    Default EP43-UD3L PCI-E Problem

    Hi all!

    I recently had to replace my motherboard/CPU which had died.

    I purchased a EP43-UD3L mobo but am having some problems getting my nvidia 9800gtx to work. Basically when I plug in the card, attach the power to the card and boot her up, nothing happens for about 30 seconds, then I get a single beep and nothing on the monitor.

    However when I swap out the card to an old nvidia 7900gt card (still pci-e), it all works fine!!

    I'm sure there isnt a problem with the card since it was working when I removed it from the old mobo but am at a loss as to what else it could be?? I assumed it was a power problem, but there are green lights showing on the card, and no obvious indicators (that I can tell anyways).

    Anyone had a 9800gtx work with this mobo? The old mobo was a gigabyte GA-M55SLI-S4

    Is the PCIE freq set to 100 in the BIOS?

    Not 100% sure, I will have to check.

    Is there a freq difference between the 7900gt and the 9800gtx? I don't remember having to modify any bios settings when I installed the 9800gtx

    No, but it's possible that 7900gt accepts higher PCIE settings. As far I know, your board has the same problem as mine: it raises PCIE freq with FSB when set to AUTO.

    It's a long shot, but it won't take much time to check the BIOS settings...

    Any other suggestions?

    Have you tried clearing the CMOS?

    I haven't however the mobo is brand new - didn't expect I would need to .

    One thing I did notice is that my old mobo had another power supply going direct to the pci-e x16 cards - however it was a SLI motherboard so it might not be entirely relevant. I'm pretty sure the power is ok to the card since when I plug 2 power leads to it the light is green, and with only 1 connected it is red.

    Yes, you're right - it wouldn't make much sense to clear the CMOS in a brand new mobo.

    Well, I ran out of ideas... It can be your PSU.

    My advice is to post a very polite short post in "Welcome to Gigabyte forum" thread with a link to this thread. One of the moderators will help you. That's what I did when I had a problem with my mobo and I got a very helpful responce from Lsdmeasap. I'm a noob, let's face it...

    Good luck, dude.

    In the integrated Peripherals section of the BIOS there is a setting "Init First Display" set this to PEG (Using your other card) for slot one and see if it fixes things

    What PSU are you using anyway? And yes, you would need to connect some PCIE power cables from your PSU to the card if the card has the power molex's on it.

    Have you or can you test this card on another system? That is what I would do first to be sure the card is not DOA
