iMac RAM help needed

[mchong75]

Ok, need help from the techies.


I want to upgrade my iMac ram but I'm not sure if I'm max'd out based on my iMac's supported memory.

Here's my info. It's an older....2008 (i think) 24".

Can I at least upgrade to 8 GB of RAM?

Put your specs into Performance Upgrades; FireWire USB SATA Storage; Memory, more at OWC on the left where it says my mac and they will let you know everything you can upgrade.

Samevbut different site this is Crucial. Bought from them in the past. I believe some Intel Macs may have had firmware update, but not certain, to accept RAM higher than when first out.
Crucial link to iMac page: Apple Memory Mac Memory Upgrades for PowerBook PowerMac G4 G5 Mac Mini iBook iMac Memory

If that doesn't get you there just crucial.com and go to the iMac page.

A pearl; the memory modules can slip down and make bad contact. I had to put a piece of plastic foam under the modules then close.

I believe your iMac is tapped at 4GB, My father in law has the same set up......Well maybe not OWC says up to 6GB for the 08 or 8GB for 2009 model.

max memory is 6gb

4gb + 2gb

Thanks for the info everyone.

OWC site says 6 GB Max but Crucial site says 4 GB Max.......

If I can't get 8, I hope at least 6.

Even though I like to purchase a new iMac, I need to see if I can squeeze more juice out of this machine for another two or so years....

Crucial.com has a nifty web app that will diagnose your system and tell you exactly what ram you need and what its max is. thats how i ordered mine this past weekend.

Yes, you can put 2x4GB DDR3 memory in. I did that last year because 4GB just was not enough with photo finishing software (CNX2). I, too, have the 24" iMac. It is laptop memory, same as used in the PowerPC.


This is what I bought...

Amazon.com: Kingston ValueRAM 4GB 1066MHz PC3-8500 DDR3 SO-DIMM Notebook Memory (KVR1066D3S7/4G): Electronics

Are you sure? iMAC's came out with several different 24" models. What year is yours? Plus, doesn't DDR2 (Me) and DDR3 (You) variance make a difference?

I just ran the Crucial memory upgrade system for my model and it's telling me 2GB per slot.

Memory upgrades from Crucial.com - Determine My Memory Needs

Each memory slot can hold DDR2 PC2-6400 with a maximum of 2GB per slot.*

iMac Mid 2007 is Model 7.1 - 6 GB RAM
iMac April 2008 is Model 8.1 - 6 GB RAM (This is Your's)
iMac March 2009 is Model 9.1 - 8 GB RAM

To install the 6 GB you need a 4 GB in the left slot and a 2 GB in the right slot. Apple factory specification maximum 4.0GB, Other World Computing tested to support 6.0GB maximum RAM. All the information you need at this link:

Thank you.

I guess 6 GB is better than 4....

Time to shop now.
