Zen 6 Ryzen Medusa to Get Dual Memory Controllers and Changed DIMM Orientation

There are new details about processors Next Gen AMD Ryzen on Zen 6 architecture, who received the code name Medusa. According to a leak from Chinese forums, confirmed by a source at Uniko's Hardware, the chips will be equipped with two memory controllers, which will lead to changing the preferred configuration of DDR5 modules.

According to insiders, one of the new integrated memory controllers (IMC) will only support 1 DIMM per channel (1DPC), which will limit the use to two strips in the corresponding configurations. This directly affects the starting and optimal installation of memory modules.

If AM5 boards are now slot-oriented A0 and B0, then in Zen 6 the emphasis is shifts to A1 and B1, especially in dual-slot configurations such as Mini-ITX and mATX. At the same time, AM5 boards with four slots (A2/B2 and A1/B1) will remain compatible, but the optimal installation will be in A1 and B1, and not in A2 and B2, as before.

It is also known that AMD plans to provide limited compatibility with older A0/B0 slots, however performance will be lowerthan when using the new scheme. It has already been confirmed that the motherboard MSI MPOWER AM5 Supports new DIMM configuration.

Ryzen Medusa with Zen 6 architecture is expected to be released in 2026 year and will bring growth productivity, new cache solutions и changes in the number of cores, but the key changes will affect precisely memory subsystem.
