I am not 100% but I assume that it would work if all the sticks are identical...you never really know these days however.

Hello Bogdan, One question for you: why you are using specifically Coreboot as boot-loader, instead of (AMI) BIOS? The question is because you are using desktop with AMD CPU for gaming. No specific needs for Coreboot, which is mainly for embedded applications. Any specific reason why you are using Coreboot instead of full fledged AMI BIOS? Thank you, Zoran On Sun, Apr 30, 2017 at 2:05 PM, BogDan Vatra <bogdan(a)kde.org> wrote: > Hi, > > I'd like to build desktop/workstation for my personal use (lots of > compilations + of course gaming on linux) > I bought 2 x 6276 CPUs and a KGPE-D16, eprom programmer, etc. now I'm > looking to buy some RAM. > My goal is to have a quad channel 64Gb and because I looking for a > desktop/workstation I think the best choice will be ECC UDIMMs and not > RDIMMs. > Will coreboot support 8 x 8Gb DDR3 UDIMMs 1600Mhz?
