4GB DDR3 1066 ECC RDIMM for Servers

This A-Tech module delivers 4GB of DDR3 1066 memory in a registered DIMM format with ECC support. It is built for servers and workstations that require registered, error-correcting memory to maintain data integrity under sustained workloads. The 2Rx8 organisation and CL7 latency suit compatible DDR3 platforms.

DDR3 1066 registered DIMM constraints

The DDR3 1066 standard caps the data rate at 1066 MT/s and requires a 1.5 V supply, which this module meets. Registered buffering adds a clock cycle of latency but reduces electrical load on the memory controller, allowing larger total capacities than unbuffered DIMMs. Systems must support PC3-8500 registered ECC DIMMs to use this part.

ECC registered requirement decides fit

This module will only function in platforms that explicitly accept DDR3 ECC RDIMMs; it will not work in desktop boards or laptops that require unbuffered non-ECC memory. Verify that your system lists PC3-8500 registered ECC support before purchasing. Buyers needing unbuffered or non-ECC memory should select a different module.

Questions about this item

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

This listing is a single 4GB module; add multiple identical sticks to reach the total capacity your server board supports.

What does the PC3-8500 rating mean for actual throughput in my server?

PC3-8500 denotes a peak transfer rate of 8500 MB/s at 1066 MHz; real-world bandwidth depends on the memory controller and channel configuration.

How does the 240-pin registered DIMM interface limit compatibility?

The 240-pin RDIMM fits only DDR3 server boards that accept registered ECC modules; it will not work in desktop UDIMM slots.
