V if a increase to 2.00V it freezes when trying to run any 3D aplication.

And some of you are posting with more than 2.10V I donīt get it
It looks like you have too many settings configured to isolate this to only the memory. Take the processor out of the equation! I would try to set as many settings to AUTO in the BIOS as possible, run on a 6 multiplier and boot into a memtest.

Try setting tRFC from 55 to AUTO on your board. Try running with 2.1v all other memory settings to AUTO with the exception of 5-5-5-15
