8GB DDR3L 1333 ECC RDIMM for servers

This 8GB DDR3L registered DIMM delivers error-correcting memory for server and workstation platforms that require ECC RDIMM modules. It operates at 1333 MHz with CL9 latency and a low 1.35V voltage. The single-rank 1Rx4 organisation uses major-brand chips on a 240-pin DIMM form factor.

DDR3L 1333 registered ECC limits

The DDR3L 1333 standard caps data-rate at 1333 MT/s and requires a memory controller that supports registered ECC operation at 1.35V. Systems limited to unbuffered non-ECC DIMMs or to higher-voltage DDR3 1.5V will not accept this module. Maximum capacity per channel depends on the platform's memory controller and qualified-vendor list.

Check system memory specifications before ordering

Verify that your server or workstation lists DDR3L 1333 ECC RDIMM 1Rx4 modules on its qualified-vendor list or hardware maintenance manual. Confirm the motherboard provides 240-pin DIMM slots wired for registered ECC at 1.35V and that the BIOS revision supports this density and rank configuration. Matching the original IBM-Lenovo part numbers 46C0556, 00D4981 or 46C0580 is a strong compatibility indicator.

Questions about this item

Should I pick the 1Rx4 version or a different rank for my server?

The 1Rx4 organisation puts all 8 GB on a single rank, so the memory controller sees one logical rank per module and you can populate more slots before hitting the platform rank limit.

What does DDR3L 1333 actually deliver inside a running system?

The module runs at 1333 MT/s with CL9 timing at 1.35 V, giving registered ECC bandwidth that matches the PC3L-10600 rating for server workloads.

Is the 240-pin DDR3L interface compatible with standard DDR3 slots?

The 240-pin DDR3L DIMM fits physically into DDR3 sockets, but the CPU and chipset must support 1.35 V operation; otherwise the module will not function correctly.
