I put an AMD Athlon T-bird 1ghz, OEM version, in an ECS 5a board. I connected the L1 bridges with pencil. I also upgraded the bios for this board, the 010911. When I go to the "CPU PnP Setup Page", in the CMOS, it won't allow me to make any changes. Question: are some AMD cpu's just not unlockable? Even with the method to reconnect the L1 and L7 bridges ?I do understand this board is not very O/C freindly, but, I should at least be able to adjust the bus speed with this bios upgrade.
