Specs for Firmware Dump Request

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?

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...
