When it comes to memory upgrades, Apple's CTO offerings for its
Mac
systems are options I recommend people avoid, not because of any
quality issues, but because of the ludicrously high prices Apple charges
for the upgrades. For instance, Apple ships its iMac systems with a
standard 4GB RAM, but if you want the optional 8GB or 16GB RAM upgrades,
you will pay $200 or $600, respectively.
These prices are more than four times the cost of most other
similarly sized and specced RAM upgrade options, which are just as
compatible with your iMac as Apple's RAM. While some might assume
Apple's memory upgrades are somehow special because of the price, the
truth is the memory is no different than that supplied by any other
manufacturer, and provided the specifications are the same, a cheaper
third-party RAM module should work just fine in your system, and save
you an immense amount of cash.
For instance, in looking at the $200 Apple charges for an 8GB upgrade
to its iMac systems, you can purchase a similar and compatible 8GB
upgrade of Mushkin memory from NewEgg for $45.
If you don't like Mushkin, then you can find similar specced RAM from
other manufacturers for a similar price. The difference gets even more
drastic with the 16GB upgrade, which from Apple will cost you a whopping
$600, but if you use a third party, the RAM upgrade will cost you around $100.
Not only does Apple charge a premium for RAM (far more than it does
for other CTO components like hard drives and GPU options), but it also
does not offer all RAM options its systems are capable of. In its
MacBook Pro lineup Apple offers a maximum of 8GB RAM, even though the systems can take up to 16GB.
Likewise, Apple's iMac systems are also advertised and sold short of
their true RAM capabilities. Starting in mid-2010, Apple's iMac systems
support up to 32GB of RAM, even though Apple claims the systems can only
be upgraded to half that amount.
It is unclear why Apple claims these lower capabilities of its
systems. Perhaps it is simply a matter of testing done on Apple's part,
but if you have one of the newer iMac systems (starting in mid-2010),
then even though Apple claims you can only put up to 16GB in the
systems, you can install 32GB if you wish to maximize the capability of
your new system, and do so relatively cheaply.
Recently, Mac upgrade manufacturer and peripheral distributor Other World Computing released a new 32GB RAM upgrade module for iMac systems,
which should be compatible with mid-2010 or later iMac systems. The
upgrade is priced at $349, and as such is more than $250 less than the
price Apple charges for its 16GB upgrade.
OWC's RAM upgrade is a solid option for iMac users to consider, but
even it does not beat the available options out there. A quick search
shows that if desired, you can get a similar 32GB RAM upgrade from G.SKILL for $100 less than OWC's upgrade.
As with any servicing to a computer system, the idea of upgrading the
computer's memory may sound like a technical procedure; however, memory
upgrades on Mac systems are one of the few user-serviceable options for
which Apple provides detailed instructions.
Upgrades simply require you shut off the system, open a latch or remove
part of the case, and then swap out the old memory modules for the new
ones. Then close the case and start the system -- the process is easier
and less painful than even hard-drive upgrades.
The only extra step that I recommend everyone do following a RAM
upgrade is to thoroughly test it, which can be done using third-party
utilities like Rember, or with using Apple's built-in hardware tests.
