Questions & Answers
What is the Lenovo ThinkSystem 64GB TruDDR4 2666 MHz LRDIMM (SKU 7X77A01305)?
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.
What are the key specifications of SKU 7X77A01305?
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.
Does this module support error-correcting code (ECC)?
Yes. The module features full ECC support to detect and correct single-bit errors, ensuring higher data integrity for mission-critical workloads.
Which Lenovo servers is this memory compatible with?
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.
How many memory ranks and banks does the module use?
The module uses a 4Rx4 architecture with four ranks of 16 GB dies, optimizing signal integrity and enabling higher capacity per DIMM.
What are the performance benefits of using this 64 GB TruDDR4 module?
By combining higher frequency and load-reduced buffering, this DIMM delivers increased bandwidth, reduced latency, and sustained throughput under heavy multitasking loads.
Can I mix Lenovo TruDDR4 LRDIMMs with RDIMMs in the same server?
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.
How do I install the 64 GB TruDDR4 2666 MHz LRDIMM?
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.
Is this memory module supported by Lenovo XClarity management tools?
Yes. Lenovo XClarity Controller and XClarity Administrator automatically detect, monitor, and report status for TruDDR4 LRDIMMs for seamless infrastructure management.
What warranty coverage comes with this Lenovo memory module?
Lenovo provides a three-year, customer-replaceable unit (CRU) warranty for the TruDDR4 LRDIMM, backed by global service and support.
Does the module comply with environmental and safety standards?
Yes. It meets RoHS, WEEE, and REACH environmental directives, and is UL- and CE-certified for enterprise data center deployment.
How does a load-reduced DIMM (LRDIMM) differ from a registered DIMM (RDIMM)?
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.
What use cases benefit most from this 64 GB TruDDR4 LRDIMM?
Ideal workloads include virtualization, in-memory databases, large-scale analytics, and high-performance computing that demand high capacity and reliability.
Can I upgrade existing Lenovo servers with SKU 7X77A01305 modules?
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.
What part number should I quote when ordering this memory?
Use Lenovo part number 7X77A01305 to ensure you receive the genuine 64 GB TruDDR4 2666 MHz (4Rx4 1.2 V) LRDIMM for ThinkSystem servers.
Where can I purchase genuine Lenovo ThinkSystem memory modules?
You can buy through Lenovo’s authorized resellers, channel partners, or the official Lenovo Premier site to guarantee authenticity and full support.
