Download HWiNFO64 - a System Information and Diagnostics Tool. HWInfo64 is an application that monitors your PC's components and outs computer information about your the operating system, storage capacity, and RAM. It also displays more technical data, such as the number of logical CPUs, memory speed, and temperatures.
HWiNFO is a professional hardware information and diagnostic tools supporting latest components, industry technologies, and standards. Both tools are targeted to recognize and extract the most possible amount of information about computer's hardware which makes them suitable for users searching for driver updates, computer manufacturers, system integrators and technical experts too.

Hi Martin, in that particular SS using 4:5 strap, BCLK 125, PCIe 100.
RAPL appears tied to BCLK, ie proportionally more counts per millisecond the higher BCLK is.
For instance using a forced power limit of 40W with fixed voltage supply shows the same power delta form mains supply, 12V Rail supply and VRM IOUT for straps of 5:5, 4:5 and 3:5 and same throttled clocks at 100MHz, 125MHz and 167MHz BCLK. HWiNFO shows 40W for package power for all straps while the others including latest XTU to date show 40W, 50W and 66W respectively, each proportional to the strap used. So in this case HWiNFO is correct and others wrong.
I'm assuming you switched to using the strap ratio for RAPL estimations at some point but have maybe forgotten with all that has happened since then. Your results don't seem to be based solely on BCLK as changing BCLK to 95MHz and PCIe at 95MHz results in 38W being reported with 40W limit. I'm a little surprised this isn't mentioned in the Intel SDM or specification update unless I missed it and even more surprised that XTU is incorrect.
Indeed, there's a RAPL power adjustment done by HWiNFO, but it is tied only to those cases where a different PCIE:BCLK strap is used. So in case of 95 MHz BCLK this isn't applied.
Problem is that this is not well documented by Intel, not even in special non-public documents.
So besides the case of 95 MHz, in which other cases you see the issue? I'd really need to see the HWiNFO Debug File for those so I can check why it's not correct.
