Great, thanks for sharing all your thoughts! Really appreciate it.
I just ran CHKCPU and it seems that CPU is correcly identified with WB enabled.
I am also running several test using speedsys and CACHECHK, confirming L1 cache and different performance settings related to RAM speed, external cache WT vs WB, etc.
Here some of my last screenshots after some testing.

One question. Why writing to floppy drive is a good / reliable for stability test?
Thanks!
Your L2 cache and memory values are really bad. Did you try faster settings in the Bios?
Sorry to not post before, I have been dealing with a I/O write problem on the CF card that I was using. I just replaced it and now it is fine.
Going back to the cache settings, I can not get better results than the ones published above 🙁
Also, I found another great post in the forum about 486 benchmarks, and are not so better than my results.
Anyway, here are the available settings from the BIOS motherboard.
Any suggestions?
Thanks!
That is really a weird BIOS. Cache timing is "Turbo", DRAM timing is "FAST", 🤣. Normally you have to set some parameters. What are the other options?
External cache I would set to Writeback, because there is also a setting for combine tag and alter ram. That means the alter or dirty functionality should work.
Also IDE block mode On. (minor prio)
DRAM write burst maybe to Enabled (also minor prio)
So external cache WB shall bring something, at least in real world applications like Doom.
The main parameters seem to be hidden by this Turbo, fast, .....
EDIT: All the PCI bus features for increased speed seem to be disabled, too.
But we were talking about cache and memory speed, for that is does not matter.
