I recently purchased a HIS x1950XTX Master card from overclockers, to pair with an ASUS EAX1950xtx card on a P5W DH Deluxe mobo. When connected via the crossfire cable, I get a jitter, like the screen is shaking left and right every few frames, both in single card mode and when crossfire is enabled. This jitter does not exist in 2d mode, or when manually underclocking the cards to 2d speeds in 3d. Removing the crossfire cable, and directly plugging into the cards, (obviously without crossfire) removes the jitter. I've tried the stock HIS and ASUS drivers, as well as the catalyst 6.10 betas, and all have this same problem. Additionally, my power supply is fine (550 W sveasoft unit). Any other suggestions, as this amount of jitter is unusable...

Screen Jitter when using x1950 Crossfire

Try completely removing all ATI drivers and downloading the 6.9's again.
Making sure Master card is in the slot nearest to the CPU socket
Why do you think that PSU is definitely ok - it may well be but most people using crossfire ( on the old style cards at least) are using 600 or 700w models

6.9's don't work with the x1950 (only the vendor modified ones, or the 6.10 betas are an option). The 550 sveasoft PSU is on the certified list direct from ATI, and I popped up a voltage monitor to confirm the +12 v line wasn't fluctuating during periods when I encountered the jitter. Lastly, jitter is occurring even with a single card running, provided it is connected to the crossfire cable. There is no jitter if the monitor (DVI, 1680x1050 res) is connected directly to either card. Lastly, the master is properly installed closest to the CPU.
I wouldn't be either, but I'm working on using crossfire arrangements for scientific computing (similar to the folding at home stuff)... For pure gaming, frankly the single card is maxing out everything I throw at it... As a last piece of info, the 12 volt rails pull from a 40 AMP pool, with at least 18 amps a piece on the 4 12 v rails on that psu.

Funny, every single ATi card ive owned has been rock solid in games.

**** sake man. shut up!
You are talking **** again.
Seriously, myself and others are getting annoyed with you comments.
Mine, and 99% of peoples cards are fine.
Mine is fine once the clocks were sorted out.
Have a few of these

if you don;t like my comments then go hide uder your bed and don;t come onto these forums.
i speak from personal experience and i have a x1900xt and i can honestly say that driver wise and stability wise it is a load of crap compared to any nvidia card i have ever owned.
thats a truly unbiased opinion, and i doubt any other ati owner will drop the fanboyism and admit the truth.
not saying that ati cards are crap. but when put up against nvidia card you then realise that ati cards are crapper.

i agree with concorde some of your comments are very untrue and annoying to a lot of people ive noticed this and i know quite a few others that think the same there nothing wrong with ATi drivers never has been your comments always come without back up etc.

you will also note that i did mention that it was in my opinion. and im entitled to my opinion if course. i have had card now from both nvidia and ati.
im not comparing the performance of the card but the driver side of things and the stability.
let me explain.
nvidia have a far superior clock switching system that detects 3d apps and increases card speeds to 3d speeds. this also works in windowed apps such as rthdribl. with the standard catalyst control center on an ati card the 3d speed detection does not work in rthdribl unless its launched into a fullscreen. now the way to bypass this was to use ati tray tools and have it monitor the apps and set clock accordingly.
there is a lot more little niggles about the ati drivers/cards that cause them in my eyes to fall short of nvidia's offerings.
performance is one thing, but straight out of the box setup and use the nvidia cards are far more friendly.
nvidia hardware on the otherhand is dodgey looking at the 7900series failure rate. now even i have had a 7900gs fail on me but still it did not leave a very sour taste in my mouth.
if the ati card i have now had failed on me i would have been very angry since the only thing the card has got going for itself right now is its performance and so far reliability.
i can see i have rattled a lot of cages so far in the ati fanboy crowd a few posts above. i can understand that since if i had never had a ati card and made the above comments then yea you all have the right to get cheesed of at me. but since i come from first hand experience of the x1900xt and i preach it like it is you all get super defensive.
grow up and accept the opinion of others

wtf?
Never had a single problem with my x1900xtx, nor my x1300pro.
They are 100% stable for everything they do.
Ive made about 40 odd pc's with crossfire or a single card and they all run everything flawlessly.
Im anything but a fanboy, i have made many pc's with nvidia's and own a few with nvidia parts too (go7900gtx, 7600gt, 6100, nf4), i buy the fastest for the given amount of cash.
I find your post rather bias, although, i would say ccc is bloated to hell but so is the new nvidia contol panel however, after you first install the drivers you shouldnt need to configure them again, so thats that problem out the window.
The only irritation i had with the x1k series was the bios image corruption on my dfi expert, that was cured a week after i got the x1900.
Mind listing the problems you have had with your x1900, i would like to know what has caused you problems.
To the op:
can i get a few things straight?
you have tried both cards separatly and they both work nomally?
have you tried reinstalling with crossfire already setup?
cables (vga/power) are good?
all connectors are clean and connected well?
power is plentiful?
Yes, seperately both cards work, and with both installed, I can swap the monitor to the second DVI one at a time, and it works. Power is plentiful (dedicated 18 AMP 12 volt rails for each, out of a 40 amp 12 pool, on an ATI certified sveasoft PSU, and voltage monitoring shows no fluctuation on the 12 v rails even when jitter is experienced. The jitter is experienced only when plugged into the crossfire dongle, but is experienced both in single and crossfire mode when plugged into the dongle. Only thing I haven't tried is removing the second card and testing for jitter when connected to the crossfire dongle (obviously on the HSI master card only) =). Cables are brand new, and obviously work fine when connected to the second dvi ports, and all screws are fully tightened (no play exists at any cable connection). Tried with the HSI cd driver, the ASUS cd driver, and the beta 10 catalyst drivers (only available x1950xtx drivers I can find). My theory originally was that perhaps the two cards were generating signal out of sync, causing this jitter, but the fact that it occurs when using only one card as well throws that out...
only problems i had were with the CCC 6.9 officials. but ditching them for the tray tools solved nearly everything.
the 3d detection was the major issue where it would not work in windowed apps. then there were various bugs in the drivers then catalyst ai was set to high and graphics corruption was apparent in a few games.
then there is the crappy x64 driver support. in x64 my performance is lower than that of xp32. over 500point difference in 3dm05 with everydriver setting the same in both opterating systems.
hmm come to think of it that could be the major issue i may be having seeing as im one of the rare people running an x1900 card on xp 64bit. hmmm i wonder....

yea the biggest pain was installing the drivers then setting them up. with nvidia its basic case of get the latest drivers from the official site and your off.
but with ati for me it was get the drivers, fiddle with ccc then find out that its crap and does not allow custom refresh rates at different resolutions etc. then strip out ccc and install tray tools then set the 3d profiles manually so that 3d detection is not only limited to full screen apps etc.
nvidia just seemed to be a more plesant experience from the intitial installation onwards.
but your true in saying that once your done with all the hokey pokey then your set to go. but id hate to have to see a noob at it for a first time ati install..
