128 GB DDR4 ECC RDIMM for Supermicro X11

This 128 GB DDR4 2933 MHz CL21 registered DIMM is built for Supermicro X11DPFR-S, X11DPFR-SN, X11DPG-HGX2, X11DPG-OT-CPU and X11DPG-QT motherboards. It targets server and workstation administrators who need maximum capacity per slot with error-correcting registered memory.

Verify registered ECC support

Your motherboard must accept DDR4 288-pin registered ECC modules and allow 4Rx4 organisation at the intended speed. This memory cannot be mixed with unbuffered DIMMs and will not function in standard desktop platforms that lack registered ECC support.

Low-voltage operation reduces thermal load

Rated at 1.2 V, the module runs within standard DDR4 power limits for registered server memory. No heat spreader is fitted, so airflow across the DIMM slots should be maintained according to the chassis and motherboard design guidelines.

Questions about this item

What is included with the 128GB DDR4 2933MHz ECC RDIMM and what must be purchased separately?

The module itself is supplied. No heat spreader, cables or additional components are included. Extra DIMMs for multi-channel configurations must be bought separately.

Which capacity or version of this registered ECC memory should I choose for my Supermicro X11DPG-HGX2?

This part is a single 128GB 4Rx4 registered DIMM. Select it when you need maximum density per slot; choose lower-capacity registered ECC modules if your budget or slot count requires smaller increments.

What does the 2933MHz rating mean once the DIMM is installed in a compatible server motherboard?

The module will run at up to 2933MHz CL21 at 1.2V. On boards limited to 2666MHz, 2400MHz or 2133MHz it will automatically down-clock to the highest supported speed while retaining ECC and registered operation.
