Oct 13, 2014 1:58 PM in response to georgethevetby Phil0124,★HelpfulNo. RAM memory has no bearing on your computer's files on its hard drive. Replacing a Memory module will have no effect on your files.
However, make sure the computer is fully turned off before replacing the module, and make sure you get the right type, and make sure your iMac will allow you to place a 2GB module with a 1Gb module, as often they need to be in matched pairs.

Oct 13, 2014 4:18 PM in response to Phil0124by georgethevet,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):
Memory specifications
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.
George

Oct 13, 2014 4:20 PM in response to georgethevetby Csound1,Buy 2 x 2GB chips, 4GB is not a lot of Ram so why upgrade to less? (plus matched pairs of chips are faster)

Oct 13, 2014 4:20 PM in response to georgethevetby Niel,You can buy just one. In addition, you can have 5 or 6GB of RAM in that computer by using a 4GB and a 1GB/2GB module; Apple didn't update its specifications when 4GB modules became available.

Niel - I will look into getting bigger RAM. I scanned my computer on crucial.com and they said that the 2x2GB set was the largest pack available and that you shouldn't exceed the manufacturers supported memory. Still OK to go higher?
