    Yeppers! I had bought the d945GCLF a couple of weeks ago but hadn't put it in yet, so when I saw that the dual core had come out I sold it - now I just need to find somewhere that stocks it already !

    Ive found the intel essential series boards to have very picky ide controllers.

    Some of my CF-IDE adapters work some dont. Some 2.5"-3." pata adapters work some dont. So far havent found a pattern to it. It would be good to get to the bottom of this.

    Hi:

    I have readed a lot of reviews about D945GCLF.

    I have some questions that I think are no clear

    1) The power consuption is very variable in the reviews. What is the REAL consumtion of the mother (without any SATA ,IDE, USB or PCI attached???)

    2) There are a power connector for 12V P4 (the 4 pins near the CPU). What happen if are not used?

    I measured actual 12 volt dc draw (of the dual core version) here:
    Intel D945GCLF2 Dual-Core Atom

    Because atom draws so little the actual power draw on the 12v 2x2 conecter is very little. Nonetheless its still required, a computer with no power to the CPU is no computer.

    See
    http://download.intel.com/support/mo...35968001us.pdf

    0.8 amps total on 12 volt. Most power is used on 5 volt rail, upwards of 8 amps.

    Yes, I have readed the intel pdf, and speak about 7A BUT with one hard disk drive, one optical drive, and all board peripherals enabled
    The minimum recommended power supply is 75 W.

    The following table said that use [email protected] and [email protected] this is arount 45W


    This numbers are consistent with your comment ! TXS

    PD: the 8A is a peak or is consistent? (an LM 338 can regulate 5A with a peak of 7A)

    Ive just had a protracted email dialog with my supplier and they are certifying the procase/morex cs-3688 case as atom friendly (D945gclf2). The DC board in this chasis is a morex sh-6080 with specs:
    3.3V 5A
    5V 5A
    12V 2.5A
    more suited to EPIA stuff.

    I think so long as you dont go plugging heaps of USB stuff in it should squeak in. But personally ill be upgrading the board to morexs 150 version which is rates at 8 amps on the 5 volt rail.

    The good thing about the dual core atom board is the north bridge HSF has been reduced in height from 45mm to 30mm and its this factor that makes this case work at all.

    I have 2 D945GCLF , not D945GCLF2. I'm not sure about the difference in power consuption

    Does anyone know if this board will work with an M1-ATX PSU? only concerned because of the low 12V rail on the M1, on the computer I have a DVD drive which really I never even use and may just ditch it and use a USB when/if I need it, i'd be getting an SSD drive, I do currently have a geforce MX4000 video card there but that's stricktly so I can get 800x480, so if with the updated bios this can do that res then i'll be ditching that, and there's my GPS reciver, touchscreen, and an occation thumb drive plugged into the USB ports, don't have any case fans atm with my MII10lk board, and it's deen fine, not sure if ones needed with this M/B but really I can just hook that up to the car's power instead to not add more 12V load to the PSU.

    If you don't power the four-pin connector, the motherboard will not operate at all. I have, uh, tested this.

    Regarding power consumption, I have measured this in a careful way.

    My computer uses the D945GCLF, with a 1-gig DDR2 memory module, a full-time fan for the chipset (powered from the 12V rail), a case fan plugged into the system fan header on the mobo, a 2.5" 120G SATA HDD, an IDE-interface compact flash adapter, a 10.4" touchscreen display, a "slim" CD/DVD combo drive, keyboard, mouse, a Garmin USB GPS puck, and a Belkin USB wireless Ethernet interface. All devices supported by the chipset are enabled. The computer draws 34 watts continuously at 13.6 volts from a regulated power supply. When spinning up a DVD or CD at full speed, the consumption goes to 40 watts continuous, maybe occasionally peaking to 41 watts. I am not guessing here, these are careful measurements made with the right equipment.

    The power supply is an M2-ATX-HV, which at this input voltage is about 98% efficient.

    I'm running the monitor from the 12-volt rail--it's plugged into an HDD power connector.

    I have not run it without the drive, but without the monitor, the USB wireless interface, and without a CD in the combo drive, the consumption is about 20 watts. The fans together consume no more than a watt or two.

    Those who are using up 50-75 watts with this motherboard must be running some big honking 3.5" hard disks, or really hammering the processor and chipset. My tests were run with XP Professional (with nothing done to reduce consumption), Garmin Mobile PC running, and playing Solitaire (that touchscreen makes Solitaire a lot more fun, heh, heh). I get the same power consumption no matter what OS I run, and I can boot this box up in either XP, Ubuntu, or MS-DOS.

    Rickd:

    TXS!!! with this values I can finish my PSU (in Argentina a DC-DC PSU is impossible to find! I can construct one of these for 50W for less of U$S50)
