Dear Johnny & list:
You can probably just change the clock setting for your CPU. The 21264
chips are mostly capable of running at higher speeds. Just change the
dip switch setting:
left to right 0010 0101
where 0 is down and 1 is up (on)
Feel your cpu heat sink after you make the change. If you can keep your
fingers on it is is OK.
I have a PWS 500 I OC-ed to 600 and have been running for a year, no
problems. Some people say the Samsung CPUs run cooler/better than the
DEC originals. What this means to you, is you probably don't need to
buy a 600 mhz CPU, just O'Clock the one you have.
As far as the cache module goes, the best one is the 4 meg unit. I've
got one and it doesn't make much difference. The gurus say you *might*
need it for integer-intensive work.
It's probably not the best place to put your money.
good luck
