ASUS AEMP III increases support for up to 4x DIMMs with 64 GB CUDIMM DDR5 modules on Intel 800-series motherboards.

AEMP III Now Offers Support for up to 256 GB Memory Configuration, Clocked at 5600 MT/s on Intel 800-Series Motherboards

Memory makers have been competing with each other fiercely, bringing incredibly high-frequency DDR5 memories. We saw this in previous months, with several memory manufacturers releasing their CUDIMMs with insanely high transfer speeds, exceeding even 10000 MT/s and in some cases breaking the 12000 MT/s mark with overclocking.

What remained a challenge is the support for higher memory capacity. Higher frequency is generally achieved with single DDR5 RAM sticks and with dual sticks, the RAM frequencies would hardly touch 10000 MT/s. Now talking about 4x DIMMs, achieving high memory frequency is even more difficult, and adding four DIMMs, particularly CUDIMMs, increasing capacity and memory frequency are both big challenges.

Today, ASUS announced new support for this type of configuration. With the launch of an upgraded AEMP feature, ASUS Enhanced Memory Profile III, ASUS has offered support of up to 64 GB CUDIMM DDR5, and that too at 5600 MT/s, which was previously limited to 4400 MT/s. That said, the previous AEMP III feature would only support 2x DIMM configuration and the latest version allows 4x DIMM config on the Intel 800-series motherboards such as Z890 and B860 models.

ASUS illustrated by using a Core Ultra Series 2 processor on the ROG Maximus Z890 Extreme motherboard. It added a 4x 64 GB Kingston memory kit, clocked at 5600 MT/s, which was achieved through the AEMP III Profile. Note that this is right now exclusive to Kingston 64 GB CUDIMM DDR5 modules and once you add these to your ASUS 800 series motherboards, your BIOS will enable the AEMP III feature in the AI Overclock Tuner option.

Once you get that option enabled, you can enjoy up to 27% higher performance than the DDR5-4400 memory kit as per ASUS’s claim. The company hasn’t demonstrated any results or shown any benchmark numbers, but 1200 MT/s should have noticeable performance uplifts in select apps and games. It shouldn’t be much, and we don’t know in which app or operation, ASUS achieved a 27% performance uplift.

Nonetheless, the presence of a clock driver on CUDIMMs offers better stability than regular DIMMs, and now the mainstream Intel-based desktop PCs should be able to offer a decent workstation-like experience.
