Server DDR3 ECC RDIMM

This A-Tech module adds 4GB of registered ECC memory to compatible servers and workstations. It uses a 240-pin DDR3 DIMM form factor and is built as a direct replacement for the Samsung M393B5273BH1-CF8 part. The 2Rx8 organisation and major-brand chips are intended for systems that require error correction and registered buffering.

DDR3 1066 practical limits

DDR3 1066 (PC3-8500) tops out at 1066 MT/s with a standard 1.5V supply, so bandwidth is capped at the PC3-8500 level. Registered signalling adds one clock cycle of latency, and the platform's memory controller determines the maximum usable capacity and populated slot count. Mixing speeds will force all modules to run at the lowest common rate.

Registered ECC requirement

The module is an ECC RDIMM, so it only works in systems whose chipset and BIOS explicitly support registered error-correcting memory. Desktop or consumer boards that accept only unbuffered non-ECC DIMMs will not recognise it. Verify the platform's qualified-vendor list before purchase.

Preguntas sobre este artículo

Should I choose the 4GB DDR3 1066MHz ECC RDIMM or a different capacity for my server?

This module provides 4GB in a single 240-pin DDR3 ECC RDIMM running at 1066MHz. Select it when your system requires registered ECC memory at that speed and you need a 4GB increment.

What does PC3-8500 mean for real-world throughput in my machine?

PC3-8500 is the JEDEC designation for DDR3 1066MHz memory. Your actual throughput depends on the platform's memory controller and how many channels it populates.

Does the 240-pin DDR3 interface limit the 1066MHz speed in practice?

The 240-pin DDR3 form factor carries the 1066MHz signal. The registered buffer and ECC logic operate at that frequency, so the interface itself does not impose a lower cap.
