Hi,

I have a single 5850, which is currently not clocked and this is on an i7 build clocked to 3.9. I am finding that occasionally on boot the display seems to flicker on and off as if the display is dropping connection. After a couple of reboots it boots fine and plays games without any corruption and will stay fine until it needs to be rebooted. I was wondering if anyone else had an issue like this and if there is a solution? It's basically more annoying than anything.

Thanks in advance,

Cheers,

Blue
 
I've had a similar intermittent problem with my Crossfire XFX 5870's (at default speeds) which started Friday night. I would have a display through the load up of Win 7 but then I would occasionally lose connection before the desktop would pop up and would stay blank (like a black screen of death).I was hoping that I might get the atikmdag.sys "blue screen of death" which usally means a driver change to resolve but even that did not rear its head! Reboot would sometimes fix it but I decided to do a restore which solved the problem.

However, on Saturday same issue raised its head again so I did a further restore and it again showed Win 7 loading but the desktop wouldnt display at all even after several reboots?:confused:

So yesterday I put just one of the 5870's in on its own and it would not post :eek:
I put the other 5870 in on its own and the system boots and runs into Win 7 fine. Even tried the same PCIE connectors that were in the dodgy 5870 but it worked fine.

Come to the conclusion that its broke! :mad: I have had to RMA the dodgy 5870 back to the supplier I bought it from. Only had it 3 weeks! :(

Hope your dont have the same result as I have had.

I had this problem with my 5850. I replaced the DVI cable on it and it seems to have done the trick. There was some setting that you could change in the CCC about monitors, forgotten what the name of it was as my CCC won't install.
 
Hi,

I have the latest update for my motherboard and am thinking of trying that. I am also going to lock the PCIX frequency to 100 and see if this helps at all. As I say once it works, it's fine, but it's annoying getting it to work. I have it linked using a HDMI, not sure if that could be the issue?

That might be worth a try. If not try swapping the cable on the slot of the graphics card. HDMI shouldn't be the issue.
