The Lenovo ThinkSystem 64GB TruDDR4 2666 MHz LRDIMM (SKU 7X77A01305) is a single‐rank, load-reduced DIMM designed for enterprise servers, offering 64 GB of ECC‐protected memory at 2,666 MHz and 1.2 V.
Key specifications include 64 GB capacity, 2,666 MHz frequency, 1.2 V operating voltage, 4Rx4 rank configuration, ECC support, and a standard 288-pin LRDIMM form factor.
Yes. The module features full ECC support to detect and correct single-bit errors, ensuring higher data integrity for mission-critical workloads.
This LRDIMM is validated for all Lenovo ThinkSystem rack and tower servers that support 2,666 MHz DDR4 LRDIMM, including the SR, ST, and SN series platforms.
The module uses a 4Rx4 architecture with four ranks of 16 GB dies, optimizing signal integrity and enabling higher capacity per DIMM.
By combining higher frequency and load-reduced buffering, this DIMM delivers increased bandwidth, reduced latency, and sustained throughput under heavy multitasking loads.
No. Mixing LRDIMMs with RDIMMs or UDIMMs is not supported. All memory modules must be of the same type to ensure proper signaling and stability.
Power down the server, remove the access panel, align the module with the keyed slot, press firmly until the latches click, then reassemble and power on.
Yes. Lenovo XClarity Controller and XClarity Administrator automatically detect, monitor, and report status for TruDDR4 LRDIMMs for seamless infrastructure management.
Lenovo provides a three-year, customer-replaceable unit (CRU) warranty for the TruDDR4 LRDIMM, backed by global service and support.
Yes. It meets RoHS, WEEE, and REACH environmental directives, and is UL- and CE-certified for enterprise data center deployment.
LRDIMMs include on-module buffers for both address/command and data lines, reducing electrical load on the memory bus and enabling higher capacity and performance versus RDIMMs.
Ideal workloads include virtualization, in-memory databases, large-scale analytics, and high-performance computing that demand high capacity and reliability.
Yes. Provided your server model supports 2,666 MHz DDR4 LRDIMMs, you can install this module to expand capacity without BIOS updates in most ThinkSystem releases.
Use Lenovo part number 7X77A01305 to ensure you receive the genuine 64 GB TruDDR4 2666 MHz (4Rx4 1.2 V) LRDIMM for ThinkSystem servers.
