Virtuella RAM and cpu clock

can i use a flash drive to extend the ram and maby use it to extensd the cpu clock

I wouldn't think so, technically you could mount swap file on a usb drive but it won't help your cpu clocks and probably wouldn't make much difference

you can have a swap partition on a external HD [try not to use flash as it will die fast [ depending]]
you cannot increase the cpu clock speed with anything plugged in - though you can overclock it

and how would a do that can you post a link to a tutorial

search.php?keywords=swap+on+sda will help
