I want to build a few Skylake boxes with 48GB of ram, maybe 64GB. Yes, I can do this with an LGA2011 platform, but it's less performance for +$200 cost. Where in the world are the 16gb unbuffered DDR4 memory modules? Newegg has a few 32gb (2x16gb) kits listed, but they are all out of stock. I could not find any at Amazon. Are these being snapped up by OEMs?
