Hi,

In order to try to answer your question, can you give us your current hardware configuration: Type of machine (laptop, desktop), CPU, Socket, RAM...?

With the Ram you have you probably have an old iMac which means that it is not compatible.

3GB 667Mhz DDR2SDRAM TM 1983-2011 ;Kernel version Darwin10.8.0 ,extensions : ACPI SMC Platformplugin 4.7.0 type Intel 64 bits Serial number WD-WCAPO 1841210

I think that with all the information I have given you you should be able to inform me so if you can't inform me let's stop this research.

Extensions… ACPI SMC PlatformPlugin 4.7.0 type Intel 64 bits

Thanks for the info so what type of processor can I install in this computer
