About Corsair WS DDR5 6000MT/s CL40
Corsair WS DDR5-6000 CL40 is the mid-tier option in Corsair's workstation ECC RDIMM lineup, running at 6000MT/s with CL40-40-40-77 timings at 1.35V. Same ECC registered design as the 5600MT/s kit but with 7% more bandwidth at the cost of slightly higher voltage.
Incremental Bandwidth Gain
The jump from 5600MT/s to 6000MT/s adds roughly 7% more memory bandwidth while keeping the same CL40 timings. In practice, this matters for memory-bandwidth-sensitive workloads like large matrix operations, video editing timeline scrubbing, and multi-VM environments where memory throughput is the bottleneck. For general workstation use, the difference versus 5600MT/s is marginal.
Platform and Voltage
Validated on Intel W790 boards (ASUS Pro WS W790E-SAGE SE, ASRock W790 WS). Intel XMP 3.0 profile required for rated speed; SPD default runs at 4800MT/s/1.1V. The 1.35V operating voltage is higher than the 5600MT/s kit's 1.25V, which increases heat output slightly. Confirm your board supports 6000MT/s with RDIMMs before buying; some W790 boards only guarantee 5600MT/s.
Available in 64GB (4x16GB) kits. PGS heat spreader, iCUE compatible. Limited lifetime warranty.
Best for: Workstation builds where you want more bandwidth than 5600MT/s without jumping to the 6400MT/s tier's tighter timing requirements and higher price.
Avoid if: The 5600MT/s kit is significantly cheaper. The 7% bandwidth increase rarely justifies a large price premium. Or if you want the best performance in this lineup, look at the 6400MT/s CL32 kit instead.
