Can you have uneven memory in the two memory slots?
Hey, I was looking to upgrade my mac book pros memory when I saw i have 2 gb memory in each slot, and I was wondering can you have 4 gb of memory in one slot and 2 gb in the other or do both slots need to be even. Thanks in advance.
EDIT: I read the answers and Im a but confuse, So I will my computer run faster then before with the 4 and 2 gb? Or will it be the same because of the uneven-ness.
To clarify things here:
Yes, you can have different sized SIMMs in the slots as long as each meets the needed speed for the given model. You may also be required into installing the smaller SIMM in a given slot. While you will have more memory to use the addressing will be slower.
If at all possible use the same sized SIMMs by the same manufacture (as some manufactures chips may not play together well) so you can use inter-leaved mode.
When you have the same sized SIMM in each slot the faster inter-leaved mode is used.
