16 GB DDR3 Registered ECC Module

This 16 GB DDR3 module runs at 1866 MT/s with a CAS latency of 13. It is built as a registered ECC DIMM using a 2Rx4 organisation for error-correcting stability in compatible systems.

240-Pin DIMM Form Factor

The stick measures 1.2 inches high, 2.6 inches wide and 5.7 inches deep, weighing approximately 1.10 lb. Its 240-pin edge connector fits standard DDR3 desktop DIMM sockets, while the registered buffer reduces electrical load on the memory controller.

Registered ECC for Compatible Platforms

The registered ECC design means this module only works in motherboards and chipsets that explicitly support registered error-correcting memory. It will not function in consumer desktop boards that require unbuffered non-ECC DIMMs.

Questions about this item

Does the DDR3 1866 PC3-14900 interface cap real-world bandwidth at the 14900 MT/s rating?

The module runs at DDR3 1866 (PC3-14900) with CL13 latency, so peak transfer rate is limited to the PC3-14900 specification.

Will the 240-pin DIMM with 1.2-inch height and 5.7-inch depth fit my motherboard slots?

It is a standard 240-pin DDR3 DIMM measuring 1.2" tall, 2.6" wide and 5.7" deep; verify your board has 240-pin DDR3 slots and enough clearance for the 1.2" height.

How do I install this registered ECC 2Rx4 module, and what step do people often miss?

Power off, open the case, align the 240-pin key notch, press firmly until both retention clips click; the step often missed is confirming the motherboard supports registered ECC DDR3 before purchase.
