I have a Duron 850 on order which will be used with a Asus A7V133 and Globin Win WDK38 Fan/heatsink. I want to run @ 1+Gig and want to know if connecting the L7 bridges will really be necessary? I will of course unlock the L1, but when I put on the heatsink, I don't want to take it off for the L7s. So should I do both before putting ont the heatsink? Thank-you very much, your knowledge is greatl appreciated.
