1950XTX CF Screen flicker

post #1 of 6
Thread Starter 
I recently got my X1950XTX Crossfire Edition card (Sapphire) and got it installed and set up next to my old X1950XTX with no problems. Now, recently I have noticed that my screen flickers back-n-forth just the slightest bit, maybe just a few pixels to the left and right. It is quite annoying. I was wondering if perhaps this is a noted problem/bug, or if maybe it is a problem with my particular setup. Everything listed below in my specs is what I'm running. My monitor is fairly new, I've only had it maybe 3 months, and I'm pretty sure thats not the problem.
I know I have ample power for the cards as I also upgraded to a Thermaltake Toughpower 750w. I have tried using the options in Catalyst Control Center such as "Alternate DVI operational mode" and "Reduce Frequency yadah-yadah"; both to no avail. I have also noticed the problem both when Crossfire is enabled and also when disabled.

Also, I know that only one of the DVI slots on a Crossfire Ready card can be used for the Crossfire Cable connection. If I have the cable connected to the wrong slot, Crossfire "should" fail to function... correct?

Any help or info on the matter is greatly appreciated!

Well It sounds like a Connection problem to me rather than a driver or Software issue. Have you blown and or made sure that the Monitor connection to the VGA or DVI slot is properly connected and secured.

Also make sure that Both cards are properly secured in the PCI-E slot.

However when performing Driver installs make sure that you use Driver cleaner.

sorry it took me so long to reply... i've been away a few days.

anyhoo, I now know its not the monitor, I tried it on the regular dvi connection point on the new card and, no flicker. Then, i connected a monitor with a standard vga connection + adapter to the crossfire/dvi adapter and, no flicker. I noticed that the dvi connector on the cable from my monitor is missing plugs. I mean, it looks as though it was made that way... Think that could cause problems? I have also heard that the crossfire cables can be hit-or-miss and can have or lead to problems sometimes.

I only have the flicker when using the crossfire cable to monitor connection. It does not matter whether crossfire is enabled or not, the flicker remains. I have also tried enabling spread spectrum, as I thought perhaps a fluctuation of power could be causing it... but to no avail. I have also noticed that I see either no flicker, or very very little flicker at lower resolutions (I'm running max 1280 x 1024). If this continues, I think I'll RMA the card and see if it was just a bad card... could be.

Sounds like a crapped out cable to me. Retry the dongle MAKING SURE every connection is PERFECT. Then you'll likely have to replace the dongle.

Well, what I have done to fix the problem for now, is to use a vga cable w/ dvi adapter-to-dongle from the vga input of my monitor, and the problem is gone. I noticed in the manual for my motherboard, it mentions my problem and gives some suggestions. First, to move away any other monitors or anything that may be creating a magnetic field that can interfere with display. Second, is to make sure that the v-sync is enabled... problem is you cant adjust v-sync when using the DVI connection on my monitor. After a slight tweaking of the v-sync with the vga connection, the screen looks and functions perfectly. I've even noticed a slight increase in display activation time at POST and when changing res.

I'm contacting ATI to get a new dongle though as suggested. I know that the monitor will function more properly when using the DVI connection. A vga connection just makes more work for the graphics cards.
