Video Artifacts: Radeon 9800 Pro + ACD 23 (Clear) + G5

Hi guys.
I've been experiencing some video artifacts with my retail version Radeon 9800 Pro 256MB (not the OEM "XT" version from Apple) which is driving my ACD 23" (Clear Enclosure), which is connected to a Dualie 2.5GHz G5 running Tiger 10.4.2.
Prior to installing the upgraded video card, I never had this problem, so I am pretty sure it's the card.
It has only happened to me when the G5 wakes from sleep. And it doesn't happen very often, either. Maybe 1 out of 20 wakes from sleep. The only way to get it back to normal is to turn off the G5 completely, disconnect the ADC connector cable from the back of the video card, and then reconnect it and reboot.
I also have a second display connected to a Radeon 7000 via VGA and when the artificats appear, the other display is just fine. The weird thing is that I can actually take a screen shot of the artifacts, which I thought wouldn't show up. I am not sure what that means, but I think the fact that I can take a screenshot of it tells me the display is being corrupted at the system level. Right?
Any help would be appreciated. TIA.

Hi Bryanus,
Did you have an ADC port on your old card? Do you still have your old card? If this is the case, you can verify that the new card is implicated by re-installing your old card and seeing whether the problem repeats itself.
If you only have DVI on your old card, you would have to borrow an adaptor, but then you are relying on the adaptor to function properly.
If the problem doesn't repeat itself with your old card being used, then the new card is the culprit, in which case I'd ask to have it replaced, or get a refund.
If the problem does repeat itself with the old card, then you might want to consider other possible contributing factors such as the physical state of the monitor connection (dirty or tarnished contacts, bent pins etc.).
If the problem repeats itself with a new (replacement) card, you could add AGP slot issues to the above paragraph.
"Sleep" in an Apple Mac often generates issues with third party hardware, so your primary consideration that it is probably the card is (to me anyway) still the most likely.
All the best with the diagnosis!
Cheers!

  • Radeon 9800 Pro (128MB) on G4 with lots of artifacts

    Hi there,
    I recently bought a radeon 9800 pro (mac version) over ebay. I put it into a d1ghz (quicksilver with 1.5GB of Ram. Everything seems to work fine, however, the screen flickers ever so slightly after the ripple effect in the dashboard. Yet this is not really what bugs me: Any game (and probably other applications as well) which uses Core Image produces huge artifacts. There are just random screen-filling bits sticking out the ground...
    How do I get rid of this? I already checked all the connections, ran software update, downloaded the most recent drivers and tried downclocking the graphics card.... (I also think that I cleared NV- and PRAM, but I am not sure... )
    What am I forgetting?
    Thanks already, dl33

    Hi. I had the same problem, but it was a 500 mhz Sawtooth. I was told it was either a power issue or a heat issue. So I upgraded the power supply from 237 watts to 400 watts. It seemed to help, but it started doing the same thing. After wasting a lot of time and money with power supplies and soldering and adding fans, etc, I looked at the fan on the card. Like you, I bought mine used. The guy said it worked flawlessly. When I first got it and experienced the problems, I checked the fan. It wasn't the stock fan, was a unit from Arctic Cooling. The fan was spinning, but it said that air should be blown out the exhaust, and I felt none. Upon closer inspection it turned out that the fan was defective. It was constantly speeding up/slowing down, and it was supposed to be a single speed fan...not good. But by the time I figured that out, the card had been fried. I got a new unit from Arctic Cooling, but the card no longer works.
    Might want to check the fan and make sure it's spinning. Your power supply should be sufficient since I believe the QS's had 344 watt PSU's.
    One thing I forgot to mention was that underclocking it usually helped. I had to underclock it a good amount, though. I believe it was around 20%.
    Hope this helps.

  • Can I replace an ATI RADEON 9800 PRO-(256MB)-MAC EDITION with Mac ATI Radeon 9800 Pro 128mb Video Card For G4/G5

    Hi,
    I am trying to help a friend whose graphics card has bust.
    The old one was an ATI RADEON 9800 PRO-(256MB)-MAC EDITION.
    I've been looking on ebay and it seems a lot cheaper to get a Mac ATI Radeon 9800 Pro 128mb Video Card For G4/G5.
    Can I just swap them over?  The connectors are not identical according to the photographs.
    Thanks.

