ASUS adds support for 64GB memory modules to Intel 600/700 motherboards

Asus said on Thursday that it has released a new version of UEFI BIOS for Intel 600/700 series motherboards that support DDR5 and can support 64 GB DIMMs.As such, Asus’ latest Intel 12 platformth13th and 14th New generation Core processors with four DIMM slots can now support up to 256 GB of DDR5 memory, and motherboards with two DIMM slots can now support up to 128 GB of memory.

To get support for 256 GB DDR5 memory using 64 GB unbuffered DIMMs, you need to download the latest version of UEFI BIOS for one of the Intel 600/700 series motherboards listed on the ASUS website.

ASUS motherboards use the LGA1700 socket and support 256 GB DDR5 memory, and include 75 motherboards based on various Intel 600 and 700 series chipsets, including Intel Z790, H770, B760, Z690, W680 and Q670.Despite reviewing ASUS’s larger motherboard offerings, this is still a bit hard to cover all There are nearly 200 models of ASUS LGA1700 motherboards in total. So, at least for now, only a small subset of motherboards support 64 GB DIMMs.

Otherwise, it’s worth noting that cutting-edge high-capacity DIMMs (such as 32 GB, 48GB, and 64 GB) often don’t have the same XMP clock speeds as some of their lower-capacity counterparts, so equipping an Intel system with 256 GB of memory will result in peak memory bandwidth The trade-off is in addition to the typical DDR5 2 DIMM per channel (2DPC) frequency penalty. In fact, the fastest 48 GB modules currently offered by Corsair and G.Skill (which can be used to build systems with 192 GB of memory) top out at 6600 MT/s and 6800 MT/s respectively. At the same time, these two well-known manufacturers have not yet launched 64 GB DDR5 modules compatible with Intel XMP 3.0.

Ultimately, the primary market for high-capacity UDIMMs today will be content creators, data scientists, and other workstation lightweight workloads that require a quarter of a terabyte of RAM and can justify the cost of leading DIMMs. Otherwise, the 16 GB and 32 GB DIMMs will likely remain the best choices for the LGA1700 platform for the remainder of its life.

Finally, it should be noted that Asus also announced (or rather reiterated) that its AM5 motherboards support 64 GB DIMMs. That said, this support is baked into the platform and BIOS, and unlike Intel boards, no BIOS update is required.
