Capacity and fit

This single module provides 64GB of DDR5 memory for the Lenovo ThinkSystem SD530 V3. It is built as a 288-pin ECC Registered RDIMM with a 2Rx4 organisation and operates at 1.1V. The part is intended for server and workstation platforms that require registered ECC memory. It will not work in standard desktop computers or in systems that use unbuffered or load-reduced DIMMs.

Interface limits

The module runs at DDR5 5600 speed with a CAS latency of 46 and conforms to the PC5-44800 standard. Registered ECC memory adds a clock cycle for command buffering, so it cannot be mixed with unbuffered or load-reduced modules in the same system. JEDEC compliance ensures electrical and timing compatibility with the qualified platform. Maximum capacity and population rules are defined by the server documentation.

Pre-installation checks

Verify that the Lenovo ThinkSystem SD530 V3 supports 64GB Registered RDIMMs and the 2Rx4 rank configuration in the desired slot layout. Confirm the firmware revision meets the vendor's minimum for DDR5 5600 operation. Ensure all installed DIMMs share the same registered ECC type to avoid mixing incompatible module classes.

Perguntas sobre este artigo

Should I pick the 64GB module or add multiple sticks for the ThinkSystem SD530 V3?

This is a single 64GB DDR5 5600 CL46 2Rx4 registered ECC RDIMM; the SD530 V3 accepts registered ECC DDR5, so choose the number of modules that matches your target capacity and the server's slot count.

What does the 5600 MT/s rating deliver once installed in the SD530 V3?

The module runs at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, giving the server its rated bandwidth and error-corrected throughput for workloads that the platform supports.

Is the 288-pin DDR5 ECC registered RDIMM interface the limiting factor for speed in this server?

The 288-pin registered ECC DDR5 form factor carries the 5600 MT/s signal; actual operating speed is capped by the SD530 V3's memory controller and any population rules it enforces.
