I tried overclocking it this afternoon, but ran into a bit of a snag. I've got an ASUS P/I-P65UP5 with the C-P6ND CPU card. The manual, and the stuff on the ASUS web site only have the settings to set the CPU to 2.5x and 3.0x the bus speed. Does anyone know what the jumper settings are for the C-P6ND card to get it to go to 3.5x or 4.0x the bus speed? The manual says: JP13 JP14 JP15 JP16 mult. ---- ---- ---- ---- 1 0 1 1 2.5x 1 1 0 1 3.0x (for the settings, see: http://www.asus.com/products/techref/mb/p65up5-tech.stm for the full manual: ftp://ftp.asus.com.tw/pub/ASUS/Manual/pup5-142.pdf for the C-P6ND manual: ftp://ftp.asus.com.tw/pub/ASUS/Manual/cp6nd122.pdf or: ftp://ftp.leo.org/pub/comp/devices/asus/Manual/cp6nd122.pdf for the Technical reference: http://www.asus.com.tw/Products/TECHREF/P6/p65up5-p6nd/p65up5-p6nd.html ) From my experimentation: JP13 JP14 JP15 JP16 mult. speed notes ---- ---- ---- ---- ----- ----- ----- 1 1 1 0 2.0x 133MHz (1) 0 1 1 1 ??? 80MHz (2) 1 1 1 1 2.0x 133MHz (1) 1 0 0 1 ? 225MHz (3) (1) Both times, the BIOS reported that the CPUs were running at 133MHz, doing performance test confirmed this. (2) The machine only came up once, and then very slowly. The BIOS reported 80MHz, and it didn't even get to the SCSI controller BIOS... (3) The BIOS reported 225MHz. I got as far as the SMP kernel boot, and the machine paniced towards the end of the kernel boot. Anyway, after 4 tries, I got sick of fiddling, and put the machine back to 200MHz. I looked at sysdoc.pair.com, and couldn't find anyone who has reported overclocking CPUs with the board I have. If anyone knows the jumper settings to get to 3.5x or 4.0x the bus speed, I'd appreciate it. Also, I assume everyone else is sort of 'spinning their wheels' as far as the RC5 contest goes. The stats page: http://zero.genx.net/bill/summary.html shows 0 hosts participating in the last 3 hours. It looks like they probably shut the server down. If someone had SYN-flooded it, *some* results would most likely get through. Ken -- Kenneth Merry ken@r74h25.res.gatech.edu Disclaimer: I don't speak for GTRI, GT, or Elvis.
