memory - Can my Motherboard handle this Graphics card?

    I found this mother board online (Gigabyte GA-Z87X-SLI) and this graphics card (Gigabyte GeForce GTX 770 4GB PhysX CUDA).

    The graphics card has 4GB GDDR5 SDRAM.

    So this is the actual problem: The motherboard supports only 1GB of allocated ram on graphics. Does this mean that the graphic card is 3GB too big or does it mean something else??

    In the case that the motherboard dosn't support the graphics card: Can you recomment another SLI motherbard with at least same specs or better? (MUST be gigabyte motherboard)

    Your card will work fine. The amount of allocated RAM is how much on-motherboard RAM you can "shift" to use by the Onboard Graphics processor. The onboard graphics does not have its own RAM, and must use the RAM inserted in the motherboard.

    Since you will be using a dedicated graphics card, with its own RAM, this allocation of RAM does not apply to you.

    Note: I am only addressing your question regarding memory allocation limitation. Other compatibility/stability/driver issues are a risk with any DIY video card installation

    I'm pretty sure that spec relates to the amount of memory that can be allocated for Intel HD Graphics.

    linux - How can I make my PCI-E graphics card visible to Ubuntu when the motherboard has integrated graphics?

    I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first:

    • Integrated graphics
    • PCI graphics
    • PCI-Express graphics (PEG)

    I set the BIOS on PEG, but

    • I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.)

    • I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one.

    • Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says

      Current usage: Unknown

    There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset!

    Other information:

    • The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card.

    • Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power.

    • It gets all its power from the PCI-E slot; there is no external power connector.

    • The BIOS is an AMI Award BIOS.

    My question: how can I make the PCI Express graphics card visible to Ubuntu?

    OK, I am a prime idiot. Leaving this up in case it helps somebody else:

    • To solve this problem, remove the graphics card from its slot and reinsert it.
