Lenovo System-Specific DDR4 Upgrade

The Axiom 4X70F28590-AX is a 16GB DDR4 module built for Lenovo systems. It operates at 2133 MT/s with CL15 latency and runs at 1.20V. The registered ECC design targets servers and workstations that require error correction and signal buffering for stable operation.

288-Pin Registered ECC Integration

This 288-pin DIMM plugs directly into compatible Lenovo DDR4 slots. Registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel. ECC functionality corrects single-bit errors to protect data integrity in critical workloads.

DDR3 to DDR4 Capacity Jump

The module replaces DDR3 memory by delivering 100% faster data rates and up to 300% higher densities. A 20% reduction in power demand lowers cooling requirements. The upgrade is worthwhile when ECC registered support and 16GB per slot are needed for enterprise applications.

Questions about this item

What speed and latency limits does the DDR4 2133 CL15 module hit under sustained workloads?

The module runs at DDR4 2133 (PC4 17000) with CAS latency 15, so sustained throughput and response time are capped by those rated figures.

How much heat and power does the 1.20 V registered DIMM produce during all-day operation?

At 1.20 V the registered DIMM draws 20 % less power than DDR3, reducing both heat output and cooling demand during continuous use.

Which Lenovo systems accept this 288-pin ECC registered stick?

The stick is validated for Lenovo platforms that support 288-pin DDR4 ECC registered memory; check your system’s qualified-vendor list for exact model confirmation.
