  • Unbuffered non-ECC design suits standard server workloads

Axiom 8 GB DDR4 Server Memory

This Axiom module provides 8 GB of DDR4 memory for compatible servers and workstations. It uses a 288-pin DIMM form factor and operates at 1.2 V. The unbuffered, non-ECC design suits systems that do not require registered or error-correcting memory. It is built for reliable operation in supported Lenovo platforms.

Who this suits and who should look elsewhere

This memory fits administrators upgrading a Lenovo S510, ThinkCentre M700, M800, M900 or ThinkStation P310 that accepts unbuffered non-ECC DDR4 DIMMs. It also serves general-purpose server tasks at 2133 MHz with CL15 latency. Buyers who need ECC protection for data integrity or registered modules for higher-density configurations should look elsewhere.

Deciding specification: PC4-17000 speed rating

The module runs at DDR4-2133, also designated PC4-17000, with a CL15 latency. This speed rating determines whether the part matches the system’s memory bus and timing requirements. Verify the platform’s qualified-vendor list for this exact frequency and latency before purchase.
