Throttlestop Set Multiplier 6700k

hi Kevin. First want to say thanks for this tool. Its literally the best tool I ever used ever for performance tunning. It saved me a lot of money over the years and has helped me getting my laptop and desktops running much cooler and better.

I have a question for ages i could never understand. Have a 6700k on a z270 pro gaming MB. One specific game I have that runs on an emulator has a weird bug that causes it to run too fast on some cpus. On my 7700hq runs at normal speed but on the 6700k runs too fast. Like 30% faster. This issue is known to affect many users on different cpus.

The original arcade hw in which the game ran is an older intel cpu that runs at 2.8ghz base clock. I am able to get it running at normal speed if I adjust the base multiplier in the bios from 42 to 28 on default bclk 100mhz.

But if i simply adjust the max turbo speed under fivr to 28 it still runs the game too fast.

I read a post (old) here in which you replied to a user that you can only use the multiplier option in TS if you disable speedshift. For obvious reasons id like to keep that enabled so the cpu runs at a lower frequency and hence less voltage.

I have yet to try disabling speeshidft in the bios to try using a lower multiplier via TS since its locked with SST on. Im assuming that will work.

Can you explain to me the difference between setting multiplier to a lower value in bios VS capping the max turbo to same speed via TS. Just would like to understand why 1 works and the other doesnt.

Thanks in advance.

Some internal clocks that Windows use are calibrated after the BIOS but before Windows boots up. Using ThrottleStop to change the speed while you are in Windows might change the accuracy of how some old school software / games measure time. No software should be using the CPU MHz to measure time but it sounds like that is what the game you are trying to play does.

Different versions of Windows use different default clocks. Here is some more info to switch between two different internal clocks. That might make a difference to your issue.

Ever since i moved from Windows 7 to 10 i have this problem and i get fps drops from valorant because of it any idea how to fix it? its a pain disabling it everytime i turn on my PC

Whether you use the Set Multiplier option in ThrottleStop or if you enable Speed Shift and change the Speed Shift Max value in ThrottleStop to change the CPU speed, the results or the bug you found will probably be the same. Any method you use to change the CPU MHz while in Windows is not good for that game you are playing.

You are welcome. I like using TS too! Kind of like a Swiss army knife. Lots of settings to play with. No one using a computer with an Intel CPU should be without TS.

I wrote a little program many years ago that can report the frequency of the clock that Windows is using. That might be useful when testing. Let me know if you change Windows timers how that works out.

Thanks a lot. Will do.

Yeah youre prob right. No matter what i do to change clock after boot doesnt work. One guy said he got it working with xtu older version. Guess i need to try that. The output from wintimer is identical using bios to cap multiplier or using TS.

To make things worse its actually a linux game emulated lol
