Hi I need some help. Need to know, can I change my dual 1.8 to 2.0 cpu?.
Seems like a bit much for a 200Mhz upgrade don't ya think?
Now if you could put in two 2.0Ghz dual-core G5', THAT'D be worth it.
maybe he already has the processors... lay off, jeez.
I doubt if you will see any difference
My comment still stands, to which I wasn't having a go or trying to be rude. Simply stating that to swap the chips around wouldn't make much difference.
I agree, you can better put more RAM in it, over 2 GB it is faster and put a better graphics card in there (X800), that are the most things that would make a G5 faster. Maybe then put a Raid 0 in it. Also I thought you couldn't upgrade the procs in a G5?
A guy said it isn't too hard to sniff the Service Processor's bus and find out where the Service Processor has the speed code located so you can hack the ROM and reburn it -- not hard if you know about the CPUs.
It is the people that don't know much about them that would find the swap difficult, program to acclimate CPUs, swapping resistors, burning ROMs, etc.
It doesnt look like its socketed: PowerPC G5 so you may have some trouble in actually upgrading it.
Not without a lot of sophisticated equipment. You'll just end up with a dual-nothing PowerMac after you fry all four CPUs.
I think lots of questions can be answered as: "If you have to ask, then no, you can't."
Cheapest way to go from 1.8 GHz to 2.0 GHz is to sell the old machine on eBay and buy a new one.
If you really want to do it and see a difference in performance, try a 2.5Ghz Quad G5 CPU.

If you go to ...
You can see where the math and all the other stuff required for bringing the machine up to a stable clock is a problem -- so copying the EEPROM may be better than hacking it.
