Lenovo ThinkSystem 32GB DDR4-3200 ECC UDIMM

Unbuffered memory is the notable thing about the Lenovo ThinkSystem 4X77A77496. It is a 32GB ECC UDIMM, 2Rx8, running DDR4-3200 at 1.2V with a CAS latency of 22. The 2Rx8 layout means two ranks of x8 chips on the module.

UDIMMs are found in entry-level servers and workstation-class platforms rather than in large registered-memory builds, and they cannot be mixed with RDIMMs.

The ECC support means single-bit errors are corrected, which matters on any server that stays up for long periods.

This part is offered in all three conditions. New and refurbished units carry 1 year or 3 years of warranty, and used units carry 90 days. Tell us your server model and how many modules you need and we will reply with pricing and availability.
