Set your HT to 2000MHz and keep NB at current speed.
Set the RAM to default specs in BIOS at 1.65V.
Memories of manufactures say to 1.6v, above this value, I have set starting at 1.8v with proper operation, also with latencies of 11,11,11,28, and 9,9,9,24 1T, 2T
The HT should not go to the same speed as the NB?
I use these formulas: for RAM:
DRAM Frequency = [(FSB*DRAM Ratio) / FSB Ratio]*2
(210*18.5/4)*2 = 1950MHz
But I can not run at that speed but that does not support more than 1600, since it does not start the setup.
CPU-NB Frequency (+/-200) = (CPU frequency * 2) / 3.15
3900MHz = 2476,19MHz NB
I tried with HT 2000 and 1.65v, but not stable.
