Hi Niel and Phil
Thanks for your helpful and quick responses - Phil I found this on an apple support page, specifically for my model (early 2008):
These iMac computers have two side-by-side Synchronous Dynamic Random-Access Memory (SDRAM) slots in the bottom of the computer.
The maximum amount of random-access memory (RAM) you can install in the computer is:
Computer |
Memory Type |
Maximum Memory |
iMac (Mid 2007) |
DDR2 |
4GB (2x2GB) |
iMac (Early 2008) |
DDR2 |
4GB (2x2GB) |
iMac (Early 2009) |
DDR3 |
8GB (2x4GB) |
You can use a 1GB or 2 GB RAM module in each slot for iMac (Mid 2007) and iMac (Early 2008). Use 1GB, 2GB, or 4GB modules in each slot for the iMac (Early 2009).
Taking into account what you said Phil - do you think I need to buy two 2GB modules or can I just buy one and have a 1GB and a 2GB in the slots? I got this extract from this: iMac: How to remove or install memory.
Thanks again.
