All of the RAM manufacturers are already selling RAM for late 2015 iMacs except for Crucial.

After some digging it appears as if Crucial has two tiers of RAM: 'Generic' and 'Premium'

They already supply the 'Generic' RAM for late 2015 iMac, although its not officially listed on their site as late 2015 iMac RAM.

As someone who has no idea about RAM, but wants to buy some for my iMac, i'm just wondering if its worth waiting for the 'Premium' RAM which they say will be available in the next few weeks?

What will be the difference, if any, to RAM already available?.....One set i have my eye on are the Kingston Hyper-X. Should i buy these or wait?

The late iMac 5k has RAM clock at 1867Mhz. I don't know the premium vs generic will give you a big different? All I can tell is: if you plan to use Apple RAM comes with the iMac, be sure the to get the RAM that match the timing. I believe it is CL13. otherwise, the SIMM clock will drop. If you plan to replace all, then you don't need to worry about timing. Any 1866/7Mhz will work. How well it works vary from manufacture to manufacture. I have G.Skill and it is working great.

When I look at the Crucial UK site it shows generic RAM that meets the 1866/7, CL13, 14900, SODIMM etc specification but the site also indicates that it is not compatible with the I7 27inch Late 2015 Retina Mac. The specification doesn't appear to be any different to that of the Kingston Memory in Post 1 above. Is the Crucial premium/generic thing just clever marketing?

I bought 16gb (8x2) of the Kingston HyperX, the CL is 11. I bought it because I saw a few people recommend it.

I think Premium and Generic is their way of saying crappy and top quality. On the site they basically say that the premium RAM is rigorously tested and made from quality components, and the generic RAM is not.

I suppose it'll be more money when they do finally come out, but if they are not too expensive i think i'm going to go with Crucial unless someone can tell me its a waste of time and money waiting.

Hyper X look cool but i'm thinking Crucial are making a product specific to the late 2015 iMac?
