Yes it is. I've *run* 7.5 on 32 mb of ram. It IS memory starvation. That runs a LOT better with 64 or 128 mb ram than it does in 32. I've been there, done that. > > Also, all of my reading has indicated that in the PCI PowerMacs, it > makes absolutely no difference to speed whether the chips are 2K or 4K > refresh. Mixing 2K and 4K refresh chips does not affect speed except in the general sense of "Well my stuff is really slow because I have to reboot after crashes all the time". It *does* cause lockups and crashes all the time. I've personally seen this in several systems. In my own system, when I added a 4K 128 M dimm to a system at 196M with a motley assortment of 8,16,32 and 64 MB dimms, not only was the additional 128 not recognized, but some of the original memory vanished on boot up as well. I laboriously tested all of the dimms individually, and they worked, but when the old dimms were added, the new stuff didn't work. The difference was the refresh rate. When I stopped using the old dimms, not only did the ew memory get recognized, my system was also more stable than it had been before. I *have* personally seen noticeable system speedups by going to matched, interleaved memory. These were confirmed by rough benchmarking tests (how long it took to render a scene in a 3D app) and amounted to about 5% improvement. Any time you go beyond the interleaved memory the advantages are lost. If you have 32 mn of interleaved memory and 128 mb of non-interleaved you're not going to notice the difference. If you have a system that will run within the interleaved memory all the time, you will notice the difference. > -- "Wherever you go, there you are." - B.
