Presario C300 series are mostly 940GML - no dual core
It is very strange: The c302nr manual do say 945gml, and cpu list does have t2250 on it (the c300 service manual), buy how come it doesn't work? The only possible answer is the bios limited the cpu no over 1.8ghz! The highest in cpu list is 1.73ghz in the manual. And another evidence is the new bios f24a says it added support to m530 which is also 1.73ghz, even m530 is 965gml family. So teh answer is HP does not want you to run any higher than 1.73ghz period. Am i right?
