The possible performance boost of EDO isn't worth the loss of error checking. If you'll take a bit of a performance hit the Tomcat I will do error correction on its memory. > > Others have posted to the FreeBSD lists that it is very difficult to quantify a performance gain with EDO memory. Hmm, I am aware that there is only a small performance gain in EDO RAMs; but many modern mainboards only support 4-3-3-3 burst with FPM, and e.g. 4-2-2-2 burst with EDO; and that should make a difference, IMHO. EDO is, however, not my primary interest, I would rather have a mainboard with 4 - 8 DIMM slots, for standard 64 MB DIMMs as they are used in Macintoshes, Suns etc. These are available everywhere for reasonable prices. For the time being, however, a mainboard that can accept 8 x 32 MB PS/2 modules would be just fine. Cheers, Michael
