overclocking an Athlon XP1900

[dirkpitt1]

I need some advice from you experienced overclockers. I have an MSI KT3 Ultra, 256mb generic(I know, I know!!),unlocked athlon xp1900,gf3-200 setup. Currently the fsb is at 166, and the processor is at 10x166. I can find no option for locking the agp/pci to 66/33. Any advice on turning up the heat a little? My 3dmark scores are a little dissappointing, around 7950 without overclocking the card, and at about 8050 with overclocking the card to 200core,440 mem. Temps are great at about 35 degrees idle, 39 under load. Any help is greatly appreciated!

Dirk I don't know if this can help ya, but when I bought a 1900+ I could only overclock it to 146FSB locked with extremly good cooling. I put a 1600+ on the same setup and ran at 176fsb rock solid. I even tried another 1900+ with no more improvement. My full load temps are 38c at 1.92v. If you memory and MB is capped then just raise the multipler till you CPU temps are in the range you like them. My 2 cents.

166 fsb sounds pretty good for that cpu

that board has no option for locking pci/agp bus in spec (afaik, only the nforce2 has such a feature for amd)

what speed is the ram rated to?
if its 166, odds are it probably will go a bit over that, and a little out of spec pci bus wont hurt much
if it craps out no matter what voltage you use on the ram and cpu, only other option is to up the mult
it wont give too much of an overall system boost, but it will give a cpu boost which is better than nothing in the mind of an ocer
