07 08 imac probably uses DDR2. So no, you can't put the '12 MBP ram into your imac.

That's some August 2012 MBP you have there!!! Really??? ;)

Currently there is 4GB of RAM in my August 2012 MBP and 1GB of RAM in my other iMac (2007 or 2008).

I want to max out my MBP to the highest it can go. Could I put the 4GB from the MBP into the iMac to save money and get an upgrade out of both?

The 2007 or 2008 machine will use either 667 MHz or 800 MHz DDR2 RAM. If it is an Early 2009 machine it would use DDR3-1066. Keep in mind that these are Apple introduction dates, not your purchase date. It is entirely possible to have purchased an Early 2008 Mac in 2009 (and doubly so if you purchased from the Refurb store)

The current model Macs use DDR3-1333 RAM, so RAM from it would not be usable in any 2007-2008 DDR2 Mac. We have seen problems using DDR3-1333 RAM in DDR3-1066 Macs as well, so it is a YMMV situation whether you can reuse new RAM modules in an early DDR3 Mac. It depends whether the DDR3-1333 module is correctly programmed to have the SPD (Serial Presence Detect) settings of the 1066 spec as well as the 1333.

We always ask for the Mac identifier number when quoting RAM -- an iMac from 2007/Early 2008 could have 667 MHz or 800 MHz RAM modules.

Hate to spend the money to upgrade both - but I guess this time the family iMac has to come first. We can't even upgrade to Lion yet!

And you may not even want to go the Lion "upgrade' route, and you sure couldn't with just 1GB of RAM "in [your] other iMac (2007 or 2008)".

But 1GB of RAM is really minimal and 4GB RAM and Snow Leopard 10.6.8 makes a nice user experience, (I use a 24" and 4GB myself with that era iMac) or even go with 6 or 8GB if your iMac model supports it.

Check with everymac.com for complete supported specs for your specific model.

Hey it's been a long time since I posted here but I wanted to pass along something.
I was looking to buy my Ram for my late 2011 MBP and was going to buy from OWC or locally but I ended up searching around a came across Patriot Ram that was being sold by Memory Express in Calgary. I figured I would take a chance on buy this Ram because the price was so cheap. I did buy the Ram and did a 5 hour burn in and have been using the Ram for about 3 weeks doing production work with no issues.
Anyway it's a good thing to get great prices so I thought I would share.

Too bad you didn't follow the often posted advice here at ehmac and use canadaram, you could have saved yourself some money, and got guaranteed RAM for $128.00.

16GB (4x4GB) is not the same as 16GB (2x8GB).

The lowest price for 16GB (2x8GB) is about $150, from what I can find. Canada RAM quoted me $189 for that.

Ooopppps... my mistrake. And pretty it's hard to get four chips into a MBP's two slots, unlike the iMac's four slots I was probably thinking of.

Too bad they don't seem to have any North American dealers for their RAM for what I could see or find:

In July 2008, our products start manufactured in Taiwan and it was taken over by another memory brand to offer lower price memory module of prime quality.
In October 2010, Exceleram was introduced to the German market and got quite successful in the market.

In September 2011, the Exceleram's headquarters was moved for the best strategic position from Germany to Taipei, Taiwan. As here is the largest and most important manufacturing plant of memory chips and modules in the world. To stay in Taiwan can provide the best and the real-time service for our valued customers.

So who's really making their RAM? There are only about 8 or 9 RAM manufacturers in the world....
A 2010 press release (http://www.exc.com.tw/html/pressreleases.html) says they have a Canadian distributor - PCCyber.com, but that website is currently down, supposedly "under construction", but hey, ho...I wouldn't be holding my breath on that: PC Cyber customers wait for computers, refunds (http://www.ottawacitizen.com/Cyber+customers+wait+computers+refunds/5805966/story.html)

The info was on their URL under press release:

More info at that URL.

So, this is a Taiwanese company that had a head office (briefly) in Germany and then moved back to Taiwan...and somewhere in there got sold? Whatever - it appears to be smoke and mirrors at the moment, as they have no North American presence and in fact no presence at all in the English speaking world except for South Africa.

Much as I'd love to see 8GB RAM chips for $50.... ;)

Just bought a 16GB kit for $122 + HST from Newegg. Free shipping for a few days.

They must have just got such a kit in to be available 'cause it sure wasn't showing up at their site yesterday when I checked.

Nice upgrade buy BTW!! :)
