Q: Macbook unibody (mid 2010) max RAM support

as i have read in few resolved questions of discussion forum its stated that with the EFI update RAM support can be extended more than stated by APPLE...

 

i have installed latest EFI update MB71.0039.B0E (EFI 2.1) on my macbook unibody mid 2010 (OS X YOSEMITE 10.10 updated) & it has 2gb ram (1gb each in slots) ...

 

its lagging way too much after os x update so i'm in need to update the RAM otherwise snow leopard was running like a knife in butter

 

-> so the question is can anyone tell me the maximum RAM support with this EFI & OS X update

MacBook, OS X Yosemite (10.10)

    RAM Type:PC3-8500 DDR3Min. RAM Speed:1066 MHz
    Details:Supports 1066 MHz PC3-8500 DDR3 SO-DIMMs. Also see: How do you upgrade the RAM in the White "Unibody" MacBook? How much RAM of what type does it support?
    Standard RAM:2 GBMaximum RAM:16 GB*
    Details:2 GB of RAM is installed as two 1 GB modules, no slots free.

     

    *Apple officially supports a maximum of 4 GB of RAM, but third-parties have determined that it actually supports 8 GB of RAM running Mac OS X 10.6 "Snow Leopard" and 16 GB of RAM running OS X 10.7.5 "Lion" or higher and the latest EFI update.

    BBuy ram from either Crucial or OWC, avoid others.

    Yes, you're using Yosemite. The OS is designed to use as much of your ram as it can in order to speed everything up, as you open other applications and they call for ram Yosemite releases it to them, it's genius really. You don't want your ram sitting around doing nothing, you want it working for you constantly. Activity Monitor has changed the way it reports usage now too, you want to watch memory pressure How to use Activity Monitor - Apple Support

    Don't be tempted to use third party apps to monitor, clean or free up ram.
