Speed DDR3L 1066 (PC3L 8500)

  • 32 GB quad-channel kit scales server memory capacity
  • 1066 MHz DDR3L speed accelerates data throughput
  • CL7 CAS latency sharpens response times
  • ECC registered design protects data integrity
  • 35 V low-voltage operation reduces power draw

Server DDR3L ECC RDIMM kit

This 32 GB kit contains four 8 GB registered DDR3L modules that run at 1066 MHz with a CAS latency of CL7. Each stick is a 4Rx8 quad-rank DIMM operating at 1.35 V and fitted with ECC for error correction. The 240-pin form factor is keyed for server and workstation platforms that require registered memory.

Suited for registered DDR3L platforms only

Administrators expanding memory in servers or workstations that specifically support quad-rank registered DDR3L DIMMs will find this kit compatible. Systems that require unbuffered modules, non-ECC memory, or a different rank configuration cannot use these sticks.

Quad-rank 4Rx8 organisation

The 4Rx8 quad-rank layout is the single specification that determines whether the motherboard’s memory controller can address the modules. Verify that your system’s qualified-vendor list accepts 4Rx8 registered DDR3L at 1066 MHz before ordering.

Questions about this item

Should I choose the 32GB quad-channel kit or buy single 8GB modules instead?

The 32GB kit contains four matched 8GB modules tested together for quad-channel operation on DDR3/DDR3L 1066 platforms, avoiding timing mismatches that can occur when mixing individual sticks.

What does the 1066 MHz rating actually deliver inside a registered ECC server?

At 1066 MHz with CL7 latency, each module transfers data at the PC3L-8500 rate while the registered buffer and ECC logic maintain signal integrity and error correction under sustained multi-threaded workloads.

How does the DDR3L 1.35V specification affect compatibility with 1.5V DDR3 slots?

These modules are dual-voltage rated at 1.35V and 1.5V, so they will operate at the lower DDR3L voltage when the platform supports it and fall back to standard DDR3 1.5V otherwise, using the same 240-pin registered DIMM interface.
