I currently have 320 MB (16MB built-in; 64x4; >16x2; 8x2). How can I determine if the RAM is EDO or FPM?

There have been long arguments about EDO vs FPM. Some of the others may give you a better idea on the consensus of opinion. I had a setup similar to yours that included 2 tall 128s that I got from Newer Technologies when I bought the machine new. These are FPM RAM. When I purchased 6 more 128 sticks from Velocity Upgrades, I believe, last year I as well as everyone else was having problems with "bad" RAM which the supplier replaced (kept replacing). After going thru several exchanges the supplier's tech asked me what I was using and matched my FPM. I tested them and have been running without bad RAM symptoms. In regard to the Sonnet G3/400 processor, have you ever updated the software. The most current v2.0.1, can be found on their site http://www.sonnettech.com/downloads/proc_upgrds_sw.html#ce or via VersionTracker. Upgrading may help. If you can get your hands on the previous upgrade-v2.0 that might be better. I think there might be some issues with 2.0.1. You might find 2.0 on Sonnet's site. I've been using 2.0. Hope this helps. dan_A -- SuperMacs is sponsored by <http://lowendmac.com/> and...
