That doesn't necessarily mean anything. When you step the clock down, you also step down on the heat generated - the heat affects the chip timings... It's all related, you change one parameter and several others change too.
I accept that raising the clock speed can possibly produce errors, but the actual cause my be a secondary effect - such as: degraded timing tolerances due to the chips being subjected to temperatures beyond their designed operating point.
There are several things which need to be cooled: video card, memory, BX chip, processors, PSU.
I use a bulk standard (Maplin - sort of like TANDY) 250W PSU, two 366's O/C'd to 550MHz, a 40x IDE CD drive, two 2GB scsi drives, one 8.4GB UDMA IDE drive, floppy, Voodoo banshee AGP, ancient ISA soundblaster 16, 3Com 3C509B ISA, and... a good heatsink and fan on the banshee, a good heatsink and fan on the BX, good heatsinks and fans on the processors, a 80mm fan pulling in at the front, a 80mm fan feeding the processor and BX fans via a plenum from the side.
I don't think it's the PSU, unless, of course, it's broken.
