Before changing dram freq.,some things should be set manually.

restart @ desktop / delete to bios tweaker
keyboard arrow down to Ai oc tuner , its hilighted white
press enter /select manual /press enter/ F10

restart @ desktop / delete to bios tweaker
dram bus for these dram is 1.65v, set it to 1.65 /F10

your ram>

restart @ desktop / delete to bios tweaker
QPI/DRAM core to 1.25~1.26 / F10

* always keep qpi/dram core voltage within .5v (1/2v) of dram bus volts to prevent damage.
1.65 - 1.25 = .4v diff, within .5v envelope.

restart @ desktop / delete to bios tweaker
scroll to dram freq / press enter /select closest freq to 1600.
MUST verify UCLK freq. is 2 times , with your i950 if I recall correctly.
basically when you change dram freq and press enter uclk freq will follow directly.
so verify it ex: if dram you choose is 1582MHz , uclk freq needs to be 3164

If your pc locks/no post etc , del to bios press F5 / F10, or reset cmos(info in user manual)
