I am not able to reduce CPU/MPU clock with under 10% in MAME.

I am trying on reduce CPU/MPU clock, because of their non-supportable test mode(service mode) to hear that music on these nichibutsu DVD/CD, 80s data east, some toaplan games. but, When I has attempted that, isn't able to reduce CPU clock for under 10% with MAME.
My laptop CPU has AMD Ryzen 4500U, most suitable cpu for 3D arcade games then hasn't been adjusteds core configuration until now. so, What I must do solve to that circumstance?

What does underclocking a CPU have to do with listening to music?

personally, I am intersting in Nichibutsu Toshiba TMP68301/Yamaha YM3812 CD/DVD mahjong game music and some games. but, these game wasn't able to enter service mode for hear game SFX/music. It means just run-of-the-mill to other emulation user, I has question about it ciumstance. althought it, I am finally found alternative solution for that. It's trying underclocking Main cpu under 10%, then hears to interesting sound developed by them for keep it original clock on sound function from other. (tmpz84c011)

my written english was to explain it circumstans but less proper. so I do retry explains to suitable english that means Emulated original CPU/MPU clock wasn't able to reduces under 10% in latest versions of MAME, even if I own a labtop has most stable CPU with ryzen 4500U is able to experiences on almost all 3D arcade game.

You can't get games in MAME to go above 10% ???
Even though it plays 3D games fine ???
What games in MAME are you trying to play?
None of those older games you mentioned should do that. They should play fine on that setup. The GPU will not help MAME run faster, there are certain circumstances but I'm not getting in to that now.
My best guess...

OK. I am understood yours why remarks to me. instand of I am decides to waiting for further improve emulation for these games.

I think what he's trying to say is, he wants to hear full versions of music that is playing in certain old games, and his proposed workaround is to slow down main CPU emulation to delay it sending a "stop all sound" command to the audio coprocessor.

Emulation improvements usually require more CPU power, so I'm thinking you just need to buy a better computer.

No, I think Rotwang understood correctly, while Bad A Billy did not. This has nothing to do with a lack of CPU performance. winbbs, somewhere in that catastrophe of machine translation, apparently wants to underclock (or even stop) the main CPU while leaving the sound CPU running, so that they can listen to music in some situations without the main CPU proceeding to issue a new music command.

In other words, you need something like M1, which emulates sound chips directly, so there is no gameplay to get in the way of listening to the music.
One catch with M1 is that AFAIK the latest version (at least for Windows) is a 32-bit only binary blob and hasn't been updated since 2007, which would mean it can't play things which were unemulated back then, such as the (decapped) Toaplan MCU data. Unless I'm mistaken, and a newer version of M1 actually does exist, and that one of our highest-ranking MAME devs simply hasn't updated his M1 page in over a decade.

With some creative use of the memory window in debug mode you might be able to softlock or otherwise delay parts of the game.
You mentioned Data East games from the 80's. In Karate Champ VS, address $CF02 is the timer for the high score initials entry screen. If you set it to 99 seconds that gives more than enough time to hear the whole song, which you otherwise wouldn't be able to hear in the 30 seconds it gives you.
