4GB DDR3L 1600 ECC RDIMM 1Rx4 server memory

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V low voltage. It uses a registered DIMM design with ECC for error correction and a single-rank 1Rx4 organisation on a 240-pin form factor.

Suits servers and workstations needing registered

Builders whose platforms require unbuffered non-ECC modules or a different voltage cannot use this part. Systems that only accept higher-capacity registered DIMMs will also need to look elsewhere.

Registered ECC with 1Rx4 organisation

The registered buffer and ECC function together with the single-rank 1Rx4 layout decide compatibility; the motherboard must support registered ECC DDR3L DIMMs in this configuration.

Questions about this item

What comes in the box and do I need to buy anything else to install it?

The box contains one 4 GB DDR3L 1600 ECC RDIMM module with a 240-pin DIMM form factor. No additional parts are required for installation in a compatible server or workstation.

How do I decide between the Samsung M393B5270CH0-YK0, M393B5270DH0-YK0, M393B5270EB0-YK0 and M393B5270QB0-YK0 equivalents?

All four Samsung part numbers share the same 4 GB capacity, 1Rx4 organisation, 1.35 V DDR3L 1600 speed and ECC RDIMM registration. The A-Tech module replaces any of them interchangeably.

What does the 1600 MHz PC3L-12800 rating mean once the module is running in my server?

The module operates at 1600 MHz with a peak transfer rate of 12800 MB/s at CL11 latency, delivering low-voltage ECC registered performance for stable server workloads.
