ASUS Enhanced Memory Profile (AEMP)

* Supported memory types,
data rate (speed), and number
of DRAM modules vary
depending on the CPU and
memory configuration.

For more information,
please refer to the CPU/Memory
Support list under the Support
tab of the product information site
or visit https://www.asus.com/support/download-center/. Adjustments will be made based on the specifications of mass-produced memory products available on the market.

* Non-ECC, un-buffered DDR5
memory supports the On-Die ECC function.

** Max Manual Overclocking:
Achievable with advanced BIOS
configuration and potentially specialized
hardware. Passed AIDA64 memory benchmark at this frequency, verifying read/write bandwidth.

Results may vary according to system components.

*** XMP/EXPO/AEMP Profiles: Rated memory module speeds require setting the BIOS perormance profile.
