Symptom: iBook typing by itself. Diagnosis: Video Ram Error

My ibook types by itself sometimes.
If I run the Apple Hardware Test when the computer is fine then the computer will pass the Apple Hardware Test.
But, if I run the Apple Hardware Test when the computer is malfunctioning then the computer will fail the Apple Hardware Test.
Here is the error message:
Video RAM Error detected
**ERROR*CODE***ERROR*CODE**
2ATI/2/4: 113-xxxxx- 1 42
**ERROR*CODE***ERROR*CODE**
Is there any genius out there who has a solution?
I already took my computer to an authorised Apple Service Centre, they told me that I should replace the logic board.
I live in a developing country. A new logic board is too expensive for me.
ibook G4 Mac OS X (10.3.7)

I'm guessing you actually have two problems. A video RAM problem and a keyboard problem. I can't believe a video RAM problem would reveal itself by typing. The keyboard can be replaced easily, it's a user-replaceable part. I might try to get that replaced first. It shouldn't be too expensive. However, this will not fix the video RAM problem you've detected. You will need to replace the logic board to get that fixed.

AHT Video Ram Error

I have been having a string of kernel panics and AHT v1.2 detected a video RAM error "disp/13/2". In a previous post, it was suggested that this message meant that many things were fried and that a new computer was the best option. Has anyone successfully repared this problem, and how do you do it?

Unfortunately, AHT's very cryptic messages are intended to benefit Apple technicians, not ordinary civilians. That said, any message about a video or display problem is bad news, because it probably means replacing either the logic board or the display, and each is very expensive.

Video RAM Error code disp/13/2

Hello again
Does anyone knows what this means? And if so, how can I fix it?
My display has been going funny for the past two weeks now and keeps crashing. After I did a hardware test, this came up next to the video RAM:
Error code disp/13/2
Now I have no idea what to do next?
I'm desperate, please help.

That means that you need to take it into an Appple Authorized Service Provider. It is not user servicable.

Video RAM Error Detected

I've been having major problems with my PowerBook G4 (12", 1.33 Ghz, 1.25 GB RAM, 60 GB HB, Tiger). I just ran the Apple hardware test again. It said that there is a Video RAM Error Detected. Here's the Error Code - 2NYD/1/4: 2086
Does that make any sense to anyone?
Thanks!

It means you need to take your machine in to service if it doesn't fall under these programs:

If the cost is too high, one of these companies may fix it cheaper:

Video Ram error detected: 2NVD/1/4:0x6" -?

Dear Apple users,
Apple Hardware Test confirmed that I have the following error under Video Ram:
Video RAM Error Detected
Error Code 2NVD/1/4:0x6
Does anyone know what this mean? Do I just get a new video card? Or is this error related to the logic board and needs a major replacement of the motherboard?
Thank you for any advice beforehand.

Hi-
The error is referring to your graphics card VRAM, not a problem with your logic board.
Do I just get a new video card?
I would say Yes.

Video Ram Error Detected Question

Had my screen lock up and when I ran Apple Hardware Test I received a VIDEO RAM ERROR DETECTED - Error code 2NYD/1/4:2122
Scrolling is all messed up, tried reinstalling system software but nothing seems to help. Only starts after quite a few tries.
Do I need to take in for service or is there a software fix?

Welcome to the discussions Eugene.
If I were you, I'd take it in for service. It sounds like a hardware problem that a software update won't fix.
I hope it works out for you.

Hardware Test: Video Ram "error code 2NVD/1/4:119" G5 2.7 NVIDIA 6800 Ultra

Wondering if anyone has experienced this . . .
My G5 started displaying rows of chevron shaped artifacts a few weeks after upgrading to Leopard, Bought a used replacent card and it seemed to fix the problem for a couple of weeks then too started displaying the artifacts, ran the Hardware Test on both cards and both had Video Ram error code 2NVD/1/4:2119
I'am reluctant to buy yet another card untill I'am sure its not a Leopard Issue. any ideas?

I need to do more troubleshooting of my problem before I trying to reflash I think . . .
the other day I had a friend install both my original card and the newly purchased "used" card in his G5 and he also got the error codes on both of them. Brought them home installed the replacement card reset the SMU and PRAM as I've done many times before and got the G5 up and running (after several reboots) no artifacts seemed to run perfectly for a couple of hours anyway when I tried restarting and then the problems returned, gets to the grey screen with the rows of artifacts then stops, screen goes black then the fans start slowly spooling up to max RPM (most likley from a kernel panic) logs show;
"Apparent UniNorth Hang: AGP Status"

Video Ram Error

Hi All,
Wondered if anyone could advise me?
I have PowerMac G5, 2x 2Ghz, 2.5GB DDR SDRAM.
I've upgraded to 4.1.9 and keep software up to date.
All ran perfectly, until out of the blue, my screen started displaying artifacts. Example:
ftp://tonyg3d:[email protected]:21//tonygold3d.com/public/Picture.png
(Copy link into browser)
Photoshop seems uneffected, but 3d software runs, but is distored as example.
I ran disk warrior (repaired and fine) I then ran, the Apple Hardware Test from my install disk. I got an error message from the Video Ram; 2 ATI/I/4: 113-A14401-117
Is there a way to fix this or do i need a new Video Card?
If so, i was looking at ATI Radeon X1900 XT Graphics Upgrade kit. Is this compatible with my machine?
Thanks in advance,
Tony.

