Andy, for a S478 upgrade just get one of these 730 chips and set it to 200x12=2.4GHz for some great gaming performance Should be very doable and given the very low heat output of these chips it will be very silent too.
Thanks for the info, with my memory I will not need any mod I don't think due to the 533 FSB speed as default, gives some headroom.

Just one more question, on the web it does not mention the P4C4800 as being applicable but only 865, but I guess from your experiments it is, but they also mention a special BIOS for the M, from your comments I think you are just using the standard BIOS and just turning down vcore for cpu and making sure it boots at 200Mhz ? Do the 875 features have to be turned off, such as PAT ?

This takes me back to my trusty BX motherboard where I bought a 100Mhz PIII and overclocked it to the same value as the highly expensive 133Mhz FSB PIII's .. 650Mhz to 933+ MHz ..those were the days .. that was an another great chipset, the BX.

This is making my mouth water, my gaming machine has been worrying me for a while, this will give it some new legs. Thanks for bringing it up in the 3dmark forum, I never go in the Intel one ! Good luck with the 40k + macci.
