It might not have a full contact when at room temperature, but as it heats up by 10-20C inside the case it might expand and give full contact. This could apply to copper runs on the board, contact points from the board to the memory slot, contact from the slot to the memory. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://www.Alameda.net/~ulf/resume.html
