Server Memory Upgrade

This A-Tech 4GB DDR3 module runs at 1066MHz with PC3-8500 bandwidth and CL7 latency. It is a registered ECC DIMM built for server and workstation platforms that require error correction and signal buffering. The 240-pin form factor operates at standard 1.5V DDR3 voltage.

Compatibility Profile

Suits administrators expanding capacity in systems validated for DDR3 registered ECC memory with 4Rx8 organisation. Not suited for desktop boards that accept only unbuffered non-ECC modules or for platforms limited to lower-rank configurations. Verify your system's qualified vendor list before ordering.

What the Bundle Changes

The package contains a single qualified memory module tested to Micron MT36JSZF51272PDZ-1GF1D equivalence. No cables, brackets or software are included; the upgrade effect comes entirely from adding registered ECC capacity to a compatible motherboard.

Questions about this item

My server only has DDR3 slots — will this 240-pin ECC RDIMM fit and run at 1066 MHz?

Yes, the module is a 240-pin DDR3 DIMM rated for 1066 MHz PC3-8500, so it installs directly into any DDR3 server slot that accepts registered ECC memory.

Can I mix this 4Rx8 registered stick with the older 2Rx4 unbuffered modules already in my system?

No, registered and unbuffered DIMMs cannot be used together; the memory controller will not initialise a mixed configuration.

After installing the module, how can I confirm it is running at the rated 1066 MHz with ECC active?

Check the BIOS memory information or run a tool such as CPU-Z; it should report 1066 MHz, CL7 timings, 1.50 V and ECC enabled.
