Along with that, I've not reliably been able to find fast unbuffered ECC ram either. I've seen some 2333MHz stuff but not in 16GB DIMMs and nothing faster actually for sale (I've seen 2400MHz advertised but not actually available). I've got 128GB of 2133MHz and it works fine but it'd be nice to be able to get the extra performance considering how much it matters for the Zen core cpus

Samsung 8gb M378A1K43CB2-CTD and 16gb M378A2K43DB1-CTD I've only heard about these from buildzoid's overclocking video. https://www.reddit.com/r/overclocking/comments/exnrcz/buildzoid_samsung_8gb_ddr42666_cl19_ddie/ https://www.reddit.com/r/overclocking/comments/exnrcz/buildz...

  Those don't appear to be ECC capable unfortunately. https://memory.net/product/m378a2k43db1-ctd-samsung-1x-16gb-ddr4-2666-udimm-pc4-21300v-u-dual-rank-x8-module/ https://memory.net/product/m378a2k43db1-ctd-samsung-1x-16gb-...

Crucial has 16GB unbuffered ECC at 2666MHz native frequency, available within the last month. It's a very stable overclock at 3000MHz. I think I've got room to move up to 3200. I would love to get to 3600MHz, but that has seemed unstable when I've tried. CAS latency isn't the best, and tweaking this has resulted in a quite unstable system. I'm currently running 128GB of this: https://www.crucial.com/memory/ddr4/ct16g4wfd8266/ct16439854 https://www.crucial.com/memory/ddr4/ct16g4wfd8266/ct16439854

  Neat, that's definitely new and good to hear about. I'm eventually going to upgrade my 1950x and the rest of the system so getting to 3000 would make a huge difference already. I've managed to get my sticks to 2333 but they then report about 3 errors a week, and about 20 a day at 2666. The performance gains from that aren't enough to leave it like that and feel good about it to me.
