Well, I just installed an FX5200 on my dad's old Celeron 1.8ghz system , upgrading it from some 16mb on board crap. Now, I tried overclocking this celeron and in the bios it says 'Ratio Status : Locked', with all the frequency tweakers colored gray. Can I do anything about this or is it stuck like this for good? I've flashed the bios to the latest one and it's still the same. I'd rather not upgrade this old s478 system, but ill try and get the most out of it - help?
