Soldering MPC603RRX300LC 300MHz PPC processor into Blizzard PPC

Hi,

My last mod:

http://picasaweb.google.pl/stacho100...66MHzPPC300MHz#

[ Show youtube player ]

Initially this card was 040@25MHz/PPC@160MHz with bus speed 50MHz for PPC processor (lowest config posible).

Now it's the best config possible:
060@66MHz/PPC@300MHz with 60MHz PPC bus speed

060 CPU and 060 oscillator are socketed just in case (some BVision cards refuse to work on 66MHz).

I tried this PPC processor to work with 66MHz bus speed, but cards hung-up after 2 minutes; so I was forced to set 60MHz oscillator for PPC with x5 clock multiplier.

Just missing the heatsink+clips+5Vfan for PPC processor; I bought this card without it.
If you have it as spare I'm ready to buy

Very nice.

Who re-worked the BGA for you? What equipment did you use? And where on earth did you find all those 603 CPUs?

P.S. When can I send you my Blizzard PPC for upgrade?

Very nice!

Upgrade was done by me

Equipment is nothing worth to mention; believe me.
CPU's are from China (as 50% of the goods in your nearest store)

No problem, just please write to me on my private e-mail:

Did you use infrared or a hot air blower to solder the chip in? :-)

Was it a soldering hot air blower or a paint stripper gun?

Intriguing.

For BGA chips it's necessary to use both at the same time:
IR pre-heater to heat-up the PCB from the bottom and hotair on the IC to melt the solder joints.
And to control PCB/IC temperature at the same time.

All the theory you can find on youtube/google.

My IR equipment is really low-cost/hand made solution.
Hotair is cheap stuff from China.

Nothing exciting really...

I know that real rework station will cost 5kEUR and more, but it's far beyond my budget as I'm just hobbyist.

@stachu100

Truly amazing work sir, THANKS for sharing!!!!

How did you manage uniformly sized solder balls? Do you have paste + a suitable BGA stencil?

603e processors are with solder balls already (new and unused from old stock).

You can buy solder balls, put sticky flux on chip, put balls where they should be, (right sieve is very useful) heat them up and they solder to chip, works every time.

I saw this on Amibay, and it's an exciting piece of work. Like Alexh, I would be interested in the upgrade myself. Sending an email.

But how come the OS4 boot-screen does show 0Mhz?

I'm not the right person to answer, however question is very interesting; I've noticed this too.

You must admit that as for 0MHz CPU the AOS4.0 is veeeeeeery fast

And small update:
I've tried 5,5x60MHz, and the result is very nice

Card is working very stable at 330MHz even with standard "light" power supply.

I'm not going to try 360MHz, but should work too (I hope).

Bamiga2002 · 20 January 2010, 13:39

What kind of memory do you use? 50ns/60ns, single-/double-sided? What could prevent 360Mhz from not working?

I'm using 60ns single-sided.
What could prevent from not working at 360MHz?
Me!
I don't want to kill processor/card or both

That is why I didn't tried to change to clock multiplier to 6x60MHz.
And never will except someone will give me his card and allow for this risky experiment.

Bamiga2002 · 20 January 2010, 20:11

Can you keep full memory settings in ppc-bootmenu or do you have to enable waitstates?

I'm using standard 60ns settings.
I know that some additional performance can be achieved by playing with memory settings, but for me standard settings are ok.

Great work! Had not realized that the Blizzard PPC has connections for both PLCC and BGA type of processors.

Dimlow · 21 January 2010, 10:19

Very nice work there! I'm impressed. I have been asked to do this work but always i have refused. Maybe one day.
