Adjustments will be made based on the specifications of mass-produced memory products available on the market. * Non-ECC, un-buffered DDR5 memory supports 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 performance profile. Results may vary according to system components and can be impacted when four DIMM slots are used. For XMP/EXPO/AEMP profile settings, please visit https://www.asus.com/support/faq/1042256/. Graphics 1 x HDMI™ port** * Graphics specifications may vary between CPU types. Please refer to AMD CPU specifications. **Supports 4K@60Hz as specified in HDMI 2.1. *** VGA resolution support depends on processors' or graphic cards' resolution.
