Okay, check this out. I recently picked up my new iMac (specs in sig) and I immediately ran a Geekbench run just to see what it would do. It showed something like 3983 on the stock 2GB DDR 800 memory. I then swapped out the 2GB DDR 800 memory for 4GB DDR 667 memory that I had in my MacBook Pro. I then ran the Geekbench test again and this time my score went down to like 3800. Why in the world would the score go down instead of up? could it be because the stock memory is running at a faster BUS speed than what my laptop memory (DDR 667) was running at? if so, what should I do? should I put the stock DDR 800 memory back in or just keep the 4GB of DDR 667 in and be happy with that?
