High-capacity sticks are double-sided with low-density SDRAM chips (16 chips). Low-capacity sticks are single-sided also with low-density SDRAM chips (8 chips). 256 MB sticks were not available when Apple developed the specification for the Beige series; only 128 MB, maximum, sticks were then available, whereas 64 MB was the most commonly available. So, Apple wrote the specification for then-emerging 128 MB stick standard. The specification states 384 maximum RAM (using single-sided, low-density SDRAM sticks), but, in truth, the actual maximum RAM is 768 MB (using double-sided, low-density SDRAM sticks). It does not matter whether the sticks are single- or double-sided. It DOES matter that the sticks are all low-density. 256 MB sticks which are high-density will report themselves as 128 MB. I suppose there are also pathological cases where 128 MB sticks which are high-density will report themselves as 64 MB. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
