I originally put this question to Motherboards but I think I may have been wrong in my belief that it was a mobo issue.
I recently bought a XFX Radeon HD 5870. I am upgrading from two 9400 GT's.
I did everything correct to my knowledge, uninstall the Nvidia drivers and install the ATI etc. However, when I install the card physically I get no display and my AMIBIOS debug readout displays a code 2A.
The Manual for the BIOS says that code means this:
“Initializes different device through DIM
See DIM Code Checkpoints section of document for more information”
The DIM Code Checkpoints says:
“Initialize different buses and perform the following functions: Reset, Detect, and Disable (function 0); Static Device Initialization (function 1); Boot Output Device Initialization (function 2). Function 0 disables all device nodes, PCI devices, and PnP ISA cards. It also assigns PCI bus numbers. Function 1 initializes all static devices that include manual configured onboard peripherals, memory and I/O decode windows in PCI-PCI bridges, and noncompliant PCI devices. Static resources are also reserved. Function 2 searches for and initializes any PnP, PCI, or AGP video devices.”
The card draws power and heat up but I don't get any display. XFX told me to send it back, but they tested it and it was fine. They are sending me a new one anyway. Any thoughts of what I should do when it gets here?
I have since put the 9400s back in and they work fine.
Here are my specs. Nothing is OCed I don't have the cooling solutions to handle it at the moment.
Often people can "uninstall" drivers but they're still hanging around in your system. Guru3d's driversweeper tool is great in that it FULLY removes the drivers, definitively solving the issue of conflicting drivers.
Got the card today and used driversweeper to get rid of the nvidia drivers. Worked like a charm at first but i rebooted and its stuck trying to POST on the same error, or at least i believe that is what it is doing. THe card clearly works but i can't even get the BIOS to come up. I am getting quite frustrated because I feel like this must be simple but I am not sure what to do.
I may be fixating on the error code too much and that may be blinding me I don't know. Any help is still appreciated though.
I have tried installing and unistalling all the related drivers now again and still no good.
Its working like a charm now, only problem is there is something up with how it interacts with my sound card, which I removed for now and will look at the problem later. Currently I am happy to have a new video card in.
