Is there anything peculiar about > K5s above 133Mhz? > When you clock a K5-166 at 66x2 you are slowing it down to K5-133 speed because the K5-133 runs at 100MHz. The K5-166 should be jumpered for 166MHz like a Pentium (66 x 2.5). The circuits inside the chip will modify it to 1.75. The only way to overclock a K5 is to use a higher bus clock (i.e. 75MHz) because of the way the clock multiplier on the K5 works. 75MHz will generally work, but 83MHz will not. At 75MHz bus clock, the K5-166 will be probed and run at or almost at Pentium 200 speeds. Stability is questionable though and depending on whether your MB supports async PCI, 37.5MHz may be too high for some PCI SCSI cards. > -- Jay > > On Wed, 27 Aug 1997, Cameron Slye wrote: > > >> > >> I've only a 166 MHz but I've made several "make world" without problems. > > > >How much memory is in that box ?
