    Default A770DE+ (PciE Green slot problem) Not Working

    Problem:
    I plug my ATI PCIE card into the Green slot and when the computer goes to boot. I get a number of beeping sounds(Atleast 6 or more)! After that, the computer boots and I can hear windows 7 login sound and app sounds like skype load up.

    Problem " While at boot up and loading I have no screens. Both monitors are black!"

    I am able to have both screens and ASrock boot screen if I plug the graphic card into the Orange slot. System will beep twice then boot and load windows just fine.

    Specs
    Windows 7 64bit 8gig memory
    ATI Radeon XT 2900 HD
    Card link: ATI Radeon HD 2900 XT 512MB review
    Board link: ASRock > Products > A770DE+
    Chip: AM2 6000

    Bios is currently up to date 1.70
    I just bought the board off newegg about week ago.. I been using it through an through with graphic card plugged into Orange slot and have had no problems and system seems to run fine.. But I can't understand why the green slot isn't working. Also the manual says if running 1 card plug into green slot. (Note only 1 card is use)

    any help would be very helpful!

    Hi,

    I will try to help you out with your problem.
    I just checked the specs of your motherboard and video card.

    The Orange slot on your motherboard is only a 4x PCI-E slot
    While the Green slot on is a 16x PCI-Slot

    In case you didnt already know the 16x is capable of much higher bandwith.
    So you are definitely not using your 2900XT at its full potential.

    Here are some solutions that I can think of atm.
    1. In the orange slot your video card might be using less power. While in the green slot its needs more power. Check your power supply. Please let me know all the details of your PSU.
    2. On the side of the video card, there should be 2 power inputs make sure you have power cables connected into both inputs.
    3. The green slot might be defective. RMA your motherboard.

    the power supply is called
    rosewill xtreme rx850-s-b

    link here: Rosewill Xtreme Series RX850-S-B 850W

    look at the other things you said.. still yet to get any results to display on that pic slot
    working with power cables to see if maybe I'm missing something

    Hi Simms,

    Ok I just checked that power supply. Thats a good psu, so I am now pretty sure that the power supply isnt the problem.

    By any chance do you have another PCI-Ex video card or any that you can borrow? So that we can test the slot even more.

    If you dont have any other video card to test with.

    I would than highly recommend you to send your motherboard back to newegg for replacement, before your return period is over.

    Yeah don't have another pcie card..thinkin of running out and getting one just to double make sure before I place the mobo in the box and ship it back.. Some reason I just got a weird feeling it's not the mobo..Although I can be very wrong on that judgement

    did note some in the manual what little help it gives saying

    1.if you plan to install only one PCI Express VGA card on this montherboard, please install it on PCE2slot(green)
    2.For the information on the compatible CrossfireX mode PCI Express VGA cards and CrossFireX setup procedures please refer to CrossfireX operation guide on 15page

    does that mean if your card isn't a crossfire card install it on Green slot but if it is crossfire compatible then install in orange if single?

    just guessin at this point though!

    Instruction #1: It means that if you have a single video card, to use the green slot (which is the quickest, out of the other slots). So that the video card can run at its full potential.

    #2: Tells you how and where to set each card of the two video cards, so that they can run in crossfire mode.

    To answer your question, you can use either a crossfire or non crossfire card in the green or orange slot. It doesnt matter ;)

    Trying to find something about my ATI RADEON 2900XT 512 card..

    could it be that it's not PCI-E 2.0 interfaced

    I'm looking at other cards like this
    Visiontek Radeon HD 4670 Video Card - 1GB DDR3, PCI Express 2.0, CrossFireX Ready, Dual DVI at TigerDirect.com

    that say 2.0 interface and my MOBO says PCI-E 2.0
    but on ATI site.. my card just says PCI-E interface

    less I'm missing something

    Just to update anyone else that might ever have this problem.

    Went out and bought a new VisionTek Radeon HD 5550 graphic card. Installed it into the PCI-E (Green slot) and it worked first try.

    Either something is bad on my other card or the mobo only supports PCIE 2.0 or higher.


    either way problem now fixed!
