A-Tech 4GB DDR3L 1333 ECC UDIMM

This module is a 4GB DDR3L server memory stick built for systems that require ECC unbuffered DIMMs. It suits administrators upgrading compatible workstations or servers where data integrity matters. The 240-pin form factor fits standard DDR3 DIMM slots in supported platforms.

PC3L-10600 speed with CL9 latency

The decisive specification is the DDR3L 1333 speed rated as PC3L-10600 with CAS latency CL9. Your motherboard and processor must support this exact speed grade and voltage for the module to operate correctly. Verify the system documentation before purchase.

Low-voltage operation at 1.35V

Running at 1.35V reduces power draw and heat output compared to standard 1.5V DDR3 modules. The unbuffered ECC design adds minimal overhead while maintaining signal integrity. Typical server workloads see stable thermals without extra cooling requirements.

Questions about this item

What does the 1333 speed rating mean for actual throughput in a server?

The module operates at DDR3L 1333 MT/s with CL9 latency, delivering the standard data rate for PC3L-10600 when installed in a compatible platform.

How does the DDR3L 1.35 V standard affect power use and compatibility?

DDR3L runs at 1.35 V, reducing power draw versus 1.5 V DDR3; it will operate at 1.35 V in systems that support the low-voltage spec and at 1.5 V in standard DDR3 slots.

What physical slot and clearance does the 240-pin UDIMM need?

It fits a standard 240-pin DDR3 DIMM socket and uses the unbuffered UDIMM form factor, so ensure the board has an unbuffered slot and enough height clearance for the module.
