Hi all,
So with the chiller on the XP 2600-M I have had great results. So far I am able to get it to around 2.8 ghz using a variety of multi/fsb variations. I did the wire trick to unlock the higher Multi (13 and up). With the chiller the temps are around 19 C at idle and up to 23 under load. So far I am very pleased. My FSB has still been touchy despite cooling the mosfets. I also put a fan blowing air over the heatsink for the fets and the NB. I was able to get up to 215 x 13. I like that the best and think I will stick with it. As for stability testing I still need to run prime 95, but I have been able to play all my games and get through 3d mark. I always find it interesting to see how altering my mobo/chip speed increases my score. Last night I got a 19,600 in 2001. This is without any Vid Card OC. Can't wait till I get that thing cooler. (Radeon 9800 XT / 256)
I was also able to run 200 x 14 but could not boot with a FSB above 203. It is interesting to see how one digit makes the difference between stability and instability. If I wanted to go higher at this point I would need to do a volt mod as I am at 1.825 volts at the moment.

I really like this chip, it makes all that cash I spent on cooling seem worth while.
