Overclocking 68882

[Piru]

Is there a real benefit of overclocking the 68882?

No, not really.

I have a 50mhz 030 board and the 68882 actually overclocks and works fine up to 66mhz. What programs use the co proc?

Excuse my silly question, but... How can you tell that it's working fine if you haven't tested it?

Through AIBB and Sysinfo

They don't tell you if the FPU is actually producing correct results. Also, they don't stress the FPU long enough to give any indication about the reliability.
