I just finished building a folding machine consisting of a 2.8E, IS7 mobo, 512mb Geil PC4000, 60gb Maxtor IDE drive. I am using the stock heatsink, for nowI am going to get an XP-90 next week, then the PC4000 ram will come into play. I know for a fact that this chip will run at 3.45ghz, so that is a nice boost. I also started a 2.66B on an IC7(roommates comp) which is running at 3.0ghz. These 2 new comps havent completed their WU's yet, but when they do I expect the jump quite a bit in rankingsAnyway, I still have plans for a folding farm after x-mas. I am hoping to have 6 Pentium 4's, all at 3.0ghz or higher running 24/7.
