Thank you for joining the Intel communities.
The Intel® XTU reads the information from the BIOS and whatever options are available in the BIOS the XTU will be able to read it.
I’m not sure at this point why one listed the memory options in and not in the other, could you please upload one picture of each where is showing those options?
Also, I would recommend contacting your motherboard manufacturer to see if they are aware of it or to see if some configuration is missing in the BIOS.
I have a similar issue than you, the difference is that the behavior shows in both my computers:
1.- MSI X99S Gaming 9 AC, i7 5930k, 4 X GSkill Ripjaws 4 8GB @2400Mhz
2.- MSI X99A Raider, Xeon 2630L ES, 2 X GSkill NT Series 8GB @2400MHz
In both cases when I install XTU (either the MSI or the intel version) It works fine and shows all the options as expected, but after I reboot, several options including the memory tab are gone or grayed out, also the value ranges for numeric options now are displayed using format using several digits after the decimal point. If I uninstall the application and reinstall it again, the options will show up again, but will disappear after another reboot.
In this case, I suggest using the MSI Intel Extreme Tuning Utility which is the recommended utility for your motherboard bios, this tool is most likely customized by MSI and for some reason is not detecting correctly the information from your motherboard BIOS, at this point at suggest contacting MSI as they are more familiar with this system component and the BIOS configuration.
I can get better support here:
