Memory for your Mac

It might have seemed back when you bought your MacBook you thought that 4GB of RAM was going to cut it. Now that you've hit your performance limit and want enhanced turnaround without the hassle of removable hard drives or USB thumb sticks, getting additional Mac RAM installed can have your system running like a pro again.

Usually a Macbook Pro will give you two slots for additional memory and various other machines like the Mini and PowerMac may have explicit preferences, so optimizing this space is crucial. When shopping for upgrades, look for models that offer heat spreaders and lower tRas values. These features mean lower likelihood of overheating if you try to further modify your Mac, and even if you leave your Mac RAM as the manufacturer intended, a low tRas means faster operating speeds. Also, Macbook Pro owners should watch out for XMP-restricted RAM - this stuff will only function at 1333MHz, so you may not want to pay more for something that doesn't work the way you want it to. With the right tweaking, you can get your laptop functioning almost at the same capacity as a desktop model without spending nearly the same amount of money.

For optimal output and performance make sure you check first and see what kind of memory your Mac uses. For every kind of Apple product there are corresponding limits on the amount and kinds of memory that will work for your machine, and it's important not to damage your computer in the process of upgrading. Optimal setups will run at 1600MHz but be aware that you can scale this down to get larger amounts of Mac RAM without sacrificing functionality.
