We’ve received four configurations of the 21.5″ and four configurations of the 27″ machines so far.  The quad core i5 and i7 machines aren’t due out till later this month.  Between the advancements in Snow Leopard and adding additional memory to these computers, they sure can go fast!

In fact – we found up to a 46% performance boost by installing the OWC 16GB Memory Upgrade Kit versus the factory installed 4GB.

We’ve run the machines through a rigorous battery of benchmark tests to test not only the pure processing speed of these machines, but also show what adding OWC memory to the setup can do.  Additionally, the different video card options have also been pitted against each other, so if you haven’t purchased your iMac yet, we now offer a definitive tool for making an informed decision on which graphics card to order.  Both of the Radeon HD options prove to generate twice the gaming frame rates than the Nvidia equipped model.  Not too shabby!

Unlike the prior generation of iMacs, these models have a total of four DDR3 memory slots. You can add an additional 4GB kit and have 8GB total or an 8GB kit and have 12GB total without removing  the standard factory 4GB.

Should you want to max the memory up to 16GB, you will need to take out those original modules. While Apple officially supports up to 16GB in all the new iMac models, they only offer up to 8GB in the 21.5″ model. Not only does OWC offer you the options for up to 16GB total, but even if you just need an additional 4GB, we’ll save you 50% compared to the same installed by Apple.

The results make our company mantra ring true.  ”More Memory = Faster Mac!”

As additional machines are run through the same tests, they will appear on the same page as our overall goal is to have every Snow Leopard compatible machine tested using the same process.

I really couldn’t wait on this… this news is just too juicy to bottle up for the whole weekend.

While we’re not completely finished with our compatibility testing, early signs are pointing to 8GB of memory supported in not only the new October 2009 Mac mini models, but prior generation mini models as well.  We believe we found the “secret ingredient” that makes exceeding Apple’s recommended 4GB maximum in these machines possible.

Previous testing revealed prior generations of the Mac mini were able to boot with 8GB of memory, but sadly either did not utilize the extra memory installed or – even worse – made the entire machine slower when accessing more than 4GB of memory at a time.  In Late August, Apple released Mac mini EFI Firmware Update 1.2 and this allowed these generations to boot without kernel panic. However, we still found that most systems slowed to a crawl when exceeding 4GB of memory in the system.

So far, here’s what we recently found though: our OWC 8GB Upgrade Kit works in the latest Mac mini 2.26 and 2.53 machines and are consistently and completely utilized by the machines.  We then tested these same modules on the prior generation Mac mini (early 2009)… and found them to work consistently as well! All units tested were running Snow Leopard.

We do have more testing to do using the same memory modules with prior Mac mini generation models running OS X 10.5. We also need to do performance tests to make sure that the additional memory actually gives a solid performance boost when more than 4GB is installed. But at this point, we’re feeling pretty confident that our “secret ingredient”…namely the quality of OWC brand memory… delivers the reliability you desire.

Be sure to check back Monday as we’re hoping to complete our testing at that time and be able to confirm that we will support over 4GB of memory in the Mac mini, or if my excitement got the better of me.

Snow Leopard is coming and with it will be a major streamlining of the whole code base. This is a bit of a mixed blessing.

This streamlining (and the addition of a number of new technologies) will allow for a reduction in size of an OS installation, while still allowing for a decent jump in speed and/or efficiency.

The down side of this, though, is that Snow Leopard will only run on Intel-based Macs. This really isn’t something unexpected. Every iteration of Mac OS and OS X has had some sort of hardware cutoff, and this time around it’s “Intel processors only.”

This is understandable; by limiting to one type of processor, the redundant code can be eliminated, allowing for more efficient use of system resources and overall optimization. The OS is able to move forward by leaving behind that which holds it back.

However, this is also a bit of an annoyance to those who have PPC-based machines, many of which are still in operation. The new OS doesn’t support it, and as a result, many day-to-day applications may soon no longer work. That doesn’t mean they’re not useful, though. Heck, I still challenge any other Mac to beat my Mirror Drive Door in consistency and performance when benchmarking FireWire 800 hard drives.

While the newer versions of some software may eventually require Snow Leopard, anything currently shipping will work just fine under Leopard. There should be a number of Security Updates for 10.5, just as there were for 10.4, so you’re not being left high and dry in that regard. Finally, many third-party apps are coded so they’ll work just fine under any OS X version from 10.3 and up.

If, however, you require the latest and greatest in OS and applications, then you’ll be needing an Intel Mac soon. That, however, leaves you with the question of what to do with your PPC Mac.

