Video/RAM Corruption

This has been happening for about a year now and is progressively getting worse.
This is not a software issue as it happens in Windows and Linux as well as OS X.
I managed to snap a screenshot of what is happening, this was right after a restart and is the only time I've been able to capture what actually happens using software.
It also happens in games, here is some corruption in World of Warcraft
Is this bad RAM and would replacing it fix it? I really hope it isn't bad VRAM or something worse.

It's likely not RAM or VRAM problems - but rather GPU problems. Whether or not you purchased the extended AppleCare Protection Plan, you should take your machine to your lcoal Apple Store or an AASP and have the problem diagnosed: that an an extimate to repair will cost you nothing.
If, however, the problem does lie with a faulty GPU the entire logic board will need to be replaced: this can be very expensive.

Missing video ram

I have a 1ghz Titanium G4 with the ATI 9000 mobility 64mb video ram. OSx 10.3.9 1gig ram
Recently I have discovered that the system profiler lists my total video ram as 32 mb. My overall game performance seems diminished when playing graphically intense games such as Unreal Tournament 2004.
This discovery seems to have occurred around the same time that I had a battery charging problem which I have since fixed. My system has also been suffering increasing freezes upon wake from sleep or screen saver.
I recently perfomed an archive/installation of my OS hoping that might restore some corrupted files in the system, but no luck.
Has anyone else seen this problem or know of a cause/solution?
Thanks.

Hi, pioche. A 1GHz Tibook certainly ought to have 64MB of VRAM, and if it doesn't, the only reasonable conclusion is that the missing half has failed. It's all soldered onto the main logic board, so the remedy is to replace the board. Of course another alternative might be to avoid asking too much of the remaining 32MB, and thereby save quite a bit of money. That's what I'd do if there weren't any other signs that might point to a larger failure of the LB, but it sounds as though yours may be on its way out. Have you run the Hardware Test CD that came with the Powerbook?

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.

Is it possible to use my ram as dedicated video ram on windows 8 bootcamp

i have a mid 2014 MacBook pro
8gb of ram
dual core i5
intel iris 5100 graphics
im using my mac for gaming and need some dedicated video ram, I saw other computers like asus or Toshiba that were able to boot into windows bios and change there ram as dedicated ram, bootcamp has no bios so im wondering if there any third party applications of something built into bootcamp that would allow me to change a setting like that.
thanks in advance

From http://www.intel.com/support/graphics/sb/CS-033984.htm
How is graphics memory allocated in Windows 8/8.1*?
The Microsoft Windows 8/8.1 operating system adds improved support for graphics, simplifying graphics, memory configuration, and management. As part of this new graphics memory management, the Intel® HD Graphics Driver leaves more of the graphics memory sizing to Windows 8/8.1.
W8+ report GPU memory differently as compared to OSX.
This is from a 2012 Intel HD4K running W8.1 64-bit. Notice the value of Adapter RAM versus what is reported in Screen Resolution.

Techtool deluxe on osx lion does not run video ram test

I ran Techtool Deluxe after having installed OS X Lion. When it gets to the Video Ram test it quits. If I disable this test all is fine. What's wrong with testing video ram on OSX Lion?
Thanks.

Same problem. I've been having a lot of weird issues ever since Lion. Safari has crashed about ten times in the last two days and my mac keeps logging off all by its self. It seems that Techtool Deluxe and Lion don't go well together...when it starts it says that it hasn't been tested with Lion, and they no longer include it with AppleCare, so it seems that apple has discontinued the application. I'd say that from here on out, Techtool Deluxe will simply be a memory of the past...so probably just don't use it anymore.

Video ram failure?

