The OWC Test Lab technicians have been at it again. After hearing a few forum whispers of 32GB of memory working in the Late 2009 iMacs, we started our own investigation into the matter.
To be honest, we weren’t very optimistic on this rumor as, by specification, the Intel processors used in these machines list a maximum of 16GB of total memory…and our initial OWC MaxRAM Memory Certification tests didn’t pass.
We started our testing with the base Core 2 Duo (iMac10,1) model and have indeed confirmed that the Core 2 Duo models max out at 16GB of memory. When more than 16GB of memory is installed in those systems, the machine just would not complete booting. The prospect wasn’t looking too good.
But then we tested the other end of the spectrum with the 2.8 GHz Core i7 (iMac11,1) model and that is when the testing started to tell a completely different story. Article Continues…
Other World Computing announced today the immediate availability of the OWC Memory Upgrade Kits from 8GB to 32GB for 2012 27″ iMac models that began shipping recently. OWC’s kits offer memory configurations not offered by the factory as well as savings up to over $400 compared to same size factory options. Like all OWC Memory Upgrade Kits, a ‘how-to’ install video and OWC Lifetime warranty are included.
One of Easiest to Upgrade Macs Ever Produced
Unlike the 2012 iMac’s complex install process which requires removing the screen with a custom upgrade kit developed and offered only by OWC, the 2012 27″ iMac has been hailed as one of the easiest to upgrade Macs ever produced. A memory access panel on the rear of the 27″ machine ejects via a simple push button located above the power input. Adding more memory is a simple, several minute process of installing new modules into the memory slots and reinstalling the access panel. Therefore, Mac performance experts recommend selecting the least amount of factory installed RAM when ordering a 2012 27″ iMac. Article Continues…
While the Apple Store is currently showing that the 27-inch iMac is available to ship in January, our first pre-ordered model arrived today. Here’s a few unboxing photos for your pleasure while we begin our compatibility testing.
As always, follow the OWC Blog for industry coverage, tips, and more tricks for keeping your Apple products at their best.
It is here at last! Our first Apple Thunderbolt Display (27-inch) we snapped a few photos for your unboxing enjoyment before we sent this along for testing.

You know that feeling of accomplishment when you’ve overcome a huge obstacle and you can’t wait to tell the entire world about it? Well, we’ve got it; we’ve overcome the whole “fan/drive sensor” problem found when installing a non-factory drive in the 2011 iMacs. That means we can now officially announce the OWC Turnkey Program for the 2011 iMacs.
We’re also going to one-up the 2010 program by including upgrade options for both the 21.5″ and the 27″ 2011 iMac models.
That drive sensor thing was a big hurdle. Apple uses a custom firmware that sends temperature info in a non-standard fashion. Unfortunately, unless the drive has this special firmware, the fans spin at full speed. We wanted a solution that would be a long-term solution that wasn’t dependent on a software patch or hack. Though those sorts of fixes can be temporarily effective, we didn’t want to rely on them for two reasons:
- they put overhead on the bus which can reduce performance
- a software solution can can fail or be rendered non-functional by a wide variety of actions (software updates, system reinstalls, etc.) which could risk the hard drive and the data contained on it.
So, we went another route and developed a hardware solution that interfaces accurately and properly with what can be viewed as a frustratingly unique temperature data monitoring method by Apple. While our solution adds a little bit to the cost of upgrading the iMac’s hard drives, we feel that cost is more than offset by the advantages it has over software solutions. Article Continues…
