Other than ASUS, Gigabyte is also working on developing new BIOSes for AMD 600-series chipsets. According to reports, the upcoming firmware for Gigabyte motherboards is expected to introduce non-binary memory support for their AMD AM5 platform.
An official AGESA update for AMD X670 and B650 motherboards, which will enable non-binary memory support, is expected to be released soon. Both ASUS and Gigabyte have been testing and giving hints about early BIOSes that will allow 24/48 GB memory support on the AMD platform. The memory type is already supported by Intel 600 and 700 series, and manufacturers have already released a BIOS update for it.
A post on the Coolaler forums has suggested that the AORUS X670E Master has the potential to support a maximum of 192GB of memory running at 6000 MT/s speed. A community member named JHL88 has conducted a 2-hour long MemTest, which demonstrated no errors. While this indicates that the memory support exists, it remains to be seen if it works properly with software other than synthetic benchmarks.
Leading companies like CORSAIR and G.SKILL have launched their first non-binary DDR5 memory kits, including the Vengeance and Trident Z5 series, which offer up to 48GB and DDR5-8000 kits. These memory kits have unusual capacities of 24GB and 48GB, which are intended for users who desire more options or require additional capacity (48GB modules allow for a maximum capacity of 192GB).
There are rumors that the 24G/48G firmware may be released in April, but neither AMD nor Gigabyte have confirmed their plans yet.
