  • 32 GB kit expands server capacity for heavier workloads
  • DDR3 1866 MHz speed accelerates data throughput
  • ECC unbuffered design corrects single-bit errors automatically
  • CL13 latency at 1.5 V balances responsiveness and stability
  • 8 × 4 GB single-rank modules populate 240-pin DIMM slots

Server Memory Kit

The A-Tech 32GB kit contains eight 4GB DDR3 1866 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. It delivers 32GB total capacity across 240-pin DIMM slots running at 1.5V standard voltage.

DDR3 Platform Limit

DDR3 1866 represents the upper mainstream speed for this generation so bandwidth is capped by the memory controller in your server or workstation. The CL13 latency and single-rank 1Rx8 organisation are fixed by the module design and cannot be altered.

Build and Connectors

Each module uses major-brand chips tested to A-Tech quality standards and carries a lifetime warranty with US-based technical support. The 240-pin UDIMM form factor fits only DDR3 ECC unbuffered slots so it will not work in desktop or laptop systems.

Questions about this item

Should I choose this 32GB kit or a smaller capacity kit?

This kit provides 32GB total across eight 4GB modules; select the capacity that matches your server's maximum supported memory and the number of available DIMM slots.

What does the 1866 MHz speed mean for actual server performance?

The modules run at DDR3 1866 (PC3-14900) with CL13 latency, delivering the rated throughput when the platform's memory controller operates at that frequency.

How does the PC3-14900E designation affect compatibility?

PC3-14900E identifies DDR3 1866 ECC unbuffered DIMMs; the kit uses 240-pin 1.5V 1Rx8 modules that fit only systems specifying DDR3 ECC UDIMM support.
