Today i put 2 no-name 256 MB Memory modules in. Success :) Also double sided... (the 2x128 memory modules which are plugged in too, are one-sided. Are there 512 MB four-sided modules? :) Have some 1GB 4-side (2 double-sided plates connected together) modules.. they look really funny :) and if there are 512MB 4-side modules, maybe you have then "2048 MBytes of system memory" because the chip size should be the same like on 256MB double-sided and 128 MB one sided modules. >>>show mem 768 MBytes of system memory Bank # Size Base Addr ------ ---------- --------- 0 512 MB 000000000 1 256 MB 020000000 Total Bad Pages = 0 Total Good Memory = 768 MBytes I tested a bit wit allocating 600mb of ram and filled it with rand() in C. Seems to be, that the RAM is still cached. No performance problems (First i thought, only 512 MB are cachable -> performance went down when you have more ram.. but it's still performant :) have to get 2 more 256 modules now :) Greetings, Oliver -- Oliver Lehmann, lehmann@ans-netz.de, http://www.pofo.de/ http://wishlist.pofo.de/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
