When it comes to computers it can impact proformance of up to 27% if you use programs that heavily use memory, games for instance. You can still go both ways but you have to wait for the other car to pass before you can go the other way. Single channel is like a 2 lane road with one lane closed off. When you are running Dual channel both lanes are open, traffic is running smoothly
In your case your laptop can run in what is known as Dual-Channel and Single channel ram configuration.ĭual channel is when you have 2 sticks of ram with identicle size (Speed really doesn't effect the avalability of dual channel), single channel is when you have either 1 stick of ram or 2 sticks that are different size. Which is a whole other world of explaination. However if you put a 4GB stick and a 2GB stick in you will lose what is known as Dual channel.

OWC has a blog post Certain 2010 MacBook, MacBook Pro, and Mac mini models join the ’16GB’ MaxRAM club going into more detail. If you have 1 stick of 4GB DDR3 8500 and an other stick of 4GB DDR3 12800 the computer will notice the difference and lower the faster ram down to that of the slower ram. An alternative is to use one 8 GB PC3-10600 module along with a 4 GB PC3-8500 module for a total of 12 GB, but there would probably be a speed penalty from having mismatched module sizes. Unless you are using this laptop for gaming, or scientific calculation you will not see a vast difference between 850.Īlso you can mix and match DDR3 that have difference speed ratings. The numbers simply mean how many MB per second they will top out at. However you will not see any improvement with system speed. The fastest memory that your laptop can use is DDR3 10600. It use to be easier 15 years ago when there weren't so many options available. With the given 1-year warranty, this gives you a total warranty of 3 years.I do understand your confustion.
