Well, after spending TONS of cash, my computer issues are still not
solved. I am sad.
Computer:
Intel E6700 Core 2 Duo CPU @ 2.66GHz ) w/ copper heat sink + thermal compound)
ASUS P5W DH Deluxe Motherboard
2 x HIS 1950XTX GPUs in Crossfire w/ Dongle
150 GB WD Raptor HDD
Creative Soundblaster X-Fi Extreme Music Soundcard
Enermax Liberty 620 Watt PSU
4 GGB OCZ Memory
LG DVD/R
Creative Inspire 5.1 Speakers
Samsung 2693HM 25.5" LCD (TN panel w/ DVI connection)
Logitech G15 Gaming Keyboard
Logitech G5 Laser Mouse
Windows XP x64 Professional
To be fair, I did have issues with heat, mother board and CPU usage, soundcard, etc... that were resolved. But the underlying issue that caused me to have my system checked out in the first place is still there.
When my crossfire cards go into 3D mode (games, google earth, etc....) the image on the new 26" Samsung LCD I have oscillates back and forth or "jitters".
I have tried this on:
3Dmark06
Neverwinter Nights 1
Neverwinter Nights 2 (totally different game)
Simearth 3D screensaver
On all of them the screen jitters back and forth. Interestingly, on the CPU tests on 3Dmark, the screen does not jitter - but it does on the graphics tests - leading me to believe that going into 3D mode is the issue. There are no issues with video or any other 2D applications.
I have a clean reinstall. There are no viruses. Heat has been managed. All my connections are solid. The PSU is running well and adequate. My 3DMark06 score tests perfectly for all of my compnents which are all at factory timings.
I didn't know what to do until I say this post:

After reading it, I:
1. disabled crossfire in ATI CCC
2. Disbled the secondary card in Device manger
3. Unplugged the Crossfire Dongle
4. Plugged my monitor into the master card directly
Voila! just like this person reported, no problems. But no crossfire. When my computer worked perfectly, I was using a CRT with a DVI (from Dongle) to VGA adaptor. But that monitor isn't working anymore.
The original post I linked to was sevral years ago and concerned the X1900 - not X1950 series cards. And the drivers I have are much newere - but still the same issue. Does anyone have more up-to-date info? Or understand the issue better than I? Enough to offer me more options than essentially unplugging one of my cards. Could I use a DVI to VGA connection with my LCD? That might screw with image quality in other ways, right?
EDIT: This archived Post has some fix suggestions but I can't really follow the tech speak - do they work?
