Description

The Lenovo ThinkSystem 64GB TruDDR4 Performance+ RDIMM is a server-grade DDR4 memory module purpose-built for Lenovo ThinkSystem SR-series rack servers. Operating at 2933MHz (PC4-23400) with a dual-rank 2Rx4 architecture and 1.2V low-voltage design, it delivers high-density, high-throughput memory capacity for demanding enterprise workloads including virtualisation, in-memory databases, and analytics. The registered (buffered) design ensures superior signal integrity across multi-DIMM configurations, while ECC support actively detects and corrects memory errors to safeguard data integrity in mission-critical environments. As a genuine Lenovo ThinkSystem-optimised module, the 4X77A12186 integrates seamlessly with Lenovo's server firmware and management tools for validated, reliable performance. Whether you're scaling memory in a new ThinkSystem deployment or expanding capacity in an existing infrastructure, this 64GB RDIMM provides the headroom your workloads demand.

FAQs

Q: Which Lenovo servers is the 4X77A12186 compatible with?
A: The 4X77A12186 is designed for Lenovo ThinkSystem SR-series rack servers that support DDR4 RDIMMs running at 2933MHz. Always verify compatibility with your specific server model using Lenovo's ServerProven compatibility tool before purchasing.

Q: What does 'TruDDR4 Performance+' mean?
A: TruDDR4 Performance+ is Lenovo's designation for memory modules that are validated, tested, and optimised specifically for ThinkSystem server platforms. This ensures firmware-level compatibility, reliable performance, and support from Lenovo's technical teams.

Q: Does this memory module support ECC?
A: Yes. The 4X77A12186 includes ECC (Error Correcting Code) support, which detects and corrects single-bit memory errors in real time, making it suitable for mission-critical and enterprise server environments where data integrity is paramount.

Q: What is the advantage of a Registered (RDIMM) design over standard UDIMMs?
A: Registered DIMMs include a register buffer between the memory controller and DRAM chips, which improves signal integrity and allows more DIMMs to be installed per server without degrading stability — essential for high-capacity, multi-DIMM server configurations.

Q: Can I mix this module with other capacity or speed DIMMs in my server?
A: Mixing DIMMs of different capacities or speeds is generally not recommended as it may cause the system to downclock all modules to the lowest supported speed or cause instability. Lenovo recommends populating servers with matched DIMMs in supported configurations.

Q: Can I purchase the Lenovo 4X77A12186 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware specialist stocking genuine Lenovo ThinkSystem memory modules including the 4X77A12186. Contact our team for pricing, availability, and volume purchasing enquiries.
