4GB DDR3 ECC UDIMM for Servers

This 4GB DDR3 1066MHz PC3-8500 ECC UDIMM module uses a 2Rx8 unbuffered design with major brand chips. It operates at standard 1.5V voltage with CL7 latency. The 240-pin DIMM is built as a compatible equivalent for Hynix HMT351U7AFR8C-G7 and HMT351U7BFR8C-G7 modules. It targets administrators upgrading DDR3 server or workstation platforms that require error-correcting memory.

Thermals and Power at Standard Voltage

Running at the JEDEC standard 1.50V, the module draws typical DDR3 power without elevated voltage overhead. The unbuffered layout avoids the extra register components that increase consumption on registered DIMMs. No active cooling is included or specified, so airflow within the server chassis handles heat dissipation during normal multi-tasking workloads.

Quality Assurance and Support Inclusions

Every module undergoes quality assurance testing before shipment to verify reliable operation. The purchase includes a lifetime warranty against defects and access to United States-based technical support for compatibility questions before and after installation. No additional software, heat spreaders or mounting hardware are bundled with the memory stick.

Vragen over dit artikel

How do I install this 240-pin DDR3 UDIMM and what step do people often miss?

Align the notch on the module with the key in the 240-pin slot, press firmly until both side clips click shut, then verify in BIOS that the server detects 4 GB at 1066 MHz with ECC active.

What maintenance or replacement will this ECC UDIMM need over time?

No routine maintenance is required; if a correctable error count climbs or the module fails POST, replace it with another DDR3 1066 ECC UDIMM of matching voltage and rank.

What limit appears first when this 1.5 V module runs under sustained load?

The DDR3 1066 (PC3-8500) bandwidth ceiling is reached before thermal throttling, so sustained throughput tops out at the rated 8500 MT/s transfer rate.
