DDR3L 1600MHz ECC Registered DIMM

This A-Tech 8GB DDR3L 1600MHz ECC RDIMM is a registered server memory module built for 240-pin DDR3 slots. It operates at 1.35V low voltage with CL11 latency and a 2Rx4 rank configuration using major brand chipsets.

Suited for Cisco UCS upgrades needing DDR3L ECC

This module matches the Cisco UCS-MR-1X082RY-A and 15-13637-02 part numbers for direct replacement in compatible systems. It is not suitable for platforms that require unbuffered UDIMM memory, non-ECC modules, or different DDR generations and pin counts.

240-pin DDR3L form factor decides fit

The module uses the 240-pin DDR3 DIMM form factor at 1.35V, so it only fits servers and workstations designed for DDR3L registered ECC memory. Verify your system documentation for this exact specification before purchase.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

Operating at 1.35V, this DDR3L RDIMM consumes less power than standard 1.5V DDR3, reducing heat output during 24/7 server workloads.

What motherboard slot and chipset support are required to install this 240-pin registered ECC DIMM?

You need a server or workstation board with a 240-pin DDR3 DIMM slot that accepts registered ECC memory and supports 2Rx4 organisation at 1600MHz.

Will this 2Rx4 CL11 module work alongside older 1Rx8 DDR3 sticks already in my Cisco UCS chassis?

Mixing 2Rx4 and 1Rx8 ranks is not guaranteed; the system may default to the slowest timing or disable the mismatched DIMMs, so verify the platform's qualified vendor list first.
