I've been given 2 x 512mb 133 Mhz 168 pin ECC REG SDram cards but i'm not sure if they will work in my PowerMac G4 400 Mhz AGP, it's a bit slow now and i know more ram would help. I'd really like to get a faster processor but i'm unemployed and don't have much money. Anybody got a faster processor they want rid of?
Will i damage my G4 if i fitted the ram? If the ram is no good,where can i get cheap compatible ram?
I'll be grateful for any advice 
"Officially supports 100 MHz PC100 SDRAM (3.3v, unbuffered, 64-bit-wide, 168-pin), but PC133 SDRAM is backwards compatible and may be used as well."
So yes the memory you have should be compatible and no if you put it into your computer and it ends up not working, just put in your old memory and it should be fine. Just make sure you are static free before touching the memory by touching some metal and laying of carpet surfaces.
