I have iMac Mid 2010, 3.6 GHz Intel Core i5, 21.5-inch
Currently i have 4x2GB = 8GB @1333Mhz.
I have bought 4x4GB =16GB Corsair memory @1066Mhz. (Thanks giving deal)
Just wondering is there any speed difference which will i see.... ?
Most of the time i use photoshop (adobe), Audio editing and video editing softwares (FinalCut, iMove, etc...) and day long browsing.
after installing 16GB @1066Mhz, i see the reduced score on geek bench .. but when i use my iMac it feels faster!! im kind of confused to keep the 16GB memory or return it.... Please help me .... can you please explain what is the difference and should i keep the 16GB memory or not.
People are giving me different opinions on this, but i love to hear from you. Please explain me in layman language :)
Please see below results with geek bench.
with 8GB ram @1333Mhz
And here i installed 16GB@1066Mhz of ram and did the same test
Well the actual speed of the memory is not always that important, depending on your task the CL latency might be more important. If the 1333MHZ RAM you had from the start came stock with the computer it's pretty terrible RAM, sure it's 1333 but it has way higher latency than a good Corsair stick. Also more RAM means things will run more smoothly, not needing to cache the HDD is a huge performance improvement. When using number crunching programs such as editing you will benefit more from a lower latency than higher clock speed, however if you want to load programs faster you will benefit more from higher clock speeds, to simplify things that is. Pretty much every branded RAM stick will be better than a mac stock RAM stick because they are fairly terrible. Also the 1333 sticks might run at lower speeds and they only get multiplied up to 1333 while really they run at 667. If it feels faster with the 1066MHz then go with it. I wouldn't consider buying faster RAM because the motherboard doesn't support faster than 1333MHZ.

You wont notice a difference in performance, even with most benchmarks, the memory speed does not make much of a difference. This is due to most tasks especially those done by most consumers, are not memory bandwidth intensive.
While slower speeds are not ideal, in this case, you most likely wont notice any slowdown, the additional memory will on the other hand, will improve performance.
The reason why your score went down is due to the lower memory score, but trust me, it wont translate into lower performance for the apps you run unless they are memory bandwidth intensive (which very few are)
