Usually, you want them to be the same, because of slight differences in timing that come from method of manufacture and internal logic design. You can generally get away with matching banks with the same address select. My main source of these things is PS/2 memory suppliers, but I don't know your bus speed, so I don't know if this will work for you. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
