What about a gateway gt5464 with a pentium 4 1.6 with a Coconut Creek mobo? at least 1.8 GHZ would be nice...
It (a "code") might
exist for that, but you would have to call Gateway (that's the only way, unless someone from Gateway is here on the forums and has intimate knowledge of that one specific model). They would obviously be VERY hesitant to tell you, though.
Either way, I agree with nna2, there's no point in OC'ing that thing anyway. Crap is crap.
