A-Tech 8GB DDR3 1066MHz ECC RDIMM 4Rx8 Server Memory 46C7504 43X5276

A-Tech 8GB DDR3 1066MHz ECC RDIMM

This 8GB registered DIMM is built for servers and workstations that require error-correcting memory. It operates at DDR3 1066 (PC3-8500) with a CAS latency of CL3 and a standard 1.50V supply. The module uses a 4Rx8 rank organisation and major-brand chips. It is a compatible replacement for IBM-Lenovo part numbers 46C7504 and 43X5276.

Registered DIMM for 240-pin DDR3 slots

The module fits 240-pin DDR3 DIMM sockets and presents a registered signal to the memory controller, reducing electrical load on the bus. ECC capability detects and corrects single-bit errors, which protects data integrity in multi-socket or virtualised workloads. Systems must support registered ECC DDR3 memory; consumer boards that accept only unbuffered non-ECC DIMMs cannot use this module.

8GB capacity with 4Rx8 organisation

The single 8GB stick adds substantial capacity for virtualisation hosts, database buffers or large-file caching. The quad-rank 4Rx8 layout maximises density per slot, though some platforms limit the number of registered ranks per channel. Buyers who need higher total memory should verify their system's maximum supported rank count and slot population rules before adding multiple modules.
