Description

The [Lenovo ThinkSystem 4X77A88051] is a high-reliability 32GB DDR5 Registered DIMM (RDIMM) designed specifically for the rigorous demands of modern data centers. As a member of the TruDDR5 series, this module undergoes testing beyond standard JEDEC requirements to ensure seamless compatibility and peak performance in Lenovo ThinkSystem hardware. With a clock speed of 5600MHz, it provides the low-latency and high-bandwidth memory access required for 4th and 5th Generation Intel Xeon Scalable processors.

The 4x77a88051 features a 2Rx8 (Dual Rank) architecture, providing a stable and efficient memory configuration for enterprise servers. TruDDR5 memory includes a unique digital signature that enables Lenovo servers to verify the authenticity of the module, unlocking advanced system tuning and diagnostic capabilities within the UEFI. This ensures that your thinksystem v3 ram investment is protected and performing at its maximum potential.

Frequently Asked Questions

Q1: Can I use this RAM in a non-Lenovo server?
A1: While DDR5 is a standard, TruDDR5 is specifically tuned for Lenovo's BIOS/UEFI. In a third-party server, it may function as standard DDR5, but you will lose the advanced Lenovo-specific diagnostic and performance-tuning features.

Q2: What is the benefit of 5600MHz over 4800MHz?
A2: 5600MHz offers roughly a 16% increase in theoretical bandwidth, which translates to faster data processing for memory-bound applications like high-performance computing (HPC) and complex simulations.

Q3: Is this module compatible with older V2 ThinkSystem servers?
A3: No. V2 servers use DDR4 memory. This DDR5 module is exclusively for V3 servers and newer platforms that support the LGA-4677 or LGA-7529 sockets.
