Server ECC RDIMM Upgrade

This 32GB DDR3L 1600 CL11 4Rx4 240-pin 1.35V ECC Registered DIMM is built for Supermicro X9DRL X9DRT X9DRW X9DRX+ and X9QR7 motherboards. It delivers JEDEC-standard registered memory with error correction for workstation and server workloads. The single-module design adds capacity without mixing ranks.

Not for desktop or unbuffered systems

Buyers who need memory for standard desktop PCs cannot use this module because it requires a registered ECC platform. Builders who want to mix unbuffered DIMMs with registered memory should look elsewhere as the two types are incompatible. Systems that only support 1Rx4 or 2Rx4 population rules will not accept this 4Rx4 module.

Registered ECC with 4Rx4 organisation

The decisive specification is the 4Rx4 registered ECC layout at DDR3L 1600 CL11 1.35V. Only motherboards that explicitly support 4Rx4 registered DIMMs can use this upgrade. Verify the board's qualified vendor list before purchase.

Questions about this item

What does the 1600 MHz speed mean once this DDR3L module is installed in a Supermicro X9 motherboard?

The module runs at PC3L-12800 with CL11 latency, delivering the rated 1600 MHz data rate when the platform configures the memory bus to that speed.

How does the 240-pin registered ECC interface limit what this DIMM can do in practice?

The 240-pin DDR3L registered ECC design only works in server or workstation boards that support registered modules; it will not function in standard desktop systems and cannot be mixed with unbuffered memory.

What physical clearance does the 32 GB 4Rx4 stick need to fit in a Supermicro X9DRL, X9DRT, X9DRW, X9DRX+ or X9QR7 system?

It uses a standard 240-pin DDR3L DIMM form factor without a heat spreader, so it fits any compatible Supermicro X9-series board with an available DDR3L RDIMM slot.
