After a few months frustration trying to overclock my frys combo 820d an ecs 945p-a v1.1 I finally had success. The problem was that the motherboard would not allow more that a 10% overclock w/ the pcie/pci bus locked. anything more than 10% running asynch would not post and obviosly running synchronous busses would make the sata crap out after about 15% OC.
Finally I decided to do a "pad mod" and change the bsel pins so that the chip would read as a 1066fsb chip (puts it @ 3.75 on bootup). The first time I tried this it would not post, assuming that its due the the stock vcore being to low to boot it @ 3.75 I had to figure out how to raise the stock vcore. Came about a post on HARDOCP that gave a diagram to up the stock vcore up to 1.465 by using a circuitwriter pen to connect a couple of pins on the chip. Sure enough it works. Im now stable @ 3.75 w/ 1.475v @ 59c loaded and 4.0ghz w.1.525v and 64c loaded.
If anyone wants to try this let me know and I will post the links. THe same forum had 630's in a DELL doing 4.0ghz at stock vcore using the "pad mod".
