Target System Upgrade

This 4GB DDR3 1333MHz ECC RDIMM serves as a compatible replacement for IBM-Lenovo part 44T1586. It is built for server and workstation platforms that require registered error-correcting memory. The module fits 240-pin DIMM slots and runs at standard 1.5V voltage. Buyers needing higher density per slot or non-ECC memory for desktop boards will not find a match here.

Sustained Workload Behaviour

Registered buffering and ECC logic maintain data integrity during continuous operation in multi-socket environments. CL9 latency at PC3-10600 speed delivers predictable throughput for virtualisation hosts and database servers. The 2Rx8 organisation supports stable signalling across filled channels. Systems that demand higher frequency or lower latency than DDR3 1333 provides will need a different memory class.

Build And Connector Practicalities

Major-brand chipset components undergo quality assurance testing before shipment. The 240-pin DDR3 form factor aligns with standard server DIMM sockets, so installation follows normal procedures. Registered design adds a clock cycle, which the memory controller must support. Platforms limited to unbuffered DIMMs or newer DDR generations cannot accept this module.

Questions about this item

What power draw should I expect from this 1.5V DDR3 RDIMM when the server runs continuously?

The module operates at the standard DDR3 voltage of 1.5V; actual power consumption depends on the server platform and workload.

Does my system need a registered DIMM slot to accept this 240-pin ECC module?

Yes, this is a registered (RDIMM) 240-pin DDR3 module and requires a motherboard that supports registered ECC memory.

Will this CL9 1333MHz stick work alongside slower DDR3 RDIMMs already installed?

The module runs at DDR3 1333MHz CL9; the system will clock all installed RDIMMs to the speed of the slowest module.
