(Provided voltage is the ONLY difference). However, if you slow down their access, particularly bus rate (the actual frequency they are hit at) you may have some success running them undervoltage. I was able to get 5 volt Macintosh EDORAM to work in a 3.3v spot by running it at a creeping 66MHz with the conservative access timings. On the same motherboard, I could get 60ns 3.3v EDORAM to work at 83MHz with the agressive settings. OTOH, the Macintosh RAM would not function at any speed in my current motherboard, even 60MHz with the slowest settings. So your milage will vary by motherboard and perhaps processor choice as well. Not something to do for a production machine, or something hard to get into, but just fine for a toy box. -- jkenner @ mindspring . com__ I Support Linux: _> _ _ |_ _ _ _| Working Together To <__(_||_)| )| `(_|(_)(_| To Build A Better Future. |
