    Hi all,

    i have just built a HTPC with the aforementioned mobo and memory, along with a 4850e and 750GB Sata.

    it will not boot with the full 4gb of mem, only with 2gb.

    any ideas why the 2 2gb sticks wont work together?

    Try running the ram at a lower speed than rated (i.e. boot with 2, set the speed down, then install the 4) the onchip memory controllers on the Athlons have trouble driving 4 sticks, especially at higher speeds.

    Upping the ram timings and increasing the DRAM voltage slightly may let you run them at max mhz once you do having it booting with the 4.

    i had the same issue with a69 series asus board ...no matter what would not read 4 sticks/4 gig
    threw them in a 69 gigabyte board and it worked with the same chip

    so in my opinion even thought the controller is on the chip the board has to play ball as well.

    try booting one stick as stated and lowering the bus then toss in the other one...my bet is it still won't work.

    As for not running 4 sticks or 4 gig thats not entirely true
    my friend has aphenom 9850 and a 790fx with 4 sticks of geil ultra with no issues,now thta may be the cpu but my bet again is board/chipset related.

    mmk, ill give that a go.

    seems stupid that it accepts up to 16gb and wont work with 4...

    Ive stumbled onto a bigger problem than memory with this board..

    Works great as a HTPC.. low load etc..

    however.. add a GFX card and try to use it as a gaming computer..

    The northbridge goes into meltdown.. and randomly crashes..

    Apparently there is a 1.1 version with a bigger heatsink....

    damn gigabyte!

    try putting in the other stick by itself and see if that works. possbile that memory could be faulty, or a slot on your mobo could be faulty. test other slots, and return for warranty

    thats an easy enough fix with a cheap northbridge cooler
    still not right that these boards...and i mean all boards seem to suffer alot from heat even with these big heatpipes like my p35.
    as for the ram above has 4 1 gig sticks which may mean 2 gig modules might be an issue

    what bios revisions are we using here?

    This is BS by the board makers,you would think that boards are tested for these rams size B 4 putting to market,as for NB heat prob..WTF are they thinking..

    I just got a similar board GA-MA78GM-S2H and that works fine w/ 2x2gb of Kingston (not sure if your board is an earlier version - or a typo?)

    i had same problem with a dual channel kit, so i swaped one of the 2gig stick with another brand and it worked fine.

    Seems to be something special with dual channel kits not working?

    Just this weekend gone I helped a mate put togeather a computer with the same motherboard. Works fine with 2x2Gb Transcend ram.

    EDIT: I just remembered. Both DIMM's need to be in the same coloured slots next to each other. Ie. Put them both in the yellow slots. They will run in dual channel this way.
    Initially I got it wrong and had had one in yellow and one in red = no boot.

    Hey guys,
    I have one of these board in my media box, however it keeps booting due to the LAN boot, But i have this disabled in the bios.
    Is there a jumper on the board or something I have missed elsewhere?

    I tried the GA-78GM-S2H and the northbridge got very hot at idle.
    The Gigabyte heatsinks seemed to be glued and sometimes come loose and just sit there. The official response is that the retention mechanism is adequate and the cooling solution meets industry standards.

    If you are replacing heatsink warm up the chip for ten minutes or so to make removal of their glue type rock hard thermal paste easier.
    Gigabyte responder also pointed out that you void warranty by doing so.

    I am going to try GA-G31M-S2L. For HTPC just add a $40 passively cooled video card instead of stuffing around with additional chipset coolers.

    I own the 1.1 version / 9550 / 4g Kingston HyperX 4-4-4-12, no such problems :tongue:

    The N/B H/S comes stock with thermal CRAP that dries out even before use, once the N/B H/S is bumped it breaks the contact and sits loose, use a decent TP and NP.