    I'd like to thank everyone for all the really useful information in this thread. It helped me solve a similar problem, which I'll describe here briefly in case it helps someone else.
    I have a 2004/5 dual 2 Ghz PowerPC G5 and an Apple Cinema HD display linked, as I later found out, with the now defunct ADC connector. The display suddenly started to look like that scene in The Matrix, when code falls like rain down the screen, and I worked out I needed to replace my Radeon 9800 pro video card (I discovered the board was blue when I removed a thick layer of dust).
    I took japamac's excellent advice and bought a Geforce 6800 Ultra from the linked eBay seller in Hong Kong, who delivered it extremely quickly, along with the cables to plug it into the DVD drive power source and a CD with installation instructions. It was only then that I realised the card had two DVI connectors and my display needed ADC (I hadn't understood the difference).
    eBay came to the rescue again with a seller who had a secondhand DVI to ADC adapter, which Apple produced  when it phased out ADC about six years ago but no longer sells. It has its own power supply and looks like a large version of the Mac laptop power cables - and has added signifcantly to the pile of spaghetti under my desk.
    Installing the Geforce 6800 Ultra is fiddly, and a bit scary if you're not used to delving into the insides of a Mac, but the instructions were clear and illustrated with useful photos. The video cable has four connectors. Two fit into the end of the card, the other two (linked in a Y shape) form a bridge between the DVD/superdrive and its power cable. You have to remove the DVD drive, unplug it, and then plug one of the two Y video card connectors into the DVD power cable and the other into the DVD drive itself. Then you replace the DVD drive, plug the two remaining cable connectors to the video card and ease it into the old card's AGP slot.
    Finally, with the G5 reassembled, plug the adapter's DVI connection into the back of the card, plug the Cinema Display ADC cable into the adapter block, plug the adapter's USB cable into the G5 (this enables the the USB ports on the back of the display to work), and power up.
    At the time of writing, the display has been up and running for a couple of hours and all seems fine.
    Thanks again everyone for all your help and advice. If it wasn't for communities like this, it would be virtually impossible to solve problems with old but still serviceable Macs.

  • S-Video not working on ATI Radeon 9800 Pro????

    I've had this ATI Radeon 9800 Pro in my MDD dual 1.25 G4 for a little while with two VGA monitors. I recently got rid of the secondary monitor and moved a 27" flat screen tube TV next to the computer. As I always do, I've got to start tinkering. I remembered that my Radeon has both VGA, DVI, and an S-Video outputs. I simply ran an S-Video from the card to the TV. I can't seem to get it to work. I had never used the ATI control panels so I went ahead and downloaded and installed it. It won't "detect" the TV in the Mac2TV control. What the heck am I doing wrong???? I emailed ATI and they just sent me a form reply to a dead link saying that my system is unstable. UGH!
    Any tips would be great.
    Thanks much,
    Robert

    Well, I figured out that if I reboot and only have the s-video attached and no monitors to the VGA or DVI it will work. It dedicates the TV as the primary screen. However, not the best picture. I can't find any information if both the s-video and VGA or DVI can operate at the same time. I'm also doing a little more research with ATI to see if they actually have a true component output from either the VGA or DVI. I had bought a DVI to what I thought was supposed to be component but it was actually RGB component and just gave a distorted image. If I can get that to work, I think it would be a better image along with being able to run both the monitor and the TV as the secondary.

  • Having trouble with my G4 MDD 867MHz DP and ATi Radeon 9800 Pro video card.

    I just recently purchased the ATi Radeon 9800 Pro Mac edition card on ebay. I installed the card on my G4 and turned it on thinking everything would work with no problems, but when I turned it on the grey apple screen came up fine and then it changed to a sky-blue screen with nothing on it and remained on that screen. My desktop or any of my apps did not load up at all. I reset the PRAM and the NVRAM as the seller I bought the card from instructed me to and still I get the same result. Is anyone familiar with this problem? I was wondering if my monitor was the problem because I'm using a Dell LCD monitor as the display for right now? I need help! I'm trying to get this up and running so I can start editing. Whatever information anyone can give me will be greatly appreciated!

