upgrade BPPC?

[nasty]

I was just wondering for no reason if you can upgrade and BPPC card from say a 160mhz to a 240mhz without overclocking? I know you can upgrade the 040 to a 060 but how does it work with the ppc processor!

You might be able to, but good luck desoldering that BGA!!! :-o

Would probably work with a flash of the firmware.

erm, nope! we are speaking Amiga here! theres nothing in the BPPC/CSPPC flash, clocking related. All the job is made in hardware (multiplier/new quartz and such)

 No way! Only if you dessolder (not that difficult) the original BGA CPU and then solder a new, faster BGA CPU (that is very difficult)!:headwall:

I meant WITH changing the cpu!

Not only that..with a pc you can update the flash bios to take faster cpu's that were not supported before...so why flaw the logic?

It's not a job I'd try myself but I was wondering if it could been done! theres alot of talented people with an solder iron on this board! So maybe its another option for people that find there 160/175/200 lack without going to the hassle of overclocking the boards. So would it still be a major pain if you had all the skills involved?

 :lol: I am afraid a normal soldering iron wont do it ..

real specialists that can change 240 pins of flat pack chips can do the job.
On the Grex List someone, got 1 rework with a 300 Mhz CPu on his BPPC.

You would need specialist tools to desolder the BGA CPU from the board... And specialist tools to solder a new one on there... a quick wiki for BGA electronics will explain why!

this bloke makes it look extremely easy though. :lol:

Great link, I'd hate to have to do that... imagine trying to solder a new chip in place!?

[nasty]

Thank you guys, I now have abit more insight in whats involved. karma all round  :-D

[DoogUK]

Those guys on youtube make it all look easy, my amigas quiver with fear when i reach for my soldering iron.  :lol:

There is a thread on the A1k.org forums about someone that had his BPPC upgraded to a 275mhz CPU and it is working so it can be done for a price. I'll see if I can find the posts about it.
