SWAUG TUTORIAL: Overclocking the BlizzardPPC

[SWAUG]

It's been a while, but here is another SWAUG.org.uk Support Tutorial.

Brian Hoskins of SWAUG has produced a tutorial on overclocking the BlizzardPPC.

If you have soldering skills and wanted to push your Amiga's speed to the limit, have a look at this!

Hi Brian,

mhhh!!! those heat-sink smaller than the 68060, isn't a good choise.

Should be the same size of the CPU or bigger but NEVER smaller.

Ciao

yo man i can't see the pic or use the link  :pissed:

I have been running a overclocked Blizzardppc 603ppc 040 card for years with no problems.
Its clocked from a 040 25 mhz (standard with a 50 mhz crystal) to 33mhz using a 66mhz.
There is no extra cooling fitted although the tower case is well cooled.

oooh when did the SWAG site get redesigned?

[AmiGR]

Well, a friend tried something WAY more interesting (and risky)...
He soldered a PPC740. It's totally compatible with the 603p (voltage, data,
setup, everything). The problem is that without any BGA equipment, the
soldering was not done properly... It worked, crashed all the time and
finally the chip was fried. This wasn't up to any voltage problems.
Now, if anyone could try mounting a 740 with the proper tools...

Bit late with covering overclocking of the ppc cards this site has all the info http://zap.to/ppcoverclock and thats been around for years now. :-o

@AmiGR

Yes VERY interesing!! :-o
Did you saw the actual thing running?
Did you do any benchmarks?
What was the overall felling speedwise? (with PPC apps of course).

[AmiGR]

Yep, I saw it.
The problem is that it was very unstable, probably
due to bad soldering, as the 740 is totally
compatible with the 603 according to Motorola.
It was faster than a 603e, there were some grabs
with RC5 benchmark and SysSpeed results but I
think I lost them, I'll ask Stormlord (the guy
that did it) to resend them.

Good tutorial. I have been running my BPPC at 60 Mhz (68060) and 266Mhz (603e) for about 3 years now and I have only got extra active cooling on the 060. Does anyone know where to get 603e at 300Mhz or faster or if it's possible to solder a G3? ....that would be nice

That would be cool. :-)
