A-Tech 8GB DDR3 1066MHz ECC RDIMM 2Rx4 Server Memory 44T1580 43X5303

SKU CH-QGFQ-226A1

An 8 GB DDR3 registered ECC server module running at 1066 MHz with CL3 latency and 1.5 V operation

  • Capacity8GB
  • SpeedDDR3 1066 (PC3 8500)
  • CAS LatencyCL3
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 8GB capacity expands server memory headroom for heavier workloads
  • DDR3 1066MHz PC3-8500 speed matches system bus requirements
  • ECC registered design detects and corrects single-bit errors automatically
  • 2Rx4 dual-rank organisation maximises density per DIMM slot
  • 5V standard DDR3 voltage ensures broad platform compatibility

Compatible DDR3 ECC RDIMM Upgrade

This 8 GB registered DIMM runs at DDR3 1066 (PC3-8500) with CL3 latency and 1.50 V operation. It is built as a direct replacement for IBM-Lenovo part numbers 44T1580 and 43X5303 and uses a 240-pin form factor with 2Rx4 organisation.

Suited for servers needing registered ECC memory

The module fits systems that require DDR3 registered ECC RDIMMs and accept the listed IBM-Lenovo part numbers. It is not suitable for platforms that only support unbuffered UDIMMs, non-ECC memory, or a different DDR generation.

Registered ECC with 2Rx4 organisation

The single specification that decides compatibility is the registered ECC RDIMM design with 2Rx4 rank configuration. Verify that your server’s memory controller and BIOS support this exact arrangement before purchase.

Questions about this item

Will the registered ECC design of this 8 GB DDR3 1066 MHz module require any periodic maintenance or replacement?

No routine maintenance is needed for the registered ECC DIMM; it runs at the standard 1.5 V and will only require replacement if a memory error occurs or a capacity upgrade is desired.

What is the first limit reached under sustained load with this CL3 1066 MHz registered DIMM?

The DDR3 1066 MHz PC3-8500 data rate and CL3 latency set the throughput ceiling before any thermal or power limit is reached.

How much heat and power does this 1.5 V DDR3 RDIMM produce when running continuously?

Operating at the standard 1.5 V DDR3 voltage, the module draws typical DDR3 power and generates modest heat that is handled by normal server airflow.
