I was going through storage, found a package with a few RAM, the package was marked "Mac" but is from long enough ago that I don't remember what I bought it for. (I have had a lot of iMac's of all different years over the past 10 years).

I was suprised to see that there's no site (that I found) that can reverse search what RAM might fit. But I do know it was ordered for an iMac or at least Apple computer, and I'm hoping someone who knows RAM better than I do would recognize it.

Thanks in advance!

DDR3L SO-DIMM, aka "low power laptop RAM" that was the generation of RAM commonly used between 2012-2015.

Please note that this is generally *NOT* compatible with slightly-earlier "DDR3" RAM that is *NOT* low-power.

The systems this could work in:

MacBook Pro Mid-2012 - non Retina models. The only MBP to use DDR3L. The Retina models switched to soldered-not-upgradable RAM.

iMac Late 2012 to Late 2015 27" (The 21" moved to soldered RAM slightly earlier.)

The Mac mini and MacBook never used socketed DDR3L, moving directly from DDR3-not-L to soldered RAM. (or in the Mini's case, DDR3-soldered-DDR4, with no DDR3L socketed step.

Mac Pro used full size DIMMs, not the "half-size" laptop SO-DIMMs. MacBook Air always had soldered RAM.

.....iMac Late 2012 to Late 2015 27" .......

THAT'S what it was for! Thanks so much. I have a few Late 2015 27" Retina iMac's, that must be what I bought it for. This helps so much, I don't know how someone would know all that, but I knew if they did, they'd be on here.

Thanks Anon Freak and everyone else... This so so fast and extremely handy.

My Mini 5,3 2011 is nonetheless happy using 16GB of DDR3L. No idea why, when most Macs are too fussy to do such thing! But it works, so...
Yeah, DDR3L is an odd beast - some systems that shouldn't support it do, and some that should don't. It doesn't help that the *chipset* often supported both, but the actual full system manufacturer only qualified it for one of the two, or had a firmware lock or something.

Can be used in iMac late 2009 to iMac 2015, I guess. I have some of those in my iMac 2009 27".
iMac 2017 and later use DDR4.