    Sometimes display cards that support multiple displays (or a second display card in the same Mac) can cause the display you are using to be the SECOND display in a multiple-display "extended desktop".
    When this happens, the MenuBar and cursor may be drawn perfectly, but be on the "other" screen, and it is very difficult to determine what has happened. \[This problem is sometimes caused by inadvertently leaving an adapter or cable on an unused display port.]
    Try moving the mouse many times to the right to see if the cursor suddenly transitions onto your screen, then try the same experiment to the left.

  • ACD 23 and Radeon 9800 Pro - strange behaviour with color profiles

    Hello,
    I have just purchased a 23" Cinema Display. The first one I got in the store exhibited ghosting effects that ceased to exist after a few hours (self healing effect?) and I also noticed after a while using it, that the left side and especially the lower corner were darker than the rest.
    So I took it back yesterday and got a new one which is close to perfect. Neither of them had any dead pixels! I am very pleased with it and knocking on wood, hope that it stays that way;-)
    My hardware: The display is hooked up to a G4 MDD dual 1,25 with a Radeon 7000 pci card and a Radeon 9800 Pro AGP card. The latter card was put in for the Radeon 9000 pro that came with the computer. So far I have been running a dual display setup with a 21 and a 17 inch CRT.
    Now comes my problem:
    I calibrated the cinema display hooked up to the 9800 Pro with the eye-one and the eye-one match software. The profile I got was not a smooth curve, but a zigzag curve. Of course that is by no means usable for anything.
    By numerous trial and error attempts, I did find out the following:
    - If I calibrate with the eye-one, I can have only one monitor hooked up to the computer, otherwise I will always get zigzag curves in the profile.
    - If I look at numerous testcharts(greyscale, etc.) with the newly created profile, all looks very good and in specs. As soon as I hook up the second monitor again, something changes on the cinema display, even though the profile has not changed. My testcharts look a bit contrastier and on the greyscale the two darkest and lightest fields do not seperate anymore.
    Rebooting does not help either. As soon as I unplug the second monitor, everything looks perfect again.
    I know that this is an unusual issue but I hope that someone here has a clue to where the problem could be. I have tested so much and do not find a solution.
    I will call the apple hepldesk, but I already know what they will say:"The display is working as designed. Your issue has to do with the graphics card and that is a third party product. You have to call ATI for support".
    So, maybe I can get some help here.
    Cheers

