Lexar ARES RGB LD5U16G72C34LA 16GB DDR5-7200 CL34 Review

This single 16GB Lexar ARES RGB module runs a high DDR5-7200 CL34

Performance

CL34 at 7200MT/s computes to 9.4ns true latency, beating AM5's 6000MT/s CL30 sweet spot on paper while offering significantly more bandwidth, best realized on Intel's memory controller.

Compatibility

7200MT/s exceeds the 1:1 fabric-ratio ceiling most AM5 boards hold; Intel Z790/Z890-class boards run this speed without that ratio penalty.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

  • Intel builds wanting high bandwidth with tight latency
  • Content creation or compilation workloads benefiting from raw bandwidth

Not for

  • AM5 builds, where 6000-6400MT/s stays inside the efficient 1:1 ratio
  • Budget builds where a 6000MT/s module is close enough on real-world latency
