Capacity and form factor

This A-Tech module provides 16GB of DDR3 server memory in a 240-pin RDIMM form factor. It operates at 1066MHz with a PC3-8500 rating and a CAS latency of CL7. The stick runs at the standard 1.50V DDR3 voltage and uses a 4Rx8 rank configuration with major-brand chips.

Compatibility fit

The module is built as a direct replacement for the IBM-Lenovo 77P8692 part number and targets servers or workstations that require registered ECC memory. Systems that only accept unbuffered non-ECC DIMMs or that use a different DDR generation will not support this stick. Buyers should verify their platform's qualified-vendor list before ordering.

Decisive specification

Registered ECC operation is the single attribute that determines whether this DIMM will work in a given chassis. If the motherboard demands registered error-correcting modules, this 16GB kit meets that requirement; otherwise the system will not post.

Questions about this item

How do I install this 240-pin DDR3 RDIMM, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin DDR3 module with the slot key, press firmly until both retention clips click, then verify the BIOS recognises the full 16 GB at 1066 MHz.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; the module either passes POST and runs indefinitely or it fails, at which point you replace the single 16 GB stick with another DDR3 1066 ECC RDIMM.

What limit appears first when this 4Rx8 module runs under sustained load?

The four-rank organisation increases electrical loading on the memory bus, so the platform’s maximum supported rank-per-channel limit is reached before bandwidth or thermal limits become an issue.
