Guest RJK Posted August 28, 2008 Posted August 28, 2008 ....also seperateley posted in hardware i.e. cross posted to wrong NG A few weeks ago I switched on "Intel Speedstep" in my "old" main PC's bios, and selected XP's "Mininal Power Management" scheme, and tweaked other settings for ages to find out what the best settings were, to get the most of this "power saving" feature, closely watching various motherboard frequencies with CPU-Z, and Hot CPU Tester Pro etc. to keep an eye on what was going on with motherboard frequencies. (Asrock Conroe865pe|D935|4xCorsair512mbPC3200/ddr400|3 hard disks|Seasonic 430wSII psu|2xDVD drives|card reader etc.) And also around that time, for my 2nd PC, I downloaded AMD's dualcoreoptimizer.exe, processordriver.exe, and powermonitor.exe, and installed them, and switched on its' "Cool'n'Quiet" feature, and selected XP's "Mininal Power Management" scheme, and tried various bios configurations to determine which was the "best" set-up. i.e. certain settings have to be on "Auto" or cpu will not drop to a lower frequency whilst idling. (Asrock AliveNF6G|6000 2x3.0ghz|2x512mbPC2-5300|2 hds'|1xDVD drives|card reader|Seasonic 380wSII | etc, ....and tonight, just out of interest, I plugged my TCM mains power "guage" in (UK 240 volts btw), and my {AMD PC+monitor+11 watt desklamp}, into it, to see what they were using, and was ATONISHED to note the difference in mains power consumption, between "idling" with cpu at 1ghz, and making the thing do a lot of work i.e. cpu working at 3ghz - 73 watts whilst cpu idling, and 131 watts with cpu under load !!! Surely that's good, ...but, also a little ridiculous ? :-) regards, Richard ps before someone gets clever - that cheap plug in "mains power guage" is pretty accurate i.e. current drawn in amps matches a pretty accurate ammeter.
Guest Anteaus Posted August 29, 2008 Posted August 29, 2008 RE: OT: Bios / power saving features... It is my experience that manufacturers of all electronic devices (for some unknown reason) overstate the power usage by a very large margin. Thus, a PC with a "500W" rating doesn't use anything like that. In your case 150W or less even without processor-idling mode working, less still with it working.

Guest RJK Posted August 29, 2008 Posted August 29, 2008 Re: OT: Bios / power saving features... Hi, You're right about the "overstating," ...there is a simple formula somewhere in the rails/amps sticker usually on the side of psu's i.e. amps are all rounded up and averaged out to give a rating somehow, ...read about it a long time ago - can't remember even half of it !! ....rely on Antec.com's wattage calculator nowadays :-) regards, Richard "Anteaus" <Anteaus@discussions.microsoft.com> wrote in message news:41185A43-25CF-4002-BB96-8B5B58E6D65C@microsoft.com... > It is my experience that manufacturers of all electronic devices (for some > unknown reason) overstate the power usage by a very large margin.

But what's specified on the side is the *rated* (maximum) current, not the actual current used, which depends on the current drawn by the computer. The same basic comment applies to the power RATING of the supply, vs the actual power used by the supply, which is generally much less. > > > "Anteaus" <Anteaus@discussions.microsoft.com> wrote in message > news:41185A43-25CF-4002-BB96-8B5B58E6D65C@microsoft.com... >> It is my experience that manufacturers of all electronic devices (for >> some >> unknown reason) overstate the power usage by a very large margin.
