Unsuccessful attempt to install 604e@350MHz onto Blizzard PPC

[stachu100]

Hi,
 
As an experiment I tried to put 604e@350MHz CPU onto Blizzard PPC.
 
Modification done:
1) PPC CPU replaced
2) Oscillator 60MHz with x5,5 which gives 330MHz frequency for CPU core
3) Removed original 2,5V voltage regulator
4) 1,9V/10A voltage regulator added ("classic" type soldered ad-hoc just to proof the concept)
5) +5V from power supply connected to 1,9V voltage regulator directly; without it I've measured 4,5V on the Blizzard PPC instead of 5V
 
As a results card is booting without RAM, but PPC is not recognized:

With RAM installed I have RAM error:

So I assume that Blizzard PPC software inside flash memory cannot init 604e correctly (lack of proper routines inside Blizzard PPC flash) and/or logic on the board is not working with 604e because onboard CPLD IC's are not adopted to serve 604e.
 
Anyway as I'm not a genius :lol: I will drop the idea to modify Blizzard PPC hardware/software and just un-solder 604e and put standard 603e@300MHz.
 
But at least I tried.

looking at the photos DO YOU KNOW WHAT YOU ARE DOING?

im not going to explain whats wrong but im going to leave it up to other users.

the card has every single right not to work.

I was expecting such comment from you.

Are the parts even pin compatible?

[bloodline]

Isn't the BPPC BGA... How the hell did you solder that!!

[stachu100]

Almost...
Differences are well described in hardware specification for both processors.

[stachu100]

Thousands of people are doing this every day; it's just the question of equipment, some knowledge and some manual skills.
Nothing special really...

[delshay]

i also solder in BGA, iv being doing it for over three years so you can kind of call me a expert.

so i can choose how im going to solder/install in a BGA component,semi-auto or almost complete manual and belive me when i say manual i mean by hand.

Hm, I see you have only 1 ram card inserted. I always thought the 2 memory banks must be filled with 2 cards of the same amount, just as i have in my blizzppc.

you first need to identify the problem with the modifcation ( yes i do know the answer ) someone sooner or later will post whats wrong.

[stachu100]

Your post gave me an idea to try insert 2 SIMM's
 
I'm 100% sure that standard Blizzard PPC (without 604e modification) is working with only one SIMM; checked several times.
 
For example:

But it's worth to try

Of course you know the answer; it's wrong PPC frequency multipier on picture.
I'am correct?

Well i checked the manual (yes, i still have one) and it should indeed work with 1 simm card.

@delshay
Since you know the answer as stated, why don't you give some help or hint to Stachu100? Why the mystery? lol
Don't get me wrong but since I don't think you compete for anything... You could help him a bit.
Anyway, maybe I'm on the wrong side but your reaction seemed like you were angry of him trying something @ his own hardware without hurting anyone

Time to sell it on ebay as an AS IS item.
