Macintosh RAM Configurations for Power Macintosh Computers. We DO NOT GUARANTEEthese listings are complete or accurate. Check other Web sources including Apple

"Applecare Knowledge Base archives" for complete information. Corrections would

be appreciated.

Macs prior to the PowerMac use either 30-pin SIMMS or 72-pin SIMMS (2K refresh), with

one exception: the Mac IIfx uses 64-pin SIMMS. The Mac 128K and 512K do

not accept additional memory. Multiple entries for a model means it may

accept various kinds of memory. Definitions of these terms are available via a Web


Power Mac 4400, 7220 168-pin DIMM 3.3 V unbuffered EDO

Power Mac 5200/75 LC, 5260/100 72-pin SIMM 2K refresh

Performa 5200, 5210, 5215, 5220 72-pin SIMM 2K refresh

Performa 5260, 5300, 5300/100LC 72-pin SIMM 2K refresh

Power Mac 5400 Performa 6400, 6360 168-pin buffered EDO or FPM DIMM 5V

Power Mac 5400 Performa 6400 168-pin buffered EDO DIMM 5V

Power Mac 5500, 6500 168-pin DIMM 5V EDO

Performa 6200, 6205, 6214, 6216, 6218, 6220, 6230, 6290, 6300, 6480 72-pin SIMM 2K refresh

Power Mac 6100, Performa 6110, 6112, 6115, 6116, 6117, 6118 72-pin SIMM 4K refresh

Power Mac 7100 72-pin SIMM 4K refresh

Power Mac 7200 168-pin 5V DIMM **

Power Mac 7500 Series 168-pin 5V DIMM

Power Mac 7300, 7600 Series 168-pin 5V DIMM

Power Mac 8100 72-pin SIMM2 4K refresh

Power Mac 8500, 8600 Series 168-pin 5V DIMM

Power Mac 9500, 9600 Series 168-pin 5V DIMM

G3, G4 Macs: not listed here yet.

The Power Mac 7300, 7500, 7600, 8500, 8600, 9500, and 9600

series computers have a memory interleaving feature. Install identical pairs

of DIMMS in same-numbered slots to improve performance.

**Note: for PowerMac 7200's, EDO DIMM memory MAY DAMAGE THE MOTHERBOARD! according

to Apple. For the other DIMM models EDO memory will function but not as EDO memory. Check

Apple's document "Power Macintosh: Using FPM, EDO, SDRAM, and SGRAM", Apple

Article ID: 19456, for details.

The PowerMac 6100 will accept 64MB* 72 pin SIMMS. Other Macs which accept

72 pin SIMMS will only see 16MB of a 64MB SIMM.

This document last updated: Aug 1 2002
* Various sources have reported success with 128MB SIMMs: search for further information before purchasing.

An excellent page on compatibility of G4 CPU modules between different models.

From theos911's post here.


Subject: G4 processor swaps

You can use Sawtooth/Gigabit Ethernet CPUs in a Digital Audio without any changes at all. Apple System Profiler may say it is running slow but other programs can generally detect it properly. (I have personally tested this, including changing the resistors and running benches) The only issue is that you are running a really slow CPU and the bus gets dropped down to 100MHz but it is good for testing a suspect motherboard or CPU.I have not tried in a QS, but the QS is similar enough to the DA that it *should* probably work. ymmv

Finally got some high resolution photos here:

Best I can do with the scanner I have on hand. Friend of mine has a really nice, really expensive DSLR that I'm sure would do a better job. This sucker is for sale if anyone is interested; still untested but I'd accept a return+refund if it didn't work.


Need link to the old Ports & Pinouts(?) document that shows the @$$end of Macs up to the day the document was created.

edit: I found it on the QS'02, the filename is mac_ports_pinouts.pdf for my copy, coul

Didn't find a link, so I may have changed the name. It's a VERY useful Apple Document.

This seems like as good a place to leave this as any, at least till we have a functioning wiki again.
