GIGABYTE’s X870i AORUS PRO ICE motherboard is getting an update, with Revision 1.1 reportedly bringing a fresh memory configuration aimed at Zen 6 processors. This is a major step forward as Zen 6 chips will feature dual memory controllers (IMCs), shifting the supported memory layout from the traditional A1B1 to A2B2. This change will ensure better signal integrity and stability, particularly with higher frequency RAM kits. 
MSI previously made similar moves with its B850 series motherboards, but GIGABYTE’s X870i AORUS PRO ICE is now the next to follow suit.
What’s important here is that the new configuration will only be available on four DIMM-slot motherboards. The A1B1 setup seen in earlier models, including Rev 1.0 of the X870i, isn’t compatible with the upcoming Zen 6 chips. The switch to A2B2 ensures that Zen 6 processors, which will only run with this configuration initially, can handle more advanced memory setups. While it’s expected that future updates will bring A1B1 compatibility, for now, the Zen 6 lineup is locked into the A2B2 memory configuration.
Interestingly, this design change also paves the way for AMD’s Zen 6 processors to include up to 12 cores on a single CCD, breaking the long-standing 8-core ceiling. With the new dual CCDs and dual I/O Dies, memory performance should see significant improvements. It’s all part of AMD’s push for more power and efficiency with its next-gen processors.
