Upgrading RAM on A1278 MacBook Pro to RAM 1666 Mhz
I upgraded EFI my macbook pro 13 2.4 Ghz / Can i use memory with 1666 Mhz or 1867?
Is this a good question?
The minimum required RAM: 1066 MHz PC3-8500 DDR3 SDRAM.
Yes, you can use faster RAM up to a point! I would only go up to 1666 MHz as the slower 1066 MHz is getting hard to find. You also can't exceed 16 GB between the two slots.
You're wasting your money going with 1867 or higher as the systems memory bus can't leverage it. In fact it may be too fast for the slower read/write of this system (RAS & CAS).
