Best RAM for 2017 5K iMac

[XmasRights]

I'm going to buy a 2017 iMac pretty soon, and I'm looking to boost the ram myself. Is there a noticeable difference in the type of RAM you install?

I'm torn between:
Generic Crucial
http://amzn.eu/9c3DXan

Corsair Vengeance
http://amzn.eu/e8VcEip

Are there better alternatives out there?

Thanks All,
Chris

I'm personally partial to Crucial but you will find posts from users of both (as well as other brands) in the 2017 iMac in this comprehensive thread.

I purchased the Corsair from Amazon when I got my iMac last September. I paid $220 then and it is now at $360 (32GB). Haven't had any problems and it comes with a lifetime warranty, for whatever good that really ends up being.

I got OWC 2x8GB in the UK back in June 2017 from Macsales UK (1 x OWC DDR4 PC19200 2400MHz SODIMM - 16GB Kit (2 x 8GB) £176.05) It works fine. It’s now gone up c. 20% cost.

Didn't know about price hikes, but nothing I can really do about that. Looks like any compatible RAM is fine, so long as it's not a knock off from eBay. Will likely go for the Crucial RAM in that case, and save some cash.

If you’re adding it to existing RAM you want to pay attention to which sticks go in which slots, to do with dual channel configuration you want to keep matching pairs - there is another thread on that. Mine came with 2x4GB in alternate slots (1 and 3) and I added in between the 2x8GB new sticks (2 and 4). Works fine.
