    Question GA-73PVM-S2H questions (undervolt & others)

    I was looking for a new mobo for my HTPC. I found GA-73PVM-S2H and I have a few questions:
    1) what's the power consumption of the 630i chipset in IDLE? I know it has a TDP of 17.6-18W.

    2) can the CPU voltage be set to something lower than the autodetected/standard voltage?
    I have a Pentium Dual Core E2160 which can function properly at stock frequency @ 0.912V.
    I already took a look at the manual of the motherboard and I haven't seen anything related to manually setting the Vcore. If the motherboard doesn't support this, then there's no reason for me to buy it, since this is the reason I wanted to replace a 945GC based mobo.
    3) Does it support NCQ without AHCI?
    4) How long does it take for it to detect the HDDs in AHCI mode?

    I have this mbrd on my backup machine.
    Its an ok mbrd and yes you can adjust the Vcore.
    Its more a multimedia board that doesnt really need a gx card.
    It autodetects hdd fine and my D820 is sitting happily at 3.5G on it (stock is 2.8.

    Something that isnt advertised is :
    1.It wont run ddr2 memory in dual channel mode!
    2.It has no voltage adjustment for the memory
    Current Systems:

    Asrock p67 Extreme6.............. Gigabyte EP-45 UD3 ...................... Gigabyte 73 PVM S2
    Intel i5 2500k 4.8ghz................ Intel Q8400 3.8ghz......................... Intel D820 2.8ghz
    Zalman 10x cooler.................... Coolermaster V8............................ HP cooler
    8GB Gskill ripjaw ddr3.............. 4GB Gskill PI ddr2.......................... 4GB samsung ddr2

    SOunds like a decent HTPC board. The absence of dual channel will likely make little difference.

    It's a shame you didn't get an E5200 rather than an E2160. I'm slowly gathering parts for a HTPC, and an E5200 is happy at stock speed with 1.00V. It's 45nm compared to the E2160's 65nm cut down Allendale core and has double the L2 cache, making it perfect for video encoding.

    I'm planning on running mine at 2.0GHz and as low a core voltage as possible. Add some DDR-800 @ 1.8V (probably less voltage here too) and a 1TB WD Black (the green is noticably slower, and saves only 4W), then its time to get the money together for a Lian Li PC-V351B.

    Ok, you can adjust it, but can you set it to something like ~0.9V? I mean reduce it to something lower. I'm waiting for a confirmation on this one as I haven't seen anything related to it in the manual.

    E5200 can do 2.5Ghz @ 0.912V with a TDP of ~30W or even less.
    I didn't buy the CPU now, I'm simply upgrading from an 945GC.

    The board has Vcore adjustment from 0.50V up to 1.60V. There's a good side by side comparison with it and a Simmtronics board. the following link is to a BIOS screenshot showing min and max Vcore amongst other things:

    On the core voltage :
    The cpu adjustment range on my 20008 model is
    .83125V-1.6V in increments of .00625V

    ie lowest is .83125V
    next .83750V
    next .84375V
    next .850V

    etc all the way up to 1.60V

    The chipset power consumption ive no idea on .Once again I dont like using the supplied easytune utility on it .
    Since the board is a little older you will have to use the gigabyte <cntrl+F1> key combo to gain access to a lot of the bios functions when you reach the bios.

    Thank you for your replies. This was really useful for me as I've spent about 2 hours looking at manuals of various mobos from various vendors (which didn't show any kind of smaller-than-standard-Vcore support).

    I hope I'll be able to come back soon and tell you how much it draws in idle and in full load.

    P.S.: non-Intel AHCI (shorter boot times), NCQ without AHCI on and the 17.6W TDP of the chipset make up for the lack of dual channel. I don't think I'll miss that very much.