My 6 year old iMac/PPC running 10.5 may have died. Without warning the screen went blue, and nothing would change that. I did the Apple Hardware Test from DVD and everything passed, inc. video ram. I zapped the PRAM. I went to restart, the Apple logo and spinning wheel appeared, but then the screen went to a mottled white, and after a while black.
Any idea what the problem/solution may be?
Thanks,
JC

The tech seemed convinced it was a failed graphics processor, and not worth repairing. Does this seem likely/reasonable?
A failed iMac graphics chipset (processor and VRAM together) requires a total logic board replacement as the video hardware is integral with and soldered to the logic board. Therein lies the high cost of repair to which the tech alluded.
Is this a G4 or a G5 iMac? That might make a difference in the "fix or toss" decision process. The G5 is more capable that the G4 and would be worth having a little more money thrown at it.
If there is a compelling reason to keep this iMac (like mission-critical software or hardware that won't run on a newer Mac, then you have to give weight to the "fix" scenario. However, the G-sereis Macs are becoming more handicapped every day as web sites and developers focus on the Intel processor that Apple adopted nearly six years ago. You cannot upgrade the OS past 10.5.8 on a G-series, and new software seldom supports the PPC processor. Neither can you run the latest versions of Flash that is powering so many web sites.
So it comes to "what tasks do I do with this computer?" I used a nice old G4 PowerMac tower (circa 2004) well past its useful stage and just recently picked up a 27-inch iMac i7 Quad core as a refurb directly from Apple. I'm sometimes asking myself why I waited! I feel like I've stepped from a pushcart to a Ferrari.

G4 Quicksilver - Enough Video RAM to drive 20" Apple Display?

I have one of these with 64Mb Video Ram, but will it drive an Apple 20" Display? ... at what resolution?

It will support displays up to 1920x1200 (23").

Satellite 320 CDT video ram problem

Hello
I have an old Satellite 320 CDT laptop with a display problem.
It works ok but display is abnormal. It does special effects (moving zebra style, especially in 32 bits display mode).
The same problems happens with an external monitor.
I am looking for replacing the video ram IC because i'm nearly sure it is the problem.
First step i need to open the laptop. I've removed the battery pack, the hard disk and all the screws but i can't open it.
What is the correct method to do this ?
Second step, how to locate the video ram component ?

Hi Pascal
To be honest I think there is no sense in doing that.
The point is that your issue could be related to the faulty graphic card and the graphic card chip is fixed on the motherboard. Mostly its not possible to remove this chip and therefore the whole motherboard must be replaced.
I think its better to search a little bit for the similar notebook on eBay.
A second hand notebook would be much cheaper as a new motherboard for the Satellite 320CDT
Regards

Video Ram using windows

hy everybody i've got a question.
I recently bought a brand new iMac (27' 3,4 i7 4GB Video Ram 8GB cpu ram 1TB fusion drive). I need to install a win programm which needs at least 3 GB of video ram.
i tried with parallels desktop 8 but it said i can only virtulize 1GB of video ram.
i wonder if anybody got my same problem, should i use boot camp or any other program?
i can't stand to wait a mac version of that program or any other program, i've got 4 gb of video ram and i want to use them!
thank u very much and sorry for my not perfect english!
Apple rulez!

From what I know, that game doesn't require 3 GB of VRAM, so you should be able to install it on your Mac with Boot Camp.
First, get a 64-bit Windows 7 and 8 version, and follow these steps to install Windows > http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf Then, install the game

How do i repair video ram failure?

My imac 11,3 has been starting and running extremely slow. TechTooldeluxe shows that the video ram failed. How can i repair this?

if it's real video ram and not shared system ram working as video ram
then the memory chips are soldered into the pcb not something a non pro even if they bought the memory chips to replace with can do with a smd soldering iron

ITunes video purchases corrupting my ITunes Library

Got a season pass for this season of "Mad Men" - but thus far two of the downloads have corrupted my LIbrary and seem to be lost for good (along with the other episodes that were in the Library).
In both instances, when ITunes crashed, this alert message came up on the screen: +"The file "iTunes Library" does not appear to be a valid iTunes library file. iTunes has created a new iTunes library and renamed this file to "iTunes Library (Damaged)"."+ - but when I look for these supposed files on my computer they are nowhere to be found.
Now - I am pretty new to the ITunes store - I've imported some music from other sources over the years and never had this kind of problem so am wondering: do people just EXPECT Itunes to crash and so back things up a LOT? My computer is pretty old and does not have that much storage space - do I have to back up each one of these TV episodes from ITunes just to be sure I'm not going to have to re-purchase them from the ITunes store?
Do people have any other suggestions about keeping these videos from corrupting my Library files?

