64 GB DDR5 6000 quad-channel ECC kit

This Corsair WS RDIMM kit delivers 64 GB of DDR5 6000 memory across four 16 GB registered modules. It targets workstations that require error-correcting code for data integrity during high-end workloads. The CL40 latency and 1.35 V operating voltage support stable performance in demanding applications. Intel XMP 3.0 profiles simplify configuration on compatible platforms.

Registered 288-pin RDIMM build with heatspreader

Each module uses a 288-pin RDIMM form factor with a built-in heatspreader to manage thermals under sustained loads. Registered buffering reduces electrical load on the memory controller, allowing larger capacities per channel. The quad-channel kit layout matches workstation boards that populate four slots per processor. Modules are screened for reliable operation at the rated 6000 MT/s speed.

Verify DDR5 RDIMM support and XMP 3.0 BIOS option

Confirm your workstation motherboard accepts DDR5 registered DIMMs and supports quad-channel population rules before ordering. The platform must provide an Intel XMP 3.0 toggle or manual timing entry to reach 6000 MT/s CL40. Ensure the CPU memory controller is validated for 1.35 V registered modules at this frequency. Check maximum installed memory limits per socket.

商品問答

Does the DDR5 6000 PC5 48000 rating run at that speed on any motherboard, or is Intel XMP 3.0 required?

The kit is rated DDR5 6000 with timings 40-40-40-77 at 1.35 V. Intel XMP 3.0 applies those settings automatically in the BIOS; without XMP the modules will fall back to the platform default speed.

What slot type and module height does the 288-Pin DDR5 RDIMM need to fit in my workstation?

Each module is a standard 288-pin DDR5 RDIMM with an integrated heatspreader; it requires a DDR5 RDIMM slot and normal DIMM clearance — no extra height or proprietary connector.

What BIOS step enables the rated 6000 MT/s and CL40 timings on this quad-channel kit?

Enter the BIOS, locate the Intel XMP 3.0 profile for this kit, enable it, save and reboot; the common mistake is leaving XMP disabled so the memory runs at the lower JEDEC default instead.
