A-Tech 4GB DDR3 1866 ECC RDIMM

This A-Tech module is a 4GB DDR3 1866MHz registered DIMM with ECC and a 2Rx8 organisation. It operates at the standard 1.5V and carries a CL13 latency rating. The 240-pin form factor fits server and workstation boards that require registered memory.

Suited for servers needing registered ECC modules

The registered design and ECC function make this module appropriate for platforms that require buffered, error-correcting memory. Systems that accept only unbuffered UDIMMs or that are limited to single-rank configurations will not support this 2Rx8 registered DIMM.

Registered ECC with 2Rx8 organisation

The combination of registered signalling, ECC capability and a dual-rank 2Rx8 layout is the specification that determines whether this module will work in a given server. Verify that the system board explicitly supports registered ECC DDR3 DIMMs with this rank configuration before purchasing.

Questions sur cet article

Does my motherboard need a 240-pin DDR3 slot that supports 1.5 V registered ECC modules?

Yes — this module is a 240-pin DDR3 DIMM that runs at 1.5 V and requires a slot wired for registered ECC operation.

If I add this 1866 MHz stick to slower DDR3 modules, what speed will the system run at?

The memory controller will clock all installed modules down to the lowest common speed, so this 1866 MHz stick will run at the speed of the slowest module present.

How can I confirm the module is detected as 4 GB ECC registered at 1866 MHz with CL13 timings?

Check the BIOS memory summary or run a tool such as CPU-Z; it should show 4 GB, ECC registered, 1866 MHz (PC3-14900) and CAS latency 13.
