New 6770 not being recognized?

[ogre44444]

I just got a Radeon 6770, installed it, installed Catalyst Control Center from the disk it came with...but I can't find the card in device manager (just my integrated 4250). I haven't uninstalled the onboard graphics card yet, but the new one should be visible i the device manager, shouldn't it? I'm afraid to uninstall the old one until I know the new one works.

I plugged it into the PCI-Express and connected it to the power supply.

Could I have missed a step? My mobo is a GIGABYTE GA-880GMA-USB3.

did you go to bios to select your gpu???

is your fan spinning???

did you UNinstall your old drivers before installing the new.....
by the way dont use the ones on the cd go right to amd.com for the new ones

 

[ogre44444]

Sorry I should have mentioned -

Yes, the fan on the gpu is spinning, so I think it's plugged in right. And in my Bios, under I believe "initialize display settings" or somesuch it says PCI Express, which I assume means my gpu is selected.

Would the old drivers prevent my computer from seeing the new piece of hardware?

Thanks so much, I appreciate it!

Yes on the driver part,

Also, what version of the PCI-E X16 slot is your GPU and motherboard?

Should be something like 1.0, 2.0, 2.1

 

[ogre44444]

It's a 2.0.

And okay, as soon as I get home from work today I'll remove the old drivers and see what happens.

When you installed the new card - did you connect the cable to the new card's display port? If the monitor came on - then chances are your card is working and that it is recognised.

If it didn't/doesn't - the problem lies in de-activating your onboard graphics card altogether - this can be done in BIOS or/and by adjusting jumper settings. This should be covered in your mobo manual.

If you have your BIOS settings set correctly, and you have used the jumpers (if applicable) to de-activate your onboard graphics - your new card should work - then you can install Catalyst. If it doesn't work, doesn't get detected (i.e doesn't display a thing), then there could very well be a problem with the graphics card itself.

Drivers do matter, but a graphics card should be able to display regardless.

When I plug the HDMI cable into the card it doesn't do anything, just have a black screen.

My mobo's manual for installing a new card describes how to insert the card, and then says "Make any necessary BIOS changes"....it doesn't say what to change, haha.

It does give instructions for CrossFiring though. Could that solve my problem? The onboard is a 4250.

Set Internal Graphics Mode to UMA
Set UMA Frame Buffer Size to 256 or 512
Set surround view to disabled
Set init display first to onchip vga

I set init display first to PCI, and I set Internal Graphics mode to disabled, but when I did the latter my computer just wouldn't turn on and I had to CLR CMOS.

I also just tried setting init Display to PEG, but that didn't do anything either. My computer still just sees the 4250.

My documentation also doesn't say anything about jumpers, so maybe I don't have any on my mobo?

Thanks for taking the time to reply to my post, I really appreciate it!

Is the monitor hooked up to the port on the new card or still in the onboard card ? IF the display is plugged into the onboard video port the system will use the onboard video.

PEG is the correct initial display setting for using the PCI-e slot so that is the one you want to chose in the BIOS -- then make sure the new card is seated properly in the slot and that you have the 6 pin PCI-e auxillary power wire plugged into the new card as well - and that the monitor cable is plugged into the new video card and start the system.

If it still does not work correctly you might need to download newer drivers from ATI -- the 6770 is a renaming of the 5770 and when first released was suppose to only be for OEM usage and not retail sales so some of the ATI drivers will not recognize the card (even though they were included on disk with the card) IIRC ATI has since released newer drivers that will work on them so you might need to download drivers directly from ATI. (But the card should still work in VGA mode even without proper drivers - so that you can at least boot into windows and download the new drivers)

 

[ogre44444]

Okay so:

I took the card out and put it back in. Turned the computer on with the HDMI in the videocard - the fan was spinning, but no picture. I put the HDMI back in the mobo, went to bios and ensured I had PEG set for my videocard. Started windows, uninstalled the 4250 from device manager, downloaded the latest version of Catalyst from ATI. Nothing.

If the fan is spinning, then that means it is correctly plugged in, right? And *probably* that it isn't broken? Is there something really obscure with BIOS that I need to do? Because windows seems to know nothing about the card.

 

[JDFan]

DId you also plug in the 6 pin power supply wire to the back of the card ? -- the card will pull some power from the PCI-e slot but needs the 6 pin connection to run.

As far as windows is concerned even if it does not recognize the card it would boot in VGA mode (since all video cards support that and that way it can load the system and then allow you to install drivers) - so that shouldn't be the problem. At this point after what you have tried I'd give the support line of the manufacturer a call to see if they have any suggestions or to arrange an RMA.

 

[ogre44444]

Yeah the card is plugged into the PCI slot, and the power supply is plugged into the back.

hmmm, well I guess I'll fiddle around with it some more and if I figure out what works, I'll post it.

Thanks for all your help and advice 🙁.

This exact same thing has happened to me. Somewhere in these hallowed threads lies a post by me wailing in dispair at my stupid 5670 not working -

I tried everything:

1. Drivers
2. Cables
3. RAM
4. BIOS change
5. BIOS flash
6. Resetting the CMOS
7. Trying a different monitor
8. Buying a new PSU (if a card doesn't get enough power it just wont work)
9. Praying

The solution was simple : My shiny new graphics card was a pricey brick. I tried another (same model, same batch) and it didn't work either. I took them to the computer shop - the GPU's were defective. They put in a 6750 instead - boom, it worked.

The obvious thing to do would be to put it in another machine if possible. Or take it to where you bought it/your local shop and get it tested. If it is bricked - you can send it back for a replacement (but make them aware that you want a different batch, or perhaps ask for a better model.)

If it isn't bricked - then your problem could lie in a few places: -

1. Your PCI-E slot isn't functioning properly. (get new mobo)
2. Your PSU isn't functioning properly, or doesn't give enough power. (get new PSU)
3. Your BIOS isn't saving the settings correctly (update the BIOS or reset it by removing the mobo battery)

Your last resort would be to take the whole thing to a computer shop and pay the thirty odd notes to get the system checked.

Good luck.
