B&W G3 CPU in a Beige G3 - 10/19/05 11:02 PM

Anyone tried putting a Stock standard Apple blue & white CPU into a Beige G3? I got one cheap and was wondering if it actually works?

Would higher bus ratios be possible? like a 83MHz bus?

I have the current 300MHz CPU set to 333 no problems and was hoping to clock the 350 from the Blue & white to 375 with a higher bus.

Yea, a cpu from a b/w works fine in a beige g3. And the 350 chip should easily be able to go to 375. I clocked my old 350 b/w to 400 mhz without problems...

Wicked! So 400Mhz might be possible. Did you add any fans? Still need to know if higher bus ratios are obtainable?

Higher bus speeds are doable, but you may lose stabilty. Make sure you have faster ram in it too. I am planning to try this also. It will help if you cool the system chip.

Are there any particular types of clip on fans that would fit in a Beige?

I've seen some cheap PC fans & heat sinks that may fit but are uncertain they would work as efficiently as the orignal heatsink.

Could i fry the CPU if it isn't properly heatsinked?

Get a rev. 2 B/W g3 heatsink and put a small fan on it, that will fit. Yes, if it is installed incorrectly it could cook you cpu. As for the system controller, find a small heatsink and attach it with some heatsink tape or heatsink glue.

Hmm yea, you should be able to go for 400 mhz. It works fine in my b/w, but then again i guess it has a better "cooling-design" than the beige.

some beige owners have gotten the bus to run at 83mhz. I think it lowers the pci bus down to 30mhz from 33. worth the trade off.
