5870 not being read

[miwanuma]

Hello toms I have 2 5870's and when i plug them into pci slots device manager does not see them. The fans are running but thats it. Ant thoughts??

So just to understand . . . you have no graphics adapters showing in Device Manager . . . and yet you must have a screen display in order to notice that. What resolution is your screen currently using?

Did you install the drivers for the 5870?

Did the 5870s replace some other graphics card?

Is this a new build? And please tell us the rest of your configuration.

Hi it is a rebuild with a new hard drive. its running at vga adaptor. have it plugged into hdmi on mobo. Have not installed drivers because i have a new hard drive in it. This is a rebuild from a water build.

If you install a new hard drive you will probably need to install drivers as none will be installed...... you should install drivers if you install a new graphics card anyway.

Don't you also need to tell BIOS to ignore your onboard graphics and use PCIe instead?

I dont remember having to change in bios. Just installed ccc on and windows and now I am getting 1920x1080 on resolution , but still does not see 5870. Might you know where in the bios that might be?

 

[miwanuma]

ok so in bios i see for primary video controller
GFXO-GPP-IGXF-PCI
GPP-GFXO-IGFX-PCI
PCI-GFXO-GPP-IGFX
IGFX-GFXO-GPP-PCI

mEAN ANYTHING TO ANYONE

Back to basics - is your monitor connected to a 5870?

Are the two 5870s connected by the Crossfire cable?

In BIOS, there will be a section called "Onboard peripherals" or something like that (varies by mfg). Since your board has integrated graphics, somewhere it must have an option as to which graphics to use. You want PCIe.

 

[miwanuma]

With monitor connected to a 5870 it does not work. Yes the 5870's are connected by a xfire cable i will check for pcie ..

 

[Twoboxer]

It doesn't work because your mobo is still using the onboard graphics adapter.

 

[miwanuma]

My hwid does not see them either. I will look more in bios

 

[miwanuma]

Closest I see is PCIPnP..... plus and play os set to yes

 

[Twoboxer]

Please give motherboard make/model - I'll try to find the right area of BIOS for you.

Section 3-5-22 in your manual: On the AI Tweaker menu, Select Internal graphics mode and set to "Disable".

Now its getting wierd after i change in bios it wont post. I have to hit the mem ok and it will post, but it wont save that ai tweaker setting

 

[Twoboxer]

Put ONE 5870 in the PCIe slot nearest the cpu. Remove the other. Attach your monitor to the 5870 and try again.

 

[miwanuma]

card closest to cpu with ai tweaker set to disable no post, mem ok button bios gets reset to default boots up monitor only works off the mobo output

 

[Twoboxer]

Are your two power cables plugged into the mobo? Have you plugged a power cable(s) into the 5870?

 

[miwanuma]

8 and 24 pins plugged in. 2 pci power cables on 5870 fans working

 

[Twoboxer]

Clear CMOS and load BIOS defaults. Make only one change to BIOS before saving - disable integrated graphics.

To clear CMOS, turn off psu and pull plug from wall . . . remove the battery from the motherboard . . . press the case power button a few times (to discharge psu) . . . wait 5 minutes . . . put battery back in . . . plug psu in and turn it on. Power up and go straight to BIOS.

 

[miwanuma]

ok did that wont post on disabled, New motherboard btw.

 

[miwanuma]

Just for testing sake I went to frys to buy another mobo. New mobo same effect when I change the internal graphics mode to disabled. Does this mean my cards are fried??

 

[bdcrlsn]

Have you tried a DVI connection to monitor from the graphics card?

 

[miwanuma]

DVI to monitor nothing.. No 5870 shown in device manager
