However, I never have any problem with the machine, other than this benign occurance.. and I do tend to tax it every now and again (couple ports building, world building, mp3 encodes, the usual). Ack, can't believe I forgot to mention I'm running with soft updates enabled on both drives (and root). While I was reading this thread btw, I got another spike, and by measuring pixel widths in xload, came up with 30 pixels @ 10 seconds per pixel, or 300 seconds, or exactly 5 minutes, which seems awfully round. Re: overclocking thing: ok, people, I know it's my machine. Take a chill pill. I have a very stable CPU, a well ventilated machine, and a jumperless motherboard that makes it very easy to switch settings. However, as I have said, this machine has been rock solid (except for during a few of those sketchy 3.1 release ;) I'll go ahead and try turning off the overclocking and see if a) it affects the voltage (which does worry me a bit) b) I continue to see this load strangeness (I suspect I will) --David Bushong To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
