Installing 4850 in Biostar 790GX

[blackrain]

I have a Biostar 790GX which has onboard or integrated video.

If I want to install a 4850 PCIE, do I need to do anything in the BIOS? If so, what? The manual does not say anything

I happen to have this board and that card.You're right,the manual leaves out a few items,and some bios settings are still a mystery to me.
All i can say basically,is look to where you set these>GFX0-GPP-IGFX-PCI.That is the correct order.I pulled this off another forum to explain it best.GFX0 is external PCI-E graphics, PCI - PCI graphics, IGFX - integrated, and GPP - PCI-E x4 graphics
I would disable integrated video as well or UDMA+sideport setting for integrated option.

I went into the BIOS, changed the order as suggested, disabled integrated video, installed the video card, and don't get anything on the monitor. The fan is spinning. Did I do everything in the right order? Can someone walk me through this? Or do I need to RMA this video card?

Are you saying everything was working fine before doing this?Card in master slot,paddle card in other slot,dvi connector motherboard side,4 pin power to power supply off motherboard 4 pin?

 

[blackrain]

No, its not working at all. What is a paddle card? Are you saying I plug the DVI into the motherboard instead of the video card???


And what does "4 pin power to power supply off motherboard 4 pin? " mean?

You made sure the 6-pin PEG is connected to the video card?

You want the DVI cable attached to the card and not the motherboard.

The motherboard should have come with a card that plugs into the other slot,but even so that is just for assurance to get 16x video rather than 8x.I have found for me,that i had to use the dvi connector off of the video card that is nearest motherboard platform side.There is a 4pin power connection directly on the motherboard you want connected to your power supply.This helps for stability of the video card,and could even cause a no boot without.

Is this a fresh off the drawing board install,like no os yet or nothing?

The 6-pin PEG is connected. I didn't see the paddle card, but will take a look. The 4-pin power is connected to the motherboard (however, it wasn't clear to me whether this was for the benefit of the onboard video only because the 6-pin PEG should be ample power for the video card) OS is installed.

Do these paddle cards only come with AMD mobos?

I have never heard of thuis term paddle card?

Is this some type of card that plugs into the second PCI-E slot?

I also have a Biostar 790GX motherboard (TA790GX-128M) and here was my experience (using a 4870):

- Not necessary to disable onboard video. I eventually did just to make sure it wasn't using any extra system resources and to possibly slightly reduce power consumption, but my initial boot was fine without doing anything to the BIOS.
- There are two PCIe slots. Most motherboards have the primary slot up next to the ports. On this one, the PCIe slot next to the ports is the secondary slot, and the one farther down is the primary. I've only ever used the primary slot.
- I did install the paddle card (a small blue thing about the same length as a credit card but half the width) in the other PCIe slot eventually, but I didn't do it right away. It's not strictly necessary to install it, it just increases the PCIe speed from x8 to x16, which rarely has any effect on performance.

If you're getting no video despite having your card plugged into the proper slot, then maybe your video card is bad. You may have to make do with the onboard video for now. If you disabled it in the BIOS, you'll have to reset your BIOS and then you ought to be able to get it back.

I use an HD4850 in the TA790GX-128M as well. I have onboard disabled and am using the top PCI-E socket. I'm not using a paddle card at all and I have no problems with that setup. I do remember that before I flashed the BIOS I would get a blank screen on cold boot now that I think about it. I had to restart the computer each time I cold booted to get it to recognize the card.

What BIOS are you running?

The original BIOS

So are you saying that I don't need to do anything other than plug the card in, plug the 6 pin into the video card, and boot up?

If its that simple, I guess its time to RMA

I borrowed my friend's 4350 PCIE video card. I installed it with the paddle card in the slave slot. The monitor received a video signal without any problem. I didn't make a single change to the BIOS. I did not disable the onboard BIOS.

I shut off the PC. I uninstalled the 4350 and then installed the 4850. The fan spins. A little red light on the back of the card comes on. But no video signal. Is it safe to say that this 4850 is dead?

The 4350 is a very different card. It doesn't require the extra 6-pin power plug. But I assume that shouldn't matter.
