Abstract
Memory reliability, performance and quality are even more critical today as customers utilize greater memory capacities for Big Data Analytics, Cloud Computing, Virtualization, Database and High Performance Computing workloads. Lenovo offers TruDDR4 Memory portfolio for ThinkSystem servers which help dramatically improve workload performance.
Change History
Changes in the March 1, 2022 update:
- Added the following UDIMMs for the ST50 V2, ST250 V2 and SR250 V2:
- ThinkSystem 8GB TruDDR4 3200 MHz (1Rx8, 1.2V) ECC UDIMM, 4X77A77494
- ThinkSystem 16GB TruDDR4 3200 MHz (2Rx8, 1.2V) ECC UDIMM, 4X77A77495
- ThinkSystem 32GB TruDDR4 3200MHz (2Rx8, 1.2V) ECC UDIMM, 4X77A77496
Introduction
ThinkSystem TruDDR4 Memory delivers trusted, tested, quality, performance, and reliability throughout the ThinkSystem portfolio. We use the highest quality industry-standard memory components sourced from Tier 1 DRAM suppliers. Only memory that meets these strict requirements are selected for TruDDR4 Memory. It is then compatibility tested and tuned on every ThinkSystem server to maximize reliability.
In addition, TruDDR4 Memory DIMMs have a unique signature programmed into them so your system can verify that TruDDR4 Memory is installed in your system. Since the memory will be authenticated, memory stretch goals are enabled only when TruDDR4 Memory DIMMs are detected. Together with lower power consumption, these new DIMMs can provide the lowest TCO for data centers.

High Performance Memory
Lenovo offers high-performance and high-capacity memory options in ThinkSystem servers.
Persistent Memory
Lenovo ThinkSystem servers configured with Intel Optane Persistent Memory transforms the memory/storage hierarchy enabling faster insights from data. This breakthrough technology delivers large capacity, high speed, affordable memory with data persistence and advanced encryption capabilities. These DDR4 compatible modules significantly increase the capacity of available system memory, keeping more hot data closer to the CPU, and enabling greater operational efficiency by processing larger data sets with more user instances.
3DS RDIMMs
To meet the ever increasing demand for higher density server memory modules, Lenovo offers 3DS (3 Dimensional Stacked) DDR4 RDIMMs which apply TSV (Through Silicon Via) technology from our partnership with a leading Tier 1 DRAM supplier. The new TSV 3DS stack technology enables higher density DRAM stack packages with higher operational frequency and reduced power consumption. The RDIMM configuration along with 3DS TSV DRAM packages exhibits performance benefits and lower power consumption over alternative high density solutions to ultimately provide the lowest TCO for data centers.
Performance+ Memory
Memory intensive workloads needing a competitive advantage will benefit from Lenovo’s Performance+ memory. Lenovo engineers worked in partnership with leading memory suppliers to develop and tune ThinkSystem servers enabling them to exceed the latest industry standard for memory performance. Lenovo’s Performance+ memory delivers increased bandwidth and lower latency at 2933 MHz with memory all channels fully populated.

Server Support
Configurations notes:
- Some 2666 MHz memory is only supported with Gen 1 Xeon Scalable processors (codenamed "Skylake"), whereas other 2666 MHz memory is only supported with Gen 2 Xeon Scalable processors (codenamed "Cascade Lake"). These are indicated with the (1) and (2) footnotes in the table, respectively.
- 2933 MHz memory is not supported by Intel Xeon SP Gen 1 processors
- The support of 32GB UDIMMs on ST50, ST250, SR150 and SR250 requires a Intel Xeon E Series processor and UEFI firmware ISE114H or later
- 2666 MHz Persistent Memory is only supported by Intel Xeon SP Gen 2 processors
- 3200 MHz Persistent Memory is only supported by Intel Xeon SP Gen 3 processors
- Some servers support mixing memory speeds; all memory will operate at the lowest speed
Note: Lenovo branded memory shipped as option part numbers, as FRU service parts, or installed in the factory as part of a CTO order, may contain memory parts that exceed the technical specification of what is printed on the DIMM label or is stated in the DIMM ordering information. Your server's system UEFI firmware may need to be updated to support such DIMMs. See Lenovo Support Tip HT509191 for additional information.

1 1. This item is not a general stand-alone option for Lenovo ThinkSystem SD650 (Xeon SP Gen 2), M/T 7X58 (Xeon SP Gen 2). 2. For OS support matrix, pls refer to LeSI Best Recipe. 3. This item shall be installed/removed by Lenovo support rep only.
2 When OCPMM (AEP) is installed, the maximum ambient temperature can be 30 °C. When operating above 30 °C, or in the event of a fan failure, the server will continue to function as long as all component temperature requirements are met, however, there may be performance reductions.Detail information please refer to Support Tip HT508512
