The Core Duo processor from Intel could not have been the primary multi-core processor accessible to customers, but it surely was arguably the one which introduced it to the lots. Sadly, the primary Core Duo chips had been restricted to 32-bit at a time when the trade was shifting towards 64-bit. The Core 2 Duo finally stuffed this hole, and [dosdude1] lately accomplished an improve to a Macbook Professional that he had all the time wished to do by changing the Core Duo processor it had initially with a Core 2 Duo from a useless motherboard.
The improve does require a bit extra tooling than many people could have entry too, however the course of isn’t utterly out of attain, and facilities round desoldering the donor processor and ensuring the brand new motherboard will get heated appropriately when eradicating the outdated chip and putting in the brand new one. These motherboards had a problem of moisture ingress which provides a pre-heating step that had been the reason for [dosdude1]’s failures in earlier makes an attempt. However with the brand new chip cleaned up, ready with solder balls, and positioned on the brand new motherboard it was able to solder into its new dwelling.
Upon booting the upgraded machine, the one hiccup appeared to be that the system isn’t appropriately figuring out the clock velocity. A firmware replace solved this downside, although, and the machine is prepared to be used. For many who could also be questioning why one would do one thing like this given the out of date {hardware}, we’d be aware that past the satisfaction of doing it for its personal sake these older Macbooks are among the many few machines that may run free and open firmware, and in addition that Macbooks which are a decade or older can simply make glorious Linux machines even given their {hardware} limitations.
