Memory Module HPE DDR3 4GB 1333MHz ECC
The HPE 647893-B21 Memory Module HPE DDR3 4GB 1333MHz ECC is a 4 GB DDR3 ECC DIMM designed for PCs and servers. It operates at a clock speed of 1333 MHz with CAS latency 9 and uses the 240-pin DIMM form factor. With a voltage rating of 1.35 V, this HPE Enterprise module is intended to provide stable error-correcting memory for systems that support ECC DIMMs and require reliable performance for multitasking and data-integrity-sensitive workloads.
ECC (Error-Correcting Code) memory helps detect and correct certain types of memory errors, increasing system reliability in server and workstation environments. The 1333 MHz DDR3 speed balances compatibility and performance for legacy platforms. The 240-pin DIMM design ensures compatibility with standard DDR3 memory sockets in supported motherboards. Low operating voltage of 1.35 V contributes to lower power consumption compared with higher-voltage modules while maintaining stable operation.
Power down the system and disconnect it from the mains before installing the DIMM. Open the case or server chassis according to the manufacturer's instructions. Locate the appropriate DDR3 240-pin ECC DIMM slot and release the retention clips. Align the notch on the module with the keyed slot and insert the module firmly until the clips latch. Reassemble the chassis, reconnect power, and power on the system. Confirm that the system BIOS/UEFI recognizes the new 4 GB ECC module and that ECC functionality is enabled if required by the platform.
Verify motherboard and server compatibility with DDR3 ECC 1333 MHz modules and check vendor support for mixed capacities or ranks before installing. For optimal reliability in multi-module configurations, install modules in matched pairs or following the server manufacturer's memory population guidelines. Use anti-static precautions during handling and consult system documentation for BIOS/UEFI settings related to ECC operation.
