Targeted Server Upgrade

This 32 GB kit contains two 16 GB DDR3L 1600 CL11 registered ECC modules built for Supermicro X9QRi and X9SRD motherboards. It is intended for administrators extending the memory of compatible workstations, servers or NAS appliances. It will not work in standard desktop PCs and cannot be mixed with unbuffered DIMMs.

Straightforward Module Installation

The 240-pin RDIMMs seat in the regular DDR3L slots and require no special tools. The only common issue is attempting to install them on a consumer board that lacks registered ECC support, which results in a no-post condition. Verify the motherboard model before opening the package.

Confirm Platform Compatibility First

Check that your system is a Supermicro X9QRi or X9SRD series board and that the BIOS is current enough to recognise 16 GB registered ranks. Ensure all populated slots use identical DDR3L 1.35 V registered ECC modules; mixing voltages, ranks or buffer types will prevent boot.

Questions about this item

How can I confirm the 32GB DDR3L 1600 kit is running at PC3L-12800 CL11 1.35V after installation?

Check the BIOS or UEFI memory settings to verify the reported speed is 1600 MHz, the timings show CL11, and the voltage reads 1.35 V for both modules.

What does the 2x16GB 240-pin RDIMM kit include and what else is required?

The box contains two 16 GB DDR3L ECC Registered DIMMs. No extra parts are needed if your Supermicro X9QRi or X9SRD board has free 240-pin slots.

Should I choose the 32GB 2Rx4 CL11 kit or a different capacity for my X9SRD motherboard?

Select this 32 GB (2 x 16 GB) 2Rx4 CL11 kit when your X9SRD or X9QRi board supports 16 GB Registered DIMMs per slot and you need 32 GB total.
