Gigabyte is testing 192GB memory on their X670E series
Overclocked 4x 48GB DDR5-6000 memory works on Gigabyte X670E motherboard.
It is not just ASUS who is developing new BIOSes for AMD 600-series chipsets. The new firmware for Gigabyte motherboards is said to enable non-binary memory support on their AMD AM5 platform.
The official AGESA update for AMD X670 and B650 motherboards that enables non-binary memory support is likely to be released soon. Both ASUS and now Gigabyte have been testing (and teasing) early BIOSes that enable 24/48 GB memory support on the AMD platform. This type of memory is already supported by Intel 600 and 700 series, for which manufacturers have released a BIOS update.
According to the post shared on Coolaler forums, AORUS X670E Master may support up to 192GB of memory. What is important is that this memory was running at 6000 MT/s speed. A community member, JHL88 has also published a 2-hour long MemTest results that show no errors. This is a clear indicator that the memory support is there, but whether it actually works in software other than synthetic benchmarks is something that still needs to be verified.
The first non-binary DDR5 memory kits have already gone on sale, companies like CORSAIR or G.SKILL have already released their Vengeance and Trident Z5 series offering up to 48GB and DDR5-8000 kits. These uncommon 24GB and 48GB capacities are aimed at users who are seeking more options, or simply want more capacity (48GB modules enable 192GB max capacity).
It is rumored that the 24G/48G firmware may be released in April, but neither AMD nor Gigabyte have confirmed their plans.
