Will this memory work with my TR 1920X on X399 Taichi? M391A4G43MB1-CTD (32GB ECC UDIMM) [URL=https://www.samsung.com/semiconductor/dram/module/M391A4G43MB1-CTD/]Samsung M391A4G43MB1-CTD[/URL] Many thanks, The Buell |

To get a definitive answer you will need to contact ASRock Tech Support: https://event.asrock.com/tsd.asp It is an unbuffered ECC RAM module so in theory it should work but the 32gb capacity may require a BIOS update, I can't be sure. I suspect it will work but I wouldn't take my word for it, these things are not cheap. ASRock Tech Support should be able to tell you for sure but you may have to wait till January 2nd or later for a response. -------------

Just heard from Asrock support. They say it should work but they have not tested with it. I've just ordered a pair of them, should be with me Monday. Will be nice to have all that memory as at full throttle it runs out of memory whilst parallel compiling code! :-S |
