Single-Card Dual GPU

Both Gigabyte and ASUS have been demonstrating their single-card, dual GPU solutions for quite some time now.  Both cards are at the show itself, first let’s look at ASUS’ card:

The ASUS card is much larger than normal PCI Express graphics cards, and thus will only fit in larger cases.  The board is made of two GeForce 6800 Ultras and will work in any nForce4 SLI motherboard.  Note the lack of any SLI connector on the card, so don’t expect to be able to SLI two of these together. The ASUS card also requires two 6-pin PCI Express power connectors.

Next up is Gigabyte's solution:

Gigabyte’s card is a normal height graphics card unlike the ASUS solution, but still full length.  The Gigabyte card features a pair of GeForce 6800GTs instead of 6800 Ultras, but the benefit is in that it is a much more reasonably sized card and it only requires a single 6-pin PCI Express power connector.  Just as the ASUS solution, Gigabyte’s card requires a nForce4 SLI motherboard and can’t be paired with any other cards.

    BTW where is the $50 ram card?
    Anandtech says:

    Prices $88.00
    Amazon Marketplace $91.54
    Monarch Computer Systems $87.00

    Since when do you need hardware to have a ramdrive?

    Hookup a ups to a ram drive? Why not just hook it up to your computer if you don't want to lose the ramdrive?

    Buy the slowest ram you can for your hardware swap drive?

    Why not have a ramdrive using the fast ram you have installed on your computer and aim your swapdrive at it?

    I think everyone has gone buggy.

    Accroding to this article, the PCI slot powers it up while the computer is off and therefore the battery is only for when it is unplugged or during a power outage.

    how about this:
    1-set your PC to boot off SATA first as in:
    no OS goto harddrive
    OS goto SATA ramdisk
    2-mirror your xp install to your 4G ramdisk
    4-configured for ALL OS functions running off the SATA ramdisk (including swapfile, temps, etc.)
    5-never leave your PC off for more than 16 hrs.

    I'd really like to run the Gigabyte ramdisk for my pagefile.
    The key factor would be finding slow (cheap) RAM.

    My thoughts on more system memory vs. ramdisk:
    Yeah, more system memory is obviously better. But with system memory you're trying to milk every bit of speed you can--and that's expensive. Most folks top out around 2gb or even 1gb. 4Gb is troublesome.
    It seems that a cheap 2-4 gb ramdisk for the pagefile would be an excellent addition to 2Gb of system memory.

    Why don't DIMM manufacturers make something like this? Seems like they could build a big PCB with 4+ gb of appropriate and cheap RAM chips (instead of whole DDR DIMMS designed for a completely different application). One big-ass memory module. Wouldn't this be a more elegant and cost-effective solution?

    Actually, nevermind my last comment.
    This is an absolutely awesome way of doing it.

    Gigabyte; please pat your engineers on the back.

    Any word on eta/avaliability?
    I want one now! Now as in yesterday :D

    2 months ago I posted my ideas about a PCI-E based RAM card on OCAU and a couple of other forums. I even emailed a couple of big-name companies, but not gigabyte. My mistake it seems :/
    (link to my post :

    The concept drawing is crude, but I still hope that someone makes it. Even in 1x mode it'll have nearly 4x the bi-directional bandwith of PCI.

    Gigabyte, if you're reading this, pretty please :)

    Because you can buy cheap ram for the board, and it won't hurt performance. The limiting factor will be the sata connection, not the ram speed.

    Whereas there's problems with 4GB of system memory, such as many OS' not liking that much, many motherboards not supporting that much, and if you want to run at DDR400 you're going to have to buy expensive ram.

    Also some of that system memory would have to go towards the system and not the ram disk... in the end you'll probably max out at a 3GB ram disk or so. And finally with the add-in boards you could raid two of them together to create ram disks > 4GB in size, which would otherwise be impossible since no ram disk software seems to support sizes over 4GB, at least on Windows.

    If you're willing to buy 4gb of ram to put on the ramdrive, why not just put it on the mobo and just have 4gb of ram?

    unless you want it for startup, i don't see why anyone would want it.

    Also, thanks for the URL. I haven't read it yet (SFF is not a priority for me) but I will make sure to read it. thanks again.
