I've read that the MBP mid 2010 with core duo will take 16gigs but other sauces say 8gigs.

Can anyone clarify?
 
"The "Mid-2009" and "Mid-2010" MacBook Pro models support 1066 MHz PC3-8500 DDR3 SO-DIMMs and officially and unofficially support a maximum of 8 GB of RAM with one odd exception.

"Specifically, as discovered by OWC, the 13-Inch "Mid-2010" MacBook Pro models (and only the 13-Inch models) -- the MacBook Pro "Core 2 Duo" 2.4 13" Mid-2010 and "Core 2 Duo" 2.66 13" Mid-2010 identified by MacBookPro7,1 -- can support up to 16 GB of RAM with dual 8 GB memory modules if they are running OS X 10.7.5 or higher, have been updated to use the latest EFI, and are equipped with proper specification memory modules."

I can confirm all of the above but did not understand the part regarding EFI?

Fantastic - currently trying this. I'll keep you posted. Thank you.

If you're sure you used the right RAM and met the other conditions, and it matters to you, it might be worth contacting Every Mac and/or OWC, as they're generally reliable sources.

I've tried to attach an image of the ram here.

Looks good to me. Try one stick at a time. It's not unusual to get a bad stick. (I don't recall if it matters which slot you put one stick in, but it might.) OWC is still selling this RAM (their own brand of course) for your machine, so they still think it works.

2010 15" MBP - 8GB Max
2010 13" MBP - 16GB Max

Weird... but true.

I'm struggling to get 16 gb to work on my 13 inch. Could be a couple of bad modules but I'm going to go with 8gb of Crucial RAM.

It is. Maybe I got some faulty modules? I also updated before fitting them.

Sounds like the case. Also, remember you want 16GB of the slowest memory you can find, as the newest fastest modules may not clock down well as these are PC3-8500 or PC3-10600.

They use different chipsets, not so weird really.

Weird in the sense that the 13" (considered lower power) had a higher capability than the 15" flagship.

Yea, it's weird than the Penryn C2D could do 16GB when the Arrandale i5/i7 was newer. But 8GB was still a lot of RAM back then, you had to go with Clarksfield if you wanted 16GB (4x4GB). I'm sure there's a good reason it was that way. And, in 2011 when Apple updated the MacBook Pro 15" you could have 16GB

These are the ones I got: http://imgur.com/a/Km5Ah

Since swapped them for 2 x 4 gig Crucial
 
I upgraded my Mid 2010 13" MacBook Pro from 4GB of RAM to 8GB of RAM years ago. But now I want 16GB of RAM and am having a hard time finding compatible RAM.

I could not find any that worked for me
 
Dont forget at least on the 15" 2010 MBP, you can get a new EFI firmware update thanks to Sierra 10.12.4.

Either update to 12.4 or do a full install of the 10.12.4 and it will install a hidden firmware update thats not available separately on the Apple site.

The Sierra 10.12.4 update or full installer has hidden EFI updates for MANY macs that can run Sierra.

What does the EFI update affect? It probably doesn't let the 2010 upgrade to 16GB RAM, right?
 
Interesting question, as far as I know, its just a security update, but Apple never published information about this batch of 12.4 EFI updates. Would be cool if it allowed 16GB, I'll have to test that out.
