Hi all! For those who were interested, I've got preliminary results from testing my clocked libby50CT (clocked from 75MHz to 100MHz by cutting pin 15). Running 'Rain' (freeware) I'm able to keep it idling (actually, surfing which is mostly idling) for hours without it going into thermal shutdown at full power on a day the mercury climbed to 31ºC (and before I got sick and tired of it and turned the AC on). Not too bad considering it went into thermal shutdown within half an hour of switching on WITHOUT rain when the day was only some 20ºC earlier on. Indeed, when the libby is PURELY idling, the keyboard doesn't even become unusually warm (having said that, every surface is getting warm this time of year). Looks like rain is doing its job ... doesn't seem to hit performance much either, I'm decoding 320x240 MPEG1 video clips at quite a watchable framerate (I'd say at least 15fps if not faster but thats just an eyeball estimate). If I put in a 10 or 20 gig hard drive I'll be able to watch episodes of DarkAngel or StarGate on my libby instead of watching lecturers during lectures! (1.5 hours of battery life should last me 2x45 minute episodes, almost enough to cover a 2 hour lecture ;-) The libby has no unusual cooling (indeed, most of the time its surfing its stuck in the enhanced port replicator which would reduce heat dissipation), the only thing I HAVE done is smothered that rubber pad with heat transfer grease and put it back between the heat plate and the processor. Speaking of which, does anyone know if the temp sensor is on the processor itself or on the circuit board (perhaps under the processor), or somehow connected to or nearer to the heat plate? As for hard drive issues people have been having with clocked libbys, my only issue has been my hard drive making the odd squealing sound (its the original 770MB hard drive), I've not had any data corruption yet nor any unusual freezes. PCMCIA cards don't seem to throw a fit at all either and my battery life at full power thrash-the-hard-drive-to-death-the-whole-time, screen-on-full, processor-going-like-crazy on a new pack is about the 1.5 hour mark (WITHOUT running rain ... I had to have it near the AC vent to stop it going into thermal shutdown). Of course, if it blows up or something I'll post it, but this libby seems quite stable. Its one of the PROPER P75 libbys (NOT a P120 downclocked, I did pull off the heat plate and have a look). - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
