Lenovo SR685a V3 512GB DDR5 kit

This 512GB kit contains four 128GB DDR5 5600 registered DIMMs built for the Lenovo ThinkSystem SR685a V3 rack server. IT teams buying for virtualisation hosts or database nodes get ECC protection and registered signalling in a single validated package. The modules run at 1.1V with CL46 latency and use a 4Rx4 organisation.

DDR5 5600 registered ECC limits

The DDR5 5600 standard tops out at 5600 MT/s and the registered buffer adds one cycle of command latency compared with unbuffered modules. ECC corrects single-bit errors and detects double-bit errors but cannot repair them. Four ranks per DIMM increase electrical loading so the memory controller must support 4Rx4 population rules.

288-pin RDIMM build and daily fit

Each stick is a plain 288-pin RDIMM without a heat spreader so airflow in dense server chassis passes directly over the DRAM. The 1.1V operating voltage matches the DDR5 baseline and keeps power draw predictable. Registered signalling and ECC mean the modules only work in platforms wired for registered ECC memory.

商品問答

Should I choose the 512GB kit with four 128GB modules or a different capacity for my SR685a V3?

This kit provides 512GB total using four 128GB DDR5 5600 CL46 ECC RDIMMs; choose it when your workload needs maximum registered capacity in four slots.

What does the 5600 speed rating deliver once installed in the server?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, giving the rated throughput and timing the platform negotiates for registered ECC memory.

How does the 288-pin DDR5 RDIMM interface affect compatibility and bandwidth limits?

The 288-pin registered DIMM fits the SR685a V3 DDR5 slots; the 4Rx4 organisation and ECC function operate within the server memory controller's supported ranks and error-correction capability.
