DDR3L ECC UDIMM kit for servers

This A-Tech kit provides 8 GB of DDR3L 1600 ECC unbuffered memory in a matched pair of 4 GB modules. It is built for servers and workstations that require error-correcting code support and dual-channel operation. The modules run at 1.35 V low voltage and carry a CL11 latency rating. Desktop and laptop systems cannot use this memory.

DDR3L 1600 speed and voltage limits

The DDR3L standard tops out at 1600 MT/s and 1.35 V, so this kit runs at the highest JEDEC speed for the technology. Systems limited to 1.5 V DDR3 can still use the modules because they are backward compatible to that voltage. No higher DDR3L frequencies or lower voltages exist within the specification.

ECC unbuffered requirement decides fit

The single specification that determines compatibility is the need for ECC unbuffered DDR3L DIMMs in a 240-pin form factor. If your server or workstation manual calls for registered, fully buffered or non-ECC memory, this kit will not work. Buyers who need registered ECC or standard desktop memory must choose a different module type.

Questions about this item

Should I choose this dual-channel 8 GB kit or a single 8 GB module for my server?

This kit provides two matched 4 GB modules for dual-channel operation, which doubles memory bandwidth compared to a single 8 GB stick on platforms that support it.

What does the 1600 MHz rating deliver in an actual server workload?

At 1600 MHz with CL11 timing, the modules move data at up to 12 800 MB/s per channel, reducing latency for database and virtualization tasks.

Is the PC3L-12800E interface limited to 1.35 V only?

The DDR3L modules run at 1.35 V but are also rated for 1.5 V, so they work in both low-voltage and standard DDR3 slots.
