WEll..look what we have here
Me, a 2100+ tbred-b at 2800+ 2.3ghz
First, check your core, palomino or tbred, and if u have to unlock it (if an Nforce2 motherboard, it'll unlock tbred's automatically)
and then make sure u have a good heat sink
and then check your power supply and then your memory.
ddr333 runs at 166fsb but your current setting might be 133 x 11.5 right???
well...if so...try boosting up the multiplier, to 12, 12.5
and check your ram, ddr266 runs at 133fsb (133x11.5) get it?
and slowly boost it up, both multiplier and fsb
and boost up voltage of cpu and ram slowly too, if needed
and check if windows is stable, using software such as sissandra, and if blue screens or random restarts, then yea, it's not stable.
so try.
if palomino, look around for unlocking guides.
