A-Tech 4GB DDR3 1333MHz ECC RDIMM 2Rx8 Server Memory 44T1586

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.
