Mac Pro :: Using Red Diagnostic Lcds On ATI Radeon X1900XT
Oct 14, 2009
My ATI Radeon X1900XT graphics card keep tripping out leaving a black screen The card itself has a red lcd light visible on the card when the screen is not working
The card is in an 8 core mac pro and is running a 30" ACD.It started a while a go before installed Snow Leopard but happened very infrequently
Have installed snow leopard and added two new dvd drives and I now have these blackout nearly everyday.
Have found info on ATI's website about the Radion HD 4870 suggesting the LCDs indicate a faulty power supply or even disconnected power leadsthe same thread also mentioned overheating could be the cause a of the red light.
anyone know what the Red diagnostic lcds on Mac ATI Radeon X1900XT mean.
Extra info: The two DVDs I have added I had to replace the data cable as I damaged the original
to do this meant a total strip down, while I was there I added two sata data cable threading them through connecting to a new sata drive and leaving one spare for the future.
The DVDs work perfectly, could adding the sata cables have an effect on the power supply.
Having to remove the ATI Radeon X1900XT, I am sure the cables are seated correctly, should it matter which cable is connected to each connector on the motherboard.
There is a thread on apple website about this black screen, all describing similar problems but relating this to Snow Leopard and some sort of video bug.
No answers on that site and no one else seem to have the Red diagnostic lcd
I have newest a Mac Book Pro 15". I would like to find a small and powerful adapter or something small device that can hook up two large 24" or much larger to my Mac book Pro. I saw some adapters in the magazine or some place the website. I forgot where to find. I will use them for Final Cut Pro editing as viewing.
I am running a Mac Pro 2,1 and just had my x1900XT die. I know the 4870 isn't officially supported but was told on many a forum that it would indeed run. So I purchased a new Mac HD 4870 card and put it in yesterday. Seems to work fine and the user interface is snappy. However when I run Xbench and just the Graphics benchmarks I can see that I am actually scoring on average 30 points slower than when I was running the X1900! What is going on here? Is the card not being fully utilized due to it not being fully supported on my Mac Pro 2,1? Is it under powered? I plugged in the provided 2 power cables directly to the 2 connectors on the board. However in Cinebench 11.5.29 I scored a 24.96 which is something I couldnt run with my X1900 XT. Anybody have any answers? Extremely frustrating to upgrade to downgrade. Thinking about returning it and buying the officially supported HD3780. I work in Pro Apps all day long and need a good performer.
Ordered from eBay Graphics Card Upgare (Ati Radeon x1900xt / Part# 102A5202752 000006) for my new Mac Pro (early 2008). It came in white box with Apple logos. Attached and powered it but I get only "No Signal" on my monitors (LCD: Eizo FlexScan S2401W and Samsung SyncMaster 225BW). Tried different cables: DVI-D Single-link, DVI-D dual, DVI-I Dual and VGA+Apple DVI-adaptor - no effect.
It seems like the new card isn't recognized properly?
i have been having a lot of problems with my airport on my imac it disconnects and is unable to connect to my networks for like an hour then starts working - this happens randomly can you tell me how to run a hardware diagnostic on my imac before i take it to the genius bar?
I've been experiencing a variety of problems with my peripheral devices. At first it started with my monitor and I thought it was going out... it was having lines (darker lines, like flickering) all over the screen... but then I realized this happened when I plugged something into my computer... so for example if my external monitor is on, and I plug in my firewire soundcard it starts to flickr...
Then it started to do it when I would plug in my printer... now if I plug in my firewire soundcard my monitor turns on and off... and I'm having sync issues with my soundcard.
I wiped my computer, reset the SMC and the PRAM and NVRAM. How do I test if my mother board is crapping out?
So I had to take my macbook pro into the genius bar recently to replace my battery and they ran diagnostic tools from a nano. Anyone know how to get a hold of these tools or what they are?
I have looked everywhere, including under the right speaker. Have removed the display ... they are nowhere to be found. But I know they're hidden here somewhere!
after a lot of testing we have managed to clear everything around the topic of flashing stock PC X1900XT/512Mb (256Mb is NOT working!!) with MacPro EFI ROM. Thank you all guys at Strangedogs! It WORKS prefectlly! Ofcourse flashing card with MacPro EFI rom reenders card useless in regular PC, you have to flash it back with original bios to make it work in PC again.

I'm very happy with my 2010 MBP 15" i7 -- very slick little piece of kit!
However, there have been a few cases recently where I had to force a hard-shutdown of the laptop (holding the power button for 3 seconds). This is not because of the actual MBP per se, but because of some software that froze and wouldn't let me force-quit them.
Anyways, I'm wondering, since I had to hard-shutdown several times recently, if I should check my OS for any weird happenings? I always, always do Apple > Shutdown, but I've been forced to use the power button recently.
Is it possible that a failing I/O board would not show up as a problem in Apple's hardware diagnostic test? (from disc 1 of those included with the computer). I'm specifically referring to the Left I/O board, which handles the left ports, the a/c adapter, and part of the wireless connection. My battery just fried and now my airport card isn't working, and after trying everything, I think I may have found the issue.
I have a 21" i3 3.06 Ghz iMac. I got it in 2011 and the warranty has expired.
Anyway, I notice that every few months after clean installing Snow Leopard, my hard drive would be come corrupt necessitating a complete reinstall of SL again.
This occurs every few months. The OS is up to date, no malware, no weird software of anything installed. Basically, everytime I boot up, it'd take about 5-10 minutes as it does the gray screen with the spinning wheel with a progress bar at the bottom of the screen.
I have tried repairing permissions and scanning for errors using disk utilities within SL and via my SL install disc. However, I am unable to repair disk because it is corrupted.
Is there any other HDD scanning tools that I can use to see whether or not my hard drive is defective?

