No Crossfire option
Hi,
I have a Dell XPS710 which comes with the X1950 Crossfire Edition and the X1950 Crossfire Series. I've loaded the latest drivers and Catalyst (8.33, 7.1) yet I don't have a Crossfire option within Catalyst. I've tried connecting the cable from the VHDCI port on the Edition to a DVI port on the Series card, and the other end to my monitor, but it doesn't display anything. Within Displays Manager I have 4 screens - is this normal? Shouldn't 2 of these be 'merged' if I'm using Crossfire? I'm running XP Home. Can anyone suggest what might be wrong here? Thanks, Campbell |

Thanks, Campbell First, yes it is normal to see 4 screens listed in the Display Manager. Now when you connected Cable from the Master card to the slave which DVI connector did you use? The proper connection would be to the DVI connector closest to the motherboard on the slave card. As I understand it you won't have the option to enable crossfire if the cable isn't connected correctly. |

Yes, I've connected the cable to the DVI port nearest the motherboard. According the Display Manager, this is the Secondary output on the Series card. Incidentally, should I be able to get any output from the VHDCI port if I haven't plugged the other end into the slave DVI port? I've double-checked the connection of the cable, completely removing and re-inserting it and making sure the screws are in tightly. Should I not even have the CrossFire option in the menu tree within Catalyst, even if it thinks it is unavailable? Thanks, Campbell |

... Incidentally, should I be able to get any output from the VHDCI port if I haven't plugged the other end into the slave DVI port? Yes. The VHDCI port is physically just two DVI ports crammed into the space of one. One DVI port is used for input from the slave card, the other used for output to the monitor. The cable itself is just a "dumb" adapter; it doesn't do any signal processing, multiplexing, etc. Should I not even have the CrossFire option in the menu tree within Catalyst, even if it thinks it is unavailable? To complicate matters, Catalyst 6.11 and later drivers introduced "cable-free" Crossfire across any combination of X1900/1950 XT/XTX cards. As such, *if everything is working correctly*, you should see a functional Crossfire option regardless of whether the cable is plugged in, the only difference being that cable-free mode is slightly slower. If you are not seeing the Crossfire option in Catalyst Control Center (CCC), something is wrong. Obviously, make sure you are running CCC in "advanced" mode. Remove the monitor entry from Device Manager, shut down (not reboot), plug the monitor into the dongle cable, and restart. This should allow your monitor to be re-detected. -- "War is the continuation of politics by other means.

You of course have the Crossfire Edition plugged into the Master PCIe slot,
right. You also of course have the power connectors plugged into each card? I just added a X1950 CF card to my system and soon as I can rob a bank I'll get a x1950xtx to go with it. My His 1950 has same timings as the XTX. One more things, instructions say to make sure to check your BIOS to see if there is an option to enable the second PCIe slot. Still another thought, you did uninstall CCC and then reinstall it after adding the second card? If you did not uninstall all the ATI software and drivers, you need to do that now and start over.

I've just opened my machine (it came fully assembled with both cards
from Dell) and verified that the Crossfire Edition card is in the Primary PCIe slot. I installed the latest CCC when everything is in place. In fact I have uninstalled and reinstalled to check that, but no joy. :-( I'm guessing the second card is fine as I can get output from both DVI ports independently. I just don't seem to get any output from the VHDCI port. JamesH wrote: You of course have the Crossfire Edition plugged into the Master PCIe slot, right.

What is the rated wattage of your power supply? Should be over 500 watt,
even over 600. Computer makers normally have PS that barely cover their system. Crossfire is picky on this matter. I had two 1600 series in my system, and did not have to do anything special to get Crossfire working other than uninstall all ATI software when I added the second one. Which is not your case. You do know there is a Dell Newsgroup and you can also get support directly from Dell. Perhaps your system sustained some damage in transit. I'd give dell a call if I were you. They are pretty good people to work with. I too have had a dell in the past. "Campbell" wrote in message ...

... Hmm, so if I'm not getting any output from the VHDCI port, I wonder if there's either a problem with that port, or a problem with the AVI cable. Most likely. There's one more thing you can try. If your monitor accepts VGA inputs, connect it to the dongle cable using a DVI-VGA adapter. Yep, running advanced mode, have tried uninstalling, reinstalling, shutting down, moving cables around in different ports. I get output from all 3 DVI ports, just not the VHDCI one. :-( If my suggestion above doesn't work, then call up Dell's tech support line, tell them all the steps you took (hopefully to save some time) and ask for a replacement dongle cable. -- "War is the continuation of politics by other means.

Ok, I have tried what you suggested. I CAN actually drive the monitor
fine by using a DVI to VGA adapter. But if I try connecting directly with DVI, the display refuses to enable. Why would that be? The signal would be downgraded, so if anything I'd have thought it would be even less likely to work. The monitors are certainly capable, I am using a Dell 3007WFP and Dell 2007FP.
