4GB DDR3 1600 ECC UDIMM Server Module

This 4GB DDR3 1600 ECC UDIMM module uses a 2Rx8 organisation and runs at 1.5V with CL11 latency. It is built for servers and workstations that require error-correcting unbuffered memory. The 240-pin DIMM replaces specific Hynix part numbers including HMT351E7CFR8C-PB and HMT351U7CFR8C-PB.

Sustained-load behaviour with ECC UDIMM

Error-correcting code detects and corrects single-bit errors during continuous operation, helping maintain data integrity under prolonged workloads. Unbuffered topology keeps latency low for typical server and workstation tasks. The module operates at standard DDR3 1.5V without additional cooling requirements.

Compatibility checks before ordering

Verify that your system accepts DDR3 1600 ECC UDIMM modules in a 2Rx8 configuration at 1.5V. Confirm the motherboard supports unbuffered ECC rather than registered or non-ECC memory. Check the number of available 240-pin slots and the maximum capacity per slot allowed by your platform.

Questions sur cet article

How much heat and power does the 1.5 V DDR3 1600 module draw when a server runs it continuously?

At the standard 1.5 V the module stays within normal DDR3 thermal limits, so a typical server chassis with adequate airflow keeps temperatures stable during all-day workloads.

What must the system already provide for this 240-pin ECC UDIMM to function?

The motherboard needs a DDR3 DIMM slot that accepts unbuffered ECC memory and a BIOS that supports 2Rx8 modules at 1600 MHz.

Will this 4 GB DDR3 stick work alongside older DDR3 modules already installed in my server?

Yes, provided the existing modules are also DDR3 ECC UDIMM running at 1.5 V; the system will clock all sticks to the lowest common speed and timing.
