32 GB DDR3L ECC registered RDIMM kit for Lenovo ThinkServer RD540, RD630, RD640, TD330 and TD340
Capacity 32GB (4 x 8GB)
This kit provides 32GB of DDR3L ECC registered memory in four 8GB modules built for Lenovo ThinkServer RD540, RD630, RD640, TD330 and TD340 systems. It is designed for server and workstation workloads that require error correction and registered buffering. Standard desktop computers cannot use this memory type.
Verify that your ThinkServer model appears in the supported list before ordering. The modules are 240-pin DDR3L RDIMMs operating at 1.35V with CL11 latency and 1Rx4 organisation. They must not be mixed with unbuffered DIMMs and the platform must accept registered ECC memory.
Each module uses a standard 240-pin DDR3L form factor without a heat spreader, allowing dense slot population in compatible chassis. The registered design adds a buffer that reduces electrical load on the memory controller during heavy multitasking. JEDEC and RoHS compliance confirms baseline manufacturing quality.
