Nonsense on a workstation.
Let kids overclock their peecees

Bye!

Tis is a followup to my own msg.

A search of the axp-list@redhat.com arhcives found the following from
1999:

--------------------------------------------------------------------------------

This machine is running as our main departmental server but is falling
sadly behind in the clock speed stakes :-( I had hoped to try it at
500MHz.

Earlier in the year Jeff DeMaagd posted a list of settings as follows
Known Calculated Calculated Status
Values Values Values

Left to Right Left to
Right to Left Right

CLK MMMM MMM MMM MMMM MMMM MMM
RATE 6543 210N N012 3456 6543 210N

533 -> -> 1010 0000 -> 0000 0101 - PWS 533a
566 -> -> 1010 0010 -> 0100 0101 - PWS 566a
600 -> -> 1010 0100 -> 0010 0101 - stalled on boot

766 -> -> 1010 1110 -> 0111 0101 - not tested - Kryotech?
800 -> -> 1011 0000 -> 0000 1101 - get a life. Or an
XP1000.

and I have been waiting to try it out but haven't had the chance until
now.
Sadly the settings don't seem to work. The existing settings for 433
are
as above but inverted - ON on the switch bank is the side away from
the processor.
I tried various related combinations but none seem to work. I am
assuming there
is no difference at this level between a 433a and a 433au - I think
that is
just the boot firmware.

I get various disk noises like it might be booting but get no video
except with the original settings - a Matrox Millenium II in a PCI64
slot,
looks like the original TGA2 card will spend its entire life in a
cardboard box :-(.
I haven't been game to leave it on long enough to maybe boot and see
if it appears
on the net in case I am doing something nasty to it!

So if anyone has any hints on what else I might try or why maybe it
might be working
but there is some reason for there being no video signal .......

Thanks,

Mark.

.... and a Merry Christmas to all ...

************************************************** ********************

So I guess I'll try some of those settings.

later

Follow-up:

I used the 600 mhz setting in the left-hand column below with my $20
eBay CPU. SRM recognized the CPU as 600mhz. Unlike 533mhz, the
machine booted RedhAT 7.2 without hesitation. AlphaBios took some
time reconfiguring, after which W2K came up in its usual clunky way.

The improvement in speed was noticeable, with no stability problems
under either OS. The CPU was good and warm, maybe 125-130 F- same
temp as it ran at its rated 533.

I will run it a monhth and maybe post an update.

Ive been running my 21164 533MHz (on a Ruffian board) at 633MHz for several
months, no problems to report. I changed the stock fan to a more meaty (tho
unfortunately noisy) model. It should also be noted, I dont do anything
"important" on this machine!

It will post at 667 but crashes shortly after post.
