I got a 2011 22.5 i7 iMac. According to the Apple site. I can configure my memory capacity up to 16GB (4x4GB). Therefore I'm assuming all iMacs has 4 memory slots. Bear in mind that I have not open my iMac to confirm this.
Having said that. I'm thinking of adding more memory to mine. I do not want to buy anymore 2GB so I was thinking of getting two 4GB.
If this is the case. Will I be able to keep the existing 4GB to the original slot. Then add an additional two 4GB to the remaining slot. This will give me 10GB. Is this configuration allowed?
Lastly is 8-10GB of memory good enough for routines such as LR, Aperture, and PSE, but no video editing.
The reason that prompted this question is because Aperture seems to be halting on me. I chose to go the least amount of memory when I ordered my setup. Knowing that I can do it myself at later date.
Thanks in advance.
