Description

The Lenovo ThinkSystem 4X77A88052 is a high-performance 64GB DDR5 Registered DIMM (RDIMM) designed for the next generation of Lenovo ThinkSystem servers. Part of the TruDDR5 family, this memory module is specifically engineered and tested to exceed industry standards, ensuring maximum reliability and performance in mission-critical data center environments. With a clock speed of 5600MHz, it provides a massive increase in memory bandwidth compared to previous DDR4 generations, making it essential for AI, high-frequency trading, and massive virtualization workloads.

This module features a 2Rx4 (Dual Rank x4) organization, which is optimized for high-density memory configurations. As TruDDR5 memory, it includes a unique signature that allows Lenovo servers to verify the authenticity and integrity of the RAM, enabling advanced performance tuning and diagnostic features that are not available with third-party memory. It is a key component for ThinkSystem V3 servers powered by 4th and 5th Gen Intel Xeon Scalable processors.

Key Features

  • TruDDR5 Technology: Tested beyond JEDEC standards for 24/7 reliability and performance in Lenovo hardware.
  • High Speed (5600MHz): Delivers significantly higher data rates to support modern CPU architectures and bandwidth-heavy apps.
  • Error Correction (ECC): Advanced ECC and on-die ECC support to prevent data corruption and system crashes.
  • Dual Rank (2Rx4): Provides a balance of capacity and performance for high-density server configurations.
  • Power Efficient: DDR5 operates at a lower base voltage (1.1V) compared to DDR4, featuring on-DIMM Power Management ICs (PMIC).
  • Optimized for V3 Servers: Guaranteed compatibility with ThinkSystem SR630 V3, SR650 V3, and other Sapphire Rapids platforms.

Frequently Asked Questions

Q1: Can I mix this 5600MHz RAM with slower 4800MHz RAM?
A1: While technically possible, the system will down-clock all memory to the speed of the slowest module (4800MHz). For optimal performance, it is recommended to use identical speed modules.

Q2: What makes "TruDDR5" different from standard DDR5?
A2: TruDDR5 is Lenovo-certified memory. The server's UEFI can recognize the "Tru" signature, which unlocks extended diagnostic capabilities and ensures the memory has been tested specifically for ThinkSystem thermal and timing profiles.

Q3: Does this work in AMD EPYC based servers?
A3: This specific part number is primarily targeted at Intel-based V3 systems. While DDR5 is a standard, always check the Lenovo Press compatibility guide for your specific AMD (e.g., SR645 V3) model before purchasing.

Q4: Why 2Rx4 instead of 1Rx4?
A4: 2Rx4 (Dual Rank) allows for higher capacity modules (like 64GB) while maintaining high performance. It provides more memory banks for the CPU to access simultaneously compared to single-rank modules of the same capacity.