Hi
If the graphics card has a fan attached, it may be worth checking that it isn't sticking or clogged with dust etc, just incase they're heat related artifacts. Failing that though, assuming it is a geninue hardware problem with the VRAM, I think the only option is to replace the graphics card.
Compatible cards depend on whether you have a dual processor 2GHz G5 or a dual core 2GHz G5. The former (dual processor) has an 8x AGP graphics card slot, making the Radeon X800 XT the only real choice. The latter (dual core) has a PCI Express graphics card slot, making the Radeon X1900 the only real choice. You can tell them apart by the number of ethernet ports on the back - the dual processor models have one ethernet port, the dual core models have two.
Unfortunately Mac compatible graphics cards seem to be in short supply at the moment, seemingly because they're being redesigned to conform to the RoHS (Restriction of Hazardous Substances) directive.

Video Ram Error Code

I ran Hardware Test and got an error for Video Ram. 2ATI/1/4 113xxxxx117
Can I replace the Video Ram myself? If not, how much does a repair like that cost? RAM is guaranteed for life, right? So how about Video Ram?
I am getting lines around icons and the cursor. It is imposible to watch any videos in iTunes or FrontRow without enormous graphic interference. Like a really bad connection on your TV.
Thanks.

The video RAM is part of the motherboard. It is not something that you can replace yourself. Unfortunately it means that you need a new motherboard.
FYI, you should ask future questions in the iMac G5 discussion area since you have an iMac G5.

Bad Video Ram? N560GTX-Ti Twin Frozr II

I noticed that in games, and in youtube videos, there would be pixellated patches that were off-color. I noticed some that were tinted red, and others tinted yellow. So I opened up GIMP's color picker and indeed there were two off-color lines of improperly tinted colors forming an x in the middle of the color picker. Because this appears to be a purely display problem, I couldn't take a screenshot of the problem, so I took a photograph of my monitor.

The refresh distortion makes it a bit hard to see, but there's definitely an "x" shaped distortion running through the center.
Now that I'm halfway through writing this response, however, the problem seems to have spontaneously fixed itself. It's been only a few hours after I first noticed it. I'm wondering, could it be related to some other problems I've been having? I've been having issues on and off for the past few months. For example, after reading this article, I've seen all of the problems illustrated in the first three images at least once. I've seen much fewer problems after getting brand new drivers a few months back, but I've still had problems here and there. Usually it'll work fine, but occasionally the screen will freeze for two seconds during a game, then all the textures in the game will shuffle themselves around. At this point, spiking sometimes appears, and the problems will persist until I either restart or the computer crashes.
This card is only a few months old. Am I right in thinking the video ram is defective?

Can you show how it should look to compare it to yours?
Also it could be some kind of monitor issue, have you tried with other one?
I apologize that imageshack seems to have drastically lowered the quality of my images. It does seem very hard to distinguish between what's refresh distortion from taking a photo of a computer, what's jpeg artifacts, and what's the actual issue, but I assure you the problem is still visible.
Here's how it should look
http://img148.imageshack.us/img148/3350/picture003wt.jpg
Here's a copy of the original picture with the 'x' shaped lines emphasized. I have drawn arrows pointing to the problem, which manifests as two straight diagonal lines forming an 'x' across the color picker.
http://img42.imageshack.us/img42/3558/linesx.jpg
I'll point out that this problem appeared to be linked to specific colors. I noticed it in both 2D images and 3D games. The photo is just there to show that with all the available colors displayed on a color picker, the problem manifested itself in a distinct pattern relative to some colors.
And no, I haven't tried it with another monitor. Like I said, the problem spontaneously fixed itself halfway through writing the original post so I couldn't test it. I'm posting here mainly because it's the third video problem I've seen so far that's been listed in this article as a symptom of bad video ram. Of course it's hard to isolate these problems because they seem to come and go. Occasionally it'll get really bad, then after a restart it'll be fine for a week or two.

Also check cables and connections, especially if you use VGA - digital cabling shouldn't be impacted.
I'm using a DVI connector, so no VGA.

