Reporting issue or actual......................?

[Vimes]

Hi

Before I updated from my Z390 Master and 9900k I used HWiNFO64 to note my core clock speeds, no issues.

Sine changing to a Z690 chipset board and 12700k I have noted.....




what I am referring to is the reported bus clock of 100Mhz and then the P Cores are set to 51 and the E Cores set to 40. I would expect to see at full load 5100Mhz and 4000Mhz for their values at 100% load.

It is nothing but a minor thing but one when I am running in games to show a overlay it would be "nice" to have the values that I have set rather than what is shown unless I am missing something here..?




Thanks

This might be due to a rounding difference: 5097.5 / 51 = 99.951 MHz BCLK.
So I assume the BCLK is rounded to 100.0 on the screen, but real reported value is 99.951 MHz.
Try to increase the number of decimal digits shown for BCLK.

ah, thanks for that...........................



so adding the BCLK value and increasing the default digits shown it now reveals the 99.951Mhz and not rounded to 100Mhz.

Ok I now understand that the Mhz shown of the P and E cores are the actual values based on a Bus Clock speed of 99.951Mhz.

As that BCLK value can be rounded up can't the P and E cores values also be rounded up, perhaps not so as they are multiplied by 51 and 40, in my case, and are not a point decimal fraction only of being rounded..?
A pity, but not accurate, that for cosmetic / "nice" reasons it can't be customised to take into consideration the rounded values of the BCLK for appearances when displaying Core values.

Adding a fixed offset value would not work as the cores are going up and down, as such.

Thanks again.

EDIT: Perhaps better with a value of 3 added for the P Cores and 1 for the E cores, with 0 for the decimal places......



offset values shown for P and E Cores.....

Instead of adding a fixed offset you might multiply the value by 1.0005 to get nicer and linear-adjusted results based on 100 MHz BCLK. This should also be independent of actual ratio.

Much more elegant, and correct throughout the speed range of the CPU.........



excellent. since noting I have seen other screenshots showing similar values as mine did., via Google search. Either it is not important or the user is not aware of how they can be rounded.

Thanks again, most appreciated.
