This is a question that has no real answer. A part marked as a 33MHz chip is guaranteed to run at 33 MHz, and do it properly. It is not guaranteed to run at 34 or 35 MHz, and there could indeed be chips that would fail at 34. Other chips may run at 38, or 40, or faster. There is more to it than heat dissipation. -larry -- Entomology bugs me. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
