Reply: Specs for Firmware Dump Request

Got my RPi today and made 3 successful reads of my ROM for backup.
Flashrom is detecting my ROM chip to be:
Micron/Numonyx/ST flash chip "N25Q064--3E"

Now I need to find a stock Apple ROM dump that matches my hardware...

I've done a search for my Firmware in the EFI Firmware Dumps/Requests section of the forum.
I've found one that's similar to my MBP but not exactly the same.

Mine:
MacBook Pro Retina (mid-2012)
A1398 EMC 2512
Core i7 2.7Ghz
16GB RAM

Found in Forum:
MacBook Pro Retina
A1398 EMC 2512
Core i7 2.6Ghz
8GB RAM

Do the Processor speed and RAM size need to match for the firmware dump to work?
