Trying to stabilize 2166 FCLK and I'm not sure what other dials I can tinker with. Linnpack shows some instability (see link below)

VSOC is at 1.27 which seems to be my lowest stable setting (after doing some y-cruncher VT3/FFTv4 testing while running FurMark).

VDDG CCD and IOD are set to 950mv

Any thoughts?
