4GB DDR3 ECC UDIMM for Servers
This 4GB DDR3 1866MHz ECC unbuffered DIMM uses a 1Rx8 layout with CL13 latency at 1.5V. It targets administrators maintaining or expanding older server and workstation platforms that require DDR3 ECC memory in a 240-pin form factor.
Direct Hynix Replacement Module
The module is specified as a compatible equivalent for Hynix part numbers HMT451U7AFR8C-RD, HMT451U7BFR8C-RD and HMT451U7DFR8C-RD. Using major-brand chips, it allows a like-for-like swap without firmware changes, restoring original capacity and error-correction behaviour in qualified systems.
DDR3 1866 PC3-14900 Interface Limits
The DDR3 1866 PC3-14900 standard caps per-module bandwidth and density at this speed grade. Systems needing higher throughput, larger individual modules, or registered DIMM buffering cannot be satisfied by this unbuffered DDR3 specification.

คำถามเกี่ยวกับสินค้านี้
Will the 1Rx8 ECC chips on this 4 GB DDR3 1866 module ever need replacement under normal server use?
The Major Brand Chipset and 1Rx8 layout are built for continuous server workloads; ECC corrects single-bit errors on the fly so the module itself does not require scheduled replacement.
What limit appears first when this CL13 1.50 V DDR3 1866 stick runs at full load for hours?
The 1.50 V standard voltage and CL13 latency set the thermal ceiling; sustained full-speed operation will hit the DDR3 JEDEC thermal limit before any timing or voltage headroom is exhausted.
How much heat and fan noise does this 240-pin unbuffered ECC DIMM add when the server runs all day?
At 1.50 V the module draws only standard DDR3 power, adding minimal heat that existing server airflow handles without extra fan speed or audible noise increase.
