Just been fiddling around with my new GF4-MX460. It has a default coreclock of 300Mhz and memclock of 550Mhz. I get artifacts in 3DMark2001se at 345/685 but need to go down to 330/660 to be able to play Max Payne/JKII etc. completly artifact-free. That's still over 100Mhz memclock increase while I really didn't expect this card to go this high! It's running on a 2x 89Mhz AGP bus, and without ramsinks as for now. Anyone can tell me what speed these BGA-chips are and if it would be useful to add some ramsinks?!
