8GB DDR3 1866MHz ECC RDIMM

This 8GB DDR3 module runs at 1866MHz with PC3-14900 rating. It features ECC error correction and registered buffering for data integrity. The stick uses a 2Rx4 organisation and operates at standard 1.5V voltage. It is built for server and workstation platforms that require registered DIMMs.

Suits servers needing registered ECC memory

Systems that accept unbuffered non-ECC DDR3 cannot use this module. Buyers who need higher capacity per slot or a different speed grade should look at other options. The 240-pin form factor fits only DDR3 registered DIMM slots.

Straightforward DIMM installation

Align the notch with the slot key and press firmly until the retention clips engage. The most common issue is inserting the module into an incompatible unbuffered slot. Always confirm the platform supports registered ECC DDR3 before fitting.

Questions about this item

Does my motherboard need a 240-pin DDR3 RDIMM slot to accept this 8 GB registered ECC module?

Yes, the module uses a 240-pin DDR3 DIMM form factor and requires a registered DIMM slot that supports ECC; standard unbuffered desktop slots will not work.

Can I mix this 1.50 V CL13 1866 MHz RDIMM with older 1.50 V registered ECC DDR3 modules running at a lower speed?

The motherboard will clock all installed modules to the lowest common speed and tightest timings, so the new stick will downshift to match the slower modules.

How can I confirm the module is detected as 8 GB ECC registered running at 1866 MHz with CL13 timings after installation?

Check the BIOS memory information or run a system utility such as CPU-Z or dmidecode; it should report 8 GB, DDR3-1866, registered ECC, CL13, 1.50 V.
