had no intentions of OCing anything in my crappy spare PC in the basement since it's based on an old Intel D815EEA mobo with no options in the BIOS to OC, or jumpers..... but I got ahold of an old Sapphire Radeon 9600np (324core,200mem) 128mb with passive cooling..... so, like any norman human being would do, I immediately popped the heatsink off and applied a neat layer of AS5, reinstalled, and mounted a fan on the heatsink.... ran ATI tool, set the core to 475 and the memory to 250, runs like a charm..... Aquamark3 goes from 16,000 stock to 22,000 which seems good for a P3 1GHz machine...... no 5mhz incremental OCing for me, I figured if I f'd the card up, it was no huge loss, got a spare Voodoo3 I could always pop in here, or my TNT2 m64
