Here's the photos (I don't have a DOS/Win3.x screenshot utility) of my 386sx and 486DLC rigs on SuperPi 1.1e (no decimals)
i386sx-16+i387 FPU / 4mb 30pin RAM / DOS 6.22Win3.11+Win32s:
4h 8min 49s
*note: Syschk, Speedsys and PC-Config all identify as being 20MHz, but the chips are stamped as 16's. Could be possible it's overclocked but I've never touched it, and the CPU is surface mounted. The systems never run unstable and is still rock solid after 20 years, even the NiCd CMOS battery holds a charge.
Well, it is faster than my 386-16, so I guess it runs at 20 MHz.
On the other hand my system is not a 386DX-16 with a 387DX but just a 386-16 / 387-16. I'am not sure how a 387-16 compares to a 387SX-16. The SX might have already the faster core like the 387DX.
Yeah, sorry about that, I didn't notice that it was a PS/2 Model 80, I just looked at it quick and thought "PS/2 386-16? must be a 55SX" like the one I have in the corner.
The 386SX should be slower, the difference was that the SX had a 16bit bus similar to what the 286 had, whereas 386/386DX had it's own 32bit bus. It's interesting to see that the differences aren't that drastic.
As for mine running at 20, I believe it is, while looking it over when I was testing some SIMMs I just got, I found it has a 40MHz Clock crystal installed. Might have been an upgrade by the previous owner, it was 4yrs old when I got it 😜
