I have a couple of those from an old Dell that I'd love to put to some use.

Re: Beige G3 RAM
Hey Anthony, Sorry for the late reply to this message. Do not know if you have found an answer or not yet. For the most part, what you have been told is correct. You do need low density ram for the sticks to be recognized. OS 9 will see 768mgs max with the beige series of macs. However, I found in my experience when I was stationed in Turkey around seven years ago now with my beige G3/300 I had and entire gig showing under 10.2. Before that with 8.6 with the same sticks 768 was the ceiling. YMMV, ~Nathan On Jan 29, 2012, at 2:49 PM, anthonyschr wrote: I need advice on upgrading RAM in a beige 266 MHz Power Macintosh G3.

Are you certain this was a Beige and not a Blue White G3 300MHz? The BW had four RAM slots, and the limit was 1GB as 4x256MB. On the Beige there are only three RAM slots, so to get a 1 GB to recognize, you'd need 2x256MB 1x512MB; or 2x512MB. This would imply that 512MB can recognize, so that would mean you should get 1.5GB for three 512MB, but I've never heard of this ever.

I understand that the bus speed is 66 MHz, and am wondering if I must then use 66 MHz memory. I have tried 100 MHz memory with mixed success. I had the same Mac years ago, and I used a 256MB and 512MB 133 MHz Ram stick with no problem. A tech guy told me my Mac needed 66 MHz memory, but he was obviously wrong. What I noticed, though, was that some memory stick aren't compatible with the G3, when they have high density memory chips on them. That could likely be the problem, not the speed. I don't know if mixing 66 MHz and 133 MHz sticks could lead to problems. I seem to remember I had both in my G3, but I'm not sure right now. Nowadays you can easily find 133 MHz Ram sticks for a few bucks or even for free; lots of people is discarding their old Pentium PCs, and they usually have 133 MHz SDRam sticks. I see plenty of them in recycling centers. -- 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.

The speed of the RAM isn't the issue, it's whether or not it's low- density or high-density RAM. The G3 requires low-density meaning modules that are populated on both sides by chips, 16 chips total. If your modules only have 8 chips on one side they're high density and should only recognize as half their actual size.

Re: Beige G3 RAM
The speed of the RAM isn't the issue, it's whether or not it's low- density or high-density RAM. The G3 requires low-density meaning modules that are populated on both sides by chips, 16 chips total. If your modules only have 8 chips on one side they're high density and should only recognize as half their actual size. Once you get low- density RAM everything should be OK. 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.
