Apple says that some of the AMD Radeon HD 6970M graphics cards used in 27-inch iMac systems with 3.1GHz quad-core Intel Core i5 or 3.4GHz quad-core Intel Core i7 processors could fail, causing the display to appear distorted, white. or blue with vertical lines, or turn to black. Systems outfitted with a potentially affected GPU were sold between May 2011 and October 2012.

There's now a replacement program in place, so if you own an iMac with Radeon HD 6970M graphics that's exhibiting any of the above mentioned symptoms, you can have it evaluated at an Apple Retail Store or contact the company's Technical Support for local service options.

Apple iMac

"If the iMac (27-inch) meets these requirements, Apple will replace the video card free of charge for three years after the first retail sale of the computer," Apple said.

Some iMac owners can't seem to catch a break. Prior to the GPU replacement program, Apple offered to replace faulty 1TB Seagate hard drives used in 21.5-inch and 27-inch iMac systems sold between October 2009 and July 2011.

Can't you just send the faulty part in on warranty and use the integrated GPU while you wait? Oh, wait. It's a Mac. Yep, that little black fruit on the front really makes it worth two weeks of downtime while you wait for your entire machine to come back!


Not sticking up for Apple at all.. (I loathe Mac)

But it is an all-in-one system..I'm sure Vizio and other companies that make AIO systems run into these p;roblems aswell..

The difference is? the windows variant of same parts slapped together and sold with a non-Apple name plate cost 2-3 times less... Hence the


I think that it's cool that they'll fix them. Must have been a lawsuit in the works. Ha-Ha!


Yeah, pretty much all AOI computers suck.


Just theorizing, but I can't help but wonder about this and read into it a little.

While AIO/laptops and cooling power-hungry chips can be problematic in certain designs, this issue sounds not unlike some well-known but not-often reported on issues on some amd gpu s[censored].

While I am unsure of Barts/Blackcomb, but certainly some early Pitcairn parts had issues because some cards had electrical noise problems (because of capacitors; base spec too low from amd?). Some AIBs had issues with their cards causing issues very similar, if not identical, to those mentioned in this article (ie the black screen issue). It has since been rectified as far as I know, but with the proximity/power envelope of Barts vs Pitcairn combined with the fact mobility 6970 uses a mxm module rather than the notebook standard of bga, I cannot help but wonder if there is some correlation. Seems possible, but it certainly could be something else as well.

Here is TPU article referencing the issue with Sapphire cards, but it's insinuated this is an issue beyond a single AIB because of amd's involvement and response:
