Idle powerusage 6200 vs. 8400
Some time ago i saw an article stating that Geforce 8400 used less power
when idle than 6200. I can't seem to find the source anymore. So i brought a no-name 8400 GS a couple of weeks ago. The computer i use the card is always turned on, but rarely used for any gaming. Anyway, the card runs really hot, even when it's not doing anything besides showing a 2D desktop. Is it a possible driver issue? I use the latest binary Linux driver from Nvidia. Does anyone know where i can compare how much power the two card in question should use? -- Lasse Jensen [fafler at g mail dot com] Linux, the choice of a GNU generation. |

You might want to look into the nVida controls for mobile GeForce 8X00 video adapters. My notebook has a GeForce 8400M GS and nVidia drivers that have the equivalent of Intel 'Speed-Step'; three different sets of clock rates for 2D, light 3D, and heavy 3D requirements. But numbers are important. A C-7 candelabra base 'traditional' Christmas tree lamp consumes only 7 1/2 Watts, but you wouldn't want to hold one for very long; showing the importance of the cooling solution. Since your video card has a passive cooler, then 'really hot' may not mean much in the way of power consumption. Especially if your case has minimal air flow. You might find a non-contact thermometer useful for getting numbers. Harbor Freight has a non-contact infrared digital thermometer for ~ $3 US; and throws in hold peak and stopwatch functions. As for electrical power expense, the GeForce 8400 GS @ 38 Watts peak consumption would cost, in Atlanta, Georgia, only ~ $11 US for 38 Watts X 10 hours X 365 days X $0.08/ KWH (and that in a location where less than 30% of electrical power is produced with other than fossil fuels.) Any monitor you use will consume much more electrical power.

You can loan framed fine-art reproductions from my local public library and I thought that unusual and cultural, but your library has geek gadgets for loan?