Ibook is restarting itself and will only load a blue screen

so a couple weeks ago i was having issues with my ibook and safari..safari would keep on freezing and or quit on its own..i thought my software was out of date so i went and got Tiger...when i went to install tiger i was unable to use the upgrade and the archive and install feature, thus leaving me with erase and install...so after deleting my hard drive and installing tiger i ran into more issues with my ibook...ive been trying to do software updates but half way through the download it will freeze up thus making me force quit the program and download...then my ibook would only load the blue background of the desk top but not the icon for the hard drive or any of the things on the expose..in attempting to get into disk utilities the ibook would reset itself...finally, when i tried to start up in safe mode i was only able to get to where you type in your password and no further than that...after hitting enter the password window would just open again...with all this being said..can anyone help me with this issue?i am fearing that it could be the mother board or even the hard drive but about two years ago i had my mother board replaced...so i duno whats going on

Some iBooks (like mine) had a separate disc with the Apple Hardware Test--others had it on one of the install discs but I'm not sure which one. It sounds a lot like you might have hardware issues of some kind since reinstalling the OS didn't fix the problem. I am assuming that you don't have easy access to an Apple store where someone at the genius bar could possibly help you come up with a diagnosis. Also, I am assuming you actually erased your hard drive rather than deleting it as you said in your post.
You might want to check and see which discs you do have and determine what is missing. If Apple itself did the last repair and did not return the disc, you could talk to Apple Customer Relations and explain your situation and see if they would send you a replacement disc, as it really should have been returned. If it was done by someone other than Apple, you can still probably get a replacement but there will likely be a fee. And if you do by chance have the AHT, by all means run it.
Otherwise, you will have to appeal to the more knowledgeable and experienced members of the forum for help, but I believe you will still need the original install discs. If you have another Mac, there may be some other approaches that can be tried, but I personally have not ever done this so I can't really help with that.
Good luck!

IPad gone crazy, typing by itself. Replacement only option?

My iPad have never worked, 5-10 min after I started it it is typing by itself. Like a self playing piano. This video illustrates the problem http://www.youtube.com/watch?v=fkP0dfw598k&feature=related
So, do I have to return it or can it be fixed somehow?

Here's a longer thread on this issue:
http://discussions.apple.com/thread.jspa?threadID=2412750&start=0&tstart=45
Please at least arrange a phone call with Apple support. We need them to acknowledge this as a known issue so they will replace them under warranty. I have yet to get Apple to replace my iPad with this issue, because I can't replicate the issue at will.

Video Ram Questions

Ok, so obviously the Blueberry iBook Clamshell has only 4 MB of video ram in the logic board. This is clearly preventing almost any video playback, preventing iTunes movie preview/viewing, and eliminating the need for upgrading to a Combo drive, as DVD playback is impossible.
I know that the later model iBooks have logic boards that will play DVD movies, thanks to their increased video ram. It doesn't make much sense for me to replace the logic board with one out of a Indigo or Key Lime iBook, although if I find a working logic board for dirt cheap......it MAY be feasible.....
Is there ANY WAY POSSIBLE to (maybe via software...) allow the video chip to SHARE some of the system RAM to increase the video ram somehow, and expand the capabilities of the displays on these models? Or is there some sort of hardware method to increase video ram on the logic board?

No and no.

MBP Video RAM Defect?

I've been experiencing random kernel panics for the last several weeks and frankly have had issues for quite some time with regard to flakey performance of my mid-year 2010 MacBook Pro. It wasn't until I formally opened a case with Apple and brought it in to the Apple Store that I found out there is a known defect with my particular machine with regard to defective video RAM. They did the test in front of me and I saw the error message on screen.
Bottom line is, my particular MBP has a defect, known to Apple that I can't seem to find any published detail on.
Does anyone on this forum know about this and can point me to the specific bug/kb document?
Please let me know as soon as you can.
Thank you!
Jim

I got an update to your post in email but when I come to the thread it is not there.
This is what I got in email.
Thanks for pointing me to the article: TS4088 - it sounds similar but implies that the fix is addressed by software then states "If the symptoms persist after installing the update, select one of the service options listed in the Service Options section below." The issue I have is related to RAM according to the guy at the Apple Store and is only resolved by a Logic Board replacement and software updates don't help.
Its the closest one I've seen though, thanks!!
To me the problem is the same and should be covered even if you are out of the normal warranty. But knowing Apple that may not hold true as they have jerked around 2008 MBP owners for a REAL defective video card problem. Not allowiing the repair for free because it is either out of the 4 year period or the system has failed completely, because of the Vid card problem, and they can't get the code that says it is the vid card problem.
Good Luck and best wishes.

128 MB video ram on a macbook pro - enough to drive the new 30"?

128 MB video ram on a macbook pro - enough to drive the new 30"?
meaning, can it do this well???

Even 16 MB VRAM would be enough to display a 2D picture on the 30".
Depending on 3D usage you need much VRAM.
Unless you are using a lot of the latest 3D games or Apples 3D pro apps (Motion/Shake or something like that) 128 MB should be fine.
