Yes, I know this has been talked about, but sometimes people answer, sometimes don't. And maybe be know someone had the guts to try iit 8-) So there are some PPC, processors that are exactly the same but have diferent clockspeed. Has anyone took advantage of this to solder in a faster 603 or 604 in his/her card?! :-o 8-)
Then let us know...
Cheers

Didnt some guy with access to the appropriate surface mounting technology stick a 300MHz rated 603e from a mac onto a blizzard?
I seem to recall something like that a while ago...
-
You NEED to remember... :-o 8-)
I guess there's nothing like trying but it would be encouraging to know somebody else had results...

Hmmm

Hi all !
A few days ago, I replace the original 240 MHz 603e PPC processor with a 300
Mhz one.
And it's working fine on 330 Mhz frequency. ( but works at 350 MHz maximum
frequency)
Speed results:
603e
240Mhz(old) 300Mhz(new) 330Mhz(overclk.) 350Mhz(overclk.) 366Mhz(unstable)
--------------------------------------------------------------------------
295Mips 368Mips 406Mips 430Mips 450Mips
182MFLoops 227MFLoops 251MFLoops 266MFLoops 278MFLoops
Can anybody help me in increasing the PPC RAM access speed ? 8)
Unfortunately I didn't use more than 60Mhz bus clock frequency with the
G-Rex board. Before G-Rex, my PPC+Bvision worked fluently at 66.6667 Mhz
bus clock frequency.
Regards

Ive always thought that it could be done, but someone was also telling me about that the voltages are different, and a few other things. I would like to see a fast PPC on a blizzard that was custom done :-)
-
Thx NeRP. I think I'm gonna try it some day or another. If I do I'll post the results. I don't have the necessary electronic equipment though
-
jose: hah u still need to do alot of changes to get something like this work-..
also , if this is the g3 i heard about (there was only one right??) it died pretty fast...
overclocking is fun....till it says !bzzzztztt pofff! :)
-
There was one guy, don't remember his name, that worked in a company were the produced o
mikro processor board.
He borrowed one of there machines and used it to solder on a G3, and it worked for about a couple of houres and then it fried = no heatsink, no clue why he didn't use one.

Have you (all) an idea, what evil work, is desoldering a 603e from a Blizzard?
603e has some micro SMD components, placed through the CPU pins . . . .brrrr!!!
Good luck :-)

I've heard that it should be possible to solder a 060 onto a 040 socket if you manage to lower the voltage. I assube that it should be possible to do the same with PPCs.
Wasn't there a G3 accelerator similar to the Overdrive Pentiums availible for old 3- and 486s?

mhhh! another kind of work!
On Blizzard/CSPPC is quite simple to replace an 040 with an 060.
For the PPC, is a very hard works, even for a good tecnician (with a professional desoldering station).

PS- by the way . . .your avatar, crash my system :-) . . . sometimes. Any suggestion?

So, there exist G3 models that are pin compatible with the 603 then? I had no idea...

@GPT:
Very cool!!. WHO was that guy?
I know people that could do it for me, but the equipment might be the problem.
-
The pins isn't the same on the G3 and probably not the Voltage either maybe not even the size, but he did it.
And it's teoretical possible to do that for those wo don't belive me. They are (603/4 and G3) complatible.
-
I read the G3 worked for over 4 days but then shorted out and fried (hadnt been soldered very well). I wonder how games performed on it?
-
update your datatypes?
:-)
-
If, at all possible, socket your cpu. Most likely it may not happen, but better not to go thru all the trouble to replace another cpu you just soldered into when it fails. As for overclocking, better get a reliable heatsink and fan. And, from the lack of space of using a heatsink and fan, I'd say, "Good Luck, " unless you placed your motherboard in a tower.

with the cyberstorms I have read that the 604e/233 uses 2.4volts and the mach5 models (from 240 to 400) between 1.8 and 2.1... The 060/040 use a voltage regulator, do you know if the ppc has another one? If there is such a component I guess it would be easy to change it for the right one... and get a 400Mhz CyberstormPPC (if the multiplier allows that, of course...)
