    Got bored yesterday, so I ran checked out the power consumption of my X3360 system for ****s and giggles.

    Powered Hardware Details:
    Intel X3360 (C1 stepping) @ 8.5x400=3.40 GHz
     266/667 MHz Strap  CPU Vcc=1.12500
     NB Core=1.370      CPU VTT=1.310
    DFI LT P35-TR2 (no modifications)
    eVGA 8800 GTSG92 512 meg 
     (770/1,923/2,000 MHz : Core/Shader/Memory)
    Corsair Dominator DDR2-1066 (TWIN2X4096-8500C5DF)
     2x 2Gb @ 5-5-5-15 (performance level 6) @ 1,000 MHz (4:5) @ 2.100V
    Corsair HX620
    2x HDs (seagates, one a 10th generation and the other an 11th)
    1x DVDROM
    4x120 mm Tricool fans (came with the p182 case) all on low
    1x120 mm S-Flex SFF21F (1600 RPM) on the HS
    1x40 mm silent fan on the NB
    That's it... no other hardware (speakers, monitor, etc.) was in the loop.

    Kill-a-Watt Readings
    Idle (with speedstep active) - 137 W
    Load (prime95 v25.6 small FFT) - 213 W
    Load (prime95 v25.6 large FFT) - 216 W
    Load (prime95 v25.6 blend) - 210 W
    Playing Crysis - 237-241 W
    x264 encode - 197 W
    Standby - 0 W

    No real point to this post beyond just trivial information! It is interesting to me that the large FFTs consistently read 3-4 watts higher than the small ones did which is inline with the software's description of the large FFTs as generating the max heat/power consumption. Here is the similar analysis of my older Q6600-based system, but there are too many changes (MB, settings, video board, memory, etc.) for a "which processor is more power efficient" comparison.

    What is little bit crazy is that both systems draw the same while idle, and even @ 3.4 GHz, and faster memory, the X3360-based system uses less wattage on p95.

    Thats actually pretty cool man and I have a pin mod thread to start soon for my Northwood Celeron 2.6. I ran the x264hd benchmark @ default for reference and its scary lol :D

    Will incude that for reference if ya want but got this Celeron doing some cool stuff with 2 pin mods :mrgreen:

    You figures are very similar to mine. :mrgreen:

    graysky, you also used a UPS to test?

    Man, I feel like getting one myself. :mrgreen:

    He used "kill-a-watt", an external power usage meter plug directly to power source.

    Yep. Linky. For $24, you can't go wrong. Plus, if you do buy one, you'll find yourself measuring all kinds of shit around your house. For example:

    XP3200+ based system
    Idle 78 W
    Load 97 W

    XP2400+ based systm
    Idle 122 W (athcool = off)
    Idle 76 W (athcool = on)

    Q6600 @ 8x333 @ 1.1500 V
    Idle 128 W
    Load 195 W (Prime95 small FFT)
    Standby 7 W
    UT3 178-195 W

    Q6600 @ 9x333 @ 1.2625 V
    Idle 137 W
    Load 231 W (Prime95 small FFT)

    Viewsonic G90f 19" monitor - 52 W
    TV 27"- 90 W
    My network router and switch - 7 W
    The xmas light my wife puts up each year - 310 W
    Toaster - 914 W
    Paper shredder - 38 W
    Pedestal fan on low - 36 W
    " " " medium - 39 W
    " " " high - 45 W

    Now that is REALLY useful! Argghhh.. Too bad zy is already on the way home soon. Otherwise, I can get him to bring it back for me. :wall: :wall:
