Is the DFI NF2 ultra infinity compatible with the gigabyte 3d rocket pro? Some reviews said that large HSF's won't fit because of some hole placement.

Also, will cheap generic 266mhz ram effect overclockability with a mobile barton 2500+ considering that the XP-m has a 133mhz fsb? Any tips for overclocking with this cpu-mobo combo?

Thanks
