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, have a look at this!

ah! its the 8-pin DIL format Oscillator thats been stopping my recent attempt.
thanks for the clarification SWAUG guys!

Quote from the page: "There has also been reports of a 300Mhz clocked PPC, but these are also not confirmed."

Here in Hungary there is a BPPC card, which has a 350Mhz clocked 603e, and 060/60, all with SCSI! But that card really in the "extreme" cathegory, since the owner replaced the 603e with a 300Mhz version. (The fastest one with the same voltage the BPPC has.) The replacement was made by a local company capable of replacing SMD parts. I can imagine that the some of the standard 240Mhz BPPC can reach 300Mhz when operated in a good environment (good cooling, good mainboard, _very_ stable power supply).

About the 060 clocking, i once tried my old CSMKII which operated very stable at 66Mhz with a 83Mhz crystal, but i had no luck. The machine started to boot, but it crashed when loading setpatch. I guess the MMU or the FPU couldn't keep up with that speed.

Anyway, the page is very well done, a recommended reading, even for people doesn't plan to overclock his cards, so ongratulations.

Well, a friend tried something WAY more interesting...
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.
If anyone could try mounting a 740 with the proper tools...

any overclocking you should also change heat compound ARTIC SILVER 5 is a good start..

i power my blizzppc direct from power supply ( ie) i disabled the regulater..

ram ( powered direct from power supply )

bvision ( powered direct from power supply )


advantage: less heat,no cd roms,motors,fans,ect in it path ( clean power )


power supply ANTEC TRUEPOWER ( TRUECONTROLL )

In reply to Comment 7 (SWAUG):
removed regulater on bvision powered it direct by 3.3 volts..also have a socket on the card to change osc..it has been changed on my card from 14.3mhz to 15.2mhz..amigod reports improved performance..

NOTE: doing the above will reduce load on 5v rail keep machine more stable..overclock better..reduce heat..

I THINK THE BVISION IS A 3.3V CARD ONLY AS I CAN ONLY FIND 5V WHERE THE REGULATER did sit..


3.3 volts comes from the big connect on power supply..

my ram chips 256MB ( memory ) has akasa heatsinks..both sides..

BVISION has thermaltake heatsink on ram chips..

most of BLIZZPPC has heatsink ( including the AMD flash chip )

all chips on BVISION has heatsink..


ALL heatsink are earth out including ram heatsinks..


i can controll voltage on both processors 3.3v,5v rail,12v rail..

i can also say that the blizppc does not like voltage below 4,8 but also not above 5.18..my machine mis-behaves above 5.18..

a1200ppc desktop..

just to add you do not need such a big fan..


on my machine i got a 30mmx30mmx10mm heatsink with a built-in fan..( fan is replaceble )..


made a cut in phase 5 heatsink 30mmx30mm put heatsink in place with ARTIC SILVER GLUE ..will still fit in a1200 desktop case..i NOW have a heatsink with direct contact with ppc chip ( with built-in fan..


if fan fails it just operates as a normal phase 5 heatsink..but you can change the fan..


the whole unit is just about 3-4mm bigger than phase 5 fan..it works FANTASTIC..


i have done lots more mods..

other mods..

added PCMCIA led

amiga sound direct to PRELUDE ( switchble in-out)

a1200 CLOCKPORT extension..

BVISION output mounted under floppy diskdrive ( faceing same way as disk drive ) as i have scsi..

BLIZZPPC modify to take double sided ram chips..

BEWARE ON OVERCLOCKING!

i am only stating here what i found out about overclock my machine..


if you have 128MB simms with a regulater in the middle be careful as mine blew up after about 7 hours..lost three 128MB simms by overclocking to high for the chip..

also you **may** need my power after overclocking..this is not to say you need a new power supply..just double the thickness of the wire..( ie ) 5v..extra power feed is also good..get it from EYETECH..


if you have the new type 128MB simms ( like me ) no regulater your ok..

In reply to Comment 4 (Alkis Tsapanidis):
Proper tool for BGA is actually just alcohol, solder flux, solder wick (to remove excess solder), soldering iron, something to lift the chip with and something to make hot air with (CEO of an eBusiness, for instance ;-) ).

Heat the chip while lifting it, it'll pop off. Then use iron and wick to remove the old solder. Clean things off with alcohol, apply a vast amount of new flux, pop chip into place and heat up again. BGA is self-centering and we're talking QUITE large balls. The important thing is not to have ANY excess solder under it, so all the balls touch their copper lands.

Good luck :-)

Actually the problem is not the tools...
the problem is the checking of joints AFTER the soldering of the BGA chip.. and there is a BIG problem..
in industry they use xrays for the checks (at least at big sony service centers).
I'm willing to try it again If I could find a G3 (740) or better an 603@300 chip.

Actually I'm searching for a ppc740 or 603 chip.. If anyone knows where to find one then please inform me at the above e-mail...
Thanks

Hi. Why would a 603@300 be better?! A G3 would be far more interesting and with better results.

Let us know if you manage to do it;)

In reply to Comment 13 (StormLord):
Like I said, be careful to remove ALL the old solder from the pads before soldering on the new CPU, and dunk it in vast amounts of liquid flux... If you need more solder on it, use solder paste applied with a syringe.

We're talking 1.27mm pitch here, that's seriously huge compared to other SMD components, so BGA really does have quite a bit of an advantage...

Good luck ;-)

oh, and this SHOULD be pin-compatible as well, and should withstand a bit of overclocking. It's also significantly faster than the 603 at the same speed: http://w2.pcsurplusonline.com/viewprod.cfm?ID=324

However, it's a 2V core (max 2.8) so might need something extra...

In reply to Comment 16 (Ole-Egil):
to go for an 604 chip I belive is a little bit uknown for me because from the hardware docs motorola send me 604 isn't pin and phase combatible IIRC... the experiment was done 3-4 years ago and is very difficult for me to remember. Also 604e has 64bit memory bus thats different from 603 and 740 that have 32bit, again all this is as far as I can remember I may be wrong , VERY wrong. My ppc now is an 160 (e) chip overclocked at 227.5 Mhz with good results. I find it more easy (cause I don't have the patient and time anymore) to go for 300Mhz 603 thats EXACTLY the same chip with same voltages etc. and overclockit as far as it goes, or get an 740 again that the first experiment shows that at least booted and I belive that the problem was to the soldering-sitting of the chip to the BGA pins.
Another thought is trying to change my 040/25 OCed at 32.5 with an 060. and actualy now I belive thats a more interesting because then I could watch those awesome 060 demos ;-)
But the common problem is finding the chips.
If I find the chips either 603@300,ppc740 and 060 I will start a site with anything I do about the project going , and after the project is finished (if succed) I will try to find a "safe" way of doing it and I will write a tutorial (but beware that will be for hard geeks who try to destroy their board and not for the pleasure of overclockers) ;-)
Anyone that can help me in any way (informations, finding chips, skills at soldering bga , electronic knowledge to research hardware docs etc...) will be very appriciated !!!!
Lets start a community Hardware project ;-)

In reply to Comment 17 (StormLord):
From what I understand the 603, 604 and 740 are all pin compatible (they are at least all 32 bit processors, ).

The chip you're thinking about might be the 620 which was 64 bit...

http://www.microprocessor.sscc.ru/chiplist/cl.2.64.9.html

Anyway, you are sure they are code compatible in the init sequence?

In reply to Comment 18 (Ole-Egil):
No, the 604 is not pin compatible with the 740 and 603.
The ones used in the CSPPC even use a different package.
