I had a similar frustration with my trusty old P120 laptop once first-time LL tests exponents started getting around 7M and more. I adopted the "amphetamine drip" solution: removed the keyboard from the laptop, slapped an extra heatsink and 12VDC cooling fan on top of the alu. plate sitting atop the CPU, fiddled with the clock multiplier jumper settings, and since then it's been running stably at 180MHz. It isn't exactly pretty, but I've found a separate full-sized PS/2 keyboard easier to use anyway, and being able to do a 9M-range exponent in 3.5 months rather than 5 is nice. If i do need to go mobile (which is infrequent, it takes only a few minutes to restore the original configuration and turn the clock back down to 120MHz. Of course, it's running Win95, so I don't have to deal with the Linux client, although others seem to have done so without too much pain. -Ernst _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
