I recently got myself a uATX SoA motherboard that supported multiplier adjustment etc etc. It's an ASRock k7s41. I have an XP-M 2500+ from the last lan (thanks again!) which I am told clocks rather nicely, but I'm struggling, mainly due to the motherboard I think.
The board has two sets of jumpers, one for the fsb and one for the multiplier (6x-->24x) although the fsb is also adjustable from within the bios manually in ~1MHz steps. Problem is although I can set the fsb jumpers and they work fine, the multiplier jumpers are having no effect and the cpu is stuck on a 14x multiplier. It boots fine at 133MHz and occasionally manages a partial POST at 166MHz, but as the multi is stuck at 14 (no matter what I do to the jumpers it seems!) I'm not having much luck.
I did a quick google and it seems that although the multiplier adjustment works, it only works for unlocked desktop cpus, not mobile cpus? Something to do with possibly adjusting the BP_FID instead of the FID which I didn't really follow...
I thought I might be able to try a software overclock ... using CrystalCPU or something?
