  • Buffered/RegisteredRegistered
  • 8GB capacity expands server memory for heavier workloads
  • DDR3L 1066MHz speed matches PC3-8500 system requirements
  • ECC registered design detects and corrects data errors
  • 35V low voltage reduces power draw and heat
  • 240-pin DIMM form factor fits standard DDR3 server slots

Server DDR3L RDIMM module

This 8 GB registered DIMM runs at 1066 MHz with a CAS latency of CL3 and operates at 1.35 V. It uses a 4Rx8 organisation built on Samsung chipset and carries ECC for error correction in server workloads.

Compatibility checklist

Verify that your motherboard accepts DDR3L RDIMM modules at PC3-8500 speed and supports 4Rx8 registered memory. Confirm the system can address an 8 GB module in the target slot and that the BIOS recognises registered ECC DIMMs.

Build and connectors

The module uses a 240-pin DIMM edge connector despite the 262-pin form-factor reference in the data sheet. Low-voltage 1.35 V operation reduces heat output in dense server chassis. Registered buffering adds one clock cycle of latency but improves signal integrity on heavily populated memory buses.

Questions about this item

Does the box contain only the single 8GB DDR3L 1066 ECC RDIMM or are any cables or brackets included?

The package includes one 8GB DDR3L 1066MHz PC3L-8500 ECC Registered DIMM module; no cables, brackets or additional hardware are supplied.

Should I choose this 4Rx8 registered module or look for a different rank configuration for my server?

Select this 4Rx8 registered ECC module if your server requires DDR3L 1066 registered memory with that rank organisation; otherwise verify the platform’s qualified vendor list for supported rank and voltage combinations.

What does the 1066MHz PC3L-8500 rating mean for actual throughput once the module is installed?

The module transfers data at 1066 MT/s, delivering a peak bandwidth of 8500 MB/s per channel when the memory controller runs at the rated DDR3L 1066 speed.