Fortunately for me, the folks at ITunes restored the lost episodes to me - but I would still like to know if anyone has any words of wisdom about what I can do to prevent this from happening in the future.

Video RAM problem

Since a few weeks my Imac has started showing some instable, annoying black dots. In addition, sometimes the desktop gets monochrome (but not all, only partially) and flashes.
I've tried to understand what the problem is. Tech tool deluxe closes as soon as it starts to scan the video RAM. Is it possible to reset the VRAM?
Thank you

. Is it possible to reset the VRAM?
No.

TechTools Deluxe (Re: Video RAM and reinstall)

I have the annoying screen inverter/logic board whine (yes I know this has been talked to death here), sometimes not so bad and sometimes I can hear it over a desktop PC is the bearing going out in one of the fans. I happen to be visiting family in a city with an Apple Store this weekend, so I thought I would talk to a real person face to face. Anyways, I ran the TechTools Deluxe CD that I received a week of so after I got my MacBook Pro. To see if there was anything else besides, my whine to mention to them and will you look what came up
Video RAM
Failed
Video RAM, as all components of your video circuitry, must be fully functional for graphics to be properly displayed. Damaged VRAM can cause missing bits, screen noise, system lock ups, or freezes. TechTool Deluxe tests the VRAM on the Macintosh main logic board, as well as some third-party video cards.
If the VRAM test should fail, try these steps in order and run the test again after each step:
o Quit all other applications.
o Restart the system.
o Check any recently-added hardware for proper installation.
o Run the computer from another volume (if available).
o Reinstall the OS.
o Contact AppleCare.
I have done everything except reinstall the OS and contact AppleCare.
Anyways I wanted to know first of all if anyone else had gotten this error and if so did a reinstall fix it? Secondly how hard is the reinstall, I come from years and years of DOS, 3.1, 95, 98, Me, and XP, and one thing all of them have tought me, is reinstalls are horrible, drivers don't work again, ect. So is OSX easy or should I just ask them to look at it this weekend?
Oh and the Apple Diagnostic on the OSX cd 1 says everything is fine.

Well the apple test (on disk 1 of OSX) states that nothing is wrong. Though I will test again when the temp gets high since some people had been detecting problems.
as for 10.4.6 I downloaded it the other day.
I repaired the permissions had a couple things that it corrected (I don't know if I posting them would do any good) Out of curiousity how to permissions get incorrect? I'm so used to the windows file structure and DOS before that that i am a little confused. The last apple used alot before this macbook was an old Applee IIE.
and the TechTools still says there is an error, every time I have run the test. Though there have been some differences when I reboot or turn of and wait a second and then restart.

How do I manage Video Ram size

Hello,
I would like to ask how do I adjust the size of video ram in OSX and windowsXP. I have read someone's post saying that it is not user changeable in OSX. if it is not changeable, when will it changeable to a larger size? How about in windowsXP? Is it also unchangeable?
Thanks a lot,

You are aware that video RAM is a physical factor while "OS X" or "Windows XP" are software operating systems. The system you use plays no role in how large your video RAM is. If you want to adjust your video RAM usage, go to the monitor control panel and change the resolution and color depht.
If, on the other hand, what you were trying to say was that some laptops that run on Windows allow you to upgrade them with physical video RAM, I guess it must be so. The Macbook doesn't allow this and uses shares video RAM which, to my understanding, means that it uses a part of the main RAM for video.
