Woah! Just imagine the speed you’ll get out of this. I’ve played with a quad-channel DDR4 system in the past … and it’s fast! With a 12-channel DDR5 system, it’s going to rocket!
Taken from TPU … Thanks to a Linux driver update, we now know that AMD’s upcoming Zen 4 based EPYC CPUs will support up to 12 channels of DDR5 memory, an upgrade over the current eight. The EDAC driver, or Error Detection and Correction driver update from AMD contained details of the memory types supported by AMD’s upcoming server and workstation CPUs and although this doesn’t tell us much about what we’ll see from the desktop platform, some of this might spill over to a future Ryzen Threadripper CPU.
The driver also reveals that there will be support for both RDDR5 and LRDDR5, which translates to Registered DDR5 and Load-Reduced DDR5 respectively. LRDDR5 is the replacement for LRDIMMs, which are used in current servers with very high memory densities. Although we don’t know when AMD is planning to announce Zen 4, even less so the new EPYC processors, it’s expected that it will be some time in the second half next year.
