ASRock and MSI are now announcing support for 64GB DDR5 RAMs of higher capacity in each DIMM slot, allowing up to 256GB on four-slot motherboards and 128GB on two-slot motherboards. ASRock has also announced that it can do the same.
MSI did not reveal which of its motherboards include this support. The MSI screenshot shows CPU-Z results using the PRO X670-P WIFI motherboard. But ASRock showed its X670E-Taichi and the Z790 Nova WiFi with support for 64GB DDR5 per DIMM slot. Interestingly, ASRock is showing the AMD Ryzen 7 8700G APU with its X670E motherboard.
Both motherboard manufacturers use Kingston Fury Renegade KF560C36-64 64GB x 4 memory kits with DDR5 chips manufactured by Micron. We don’t know why MSI couldn’t provide a full-size screenshot, but ASRock provided screenshots showing support on both chipset platforms. These kits support EXPO and XMP 3.0 profiles, which support up to 6,000 MT/s with 36-38-38 latency at 1,350v.
This was made possible thanks to Micron and its 1-Beta node, which offers higher performance, greater bit density, and better energy efficiency. This new technology was originally designed for LPDDR5X mobile chips. It is likely that anyone making DDR5 RAM with Micron chips made from 1-Beta nodes will be able to provide higher capacity memory cards.
Although MSI and ASRock were the first to make the announcement, it is safe to say that other motherboard manufacturers with AMD X670E and Z790 chipsets should be able to support 64GB DDR5 kits per stick, which is currently possible with Micron. This is great for those with a mini-ITX motherboard with dual DIMM slots using these chipsets and who want higher capacity RAMs. It is uncertain whether this support will extend to X670 motherboards, as the only addition to X670E is support for sixteen PCIe 5.0 lanes through Ryzen 7000 series CPUs.
