[QUOTE="dtravis7, post: 176970, member: 8287"] I have a 350Mhz G4 Yikes here in my Mac collection. They were not made to support 512Meg Dimms. I tried several just to be sure and all did what you are seeing. If there were other dimms, 256 Megs would show up for that 512 Dimm, but if the 512 was in there alone it would not even chime. A lot of older computers will not support 512Meg Dimms. I have an Asus CUBX with Pentium III Copermine, and it will only support 256 Meg Dimms. The Yikes will accept 4x256 meg Dimms for 1GB RAM. The Yikes used basically a G3 motherboard with the G4 CPU and some changes. It did not even have an AGP slot like the Sawtooth that followed it. The Sawtooth G4's support 512 Meg Dimms. I have one with 1.5GB ram. [url]http://www.lowendmac.com/ppc/g4.shtml[/url] [/QUOTE]
