I downloaded the source to that cpupowerd-0.1.2 you mentioned, and it appears that at least certain AMD models do support vids > 31: int msr_vid_to_voltage_amd(int family, int model, int vid, float *voltage) { if (vid > 31) *voltage = 1.550 - ((31 * 0.025) + ((vid - 31) * 0.0125)); else *voltage = 1...

I'm playing around with nearly the same setup. I run my server on a ASUS 690g, but same processor as you. PICO PSU 120W. Two of 3.5" SAMSUNG SATA disks, 500 and 750GB. One 3.5" HITATCHI IDE disk, 40GB. I can't go lower than 66W, measured with the same device you have, no matter what I do. Frustrati...

Do any software utilities exist for undervolting/overvolting motherboard chipsets and RAM post-boot (i.e. not relying on BIOS settings), similarly to what can be done with CPU Vcore? I guess the registers involved would be very motherboard-specific, and perhaps undocumented. I'm interested in doing ...

Upgrading from an older Samsung P-series Spinpoint (250GB) to the HD510LJ, I did notice its seeks were a bit louder than the P, but I didn't try to adjust AAM settings away from factory defaults. After mounting the drive in a Scythe SQD-1000 "sandwich", the seeks are now barely audible. Hard-mountin...

This has served as my main workstation for the past 18 months or so, running Gentoo Linux-- AMD Turion MT-37 @ 2.0 GHz/1.1Vcore (0.8Vcore @ 800MHz) MSI K8N Neo V2.0 (MS-7030) Socket 754 board 2GB DDR400 RAM EVGA GeForce 6200 AGP PC-HD5500 TV tuner & capture card (NTSC/ATSC) Samsung Spinpoint HD510LJ...

These meters are useful for more than just one-time power surveys. For instance, if you leave one in-line with your computer's AC cord after measuring typical idle/load wattage figures, it can serve as a sort of load-level indicator, showing at a glance how busy the system is, whether you might have...
