Paul writes, <The G3 B/W tower and several early G4 towers all use PC100 memory, but Other World Computing distinguishes between G3 and Yikes on one hand, and AGP and Gigabit on the other. They don't recommend using the same RAM in all of these, and told me that the programming and design of the memory cards are different.
Is this something I can "adjust" with DIMM First Aid? And what about using a pile of old PC100 (or PC133) RAM salvaged from PC's and Macs without knowing exactly where they came from?> 1. In my past experience of a few RAM upgrades from my BF's "Box O'RAM," if you have RAM sticks of a certain type, i.e., PC-100 SDRAM or PC-133 SDRAM, those RAM sticks will work in any Mac which shipped with that kind of RAM. IMO, OWC problably lists and discusses their RAM that way because most customers aren't going to know what kind the Mac they own needs, and will want to know "what kind of RAM will be compatible with my Yikes?" (or whichever Mac it is they have). However, if you know what kind of RAM you need, any stick of that type should work in your Mac. Sometimes, you can use a different kind, i.e., it will work, but not as "intended." The G3/266 Beige DT I had bought from the Swap List had originally shipped with 32 MB of PC-66 SDRAM (though will support third party low profile RAM sticks), and in the end I had mine maxed out and it worked fine with three sticks of PC-100 SDRAM (for a total of 768 MB). Now the bus speed on a G3 beige is 66 MHz, so the PC-100s I had in there were a bit "slowed down" on account of that (but still the machine loved that extra RAM), as compared to how they would have worked in, say my B&W, which has a 100 MHz bus speed and specifies PC-100 SDRAM. I could put a PC-133 stick in the B&W if I wanted to and it would probably work just like putting PC-100 in the Beige did. My G4 Quicksilver (to whom I gave two 512 MB PC-133 SDRAM sticks to max it out) which I bought from OWC, and when I bought them, I went in with "PC-133" on my mind, not "G4 Quicksilver 867," although I did see G4 Quicksilver on the web page while looking to place the order. The new RAM was wonderful. 2. If you go to a site like www.everymac.com, you can look up the specs on the Mac(s) you want to buy RAM for to find out what kind, as well as how much they shipped with and how much you can max them. If you buy the kind of RAM in the specs, you should be OK. 3. I've never heard of DIMM First Aid. Someone else will need to help you with that. ;-) ~Yersinia. ________ "Astronomers say the universe is finite, which is a comforting thought for those people who can't remember where they leave things." --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
