Server ECC RDIMM upgrade

This 16 GB DDR3L 1600 registered DIMM is built for Supermicro X9DRL, X9DRT, X9DRW, X9DRX+ and X9QR7 motherboards. It delivers ECC protection and registered buffering for workstation, server, NAS and router workloads. The module runs at 1.35 V with CL11 latency and a 2Rx4 organisation.

Replaces unbuffered or non-ECC modules

The jump is worth it when your platform requires registered ECC memory and cannot accept unbuffered DIMMs. Mixing registered with unbuffered memory is not supported, so a full set of matching modules is needed. Buyers who need standard desktop DDR3L without ECC or registration should choose a different product.

Fits 240-pin DDR3L slots

Installation uses the existing 240-pin DIMM sockets on the listed Supermicro boards. The low-voltage 1.35 V operation reduces power draw compared with 1.5 V DDR3. No heat spreader is included, so airflow in the chassis handles cooling. Ensure the system BIOS is current for full compatibility.

Questions about this item

Will the 240-pin DDR3L 1.35V module fit my Supermicro X9DRX+ motherboard DIMM slots?

Yes, the 240-pin DDR3L RDIMM is built for the X9DRX+ and the other listed X9 series boards, so it seats directly in the standard DDR3 DIMM slots.

What is the correct way to install this ECC Registered RDIMM so the server recognises the full 16GB?

Power down, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then power on and verify 16GB in BIOS.

When should I plan to replace this DDR3L 1600 CL11 RDIMM in a 24/7 server?

ECC Registered DDR3L modules typically run for years; replace only if memory tests report correctable errors rising or the system logs uncorrectable ECC events.
