: Having an AMD486DX2-66, I made some tests. By overclocking it at 40
: (=80) MHz and slowing the bus accesses accordingly, I was able to
: run DOS and (more important) Linux for more than a day.
: The heatsink was quite cool.
I didn't touch the heatsink, but left my tower case open to give it
some fresh air (don't want to burn it the first week ;-))
: Why only for one day? Because when I tried to run Windows my applications
: crashed (general protection faults). And until someone will port serious
: music apps under Linux I need WinDog (sigh!), so I played for a while with
: BIOS hardware settings, and eventually I switched back to 66MHz.
My (local) bus accesses were increased up to 40 Mhz (no isa boards ;-(
and windoze worked like a charm (a friend of mine did some overclocking
too, but his video didn't work (I -> Spea Mirage, he ->Diamond Stealth 32))
: I wonder why this happens: maybe because Windows uses a broader
: instruction set than gcc? Undocumented instructions? Continuous
: real/protected mode switches? Bad programming practices?
^^^^^^^^^^^^^^^^^^^^^^^^^^
That's for sure ;-)
: Do you think that getting a better motherboard and/or faster memory
: will help?
: My AMD CPU is quite new, so it's probably no more able to run at
: 80 MHz.
Why change a good design? Besides, mine does work.
