Unofficial 16GB ram on Mid2010 MBP? True?

[MacMike81]

Officially Apple claims a 8GB max ram. Apparently OWC found that if it is a certain model it will unofficially support 16GB.

Sounds like it has to be a "certain type" of ram. Not sure if that is OWC jargon for "their product"?

Might run to local PC store today and check it out. How do these compare?



Apples official specs -

Double Data Rate Small Outline Dual Inline Memory Module (DDR3) format
- 67.6mm x 30mm (1.18 inch)
- 2 GB or 4 GB
- 204-pin
- PC3-12800 DDR3 1600 MHz type RAM

16GB will work in the 13", but not in the 15" of the 2010 model

I’ve got 16gb installed in my early 2011 13”

I bought the 16GB Crutial kit. I installed it and no boot. black screen but led "heartbeat" was steady on.

I swap memory modules around and swap one out with the old 4gb. Finally got it to boot with 12gb.

Not sure why it won't see 16?

If you have a 13-inch 2010, it SHOULD see 16GB.
If one 8GB stick works, try a different 8GB stick (Tell Crucial that you have one bad stick, they will replace it for you)
If you can't get the full 16GB Crucial to work, send it back - purchase the OWC RAM.