Just picked up the adaptor today and thought it was pretty much a no brainer: plug it in, it works. Not in this case, it keeps getting a self assigned IP address and I can't connect to the internet-although there is a green light next to the ethernet adaptor in System preferences. I have an Airport network set up as a normal scenario. I bought this adaptor only because I am about to take a trip and the hotel only has ethernet in the rooms. I've tried using the diagnostic tool, but it keeps hanging and crashing.
I recently bought an used iMac (was purchased new in feburary 2009) in which I knew the screen was not showing any video when I bought it. ( I was okay with that I thought I'd give it a go at fixing) well the problem seems to be within the LCD itself. When I hit the power button I hear the chime, fan spins, and the hard drive does it's thing. I ended up taking the casing off the iMac to where it only shows the bottom half of the insides underneath the LCD. My question is now to diagnose what exactly is wrong with it by using the 4 led lights. I have searched the forums and the Internet up and down for which ones mean what but I have only found out information on older iMacs. When my iMac is off (still plugged in) LED 1 is on. When I turn the iMac on LED 1,2, and 3 are green. Which that leaves the 4th LED not being lit up at all. I suspect this has something to do with the iMac not showing any video but as I said I am not sure because I cannot find any information on it anywhere.
I'm having a periodic problem where my network will timeout. Once that happens, I'm unable to connect to the network again by choosing the network. When I run the diagnostic, only the Wi-fi light is green. If I use the assistance, it tells me the password is incorrect even when I know it's correct. I will always connect for a second or two before timing out or being told the password is incorrect. If I purposefully type the password wrong, I'm immediately told it's wrong without the hesitation of connecting for a second. Does anyone have any ideas of what is going on? I eventually get connected but only after going through a laborious process of either created a new network or deleted all the Wi-fi information. Even then, the process is temporary.
My iMac stopped booting. The fans and hard-drive spin up but the screen stays black and I can hear that the hard drive isn't been read after the initial spin up.
I decided to open it up to take a look at the diagnostic LEDs to see if it might help me diagnose the problem (the most obvious failure is the logic board). I can't find the LEDs anywhere, where are they? Does my iMac even have diagnostic LEDs?
The other possibility is that I can't find the lights because they aren't lighting up. The fans, the hard drive and the CD drive all spin up fine so at least I know that there is some power running though it.

I got an ATI Radeon 9600 Pro All-in-wonder in a box of computer junk. Actually, besides a stick of PC3-6400 memory, it was the only thing that wasn't just an empty box or instruction manual
I have a few question for people who have upgraded to the ATI 5770 form the 8800GT.
It looks looks the install is pretty straight forward. But what type of performance upgrade can I expect? I use manly Photoshop, Lightroom and X-plane. Are there any hidden got-you's?
I have a 2010 Mac Pro currently using the 5870 graphics card to run a 22� monitor. However, I am going to add a second 27� screen to my setup. I do a lot of heavy 3d modelling so GPU power is very important. I spend hours and hours panning and zooming in dense models so I would like to dedicate the 5870 power to this, rather than it running dual monitors.
I have read that you could use a GT 120 to drive extra monitors but I�ve also heard really bad reviews for its performance, making it really painful to spend an extra �120 on it. The 5770 is �80 more and has a lot more power than a GT 120.
Is it viable to use PCI Express Y-splitters to run a 5770 and 5870 together? If so how would it work? What are the dangers in doing this?
I have done some research and apparently you can use PCI Express Y-splitters to run two high-end cards on the Mac Pro, though, I couldn�t find a lot of info on the subject. I�m not really computer literate but I�m willing to do some moderate internal tinkering in order to run two decent cards (which is really surprising for a Professional computer).
I'm searching for upgrade video cards for my dual 533Mhz digital audio G4 PM. I've noticed that there are several sellers on eBay selling ATI Radeon 9600's and claim they work on PM G5's as well as PM G4's. [URL]. Could these cards just be stock Apple cards pulled from a G5 that happen to work in a G4, or are they altered or flashed PC cards that work on G5's and G4's. Is it common knowledge that you can pull a 9600 out of a stock G5 and use it in a G4?
has anyone installed 2 of the ATI Radeon 3870 (mac edition) cards and get crossfire mode to work successfully in XP under bootcamp? I've been trying to for a few days now with no luck!
The drivers for bootcamp on ATI's site won't install on my machine for some reason and when I use the normal xp drivers (successfully) I can't get the crossfire option to show up in catalyst control center.
Also, in the catalyst control center, it only shows the primary card as enabled and says my other is disabled. However, they are both enabled and working just fine according to the device manager.
I'm using OS 10.4.11 on a first gen mac pro. Would I have to upgrade my OS or will this card work on it. If the card is not compatible with my OS what cards would be besides the ATI Radeon x1900.
I got an MP09 with Apple HD 4870 512MB graphics card some time ago and while I enjoy working with Mac OS, I also enjoy playing games. At the Mac OS side I don�t really play games or do much heavy 3D stuff but on the Windows side then I play. I noticed that the graphics card kinda get�s hot, not in amounts to worry but still. Catalyst Control Center states the following: 79�C while at 70% load with fan at 20% windows 7 x64, Catalyst 9.12 I would like to tune the fan to 33%. Is there a way to do this? I enabled Overdrive and checked manual fan speed, which doesn�t work (known bug). Then I edited an profile and loaded it, still not at 33% fan speed. I also tried Speedfan to tune the PCI fan of the MP but it doesn�t show me the fans of the MP.
