Speed DDR3L 1600 (PC3L 12800)

  • 32 GB total capacity across eight 4 GB modules
  • DDR3L 1600 MHz speed with CL11 latency for responsive operation
  • ECC unbuffered design detects and corrects data errors
  • Low-voltage 1.35 V operation reduces power draw and heat
  • Dual-rank 2Rx8 organisation on 240-pin DIMMs for server compatibility

32 GB ECC UDIMM kit for servers and workstations

This A-Tech kit supplies 32 GB of DDR3L 1600 memory across eight 4 GB modules. Each module is an unbuffered ECC UDIMM with a 2Rx8 dual-rank organisation. The kit is built for servers and workstations that require error-correcting memory. It is not compatible with desktop or laptop computers.

240-pin DDR3L slots at 1.35 V with CL11 timing

The modules fit 240-pin DDR3/DDR3L DIMM slots and operate at 1.35 V, with support for 1.5 V where the platform requires it. CAS latency is CL11 at 1600 MHz. The unbuffered design connects directly to the memory controller without a register. Verify your system manual for supported memory specifications, channel population rules and seating order before installation.

Eight modules fill eight slots for 32 GB total

The eight 4 GB modules populate eight DIMM slots to reach the 32 GB kit capacity. This configuration suits workloads that benefit from ECC protection and multiple memory channels. Systems with fewer than eight slots or a lower maximum capacity per slot cannot use the full kit. Buyers who need higher densities per module or registered memory should select a different product.

Questions about this item

Will the CL11 latency at 1600 MHz hold under continuous server workloads?

The modules run at DDR3L 1600 with a fixed CL11 timing, so latency remains consistent during sustained operation.

How much heat and power do eight 1.35 V DDR3L sticks produce in a 24/7 rack?

Each DIMM operates at 1.35 V low voltage, reducing both power draw and thermal output compared to standard 1.5 V DDR3.

My motherboard has 240-pin DDR3 slots — is that all I need for this ECC UDIMM kit?

You need a server or workstation board that supports DDR3 ECC unbuffered memory; desktop and laptop platforms will not work.
