Lexar ARES Gen2 RGB LD5U24G80C40LW 24GB DDR5-8000 CL40 Review
This single 24GB Lexar ARES Gen2 RGB module runs an extreme DDR5-8000 CL40
the fastest-rated ARES Gen2 RGB SKU in this catalog, requiring a high-end Intel board and memory controller to run at spec.
Performance
CL40 at 8000MT/s computes to 10.0ns true latency, matching AM5's 6000MT/s CL30 sweet spot while adding considerably more bandwidth for workloads that use it.
Compatibility
8000MT/s requires a well-validated high-end Intel board and CPU memory controller; expect this to fall back to a slower ratio on any AM5 system, since it's well past most AM5 boards' 1:1 ceiling.

Best for
- High-end Intel builds chasing maximum bandwidth with RGB styling
- Bandwidth-sensitive workstation or content-creation workloads
Not for
- AM5 builds, where this speed is far outside the efficient ratio range
- Mainstream builds where 6000MT/s is more than sufficient
