Successful overclock fails after a month
Successful overclock fails after a month
Something interesting happened yesterday. I was happily hacking along on my overclocked Bad Axe 2 when the keyboard stopped responding. That had never happened before. The mouse still moved the pointer, but nothing else worked. I bounced over to another system and tried to ping the Bad Axe -- no response. Sigh! Just as I was about to hit the reset button, I got keyboard back. Poked around and GAH! Disk errors are logging on the root filesystem. Oh, no, Mr Bill! Nothing worked -- couldn't shutdown, couldn't reboot, I could only hit the reset switch...... (queue dramatic music) After the system POSTed, I get the ever popular "The BIOS has detected a failed boot, enter Y... blah, blah, blah" My overclock was now failing. I messed around with it for a bit, but something had caused my month-long overclock to crap out. Oh well, I set things back to their non-overclocked settings and am happily cruising along with no problems that I can see, but this strikes me as fairly weird.
Back in business
Yesterday, I gave it another go. Bumping the CPU voltage one more click did the trick. Overclocked again, and I powered it off overnight and it fired right back up again this afternoon.
The specifics:
BIOS version 2692
Room temp is 26C, CPU at idle is 40C (heatsink fan is poking along at a nice quite 1200 rpm)
system BIOS settings:
FSB to 333: 8 x 333 = 2666
CPU voltage override: 1.350 (up two clicks from default)
Enhanced power slope: enabled
Memory frequency: 667
Memory timings: 5-5-5-12
Memory voltage: 1.92
MCH/ICH voltage override: 1.525 (up 1 click)
FSB voltage override: 1.25 (up 2 clicks)

Seems okay
It seems okay now. I ran a number of tests after the first overclock: orthos for 4 hours, memtest86+ overnight, cpuburn (x2) for several hours. I'm mainly running Gentoo on this box. So it gets a pretty good workout. I've transcoded hours of video and it hasn't hiccuped once until that one time. When it did choke it was basically idle. I was web surfing.
Maybe tomorrow night I'll fire up something CPU intensive and let it run overnight.

Stoopid OverKlok!
My spelling isn't really that bad! Anyway. the C2D overclock is gone again! I give up. Clearly this system wants to run at a normal clock rate.
