I built a box for a friend on a budget and went for the 450, which another friend had managed to screw up to about 600 with a huge heatsink and fan/s. These were Gigabyte mobos with 100MHz FSB - I see you've been pointed to wikipedia re that - and PC133 RAM, and both 'mine' are still rocking 8 years on, running standard spec .. I'm still rather awed to hear 700MHz though, especially when you say: > pretty sure this was never over clocked. It was the secretaries > computer of the church I attend.

You'll need to find out the motherboard make/model and google up its manual to have any chance of resetting bus speed / clock divider and such. There's another whole trip about setting the cpu core voltage for different speeds; overclocking these beasts involved black magic to which whole websites were/are fanatically dedicated, gamer folks mostly. > > If you really are running it at 700MHz (at what bus speed setting?) then > > I'd treat it to a new heat sink with fresh thermal paste and a BIG fan. > > Ok, sounds good. I'll see what I can find for this CPU. Seeing you'll want to replace the no doubt well dried out thermal paste anyway, K6-2s are clearly marked with notional speed and model numbers. > > And sure it's best to run matched-speed memory.

I learned quite a bit on the "Sig > 11" links given earlier. This is drifting well past getting FreeBSD to behave under load on it, but I googled "AMD K6 wait states" and got heaps of hits, including the above. Basically, wait states delay the processor long enough to read or write to comparatively slow memory devices; better to wait than burn. You mentioned later trying some 100MHz memory, but you'll either need a slower bus speed than 100MHz (or more / some wait states) for that, and would be better off finding more PC133 RAM. Dumpster diving, anyone? :) Cheers, Ian _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
