hello, system: Gigabyte ga-k8n ultra-9 AMD 4000+ 939 single core 2.4 Ghz 1 GB Ocz low latency 2-3-2-5 RAM Asus Nvidia GeForce EN-6800 pci-x video WD 2500JD Sata drive (JBOD on SiI 3114) SuSE 9.3 x86_64, 2.6.11.4-21.9-default kernel I ran for almost 2 months with no serious mishaps. Within the past week I had 2 times where scores of journal replays were triggered: lost power during lightning and a failed overclock setting wherein SuSE froze during bootup. SuSE managed to recover in the first case, but the bad overclock was too much -- the reiserfs was corrupted. No effort to repair the install helped. I went ahead and reinstalled with a safer, more careful overclock. Normally when I try a new overclock setting, I'm very careful and boot into memtest86 (v. 1.65) before I get to the Grub loader. Is this good enough, or is overclocking asking for trouble? If memtest86 shows errors I start over with cntrl-alt-delete and go back into the bios. My current overclock CPU freq.=216 -> DDR 433 RAM freqz=200 ( 1/1 ratio) Dram relaxed as 2.5-3-3-5 CPU voltage 1.4->1.425 volts this gives 2.59 Ghz, 5.25 Ghz/s bandwidth With the above oc, Apps load noticably faster. memtest86 predicts the numbers quite well before I get to WinXP and test with Sandra. Except for my collasol error, this is a dream machine. I restored from a BootitNG image. regards, tlviewer __________________________________ Yahoo!
