Server-grade ECC RDIMM

This 8 GB DDR3L 1600 CL11 registered module is built for workstation and server boards that require error-correcting memory. It replaces Lenovo part numbers 00D5035, 00D5036, 46W0700 and 46W0771 in the System x3550 M3 R2. Standard desktop systems cannot use registered ECC DIMMs, so buyers needing ordinary PC memory should look elsewhere.

Verify registered ECC support

Before ordering, confirm your motherboard accepts 240-pin DDR3L registered ECC RDIMMs at 1.35 V and that it does not require unbuffered modules. Mixing registered and unbuffered DIMMs is not supported. Check the system manual for maximum capacity per slot and total population rules, as this module is a single 1Rx4 rank.

Low-voltage thermal profile

Operating at 1.35 V reduces power draw compared with standard DDR3, helping keep server chassis temperatures lower under load. The module has no heat spreader, so adequate airflow across the DIMM slots is required for stable operation. Registered buffering adds minimal latency while maintaining signal integrity in multi-DIMM configurations.

Perguntas sobre este artigo

Does the module ship as a single 8 GB stick or do I need to buy anything else to install it?

The upgrade consists of one 8 GB DDR3L 1600 CL11 1Rx4 ECC Registered RDIMM. No additional components are required for installation in a compatible slot.

Should I choose this 8 GB 1Rx4 registered module or a different capacity for my Lenovo System x3550 M3 R2?

This 8 GB 1Rx4 registered DIMM matches Lenovo part numbers 00D5035, 00D5036, 46W0700 and 46W0771. Select the capacity that fits your server's maximum memory configuration and available slots.

What does the 1600 MHz PC3L-12800 rating mean once the module is running in the server?

The module operates at DDR3L 1600 with CAS latency 11 at 1.35 V, delivering PC3L-12800 bandwidth when the system memory controller runs at that speed.
