Before you start swapping CPUs, just try lowering the FSB/multiplier first: e.g. 66x2.5=166 MHz, this should work even without disabling caches.

Another thing I'd like to mention, and please excuse me as I haven't properly tested and investigated this, but I believe that the AWE64 Gold does better in "fast" machines.

I might look into this properly as I have a TON of YT video ideas lined up. Just got to find spare time to actually do it 😀

Run it with FDAPM SPEEDx where x is a number between 0 and 8. 8 is full speed, and 0 will stop your CPU completely.
I use this to run Monkey Island and DOTT on a 615MHz PIII with no problems.

Disabling internal and external caches made S&M almost unplayable, so I enabled the external to improve it, unfortunately the game crashed and I think it's going to happen again so I might try fdapm. If that doesn't help I will try with slower CPUs.
So for a 450Mhz cpu what setting do you suggest on fdapm?

Just start at 7 and try lower numbers until it works. I think 4 or 5 will do it.

I started with 2 (about a quarter "performace" which for my CPU is about 112Mhz) and the games hung as soon as they started to play music, as if fdapm didn't like my AMD cpu and it was still at full speed, then I tried 1 and it didn't change I'm afraid 🙁

I guess that means your board does not fully support APM/ACPI. You could try lowering the cpu speed the normal way then, like 5u3 said. If that doesn't work there are still like a hundred other slowdown programs, I'm sure there's one that works for you.

you know what last night I grabbed a P133 then looked at the case and imagine how I would have to disassemble everything just to access the dip-switches to fix the fsb and multiplier ...
😢

so I downloaded scummvm 😒 I really wanted to play last night, I set up scummvm to use the Tropez + and I kind of enjoyed it bit it was alittle bit like cheating.

Yep - I'd try throttle.
I believe that mobo has a VIA 596B southbridge, and according to the Throttle page it should work.

🤣

I have printouts of the relevant manual pages. Armed with my LED flashlight and, pencil (dip switches) and whatever that tool from my toolkit is called (jumpers) I then proceed into the bowls of my MS-DOS Time-Machine PC 😀

Pentium (non-MMX) is 3.3V. Set the Multi to 3.5x to get 1.5x (66x1.5=100MHz) if you want to downclock.

Pentium MMX is 2.8V. Lowest multiplier is 1.5 (133 MHz).

AMD-K6 depends on the model. They also interpret 2x as 6x, so 2.5x is the lowest multiplier (166 MHz).

I can confirm that DOTT is speed sensitive. While it works on my mobile DOS box (IBM Thinkpad 600e, Pentium 2 366), it hangs on the system on my sig, Celeron 800. Disabling cache does not help.
