Corsair has launched a series of registered memory modules with ECC designed for AMD’s Ryzen Threadripper 7000 and Intel’s Xeon W-2400/3400 series processors. The new Corsair WS DDR5 RDIMMs in AMD EXPO and Intel XMP 3.0 profiles will be available in kits with capacities up to 256 GB and speeds up to 6400 MT/s.
Corsair’s WS DDR5 RDIMM family includes 16 GB modules running up to 6400 MT/s with CL32 latency, and 32 GB modules running at 5600 MT/s with CL40 latency. Currently, Corsair offers four-channel 64GB kits (4×16GB, up to 6400 MT/s), four-channel 128GB kits (4×32GB, 5600 MT/s), and eight-channel 128GB kits (8×16GB, 5600 MT/s). ) and an eight-channel 256 GB kit (8×32GB, 5600 MT/s), it remains to be seen whether the company will expand the product lineup.
Corsair’s WS DDR5 RDIMM is designed for AMD’s TRX50 and WRX90 platforms and Intel’s W790 platform, making it compatible with AMD’s Ryzen Threadripper Pro 7000 and 7000WX series and Intel’s Xeon W-2400/3400 series CPUs. The module features both AMD EXPO and Intel XMP 3.0 profiles for easy setting beyond JEDEC specifications and features a thin heatsink made from pyrolytic graphite sheets (PGS), which has higher thermal conductivity than copper and aluminum of the same thickness . Currently, Corsair does not reveal which RCDs and memory chips it uses in its registered memory modules.
Unlike many of its rivals from leading DIMM manufacturers, Corsair didn’t launch its enthusiast-grade RDIMMs when AMD and Intel released their Ryzen Threadripper and Xeon W-Series platforms for extreme workstations last year. It’s hard to say exactly why, but perhaps the company wanted to gain experience using modules with registered clock drivers (RCD) with AMD and Intel’s extreme workstation platforms.
The results of the delay look well worth it: Unlike competitors’ modules that feature AMD EXPO or Intel XMP 3.0 profiles, Corsair’s WS DDR5 RDIMMs come with both profiles. While this may not matter in the DIY market where people know exactly what they are buying for their platform, this is a great feature for system integrators who can use Corsair WS DDR5 RDIMMs with their AMD Ryzen Threadripper and Intel Xeon W-Series builds, greatly simplifying their inventory management.
Since Corsair’s WS DDR5 RDIMMs are targeted at workstations and have been tested to provide reliable performance beyond JEDEC specifications, they are quite expensive. The cheapest 64 GB DDR5-5600 CL40 kit costs $450, the fastest 64 GB DDR5-6400 CL32 kit costs $460, and the highest-end 256 GB DDR5-5600 CL40 kit costs $1,290.
