So, its just simply nto worth it? My vcore was originally set at 1.38, but i will give it a try.
O_o 1.38v is not stock voltage. uber is about right, you'd probably only need 1.2v or so.
What ram do you have? If you have 1600MHz ram and your memory multiplier is at 10, you were overclocking your RAM and that's probably causing the instability.
BCLK = 160
CPU multiplier = 21x
Memory multiplier = 10x if you have 1600MHz rated RAM (8x if you have 1333Mhz, etc)
vCore = 1.2 (Try 1.25 if 1.2 doesn't work. after it's stable, slowly lower it until you find the lowest stable setting and back off a notch or 2)
Just for reference... Most 920 D0's and 930's would run 3.2 at 1.15v-1.2v.
Turn vDroop off and Turbo Mode off.
*If none of this works, you might have to raise your IOH voltage a tad, or PLL voltage to 1.875.
