Power Mac G5 Memory

While both the PowerBook and mini could use more memory, the Power Mac G5 is designed for memory upgrades. With most models having a full 8 DIMM slots, expansion is not only permitted, but encouraged by the design. You have to install DIMMs in pairs, so all DIMMs that were submitted were done as such. Keep in mind that most of these dual channel upgrade kits are advertised as the total memory size, not individual module size. So, if a module is labeled as a part of a 1GB package, it's most likely only a 512MB stick.

Once again, warranties and performance are identical between all contenders, so the comparison boils down to price. Apple offers aftermarket upgrades for the G5 through their store; however, their prices are extremely inflated, so we're here to present the alternatives.

Power Mac G5 Memory 2 x 512MB DDR400 2 x 1GB DDR400
Apple Upgrade $300 $800
Corsair $332 N/A
Crucial $278 $401
Kingston $224 $683
Mushkin $178 $382
OCZ $222 $511
PDP $168 $403
Transcend $219 N/A

PDP actually offered the best price at $168 for a 1GB upgrade, but finding the DIMMs may take a little bit of work. We had relatively good success with our online shopping partner, shopping.com.

For the 2GB upgrade, prices varied quite a bit ranging from as little as $382 to as much as $683 (not counting Apple's $800 upgrade). Mushkin takes the win at $382 for the 2GB upgrade.

Corsair

Corsair TWINX CMX512-3200C2PT (2 x 512MB)

Like OCZ, Corsair also uses a heatspreader on their Mac DIMMs, which makes them a tighter fit in systems like the iMac G5. Corsair's heatspreader is thinner than OCZ's, so it's not as much of a problem. The DIMMs will fit - it'll just be snug.

Crucial

Crucial CT322476 (2 x 512MB) / Crucial CT357475 (2 x 1GB)

Kingston

Kingston KTA-G5400/1G (2 x 512MB) / Kingston KTA-G5400/2G (2 x 1GB)

Mushkin

Mushkin 1GB PC3200 Dual Pack (2 x 512MB) / Mushkin 2GB PC3200 Dual Pack (2 x 1GB)

OCZ

OCZ PC3200 1GB Dual Channel (2 x 1GB)

PDP

PDP PSA1GG5K (2 x 512MB) / PDP PSA2GG5K (2 x 1GB)

Transcend

TS512MAPG5400K (2 x 512MB) / TS1GAPG5400K (2 x 1GB)

    It's nice knowing that there are cheaper alternatives; if all he had posted was "PC ram of this timing works" then we wouldn't know where to look for better prices.

    I really applaud the on-going interest in the Mac platform. It's nice to see a well designed, robust platform like the Mac/OS X getting some more attention.

    I don't get the article though. Couldn't it be summed up with the statement that 'Macs use standard memory but Apple apparently sets the timing in firmware'? 4 pages of how Macs use standard memory?

    I'll try to be better than the average complainer on the boards though. How bout an article about real problems associated with upgrading Macs. Perhaps something about upgrading optical drives and getting the mac to boot from CD? That is, you'd have to cover finding drives with compatible firmware or hacking compatability.
    Alternately, maybe go into the possiblilty of flashing various video cards. That'd be interesting. Running RAID on mac boot volumes? Which interface is best for Mac RAID [SCSI, FW400, FW800] since FW800 had issues on the G5s? Or, how bout tackling the possiblility that the software shortage is a myth? Pick several tasks and see if you can find the appropriate software to get the job done on the Mac.. that'd be interesting. It'd be nice to see someone do a well written overview of how to overclock and modify various Macs too.

    Cheers,

    So here's my experience:

    Got 2 Mac Mini 1.25's, and didn't want to pay $100 for 256mb more RAM. So I got some Kingston Value-RAM, DDR 400, for about $68 and popped the lid on the mini's. Worked like a charm. Both machines booted right up, and I had 2 extra 256mb sticks for my G4.

    I don't recommend just grabbing some RAM off the floor and throwing it in, but considering I've done this one, it's a good deal for anyone looking for RAM upgrades. I've also stuck Value-RAM DDR 400 in a Dual 1.25ghz G4, no problem.

    Lets look outside manufacturers that over price RAM for Macs. It's usually the same stuff as their cheaper counterparts, just a bigger price tag.

    For Crucial memory, do you have to get the upgrade they recommend? For me, they say to get:

    iBook (G4 1GHz), Part CT372708, 512MB, $146.27
    DDR PC2100 • CL=2.5 • UNBUFFERED • NON-ECC • DDR266 • 2.5V •

    But, I also noticed this memory, which looks similar:

    PowerBook G4 1GHz (12-inch Display), Part CT327971, 512MB, $93.99
    DDR PC2100 • CL=2.5 • UNBUFFERED • NON-ECC • DDR266 • 2.5V • 64Meg x 64

    Does the 64Meg x 64 mean it won't work in an iBook? I would rather not spend the extra $53 if they will both do the same thing.

    #6, that's indeed true, though I will say from my experience that Apple is the worst price-gouger on RAM. Dell would rank second. Crucial is a lot cheaper, and they're high compared to quite a few vendors.

    #7, if you were truly sorry for sounding harsh, you wouldn't post what you did. I find Anand's Mac information to be incredibly useful, as someone who does both PC and Mac. I urge Anandtech to keep doing the occasional Mac article, everyone moaning about it seems to say "Anandtech's becoming a Mac site" when it's easy to see the site is still heavily balanced (and rightly so) towards the PC side. Lots of PC users have become interested in the Mac mini, and I believe there is plenty of relevance.
  • michael2k - Tuesday, March 1, 2005 - link

    And who are you to say what the majority of Anand's viewers are?

    He does his thing for his pleasure as well as for the benefit of others. I'm sure HE was curious how the various ram vendors stacked up in his three Macs, and thought such research would benefit his readers.

    Or do you complain when he reviews SLI, or RAID, or high end gaming chassises because they aren't applicable to you? If it bugs you, don't read the Mac articles and let those who do care read them!

    Expanding your coverage is the only way to expand your readership; attracting NEW viewers and new visitors, rather than the existing one. Otherwise if he kept sticking to 'old formula', he'd get overshadowed by newer sites that DID do things better/different. So let off on Anand. I understand you might be unhappy, but how do you think all the old school Macheads feel about the new OS X and the new iPods that Steve Jobs has unleashed?

    Wow, another memory review that won't be relevant to the majority of your users. It's as bad as reading all of the extremely expensive memory reviews. I think alot of your readers would still like to see the value memory (PC) round-up that was promised about 6 months ago. And, if you insist on reviewing Apple products from here on out, maybe you should do it on anandmac.com or something like that with a link on the anandtech homepage.

    Sorry for sounding so harsh.

    Apple isn't the only computer manufacture that is guilty of exessive memory pricing. Dell's memory prices when upgrading there Laptops and Desktops is simply outrageous. My opinion is that if you buy a laptop or Desktop from any vendor is that you should buy it with the absolute minimum amount of memory that they offer for the system then purchase you memory upgrade aftermarket from Newegg or Zipzoomfly (or your favorite supplier).
  • paulsiu - Tuesday, March 1, 2005 - link

    Other than the SPD, how different is the Mac memory from the PC memory? I probably can't reuse PC memory in a Mac, but can I use the Mac Memory on a PC?
  • Chuckles - Tuesday, March 1, 2005 - link

    Then why do people buy 2-2-2 RAM for thier Mac's?
