I'm looking for the most reliable RAM for an iMac 27" 5k. I'm not married to the 8 gigs it comes with. Looking to add 32 gigs for a total of 40 OR simply replacing the 8 with 32. Whichever runs faster.
Any advice is much appreciated. I'm way down the rabbit hole and looking for a light at the end of the tunnel.

I'd go for Corsair but Adamanta is fine too. These days all have Life Waranty.
