Now hat would be telling

Forget the RAM disc, that's another day

So, you've got your overclock and cooling sorted, and booted into windows

1 - Screen res set tot the bench your running
2 - CTRL+ALT+DEL -> Processes - shut down any non essential services (this can be very hit and miss and depends on what you have installed / running)
3 - CTRL+ALT+DEL => Processes - select the bench your running i.e "3DM06.exe" => Right Click => Select Priority => Realtime

Back to your bench and away you go

See how that helps