  • Radeon 9800 pro 256mb hanging on blue screen

    I'm deep in the waters of frustration right now, and am hoping someone here might have the answer.
    About 3 months ago I was looking for a video card for me to run motion. I saw the 9800 mac special edition with 128mb video ram had rave reviews. At that time ATI was not making them. So I turned to eBay...
    I purchased a card that was advertised as a Mac 9800 pro special editing 128mb. I later found out it was a flashed pc card. The ebay seller told me the card worked fine on all his mac's that he tested it on.
    The problem I was having was the machine boots up, I see the grey screen with the Apple logo and spinning wheel. I see the blue screen where normally I see the login progress bar loading the OS. But with this card I only see the blue screen. I hear the hard drive churning, so I am assuming it is still loading the OS, but I cannot see anything. I can reboot in safe mode and the video card works fine.
    Well... I assumed it was the fault of the card and that it was flashed. I returned the card to the ebay seller, who sent me another one, same results with that one. I returned the card to the seller and he refunded my money.
    I put the money toward the just released Radeon 9800 Pro Mac Edition 256mb card. I just got it a couple days ago and am experiencing the same problems. I have tried everything... everything I know and still can't get the card to work? Here is a list of what I have done:
    With the flashed card:
    1. Shut off computer and unplugged it. Removed OEM video card and installed ATI 9800 card. Plugged the power supply cable for the card into the computer power supply cable and hard drive.
    Problem Occurs: When starting up, the grey screen comes up with the Apple on it, then the screen turns blue, where I typically would see the progress bar of the system loaded up before the user login screen. I only see a blue screen at this point but can hear the hard drive working for about a min.
    2. Restarted the computer in safe mode.
    3. Logged in as Admin user and opened the ATI preference pane to verify it sees the card.
    When the ATI preference pane was loaded the following error message occured:
    A startup problem has occured.
    Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
    Clicked OK and the ATI preference pane appears.
    4. Close the preference pane and reinstalled ATI Displays 4.5.6. Restarted computer.
    Problem Occurs
    5. Restarted computer holding down AppleOption+PR to clear PRAM. Cleared the PRAM 4 times in a row, by allowing the chime to happen 4 times.
    Problem Occurs
    6. Shut computer down. Disconnected the DVI plug for the cinema display and connected a VGA CRT monitor. Started computer.
    Problem Occurs
    7. Shut computer down, disconnected the VGA CRT monitor. Reconnected DVI plug and restarted computer.
    Problem Occurs
    8. Started the computer in safe mode. Logged into admin account. Opened the ATI Preference pane.
    When the ATI preference pane was loaded the following error message occured:
    A startup problem has occured.
    Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
    Closed preference pane.
    Went to ATI site and downloaded:
    aug2005-radeo-universal-rom-update.dmg
    Ran the updater.
    Restarted computer.
    Problem Occurs.
    9. Restarted the computer in safe mode. Changed the login preference pannel to automatically log into the administrator account. Restarted computer, waited for the blue screen, then walked away for about 2 hours with the computer on blue screen, hoping the system was loading or doing something.
    Problem Occurs.
    10. Put in the TechTools Pro CD, hoping to run some tests on the video card from the cd. When booting from the CD OS...
    Problem Occurs.
    11. Enabled Root user. Logged in as root and installed ATI Displays 4.5.6 from there. Restarted computer.
    Problem Occurs.
    12. Shut down computer and installed old video card.
    13. On an internal hard drive in the computer. Wiped the drive and formatted it. Installed 10.4.1 on the drive. booted up into the drive, installed ATI drivers, shut down computer, installed 9800 pro video card, booted up.
    Problem Occurs.
    With the new 9800 for Mac ATI card with 256mb:
    With original card, install drivers, repairpermissions, shut down, install new card
    Set to restart in single user, give 5 min to see if ATI monitor startup item in user starteputems loads
    Hooked VGA & DVIt in together, both showed blue screen
    Reset NVRAM via open firmware
    Reset cuda button
    Take battery out, wait at least 10 min, re-install new battery, press cuda button
    Reinstall ATI update 4.5.6
    Reset nvram from open firmware
    In ATI control panel, selected 'Force Single Display Operation'
    Change display scaling to 50%
    Download latest Mac OS update from apple & reinstall
    Help?

    I get dizzy just thinking about it.
    I have tried installed a brand new OS, 3 different times on a different Hard Drive, still the card doesn't work.
    I had one person suggest that it may be the card is not communicating with the OS Window Drawing module? (excuse my ignorance of what that is really called. I just know there is some program, possibly in the kernel, that is responsible for drawing out the OS windows.)
    How can we rule out that it is a bad AGP slot?
    •The slot works fine with my 9000.
    •It works in safe mode with the 9800.
    •I have installed a brand new OS, three different times, still doesn't work.
    •I have used Apple Hardware test to test my hardware, the AGP slot didn't report any problems.
    I am assuming that the AGP slot is working. Although I worry about it a bit, because by now I have swapped cards in it about 50 times in my troubleshooting.
    Here is a link to a complete list of everything I have tried:

  • Digital Audio G4 and Radeon 9800 Pro

    Has anyone had the same fuss w/a Digital Audio and ATI Radeon 9800 Pro Mac Edition? Been through about 5 cards (lost count somewhat) and constantly getting a display of the video card (with its power connector flashing red) on a black screen. Only by opening the box and reconnecting the power connections, and sometimes reseating the card, do I get successful results, with the Mac booting properly.
    No other card (others that I use do not require an additional power connector like the 9800 does) seems to have this problem; all boot properly.
    There is a Sonnet 1.8 Ghz Dual CPU upgrade, 2 internal hard drives, a raid card, and FW 800 and FW 400/USB2 cards, but additional power connections for those have been unplugged. I'm good with letting any external devices run on their own power.
    Thanks much, to anyone that may have a suggestion or a solution.

