Installation is straightforward for anyone familiar with server memory, and A-Tech backs the modules with a lifetime warranty and toll-free support for added peace of mind.

Key Features

• Capacity and configuration: The kit includes two 16GB modules to provide a total of 32GB of memory in a matched pair for dual-channel server use.
• Memory type: These are ECC Registered RDIMM modules, which help maintain data integrity on supported servers and are intended for server-class workloads.
• Speed and form factor: Modules are DDR4 PC4-21300 at 2666MHz in 288-pin DIMM format, fitting the physical and speed expectations of the ThinkServer RD450 platform.
• Voltage and rank: Operates at 1.2v and uses a 1Rx4 rank organization, aligning with server motherboard requirements when supported.
• Compatibility cue: Marketed as designed for Lenovo ThinkServer RD450 and listed as equivalent to IBM/Lenovo part 7X77A01302, easing part selection for replacement or expansion.

Who It's For

The kit is best for IT administrators, small datacenter operators, and professionals running Lenovo ThinkServer RD450 systems who need a matched, error-correcting memory solution for stable server operation. It is also a good fit for users who prefer a non-OEM alternative but need the equivalent to part 7X77A01302.

It is not intended for desktop systems or laptops, and it will not function correctly in machines that require unbuffered or non-ECC memory. Buyers should verify CPU and motherboard support for ECC registered modules before purchasing, since all memory in the system must be the same ECC type.

Pros & Cons
