Personally, I find SIMMs with high chip counts to be highly suspect. Also, that particular motherboard has 8 SIMM sockets, which gives you a 256MB max with 32MB simms, and expansion to 512MB once better SIMMs are available. > Does anybody have a good source of 16x36 SIMMs built from fewer than 36 > chips per module?