    Hi-
    With regards to the connector graphic, this invariably means that there isn't power connected.
    State the obvious, but, have you tried pulling power from a different connector? Maybe try a new extension........ Molex connectors can work loose from the cap, and slide back when attaching to a device. This would give the appearance of being connected, though in reality, otherwise.
    Have you tried without any of the PCI cards installed? I wouldn't want to remove the processor, either, though the dual does pull some power at boot. The DA PSU, however, should be able to handle both the processors and the 9800..... unless the PSU has a weak 12v/5v/3.3v rail....
    Pulling the PCI cards will clear up whether or not the problem is with power in the PCI bus.
    As for posting a picture, you need to host the picture at a site like Photobucket or Imageshack. Then, place a link (produced at the host site) in your thread.

  • Radeon 9800 pro too hot

    I am running a radeon 9800 pro on my msi board and even tho i am not running games, it gets too hot to the touch. I have 7 case fans, power supply fans, cpu fan and video card fan. I am running latest catalyst drivers and read that they can make the card run hot, has anyone confirmed this? how do I check the temp of my video card?

    If you have artifacts it will be to hot, otherwise it's OK.
    7 casefans is overkill btw. I have 1 80mil fan that keeps my case below 35C eventhough my computer is stressed all the time.
    IF you want to make it really cool, get this cooler: http://www.arctic-cooling.com/vga2.php?idx=41
    It blows the hot ait out of the case in stead of circulating it a bit below the vid.card.

  • ATI/Radeon 9800 Pro 128 AGP 4x/2x in Gigabit Ethernet dual 450 PMac G4

    Hi,
    This is my first time posting to these discussion group... I've been going through related threads and have not found an answer to my problem...
    I have a Gigabit Ethernet dual 450 G4. Awhile ago I upgraded the processor to a Sonnet 1.8ghz so I could run Leopard.
    I just bough the ATI/Radeon 9800 Pro 128 AGP 4x/2x video card. I researched around and that seemed to be a card that would work in my machine. I even read a review on Amazon where someone had also upgraded to the 1.8 processor used this card with no issues.
    I do have an older monitor - Apple Studio Display CRT with the ADC connector. So I also bought the Apple DVI to ADC adapter kit.
    I installed the card and do not get any picture at all - I believe I have installed everything correctly. I'm pretty sure I can hear the fan on the video card in the machine. The monitor is getting power from the adapter since the button lights up when I press it - but it does not stay lit -- the monitor never turns on. Using my old graphics card the monitor makes a little "beep" when it turns on.
    In reading the other topics I am wondering if it might be a power issue? According to Other World Computing's profile my machine has a max of 220 watts. Although they suggest this video card as one the will work in my machine.
    I have disabled the hard drive that came with the machine (too small) and am using two Maxtor hard drives that I added - one ATA (120gb) and one SATA (500gb) that is connected to an SATA pci card. I also have two additional pci cards with usb 2.0/firewire ports.
    In looking at the topics here I came across the link about taping the 3 and 11 pins on the video card. Even though the card I have is 4x/2x not 8x I thought I'd give it a shot. That did not work either.
    Any help you can give would be greatly appreciated.

