Single 4 GB DDR3 ECC UDIMM

This module is a 4 GB DDR3 1066 PC3-8500 CL7 ECC unbuffered UDIMM built for desktops, workstations and servers that accept 240-pin DDR3 memory. It operates at 1.5 V and uses a 2Rx8 organisation without a heat spreader.

JEDEC and RoHS compliant build

The stick meets JEDEC-standard timings and RoHS requirements so it can be installed without voiding the original system warranty. No extra software or drivers are bundled; the upgrade relies solely on the module’s factory-tested compliance.

Verify DDR3 240-pin ECC support

Before ordering, confirm that the motherboard or server board accepts DDR3 1066 ECC unbuffered DIMMs and has a free 240-pin slot. Check the system manual for maximum capacity per slot and whether mixed ECC and non-ECC populations are allowed.

商品問答

Will this module fit a standard desktop motherboard with 240-pin DDR3 slots?

Yes, the stick is a 240-pin DDR3 UDIMM that plugs directly into any desktop board accepting DDR3 1066 or faster unbuffered memory.

Does the ECC feature work on a regular consumer desktop or only on workstation and server boards?

ECC functions only when the motherboard and CPU support it; most consumer desktops ignore the extra bits, so the module will run as non-ECC memory.

Can I mix this 4 GB stick with my existing 2 GB DDR3 1066 modules?

Mixing capacities is possible if all modules share the same voltage (1.5 V) and speed; the system will run at the slowest module's timings.
