iMAC 3.4ghz 27 inch memory - 1.5v vs. 1.3v

Thanks for the information regarding Cricial compatible RAM.

A rep from Apple care told me that he did not know the answer but he said that Apple trains him on what is important and if he did not hear anything about the voltage than he said it would be safe coming from crucial. The link you shared with me is great RAM. Furthermore, the newer 1.35v RAM (not 1.3v as I originally thought) is the newest RAM from Crucial that their memory advisor says is compatible with my iMAC. Of course they also say the one you shared with me is also compatible. I learned today that the difference has to do with heat and the 1.35v has less of it. I searched for 1.3v RAM and I came across some web sites talking about how the i7 chip can support both 1.5 and 1.35v. I am not planning on mixing both the OEM RAM I get stock and the RAM from Crucial. No, I plan on sticking 4x4gb RAM of the 1.35v from Crucial.com for some serious memory power to surf the web. Just kidding....I am planning on using Photoshop and running some programs in Parallels with Windows 7 Ultimate. One program I use called Pro Show Producer (slide show software) just has not come out with a MAC version yet. Oh, and I also have a Windows version of Quickbooks from 2009 that I will be using in Windows also.

Apple reps said that its not as much as the voltage as it is the other specs. Today I learned that it's safe either way. Thanks for chiming in.

Hello baltwo. I also saw those threads and thought...oh dang...what now. One of the guys said his left speaker started making a slight poping noise with his 1.5v RAM from Crucial with 16GB. He said that he tried 16GB of 1.35v RAM from Criucial and it was woking just fine after that. Apparantely good RAM specs are what this machine is going to want. I'll try 16GB of Crucial 1.35v RAM and go from there. I should be fine........

I also don't do heavy video editing. I mainly wanted the added RAM to be able to allot 8GB of RAM to both MAC OS X and Windows 7 when I have them running in my VM using Parallels. The slide show software I have would benefit from more RAM. There will also be some gains when I do some batch processing in Photoshop and want to burn a DVD and send an email at the same time. I've been running MAC and Windows software in VM using Parallels in my MBP with 8GB of RAM and its awesome when I need to use the Windows programs.
