Thank you for checking this out and posting the save files. The Type DIMM Other on the [ Machine ] panel is down to what the BIOS sets up as the SMBIOS data, notice it's also reporting 8 DIMMs when the motherboard only has 4 installed and I assume 4 DIMM slots.
When I checked SIV had some code to allow for incorrect P2B SMBIOS data, SIV limited the value to 3 for the P2B so for SIV 5.47 Beta-00 I removed this for the P2B-D with the net result that 8 DIMMs should be reported!
Now I know the P2B-D reports 8 DIMMs for Beta-01 I will apply a limit of 4, please will you try the attached P2B-D-01 test SIV and confirm 4 DIMMs are reported on the initial screen?
Does SIV do OK on your Dual Pentium Pro and 486 systems?
Edit 22-Feb-2020: I just spotted that [ GPU Info ] had issues which were triggered by the very old NVIDIA NVAPI Version 175.19 Library and I think I have fixed them so please may I have new save files so I can check.
