According to Intel documentation, the supported memory frequency could vary depending on the CPU and memory configuration for Intel ADL-S, RPL-S, RPL-S Refresh Platform.

Please refer to the following table for the maximum supported memory frequency in different scenarios:
 

For 12th gen Alder Lake-S processors:

*DPC = DIMM per channel
*1R = Single Rank Memory
*2R = Dual Rank Memory

 

Please refer to the following table for memory configuration of ASRock Industrial 600 series motherboards:

Model Name

Memory Platform Design

IMB-1315

UDIMM 1DPC

IMB-1713

IMB-1316 / IMB-X1316 / IMB-X1316-10G

UDIMM 2DPC

IMB-1714 / IMB-X1714

IMB-1237

SODIMM 1DPC

IMB-1238 / IMB-X1238

IMB-1239-WV

IMB-1240-WV / IMB-X1240-WV


For example, if you use i7-14700T on IMB-X1714, the maximum supported DDR5 memory frequency would be:

DDR5-4400 when installing 2 sticks of memory on A2 & B2 slots
DDR5-4000 when installing 4 sticks of single rank memory

DDR5-3600 when installing 4 sticks of dual rank memory
