it wont be a lc version of the cpu on these unless it was 75mhz card,and then it was another card with a flat packed cpu and fan on another card that plugged into the cpu socket.(also required a special install disk)
..and the install disk did actually say it was an lc version of the card...for the lc card.the normqal disk wont work.
the 66mhz version if its original was always and overclocked full 060,probably a 60mhz revision 5...it was on mine.
