Interesting 1200

this overclock is well done and real
sysinfo reports accurate results ..77 mips which is exactly the double which does the 060/50
btw, sysinfo is the only tool that still report correct and accurate cpu test results

2x faster than a 060/50   38.5 mips
2.5x faster than a 040/40mhz  30 mips
4x faster than a 040/25mhz  19 mips
8x faster than 030/50

which is about half of the "real" mips as only one integer unit is used. SysSpeed gives the "right" figure above 150 if you try it - I believe.

sysspeed or aibb reports wrong and inaccurate results

for example sysspeed on a 040/40 mhz reports 28 mips and on a 060/50 reports 66 mips..so means is about 2.5x faster....
that's totally inaccurate...cause the 060/50 is not 2.x faster than the 040/40....only 1.3x faster
also on winuae sysspeed reports wrong and inaccurate results ...it is a really buggy tool

I tried with a 110 Mhz crystal and a 3.5v regulator, but no boot with or without any Simms...

maybe you can create your own regulator using a LM317 transistor and using a variable resistor you can create and try different voltages examples 3.35, 3.4, 3.40,3.45
also you must connect a big capacitor there to smooth that 3.3v  or 3.x line...something like 4700 mf or more .....if you do not use a big cap that line will not be enough stable for an overclocked 060

You are right.

don't be idiot what do you think ? that the 060 is a core i7 ? loi
that's graphic results are accurate of course were not done with the buggy sysspeed
and you can see I'm right that the 060/50 is only 1.3x faster than the 040/040
sysspeed reports 28 mips on the 040/40 and 66mips on the 060/50 and that's totally out of range and giving the 040 a weak weak integer result
to make sure what I'm talking about anyone can get sysspeed modules of both processors on aminet and compare

MIPS=meaningless indicator of performance.

Other than MIPS what else makes people think the 68060 @50 mhz is only 1.3 times faster than a 68040@40 mhz?

mips is something invented to calculate integer performance
you can use it to get an idea  how fast the cpu will complete certain task
however there are buggy programs like sysspeed that report wrong and inaccurate results
but the 060/50mhz will complete a task 1.3x faster than a 040/40mhz and 2x faster than a 040/25
That's because the 040 and the 060 have identical cores....in fact the 040 overclocked to 50mhz performs identical as the 060/50

and for your question ...you can use real life benchmarks to measure cpu performance
something like a picture converter or a sound converter
also someone who had both cpus...the 040/40 and the 060/50 should affirm that the 060 is not much faster...almost impossible to notice a difference on workbench
you note it on benchmarks or playing games like doom or quake where the 060 will work fast
