Ive been playing with a Pentium mmx 233 SL293, underclocking it with setmul and l2 cache disabling, with motherboard cpu speed jumpers set to 120mhz.
Enabling my Socket 7 computer's "Turbo" on top of that brings its speedsys score down to 6.44. i was wondering approximately what MHz that's at, if possible to know.
I havent really found anything that can show me the MHz through a benchmark, just benchmark scores.
And considering that the turbo still works after all that (unturbo is at a score of around 10), what might the turbo be doing to slow it so? Wait states?

any way to slow it more? I kinda doubt it
Landmark System Speed says its 20.5MHz. Is that pretty much it? I know that program uses like, a weird AT-MHz.
That program makes my motherboard make clicking sounds, so im not a fan.

Motherboard is a M-Tech Mustang R-534G

The exact MHz number doesn't really make much sense, unless you're comparing the same CPU. What's important is that 6.44 is in the 386/40 territory, so you know you have about that speed.
Also I believe it's the other way around, turbo enabled is the high speed and turbo disabled the low 😉

I dont have an actual button for it, so ive been using a jumper on the header, so i dont know whether turbo being On or Off is what makes it go normal speed or slow 🤣 i did want to say "deturbo" tho
I mostly just wanted to have an accurate reading. Is there something i can use to test how close to a 386 it is? a speed sensitive game perhaps?

I'd try a couple of benchmarks that show values for some specific CPUs like Speedsys, Norton Utilities or NSSI do. If 2 or 3 of them show a result close to a 386/40 well then this is what you have achieved.

Thanks for telling me about NSSI. This is a better scale, accurate enough for me anyway. So something like a mid-range 386.
