Lexar LD5U32G56C46ST 32GB Review
This single 32GB Lexar module runs DDR5-5600 CL46 with no RGB lighting
a plain, budget-tier UDIMM without a named retail sub-line, just a straightforward high-capacity stick.
Performance
CL46 at 5600MT/s is 16.4ns true latency, the loosest bin among the Lexar 32GB parts covered in this catalog; this is a capacity-first, timing-second module.
Comparison to Alternatives
The Lexar ARES Gen2 RGB LD5U32G64C32BR in this catalog runs at 10.0ns, meaningfully faster; choose this plain UDIMM specifically when a lower price matters more than latency and RGB isn't wanted.