    I don't wish to sound redundant here, but I've been reviewing the vendor's page:
    It's OK- I don't mind beating this dead horse....
    The maker says such to protect themselves from possible claims that may arise due to over loaded systems and power problems when their card is installed in said system.
    Of course, 300w would be nice, but they didn't even specify the PSU rating a couple years ago. The Sawtooth, with it's 237w PSU, used to be listed as a compatible machine for the 9800...... They just didn't consider how far a Sawtooth might be modded.
    Within reason, the early G4's (Sawtooths) are capable of using the Radeon 9800 Pro. The GE has the same 338w PSU as the DA (they are interchangeable), so there is plenty of power for the 9800.
    One thing to remember, the requirements of the ADC port of the AGP slot are removed by using a non ADC card. This really changes the calculations of the power available.
    It's kinda' a long post, but, if you care to get ALL the details, check the following:
    http://discussions.apple.com/thread.jspa?messageID=7065653&#7065653
    I think you'll be satisfied with the explanation.......
    Which leaves your second, and very appropriate, point.
    The main enemy of all, though, isn't power. Heat is the biggest concern.
    Reducing heat/increasing cooling by using a third party fan on the 9800 is highly recommended. The 9800 is a hot card, and the stock fan is prone to early failure.
    Adding additional cooling to remove the extra heat produced by the 9800, by using an exausting PCI fan, will also help the PSU provide adequate voltage to the system, by reducing the amount of hot air moving out of the PSU.
    Super heated air moving through the PSU reduces the cooling ability of the PSU. A hot PSU doesn't produce reliable power.
    So, add the 9800, add some cooling, and enjoy!

  • [Athlon64] MSI K8T NEO-V : incompatibility with ATI RADEON 9800 PRO

    Hi,
    I read all the subjets on this forum about Radeon problems with MSI K8T NEO motherboard.  Most of the peple can't use their graphic card in all situations.
    My PC is :
    -MSI K8T NEO-V
    -AMD-64 3200
    -Power : 400W
    -ATI RADEON 9800 PRO
    -1 Go DDRAM (2x512 in single channel)
    -Hercules Digifires 7.1
    I bought a new MSI K8T NEO-V with AMD 64.
    The problem is that I can't use the computer in the games with AGP 8X even if I try to enable-disable all the options possibles in BIOS and Windows (fast write ...) : The computer freeze (screen disapear as if there was no video signal), reboot or return to Windows disabling the accelerated mode.
    But in AGP 4X, all the game run without problem with all setups of BIOS !!!
    I tried all the drivers (the new and the old drivers).  Even if all are updated, it freeze.
    There are no BIOS update for my motherboard. I saw that some people had BIOS update for compatibility with some Radeon cards ...
    So, I don't know how to repair the problem because AGP 8X is AGP 8X and not 4X, and my Radeon run fine on other computer, and nothing say that Radeon 9800 pro don't run on this motherboard.
    Does someone have the solution to make it work ? Does a new BIOS or driver update exist somewhere for Radeon cards ?

    What Bas said about 30+ amps on the 12v rail does have merit. Even if you don't use it now there may come a time when you want to upgrade the system and certainly you won't want to buy yet another PSU then. A High end vid card now takes almost as much as the CPU to operate. Now days the 12v rail is the most important. Past systems regulated everything off the 5v railk and 12v was used mostly for powering drive motors. Now though the MB's use the 12v line to regulate all the voltages for the CPU, Chipset and other features as does the Vid cards. 3.3 volt lines are used for memory so we hardly use any 5v nowdays.
    You have an older viod card and that does not eat much 12v but if you upgrade the most likely peice will be the vid card. You could go through this whole thing all over again if you are not careful to plan for that now with a new PSU purchase.
    If the computer shop gives you a bunch of bull about power needs havbe them stop by the forum and we can help set them straight on this. There is more than enough data from MSI and historical data here that suggests that 16a on the 12v rail is certainly not enough. Hey I am not trying to sell you anything. I am just trying to help you get it right. The computer shop is the one trying to sell you something we just feel they are selling the wrong junk.

  • G5 graphics card error: ATI Radeon 9800 pro

    Hi there,
    The display on my mac has all of sudden gone haywire, there's bars across the entire screen that keep on changing colours/flickering etc, and when I try to drag open windows they become blocks of noisey colour.
    So far i've tried resetting PRAM/NVRAM, ran the hardware test which picks up an error on the VRAM which is: 2ATI/1/4:113-A1440; ;16 (I think, it's very difficuilt to read properly), also pulled the graphics card out, given it a bit of a dust etc and put it back in to no avail. I've also tried plugging in another monitor which had the same problem.
    I'm assuming my graphics card's fried, but I wanted to check on here to see if anyone had any other ideas. I'm slightly wary about splashing out on a new card when i'm not completely sure it's the card that's the problem, it could be the logic board for all I know. Also not too keen in taking it to the apple shop as it'll be away for up to two weeks, and I really need a working machine just now.
    My specs are G5 single 1.8ghz, 512 ram, ATI Radeon 9800 pro card (not the special edition)
    Apologies for the long message, and for any spelling mistakes as I can barely see what i'm typing, any advice most appreciated.

