64GB DDR5-5600 ECC Registered DIMM

This SK hynix module provides 64GB of DDR5 SDRAM in a 288-pin registered form factor. It operates at 5600 MT/s with a CAS latency of CL46 and a voltage of 1.1V. The dual-rank design includes error-correcting code for data integrity in critical workloads.

For Servers and Workstations Requiring Registered

This memory suits systems that mandate registered ECC DDR5 modules at the 5600 speed grade. It is not for desktop boards that accept only unbuffered non-ECC DIMMs. Buyers needing lower latency timings or different voltage specifications should verify platform requirements before purchase.

Dual Rank 64GB Density Decides Fit

The single specification that determines compatibility is the 64GB dual-rank organisation combined with registered ECC DDR5 at 5600 MT/s. Your motherboard and CPU memory controller must explicitly support this exact density, rank structure and registered signalling.

商品問答

Does the 288-pin DDR5 form factor fit standard server DIMM slots?

Yes, the 288-pin DDR5 design matches the standard registered DIMM slot used in compatible server and workstation platforms.

What is the correct seating procedure for the registered ECC module?

Align the module notch with the slot key, press firmly until both locking tabs click, and verify the registered buffer engages before applying power.

When should the 64GB dual-rank module be replaced?

Replace the module if system diagnostics report uncorrectable ECC errors, persistent memory test failures, or the hardware enters a degraded memory state.
