In the last month, for some unexplained reason, my one year old 21.5-inch iMac will get a RAM warning (three beeps, pause, three beeps). Then, sometimes it is a kernel panic. This happens about three or more times a week. I took it in to Apple and they said they could not duplicate the problem I was having and handed it back to me. The iMac is under warranty till 2014.
So what next?
You are correct in that it’s indicating a RAM error. Three beeps, pause, etc. Now, often a RAM issue can be resolved by re-seating the RAM. This is because it may have been nudged around during shipping. To re-seat, you can remove and then re-insert the RAM.
I would also check that the environmental conditions in the location where it’s reporting the error have adequate airflow to keep the machine cool and ideally, not in prolonged direct sunlight. In cases were a RAM card has failed, it usually is a permanent failure. This scenario however, suggests that perhaps the card is not completely seated.
I hope this information has been helpful for you.

I have a new 24 inch iMac that has the 1066 front bus. However, the computer came with ddr2 memory running 800 hz, Can I switch these memory chip to ddr3 running 1066 Hz? I just wanted to make sure before I did it!
Thanks for a quick answer.
Despite the speed of you systems frontside bus, the RAM you can use is limited to what type of RAM slots you have. DDR2 RAM and DDR3 RAM are not interchangeable and unfortunately there in no way to use the faster RAM in your system.
RAM speed should not be too much of a concern though. Your RAM is not the slowest part of your system, the hard drive is. Look at upgrading to a Solid State Drive (SSD) to see noticeable performance increases.
