SK hynix HMCG94AGBRA177N 64GB DDR5-5600 RDIMM ECC Reg Dual Rank server RAM
A 64 GB DDR5-5600 ECC registered RDIMM with dual-rank 2Rx4 organisation and CL46 latency for server workloads
- 64 GB capacity supports data-intensive server workloads
- DDR5-5600 speed delivers 44800 MT/s bandwidth
- ECC Registered design corrects errors for enterprise reliability
- Dual-rank 2Rx4 organisation increases memory density per slot
- CL46 latency at 1.1 V optimises responsive performance
Capacity and role
This 64GB DDR5 module delivers registered ECC memory for servers and workstations running data-intensive workloads. The dual-rank 2Rx4 organisation increases density per slot while maintaining error correction for enterprise reliability.
Thermal and power behaviour
Operating at 1.1 volts, the RDIMM draws less power per gigabyte than earlier generations during typical server duty. Standard airflow across the 288-pin module keeps temperatures within specification without exotic cooling.
What the spec changes
ECC registration corrects single-bit errors and detects multi-bit faults, reducing silent data corruption in critical applications. CL46 latency at 5600 MT/s balances throughput and stability for virtualisation, database and high-performance computing tasks.

Perguntas sobre este artigo
How do I install this 288-pin RDIMM and which step is often missed?
Align the key notch with the DDR5 slot, press firmly until both retention clips click, and ensure the server is fully powered off — not just in standby — so the ECC registers initialise correctly on first boot.
What maintenance or replacement will this 64 GB DDR5-5600 module need over its service life?
No routine maintenance is required; if a correctable ECC error count rises above the platform threshold, replace the module, otherwise it runs for the server's lifetime without service.
What limit appears first when this CL46 dual-rank RDIMM runs sustained workloads?
The CL46 CAS latency at 5600 MT/s sets the timing ceiling; sustained bandwidth is capped by the 44800 MB/s data rate before thermal or power limits are reached.
