MSI nForce 680i Refernce board SLI problems

Have the same reference board only mine is MSI (What I've read there is Evga, MSI (Which was not meant for sale, even says it in my BIOS notes... lol) and BFG which are all the same board), I have got my setup to work perfectly but now am looking to SLI it and am getting different results with basically the same config...
This is my board, but mine been MSI branded:
MSI nForce 680i SLI - PSU is 620W (SLI ready) - P Core D 3.00Ghz - 2 3dInno 9800 GT - Kingston standard RAM.
As soon as I boot with 2nd card either powered or with SLI bridge connection the problems start.1st trys I got a Post code 65 - Special treatment for PS2 mouse... But really the computer had crashed, I then went and set BIOS to defaults (cause I had a bit changed in there) did the same thing.
Loaded windows by using 1 card and download and upated BIOS to a version from Feb this year. When doing this I noticed at boot it stopped on same post code 65 BUT ask if i'd like to continue by pressing F1... This started happening each time at every boot. I then when in BIOS and set it to Halt on no errors was Halt on all but Keyboard.
Plugged 2nd card in again with new BIOs which was also booting fine on single card, weirdly it got past bootup got post diplay FF and then got to part just before Wins loads and the screen went all funny (like a half display) for 5 seconds, then back to normal got Vista logo and computer crashed...
2nd try got me where the display goes funny and then just stayed that way. Since the new BIOS and getting through the boot the keyboard was not working, cause each time I try pressing del to get into BIOS but it just keeps moving along like nothing was going on.
After a few restarts, I loaded BIOS defaults, now I dont get past boot again, this time stops on post code 50 which something to do with int USB controller and screen has no display.
I don't think the posts mean anything or have to do with problem. Does it matter which way the SLI bridge faces? oh tested both card by themselves and they both work fine. Done Long Memery test and it check out fine.
Also there is NO RAID config enabled.
Tried more things, loaded Vista with 2nd card plugged in but not powered. Once in Vista I connected the power cable and refreshed in Device Manager and it found the card installed drives and did not crash or anything. But did say it needs to restart for change to take place did that and same thing happened, no display frozen in post code 50...
Tried same thing with XP (Have dual boot) XP could not find the card...
I also read earlier comments about putting a FDD in and it will solve problem, will this work. It's better then buying a whole new mobo and doing all the reinstalling for 2 weeks.
Any ideas? Thanks

    A drive: because that ws posted on this site by user looking for problem solving on EVGA's version of my board, he said he had heard/read that this fixed the problem he was having (Was very vage on his problem only that there was no display at boot-up). Google "no display 680i nForce SLI"... thus how I found this site.

    Msconfig: If I could get to windows in SLI mode I would not be putting $ on this question.

    Restoring BIOS defaults: Already done this says so in discription. Or do you mean back to BIOS OG version?

  • corbettz Dec 13, 2008

    Ok I've figured out to recreate getting passed BIOS boot with some help from some furoms. I can now get into Vista safe mode but to do this I have to disable USB support in BIOS and therefore when I get into Vista can not do ANYTHING!!! So I've ordered a USB to 9-pin conector adapter from Ebay.

    So my next query is what do I do once I'm in safe mode with a working keyboard?

Since setup works perfectly, ruling out the mobo itself, have you tried safe mode or a diagnostic mode via msconfig? And why do you think a floppy disk drive would make a difference?

Try first resetting the bios to default, sometimes there is no way to have a video adapter working when you get this kind of problems, I will tell you more.

    You are telling me that when you install your MSI card (Ge Force 8800 chipset based) into the computer, the computer crashes before passing the post test, or returns errors.

    This happens despite the fact that you already reset BIOS to factory settings, and upated BIOS.

    That means that the card is in conflict with some other hardware device (probably a system device) on interrupt or access to RAM and resources.

    The only additional thing that you can do is trying to disable the on-board video adapter from BIOS (and from windows) after installing teh new video adapter.

    That will probably not work, in this case at a repair shop they would replace the video adapter and use this one on a different PC (or resell it). I guess you will be forced to do the same.

    I answer:

    "A drive: because that ws posted on this site by user looking for
    problem solving on EVGA's version of my board, he said he had
    heard/read that this fixed the problem he was having": I think the A drive/floppy upgrade that this user was referring to was the BIOS update, that often was distributed on floppy, modern computers do not even use floppies anymore.

    "Msconfig" : if you got the errors during post, before starting Windows boot up, this has nothing to do with windows configuration. Dont waste time and dont mess up system playing with Windows config, this is not an OS problem.

    "Restoring BIOS defaults: Already done" : if bios is already updated to most recent verion, nothing to do with that.

    If I was in your shoes I would either replace the video adapter, or the motherboard, you have already done the possible, and the problem looks like it is an hardware conflict.

    "I can now get into Vista safe mode but to do this I have to disable USB support in BIOS"

    |That means that the USB on mainboard is clashing with your video card.

    Instead of trying to find complicate solutions, decide if you want to replace Video adapter or motehrboard, buying USB to 9-pin conector adapter is not a good solution. I any case you buy a pci usb card, not an external connector, if you want full USB functionality : SYBA High Speed USB 2.0 4x Ports Hub via PCI .

Have an EVGA nForce 680i. Bought 2x 2 GB 6400 800Mhz of ram to replace 2x 1 GB sticks. However when I start up the system it only reads that I have 2874 MB of RAM. So I figured maybe one of the sticks is...


The reason its only seeing just under 3GB of memory is no doubt because you are using a 32BIT operating system (probably XP).
If you were to install Win 7 (X32) or a 64BIT operating system the computer would see all 4GB of RAM you have installed.

Its nothing to worry about though as the computer will work just fine. If you were to check in the BIOS you would see all 4GB of memory is there and see by the BIOS.

Please help me to solve no display evga 680i sli (- -)error code

hi im josh in cebu phils.may i help you? friend try my solution ; Problem: Your Monitor Works, but Displays an Error Message Before Windows Loads If you see an error message, you at least know that video signals are getting to your monitor. Look for these common messages:
Bad or missing FILENAME In this message, the FILENAME refers to your video card's device driver file. Make sure that the driver has been copied to your hard disk and selected properly within Windows.
NUMBERxx This type of message (such as 24xx) indicates that you have a defective video card or a problem on the motherboard, or that you are trying to display in a mode that your system can't display. Check all the switch settings on your card and motherboard, and if the problem persists, see a repair technician. try to use that, good luck hope i helped you.
