Hey Terry! YMMK, as another poster said different systems act differently I have used a Powerlogix G3 ZIF and ZForce carrier for about 1.5 years now. One of the two pieces has 512K of L2 cache. It has been in a PM 7200, 7600 and now a 8600. These two items are no longer supported by Powerlogix as they can not get faster chips, reasonably. Theoretically, this combo can reach 500 Mhz and a faster bus speed. 350 is the ceiling _my Macs_ have found. It runs stable below the 155 F range, but beyond that, no. I did have an extra fan installed in the 7600. The 8600 comes with a pusher and a puller. It has been stable up to 350 MHz and 175 MHz on the cache. Beyond that it is not stable. I think that I have bumped up the bus speed and gotten away with a little bit more, in the past. When I put it into the 8600 I was having fits trying to get it to boot. Even at lower speeds. There was some weird conflict, that was preventing it to boot or even chime. I could not even boot with the Extensions off. I had to pull the card and reinstall a 200Mhz Apple card, change the extensions and try again. I had even pulled all non-stock PCI cards and drives, and all SCSI, USB & FW connections. Finally I installed Sonnets software and all of the conflicts went away. Tried it with my old extension set, except the Powerlogix, and it was fine. Still would not boot above 350 Mhz. I switched away from the Powerlogix Profiler before, because when monitoring the chip's temperature, only Powerlogix caused the temp to jump 8F by just starting up, and the least accurate. I wanted to it to try as stock a set up as possible and to see if I could get sustain higher speeds. It is a nice speed bump for the 8600/200 mobo. The 8600/250 and 300 used a different mobo. HTH, (& promise no more Volvo stories. < Off list story.)