    I would suggest first blowing compressed air all around the inside including logic board and video card (if you are adept at removing the card and reinstalling the better, careful not braking the AGP clip at the end of the slot that latches into the end of the card). Also keep the can upright at all times. This should help dislodge dust that build up over time and may cause overheating and unusual operation.
    Then run Apple Hardware Test disc that came with your computer and run the extended test. It should at least help give you an idea if it's the logic board and/or video card. It's not 100% failsafe, but worth a shot.

  • G4 450 AGP to Radeon 9800 Pro upgrade low down.

    I have been looking to upgrade my G4 450 AGP graphics card. I'm running 2-22" ViewSonic 2235's at 1680x 1050 w/ Rage 128 AGP and PCI cards. I've learned that this G4 has 2x AGP slot and few cards fit, namely ATI's Radeon X800 XT or Radeon 9800 Pro, both Mac Editions. Price eliminates the X800. 9800 comes in 128MB or 256MB flavors. Questions: 1. Is there any real advantage to the 256MB version aside from dual DVI output vs 1 DVI 1VGA? 2. Having seen max resolution at 2050x...; Is this resolution per dual monitor channel or will I have to lower my 1680 to a 1024 per screen. Thanks folks.

    Hi-
    but why do you need more on the G4, the machine can't handle any software that requires 256MB of video memory anyway.
    The only one who would say that, is someone who has settled for less.
    There is a BIG difference between the other cards, and a 9800, even on an "old" machine.
    I see all kinds of improvements in applications, the OS, system performance, etc., as compared to my old 9000 (64mb). The difference is night and day!

  • Aperture and ATI Radeon 9800 Pro Mac Special Edition

    I have noticed a few people on this board have the ATI Radeon 9800 Pro Mac Special Edition (256MB- G5 only) listed on thier specs on the bottom of posts
    so I was wondering what your experience using this card is like with Aperture, even-though it I realize that it is not the current top of the line card ?
    How about a rating from 0 to 5 stars where 5 would be the best currently available.

    P.S lets not get into a p**** match over what IS the best video card for Aperture; I am just looking for subjective views on THIS card!

    I have just the card you mentioned.
    I think how happy you'd be with it depends on what kinds of files you are using. I work with TIFF files because my camera is not supported, and performance with those is better than with true RAW files.
    I generally do not see much delay but a few adjustmnet tools (Shadows & Highlights & Spot/Patch) can get a bit pokey.
    Honestly if I were upgrading my card all over again I would bit the bullet and get the x800XT, which I am mulling over even now... I was hoping it might drop a bit more in price but it does not seem to be doing so.
    If you want an absolute rating I guess I'd give it three stars, though again that is with the files that I use. For other larger RAW formats like D2H files and such, I think it's more of a two.
    One last thing to note is that I have not tired other raw formats since the update, so it might be upgraded from a two... I was waiting to see what kind of speedup Aperture 1.1 offered in addition to just the system update. I'll report back when that update comes out.

  • K7N2 and Radeon 9800 Pro Prob..

    I work at a computer store in Killeen texas and am having an issue with the K7n2 Mobo. When we use a Radeon 9800 pro from ATI, we do not get video on every boot. The system will go itno windows but will not show a post screen or windows. This only happend with version 3.4 of the bios. We downgraded to version 3.3 And the card worked perfect. Their is a new 3.5 Bios. Was wondering if I should upgrade to this bios or Leave it at 3.3. By the way....We tried three other K7n2 boards and two different Raddy9800s. We also had a similar prob with the All in wonder 8500. And again version 3.3 of the bios worked fine. Any Ideas....

    leave it at 3.3 as its not changed
    but its not all boards and all ati its wierd
