Xfx r7870 problem

[TimG]

Hello,

I have a XFX R7870 purchased.
My system will not recognize the card as a HD7800 series, but sees it only as a "MicroSoft Basic Display Adapter".

I have the card returned as a DOA and have a new card recovered but this gives the same result. Again "MicroSoft Basic Display Adapter".

If I install the drivers Windows 8 shows a bluescreen and reboot.

Are there more that these problems? And what can I do to solve this problem.

Maybe a BIOS problem?

I have the same problem on different PCs
My pc
MB : MSI Z77A-G43
CPU : Intel i5-3570K
PSU : 750W
Windows 8 Pro

Also tried on a MB: Asus M4A89GTD Pro/USB3 CPU: ADM Phenom II X4 955 PSU: 600W
With win7 and with Win 8

Thanks in advance

Tim

Hi

Welcome to TPU

Edit Default core looks wrong should be 1050Mhz [can you let TPU community know vga card *exact model]

Note: would be odd for for a second card to be doa, note serial number of vga card "is it the same?" definitely new card!

In Test PC Asus M4A89GTD Pro/USB3; all drivers were removed before installing XFX R7870, motherboard bios & chipset drivers were up to date?


-Check HDMI and or DVI cable for bent pins

-Check vga card 6 and or 8 pin power connectors are secure *if required

-Remove the CPU [check pinouts] clear cmos [while cpu is removed]; reseat the CPU; boot with minimal hardware, one stick of RAM [seated in DIMM_1], reseat VGA card [able to boot to bios][able to boot to DOS prompt]

-hdd attached [able to boot to windows safe mode]

-Look here

-check motherboard bios is up to date Note:*"download and execute the file in USB pen drive only."*

Hi,

Thanks for your reply.
Here some answers.

Edit Default core looks wrong should be 1050Mhz [can you let TPU community know vga card *exact model]

Model No.: FX-787A-CD
Part No.: FX-787A-CDFC
DD RADEON 7870 1000M 2Gb D5 2x mDP HDMI 2x DVI

Note: would be odd for for a second card to be doa, note serial number of vga card "is it the same?" definitely new card!

I hope its a new card. The seals on the new box looks like there were new.
I did not checked the serial number. I dont know the serial number from the other R7870.

Edit: i checked the packlist from both cards and they have different barcodes. So i think its a new card

In Test PC Asus M4A89GTD Pro/USB3; all drivers were removed before installing XFX R7870, motherboard bios & chipset drivers were up to date?

All of the AMD software is uninstalled and i used DriverSweeper after that.
The MB bios & chipset are the latest version 3030

-Check vga card 6 and or 8 pin power connectors are secure *if required

The R7870 have a 6-pins and a 8-pins connector , both are connected with a 6 and a 8-pins cable.



Thanks in advance

Usually when it shows "MicroSoft Basic Display Adapter" it means the actual driver is not installed yet.
You might want to try a manual install via device manager.

I give up.
I've done everything on your list but no result.

I did a clean install of Windows 7 with SP1 and. Net4.0
The system recognizes something of an AMD video card but will not boot afterwards.
Only when I R7870 DD (Double Disappointment Edition) remove from the system, run Windows 7 again.

I send the card back this week to the reseller and start looking for a replacement.

I had a HD6870 in my old system but that is overheated. And no longer works.

I need a video card that can handle 4 screens. For a normal price.

3x 22 "(5860x1080) in Eyefinity in my race rig
1x 24 "(1920x1080) on my desk

Anyone have an idea?

shame to hear; however card is dead

For a normal price.

What is your budget?

Where are you purchasing from? US, UK, EU or Other

I need a video card that can handle 4 screens.

AMD Serise

if budget can stretch to HD 7950 with good cooler
or
HD 6970 with active display port support [may be possible to get one of these used for less $]

When i installed this one its working like a charm.

All 4 screens are working great now.
