Not just any. My buddy had a G4 and bought some cheap ram off e*bay that worked in an old PC but was not compatible with his Powermac. Best to check that it is Mac compatible.

I have a box of Kingston PC133, was hoping something in there was compatible :)

Please take note that these machines are very picky about RAM. Low density, PC-100/133 SDRAM. I have the powermac G4 that precedes yours, the "Yikes" which is a PCI graphics.

The B&W G3 and Yikes G4 (same logic board) are far more picky about RAM than the AGP towers. The memory controllers from the Sawtooth on are far more compatible with different timings.

Thanks for the info Zen.

Not to hijack the thread, I have those two, the B&W G3 and Yikes. Both are still working, both running OS 9.2.2. And they are picky with RAM.

I believe for PC-133 it should be CL3 3-2-2 or PC-100 CL2 2-2-2...

Tossed 4 Kingston 512mb sticks in and it booted right up. Reading 2GB of Memory. I was planning on at least half a day to get even 512mb total working :)

They just cost 10x more ;)

Ah that would be a another discussion thread. Anyway, it is just a pity the machine is limited to 2GB max on the memory because of the firmware. I have seen 1GB sticks of PC-100 SDRAM. If it has 4 slots, 4 x 1GB sticks can be installed, would it still be read as 2GB or the mem controller would not read all?

Aren't the 1Gb PC100/PC133 ECC or high density ram?
