Memory Upgrade

[cthomas1489]

Hey all,

So I'm buying my first mac come the iMac refresh next week. I'm going for the 27" but buying it with stock RAM so I can upgrade it myself. I am currently selling my custom built PC piece by piece and when I was taking out the RAM it hit me that this may be compatible in the iMac (I've never upgraded / even owned a mac so not sure, wanted to double check).

According to this (which is for the current generation)

It sounds like the RAM i have would work. This is the RAM

Also, this is probably an easy question to look up but while I'm here I thought I'd ask. How many dimm slots are there in an iMac. I know it shows max memory to be 16GB so I was thinking 4 but I don't know. Also are memory specs / dimm slots looking to change with the new refresh? ie. 1666MHz , 32GB max, etc...

Thanks guys!

iMacs use laptop RAM (i.e. SODIMMs) so the RAM you have is not compatible. iMacs have four RAM slots and unofficially support up to 32GB of 1333MHz DDR3. Next gen will likely support 32GB as well (though might be only 16GB officially) and at least speeds of 1600MHz (though Apple may use 1333MHz).

The RAM won't even fit. It's desktop RAM, while the iMac uses notebook RAM (SODIMM, which is smaller)

The iMac has indeed 4 memory slots

The upcoming iMac will probably also have 4 slots for SODIMM memory.
Why? Well because the design is probably going to be the same -> the exterior won't change -> the size of the memory upgrade door won't change -> SODIMMS are the way to go.
PC3-12800 (1600mhz) memory could be coming, however I doubt Apple will use it...

Yep, rereading that first link I see that. Oops!

Thanks
