16GB DDR3L ECC RDIMM for Dell servers

This 16GB DDR3L registered DIMM runs at 1066MHz with CL7 latency and 1.35V operation. It uses a 4Rx4 organisation and major-brand chips to deliver error-correcting memory for compatible Dell PowerEdge systems.

240-pin registered build with low-voltage chips

The module follows the standard DDR3 DIMM 240-pin form factor and carries ECC registered buffering for signal integrity in multi-DIMM configurations. Low-voltage DDR3L chips reduce power draw and heat output compared with standard 1.5V DDR3, helping dense server chassis stay within thermal limits.

Check DDR3L 1066 support

Verify that your server accepts DDR3L at 1066MHz, supports registered ECC DIMMs, and can address 4Rx4 modules at the desired capacity per slot. Cross-reference the Dell part numbers A5276601, A5095849, A5095850, A5180152, A5180241 and A5180243 against your system's qualified-vendor list to confirm compatibility.

Questions about this item

What speed does the DDR3L 1066 PC3L-8500 rating actually deliver in a registered DIMM?

The module operates at DDR3L 1066 MHz with a PC3L-8500 rating and CL7 latency, providing the standard data rate for registered DDR3L server memory.

Will this 240-pin 4Rx4 RDIMM fit my Dell server that uses the A5276601 or A5095849 part numbers?

Yes, the 240-pin DDR3L form factor matches the Dell A5276601, A5095849, A5095850, A5180152, A5180241, and A5180243 part numbers for direct replacement.

What is the correct way to seat this 1.35V registered ECC module, and what step is often missed?

Align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then verify the system recognises the full 16 GB capacity and ECC function in BIOS or the OS.
