System-Specific DDR5 Kit
This 256 GB kit contains two 128 GB registered DIMMs built for the Lenovo ThinkSystem SR780a V3 rack server. ECC and register circuitry protect data integrity in mission-critical workloads. The modules run at 5600 MT/s with a CAS latency of 46 at 1.10 V.
DDR5 5600 Interface Limits
The PC5-44800 standard tops out at 5600 MT/s, so this kit cannot exceed that transfer rate without a platform that officially supports higher JEDEC speeds. Registered buffering adds one cycle of command latency, which is normal for server memory. Four-rank organisation increases density but may restrict maximum population on some boards.
ECC RDIMM Build and Connectors
Each 288-pin module uses major-brand Samsung, Micron or Hynix chips without a heat spreader, relying on chassis airflow for cooling. The registered design places a buffer between the DRAM and the memory controller, reducing electrical load. Installers must match the keyed notch and populate slots in the order the server manual specifies.

이 상품에 대한 질문
Should I choose the 256GB kit with two 128GB modules or a different capacity for my ThinkSystem SR780a V3?
This kit provides 256GB total across two 128GB RDIMMs, matching the 4Rx4 rank structure and 1.1V voltage specified for the SR780a V3 memory slots.
What does the DDR5 5600 speed rating mean for actual throughput in this server?
The PC5-44800 designation indicates a peak transfer rate of 44800 MT/s, which the memory controller will use when the platform runs at the rated 5600 frequency.
How does the 288-pin ECC RDIMM interface limit what I can install alongside this kit?
The modules are 288-pin DDR5 RDIMMs with ECC and registered buffering, so they only fit DDR5 RDIMM slots that support 4Rx4 organisation and 1.10V operation.
