I have an X10SRI-F board with Samsung LRDIMM M386A4G40DM0-CPB00 32Gb 2133MHz (one module is installed in DIMMA1 slot) with an Intel Xeon E5-2630 v3. "Auto" option in "Memory Frequency" setting is already set to 2400MHz but the results still clock out at 1867MHz. How do I change the memory frequency on the X10SRI-F motherboard?
