I am going to finally upgrade my iMac with more ram. I want to get two 4GB of RAM to have my system be a total of 12GB of RAM. Here are my specs: Model Name: iMac Model Identifier: iMac12,2 Processor Name: Intel Core i5 Processor Speed: 2.7 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 4 GB Boot ROM Version: IM121.0047.B1F SMC Version (system): 1.72f1 I'm going to Frys next week and I'd like to know what is recommended. I'm NOT getting apple RAM as it's too expensive. If you could please let me know what would be best as to what kind of RAM that would be extremely helpful. Thank you!
