A-Tech 4GB DDR3 ECC UDIMM Server Memory

This A-Tech module provides 4GB of DDR3 1866 ECC unbuffered memory for compatible server and workstation systems. It operates at standard 1.50V with CL13 latency and uses a 1Rx8 configuration on a 240-pin DIMM form factor.

Replaces HP 733036-581 and E2Q91AA part numbers

The module serves as a direct equivalent for HP part numbers 733036-581 and E2Q91AA. The upgrade is worthwhile when your system requires ECC UDIMM memory at DDR3 1866 speed and has available DIMM slots for capacity expansion.

Verify your system supports DDR3 1866 ECC UDIMM

Check that your motherboard accepts unbuffered ECC DDR3 memory at this speed and rank configuration before ordering. Consult your system documentation for supported memory specifications and maximum capacity limits per slot.
