Product Overview
The Lenovo 01KR356 is a ThinkSystem 64GB TruDDR4 DDR4 RDIMM memory module rated at 2933 MHz with a 2Rx4 rank configuration and 1.2 V operating voltage. It’s designed for enterprise server environments where validated compatibility and predictable stability are essential, making it a practical upgrade for virtualisation hosts, database servers, and in-memory caching.
Memory performance and supported speeds depend on the server platform, CPU generation, and BIOS/DIMM population rules. For balanced upgrades within ThinkSystem architectures, this module is typically deployed alongside the host SYSTEM BOARD and compatible CPU options to maintain supported configurations and avoid downclocking.
This part is intended for Lenovo ThinkSystem platforms that support 2933 MHz DDR4 RDIMMs. Common examples include ThinkSystem SR550, SR590, and SR650, as well as selected ST-series tower systems (final compatibility depends on the exact server configuration and firmware).
Key Features
Key technical characteristics and deployment benefits of this ThinkSystem memory module:
- 64GB DDR4 RDIMM capacity to expand system memory for virtualisation, consolidation, and memory-intensive applications.
- 2933 MHz speed rating to support higher memory bandwidth in compatible ThinkSystem configurations.
- 2Rx4 (dual-rank x4) organisation to align with common enterprise DIMM population schemes for stability and performance.
- 1.2 V operating voltage to match standard DDR4 power characteristics in server environments.
- Lenovo ThinkSystem TruDDR4 module design to support server-grade operation for 24/7 workloads.
- Compatibility focus for Lenovo ThinkSystem servers supporting 2933 MHz DDR4 RDIMMs, including SR550/SR590/SR650 and selected ST-series models (CPU/BIOS dependent).
- RDIMM form factor to support scalable memory configurations across multiple channels and slots in enterprise platforms.
- Well-suited for VM hosts, application servers, and database nodes to reduce memory pressure and swapping under load.
Refurbished Quality and Warranty
This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished memory is a practical way to extend the lifecycle of existing Lenovo ThinkSystem infrastructure, reduce electronic waste, and control budget compared to buying new.
All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware shipping worldwide from Denmark.
