OWC 8GB DDR3L 1600 ECC Registered RDIMM

This 8GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V operation. It uses a 240-pin registered DIMM form factor with 1Rx4 organisation and ECC error correction. The part number is 1R6T31R408GB and it carries no heat spreader.

Suits Supermicro X9DRL X9DRT X9DRW X9DRX+ X9QR7

Designed for workstations, servers, NAS systems and routers that require registered ECC memory. It will not work in standard desktop computers that use unbuffered non-ECC modules. Builders needing unbuffered memory or a different pin count should look elsewhere.

Registered ECC DDR3L 240-pin 1.35 V specification

The single decisive specification is the registered ECC DDR3L 240-pin 1.35 V interface. Only systems that explicitly support this exact combination will accept the module. Verify the motherboard manual before purchase.

Questions about this item

What does 1600MHz mean once this module is installed in a Supermicro X9 board?

The module runs at 1600MHz DDR3L speed, delivering PC3L-12800 bandwidth when the motherboard memory controller is set to that frequency.

How does the 240-pin DDR3L ECC Registered interface limit what I can mix with it?

It requires a registered ECC slot and cannot be mixed with unbuffered or non-ECC DIMMs; the board must support registered DDR3L operation.

Will the 240-pin 1Rx4 stick fit the DIMM slots on my X9DRT motherboard?

Yes, the 240-pin DDR3L RDIMM form factor matches the X9DRT series memory slots exactly.
