Apple first introduced the idea of interleaving RAM in the "wombat" mobo, a 33 MHz 040 board for Quadra 650s and Quadra 800s. Reports claimed a substabtial benefit - up to 20% faster? One day, I eventually found a way to measure the difference in speed using some tools from NewerTech. On a memory-only task - repeated read-write cycles - the difference was just measurable with a stop-watch at about 5% improvement. So I would concur with Bruce that that's all you'll likely see with interleaved DIMMs in a TNT mobo.
However: that's not the real benefit of interleaving. The real benefit comes from learning to be picky about RAM and where it goes. Since those days, I've always bought RAM in matched pairs of SIMMs or DIMMs, and always used it in pairs. Sometimes this is plain necessity (Pentium, PPC 601). Sometimes it just might help (Wombat, TNT). Populating a temperamental mobo design - like the TNT and Tsunami - with an iffy mixed bag of DIMMs of different sizes, densities, speeds, makes - is simply asking for trouble. Match, match, match. In general, well-matched memory just works. GWW Bruce Johnson wrote: >The Mage wrote: > > >>You can notice a 5% improvement, eh? Okay, you've obviously got a way >>better sense of time than I do...
