Server memory upgrade

This 64GB kit contains four 16GB DDR3 1333 registered ECC modules built for Lenovo System x3550 M3 x3620 M3 x3630 M3 x3650 M3 and x3850 X5 servers. The 240-pin RDIMMs run at 1.5V with CL9 latency and 2Rx4 organisation. They replace Lenovo part numbers 03X3813 and 0A89413.

Sustained workload behaviour

ECC registered design corrects single-bit errors and buffers address and command signals so the memory controller stays stable during long compute runs. The modules are JEDEC and RoHS compliant and tested in-house for multi-hour operation without throttling.

Registered ECC requirement

This kit only works in systems that require registered ECC DDR3 RDIMMs; it will not function in desktops or workstations that take unbuffered non-ECC memory and it cannot be mixed with unbuffered modules.

Perguntas sobre este artigo

How much power does the 1.5V DDR3 1333 kit draw when the server runs continuously?

Each module operates at 1.5V; total consumption depends on the server's memory controller and workload, not on the kit alone.

What must the Lenovo System x3550 M3 already have to accept these 240-pin RDIMMs?

The server must support DDR3 ECC Registered memory and provide 240-pin DIMM slots; unbuffered DIMMs cannot be mixed with this kit.

Can I keep the existing 03X3813 modules and add this 64GB kit alongside them?

All DIMMs should match in capacity, speed and manufacturer for optimal performance; mixing different modules is not recommended.
