Lenovo 8GB DDR3-1600 ECC RDIMM 90Y3109 | Server Memory, DIMM

Keep legacy IBM System x environments running with memory designed for predictable server operation. This Lenovo 8 GB RDIMM delivers DDR3-1600 performance, ECC error correction, and registered signaling to help preserve data integrity under sustained load. The 2Rx4 architecture and CL11 timing support balanced responsiveness for virtualization hosts, application servers, and general-purpose infrastructure that still depends on DDR3 platforms. Built as a 240-pin DIMM at 1.5 V, this module fits systems that require PC3-12800 DDR3-1600 memory and registered ECC behavior. It is specified for IBM System x240 and System x3650 M4 (7915), making it a targeted replacement or expansion part for environments where compatibility matters more than generic capacity. For teams extending the life of installed hardware, the right server-grade module can reduce instability, simplify maintenance, and avoid the cost of premature platform refreshes. Choose this module when you need dependable capacity in a form factor that matches the server’s memory architecture. It is a practical fit for procurement teams standardizing on verified Lenovo sourcing for supported IBM servers.
