The system boots knoppix and windows fine, but I don't have gentoo on it (yet :) and I don't have lshw on any live cd I have... It can take PC2100, PC2700 or PC3200 though. I currently have 2x 512Mb PC3200 in it. > Then if you can find the mobo book, look at the published memory > requirements and go into the > bios, and look at the bios settings for something out of the ordinary. it is a "jumperfree" board, with overclocking options in the bios, but they're all turned off. > If you can, swap the memory with another know good system for a few days.... > Something might show up as a problem I did that. The new RAM (another PC3200) works ok, but memtest still fails at the same point (test 3). This is confusing me. the same live-cd runs memtest on my other machine (DDR2) without fail... The other funny thing about memtest is this: The info it displays about the system is a bit strange. Sometimes it shows a CPU clock of 2999MHz, sometimes 3000MHz; sometimes the RAM shows DDR398, sometimes DDR400. It's always the same for one particular run of memtest, but sometimes changes between boots. > > (Ultimately, I'm trying to diagnose a random reboot problem, which makes > > me suspicious of the memory, but I'm not sure) > > I always look at the temperature as the mobo makes it available, > or checking the temperature of the hard drive with 'hddtemp /dev/' I plotted some GPU and CPU temperatures while running some games, and they all go to a reasonable maximum and stop there. I even turned the case fans off, and they don't go higher. The "random reboot" problem is now a "won't boot" problem! I put the original RAM back in the same slots, and now the HD's, CD's, and fans spin up, but no display appears. I hear a bios beep, and that's it. Maybe it's a MBoard issue? Maybe a video card issue? Hmmm, I don't want to replace the whole lot! > Often power supplies will run ok can then glitch causing a > reboot.

I don't have a spare. thanks, -- Iain Buchanan The Heineken Uncertainty Principle: You can never be sure how many beers you had last night. -- gentoo-user@gentoo.org mailing list
