Hello all! I just upgraded my iMac 8,1 to 6 GB of ram. I put the 4 GB card in slot 0 and 2 GB in slot 1. Everything seemed register fine so I went ahead in upgraded the SSW to Lion. It was odd because only during the install of Lion when the system restarted I would hear a beeping sound and would have to manually shut it off and restart it. After the install finished the system restarted fine again also software update was run and it still restarted with that without fail. Is this something I should be worried about? The RAM I installed is called Hypervelocity and It should have a lifetime warranty but either way I would like to test the new RAM a bit more than just seeing 6 GB appear in system profiler.
