Hi guys.
I have an iMac 27" late 2012, 3,2 GHz Intel Core, RAM 16 GB DDR3 1600 MHz, NVIDIA GeForce GTX 675MX 1024 MB, model number A1419, EMC 2546.
Now I would like add 8 GB of RAM (4+4+8+8) but in the Apple Reseller says that isn't possible... 32 GB or nothing.
Also I ask to add an extra disk SSD (now there the classic HDD 1TB), but says that isn't possible... only Fusion Drive od SSD 1TB.
I'm confuse...
iMac, OS X El Capitan (10.11.3)
You now have two 8 GB modules in the upper two slots. The lower two slots are empty and you want to add two 4 GB modules. You may do that. The reseller is wrong. However, RAM cost is pretty cheap, and you are looking at adding to 24 GBs or 32 GBs. How much more will two 8 GB modules be over two new 4 GB modules? Just be sure you have the correct specs:
| Maximum Memory | 32 GB |
|---|---|
| Memory Slots | 4 - 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM |
Kappy is correct, the reseller is wrong. A 2012 27" iMac may accommodate 8, 12, 16, 24 or 32GB of RAM. The critical thing to remember is that RAM should be added in matched pairs and that the RAM has the correct specifications of 4 - 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM.
Thanks Kappy!Now I have 4 modules 4GB, totale 16 GB. I would like replace two 4 GB modules with two modules 8 GB.
In Italy, in Apple Store, two 4 GB modules is 100 Euro, but 8 modules 8GB is 230 Euro.
Ok... if I spend 230 Euro I have 32 GB RAM but is expensive!
The memory specs is correct: 4 slot 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM
Hi rkaufmann87, thanks.
Now I'm confused... the tech specs that I read here iMac (27-inch, Late 2012) - Technical Specifications says:
Memory
8GB (two 4GB) of 1600MHz DDR3 memory; four user-accessible SO-DIMM slots
Configurable to 16GB or 32GB
I' don't understand...
***Slight warning***
I have the same model iMac. I had a very hard time removing the RAM door as it is a tad difficult to get to as well as installing the RAM. You needed the strength of Arnold Schwarzenegger to install the RAM. The repair tech ended up coming to my house (I have AppleCare) to install & even he had a very hard time seating the RAM.
What he ended up doing was placing the iMac face down (screen down) on the table. Had trouble removing the RAM door as I did. He had to use his whole body strength to get the RAM into the slots. He also used the rubber handle of my hammer to slightly tap the ends of the RAM into the slots. Once you hear the "click," the RAM is seated correctly.
Add Ram to iMac 27 late 2012
