About Corsair WS DDR5 5600MT/s CL40
Corsair WS DDR5-5600 CL40 is workstation-grade ECC registered memory running at 5600MT/s with CL40-40-40-77 timings at 1.25V. It's designed for AMD TRX50/WRX90 (Threadripper PRO) and Intel W790 (Xeon W-3400/W-2400) workstation platforms.
ECC RDIMM for Workstations
Full ECC with registered buffering. This is real error-correcting memory, not the on-die ECC that all DDR5 includes. For workstation tasks involving large datasets, 3D rendering, scientific computation, and CAD, ECC protection prevents silent data corruption that can waste hours of compute time. The registered design supports the high DIMM counts these platforms offer (up to 8 channels on WRX90).
Platform Compatibility
Validated on AMD TRX50 and WRX90 boards (ASUS Pro WS WRX90E-SAGE SE, Pro WS TRX50-SAGE WIFI, Gigabyte TRX50 AERO D) and Intel W790 boards (ASUS Pro WS W790E-SAGE SE, ASRock W790 WS). Supports both Intel XMP 3.0 and AMD EXPO profiles. SPD default is 4800MT/s at 1.1V; rated speed requires enabling the XMP/EXPO profile.
Kit Options
Available in 64GB (4x16GB) and 128GB (4x32GB) kits. PGS heat spreader design for thermal management in workstation airflow environments. iCUE compatible. Limited lifetime warranty.
Best for: Threadripper PRO and Xeon W workstation builds that need ECC protection at DDR5 speeds. The 5600MT/s tier is the baseline WS DDR5 speed and offers the broadest platform compatibility.
Avoid if: You're building a desktop or gaming PC. These are RDIMMs and won't work in consumer motherboards. For non-ECC DDR5, look at the standard Vengeance DDR5 UDIMM line.
