Lenovo - TruDDR4 - DDR4 - module - 64 GB - DIMM 288-pins - 3200 MHz / PC4-25600 1,2 V registered ECC

The Lenovo 4X77A08635 Memory Module is a 64 GB DDR4 3200 MHz 288-pin DIMM designed for PCs and servers. It provides high-capacity system memory with a 1.2 V operating voltage to support demanding applications and multitasking. Compatible with DDR4 platforms, this module helps increase available memory to keep more active data near the CPU and improve overall system responsiveness.

Advantages

This 64 GB DDR4 3200 MHz module delivers a balance of capacity and performance suitable for memory‑intensive workloads. Its 288‑pin DIMM form factor ensures compatibility with standard DDR4 slots, while the 1.2 V operating voltage supports efficient power usage. Using higher capacity modules like this reduces the need for multiple DIMMs, simplifies upgrades, and can lower total cost of ownership in dense deployments.

Suitable for

• PC and workstation upgrades requiring large RAM capacity
• Server memory expansion for virtualization and database workloads
• Memory‑intensive applications such as large datasets, analytics, and content creation