Even though they may not be suited for your Snow-Leopard-Requiring day-to-day tasks, PPC machines are still capable of acting as single-task workhorses. Here’s just a couple of ideas:

File Server: OS X’s built-in file sharing allows for easy setup of a machine as a simple file server. For those with more advanced needs, OSX Server has a number of extras that should easily do the trick. All you need is an 867MHz G4 processor or faster. Those with G4 Towers that don’t quite make this speed requirement can still use Leopard by first installing a processor upgrade. You can then install up to 4 or 5 extra internal hard drives, either on the internal ATA bus, or add a SATA card and put in the largest, fastest drives you can. A couple of quick licks in the Sharing preferences, and your files are available anywhere on the network you want them to be. While you’re at it, you can also set up Printer Sharing on that machine, allowing all your networked computers to share the same printer, too.

Kids computer - Got kids that have homework to look up or games they want to play? While it may not play the latest and greatest games, your PPC Mac has enough life in it to cover many kids uses. A decent word processor for reports, basic email & Web apps and some older games all run well on these machines. Once you have what your kids need installed, simply set up their account(s) as needed, and then fire up the Parental Controls preference pane. There, you can limit time spent on the computer, bedtime, which sites can or can’t be visited, and the like. You can even limit which programs can be run.  Once it is set up, your kids have a terminal of their own, leaving your machine open for your own marathon sessions of World of Warcraft.

Guest Terminal - Many years ago, I was renting a house with three other people, and we all were frequently online. The main problem was that only three out of the four of us owned computers. The fourth would always need to “borrow” one of ours. Unfortunately, they also had a habit of downloading whatever caught their fancy, opening up possibilities to viruses or, at the very least, filling up the hard drive. As a Mac user, I had more resistance to viruses than my Windows-using roommates, so I set up a “spare” machine (in fact, my trusty Wallstreet PowerBook) with a “Guest” account, where they could check their Web-based email, read news, etc, but they couldn’t change anything or save any files. It worked great. An older ‘Book can easily be left in the guest room with a similar setup, allowing overnight guests a way to check their email while visiting without exposing you to their careless computing.

Music Repository/Jukebox - If your music collection is approaching the proportions of some of the people around the office here (myself included), it may be time to move a good portion of it to a central location, especially if you have multiple machines you listen to it on. Several years ago, I wrote a piece on turning a G3 iMac into a simple jukebox. Once you’ve set your computer up with all your music, simply turn on the option to share the library in the preferences, and you’ll be able to listen to music from that library on any computer running iTunes on your local network.

Dedicated BitTorrent Client - Though most people immediatly think “illegal file sharing” when they hear “BitTorrent,” it is also a very effective way to distribute large files legally. Examples of this include independent bands with MP3s that don’t have the server bandwidth and various distributions of Ubuntu Linux. By dedicating a single machine to this task, it frees up other machines (and their bandwidth) for more immediate use. I know several people who use a G3 iMac for this purpose.

Curing diseases - Truth be told, this could be added to any of the above suggestions, but I’ll put it down as a separate item anyway. Even if you’re not using your PPC Mac all the time, there’s no reason it can’t be working. Set up Folding@Home, and put those spare processor cycles to good use, folding proteins and helping to find cures to diseases.

There are many more dedicated uses out there – the possibilities are really only limited by your creativity.

Of course, to get the most out of these machines, you’re going to want to make sure they’re running at peak performance. Maxing out the memory gives you the most bang for your buck, but adding a faster hard drive and even upgrading the processor can add some significant “oomph” to your PPC’s performance to its new tasks.

Even if you don’t know what upgrades are appropriate for your machine, OWC’s got you covered there. Simply check out the easy-to-use “My OWC” upgrade finder, enter in your computer’s information, and you’ll be given a list of compatible upgrades.

Don’t worry about Snow Leopard leaving your PPC Mac behind. With a little creativity and OWC, your PPC Mac can get a new lease on life.

Just as we mentioned last week, we’re putting together a bunch of new instructional videos for upgrading the Macs released this month. They will be released over the coming weeks. This week, we’ve managed to pump out not one, but two instructional videos for you!

Head on over to our Tech Center or our YouTube channel and learn how to upgrade both the memory and the hard drive in that perennially upgrade-challenged Mac: the Mac mini. We must warn you: this upgrade is not for the faint-of-heart.

Don’t worry, though. If, after seeing the videos, you decide that you’d like to have the upgrade, but without the fuss of doing it yourself, we’ve got you covered there, too. Check out our upgrade service, where you can have these upgrades performed by our crack in-house technicians. You can think of them like personal trainers for your mini.

In the meantime, we’re going to keep cranking out the videos, so you can learn how to upgrade the rest of the updated Macs.

Frugality is en vogue in today’s world…but it’s something that I was taught growing up, so I’m always looking for added value in my own pursuits as well as for what OWC can offer to you. With that in mind, did you know that after purchasing high quality, high performance upgrades from us to make your Mac like new, you can send us your working Apple memory modules, hard drive and optical drive and we’ll send you cash back?
