I'm sorry, I don't have a solution for this now.
HWiNFO relies on the same PresentMon, so we need to wait until Intel fixes it. It's most probably an issue related to a specific app/game as the majority of others work properly.
A typical conflict between OpenRGB and other software. I'm quite sure that if you would use any other monitoring tool (e.g. HWMonitor) along with OpenRGB, you'd see the same conflict.
I think I have found a potential issue in HWiNFO but need to test if the fix works.
Please try this build: www.hwinfo.com/beta/hwi64_825_5701.zip
and enable back the DIMM sensors again (hit Ins key over the headings).
Please let me know the result.
