If this is reported under XTU, then it's a bug in XTU reporting by BIOS. HWiNFO only interprets the information according to the standard.

i'm not sure,
the max value possible is 24
the max value current is 23

Maybe it reports the Max possible value always and not the currently set one.

i'm sure it reports also the current 23.

here's the debug file.

I have checked the data and all that should be reported is also reported.

there is a problem, though.

sometimes it reports 23 and sometimes 24.

Huh

As I already said - HWiNFO only displays what the BIOS reports...

the question is, why this value changes in the readings.

this is a fix and stored value in bios, which cannot change by itself.

And when does it change ? If you make a certain setting in BIOS and don't change it, then lauch HWiNFO more times do you get different values ? Or is a reset required to see a changed value in HWiNFO ?

when i start the computer and measure i get 23.

if i measure again i get again 23.

another time when i start the computer i measure 24.

but this value never changes in bios.

other values over 23 would be turbo up to 26.

that would say, multiplier current 24, 25, 26.

but max non turbo multiplier will never change and is 23.

Have you tried Intel Extreme Tuning Utility if it reports the same value as HWiNFO?

not yet tried,
cause i don't like this tool,
which edits the bios settings, with it's stored values, as soon as you open it.

i do not want to edit bios settings otherwise, than just directly in bios.


in fact, (just to explain)

this max non turbo multiplier is an important value.
if you use the max ram size, this stresses the cpu quite a bit,
cause the ram controller is in the cpu.

we found, that reducing the max non turbo just one step from 24 to 23,
makes the system extremely stable.
with max non turbo set to the real max available, say 24,
caused atleast one blue screen per month.

with set to 23, no blue screen at all.

is there no other tool?

if not, i would have to use intel XTU though, just to verify.


Cool

If you change this setting, it should be reflected in HWiNFO also in the HFM (Max) operating point. Is this same as the XTU value reported?
Maybe AIDA64 might report XTU information as well, but I'm not absolutely sure. You'll need to try it.

ok i set it to 21 in bios,

start windows and hwinfo reports 21.

so the parameter is right.

i bootet twice, value still 21.

now i set it back to 23.

hwinfo reports 23, even after 2 reboots.

Huh

yeah,
forgot HFM is right depending on max non turbo value.

, when hwinfo reported wrong max non turbo (24)
HFM was 3200 MHz

at 23 it is 3066

BTW
what is the empty CPU status value under CPU Turbo
not filled out here.

all values on system summary?

Cool

i have remarked,

that every cold computer start comes up with max non turbo = 24,
while every reboot afterwards comes up with max non turbo = 23.

I think this is a BIOS issue. HWiNFO has no influence on this.

have to find out.

i cannot imagine the the parameter is changed in BIOS.

so it can only a value report issue,
what value the BIOS reports.

Huh

however,
i found that i can read also the max non turbo parameter with throttlestop.

so i will compare it with hwinfo and tell you details afterwards.

atleast there is even no rule, that the cold computer start comes with value=24.
this was an error of mine. i didn't measure long time enough.
today another cold start came even with value=23.

hope it's not randomly.

tell you later.

the value 24 came up again after cold start.

i could compare hwinfo and throttlestop.

both display the same value 24.

Then it's definitively a BIOS (reporting) issue.
