This 128GB RAM is 100% compatible with the Supermicro SuperServer 4028GR-TR2.

What memory configurations are possible?

Memory for Core i7 5th Generation CPU: Optimal performance is achieved with 4 or 8 identical memory modules per CPU. UDIMM memory can only be used if you are using a Core i7 processor.

Memory for Xeon CPU: When using a Xeon CPU, you can use LRDIMM, RDIMM, and ECC memory. LRDIMM, RDIMM, and ECC server memory cannot be used together.

CPU in the system: UDIMM, UDIMM ECC, RDIMM, LRDIMM.

What memory technology can be used, depending on the CPU:

• Core i7-5960X: 4GB UDIMM, 8GB UDIMM
• Core i7-5930K: 4GB UDIMM, 8GB UDIMM
