Timings seems more likely.
mr bios wants to run more tightly. Try increasing the ram access waitstates a little with caching on.

Or, changing the cache mode, if it is set to write thru, to write back.

I'm still gonna ask.

No memory speed setting ?

Not really buddy..unless timing adjustments are buried deep and I haven't discovered them yet..
There are 14 pages in the bios ...I'll post them up for you to look at..

..last 4

PC150012 😀

side note, which I'm unsure if it's sorta bypassed by using a amd k6/2, the 430TX chipset only caches up to 64M of memory.
Anything higher will suffer some slowdown.

anyway... play around with the first three settings if you feel like it, yes, even the EDO/FPM timing.
I don't know if they might have an effect on the SDRAM you seem to be using.

At this point I have nothing to lose by trying...
No wait state tweaking...and unsure if the fpm edo setting would be relevant...but hey..It took me this long and a lot of waiting..just to discover disabling the cpu cache gets results.
Is it possible or even likely that this industrial setting mrbios was never written or modified to be used with K6-III.
who knows..
certainly not me

K6-III ? mmh I only see it reporting a K6/200. no idea though.

MR Bios's tend to have just the settings that one needs, but it tends to support/drive the hardware better from the start, like the 4 floppy drive support.
This in contrast to the AMI bios's where with the use of the correct program, like the old amisetup? (i think that's what it was called), you could change so many settings, some would work, others wouldn't do a thing.

What CPU are you actually running on that board?
also, try running the speedsys benchmark. the graph bottom right should tell you something about memory/cache throughput. Compare them with cache enabled and disabled.
