To the list:
I dug up, used and re-posted on the RH-alpha list J. de Maagd's
original posting. TRhat was a year ago. The machine I overclocked to
600, an early-model PWS 500a is running like a swiss watch one year
Another 500au - a late model with USB ports - did not do so well. It
would only take clocking to 566. Interestingly, SRM saw the cpu at 600
mhz, while the AlphaBios reported it at 566.
On the both machines I tried two different CPUs, one a 533 mhz Samsung
alpha, the other the DEC stock 500, with the same results.
I haven't got all this figured out. It may be that some mobos don't
overclock and some do, luck of the draw. It may be that the late model
mobos don't like to overclock and the early ones are less fussy.
anyway, good luck to you, Johnny
