can I replace an E8135 with a T9900?
The E8135 is a custom CPU for Apple so there is no data sheet for it. Here’s the other CPU: Core 2 Duo Processor T9900 Apple never offered a T9900 CPU in any of their systems so its likely the systems BIOS won’t support it. The T series on the most part are older CPU designs (the ones Apple used). So it wouldn’t make much sense. Why are you doing this?
