2013 iMac Memory Help

Download the crucial system checker from their website. Run it and find out what is exactly compatible. Then shop elsewhere for a cheaper price.

When it comes to Macs they can be temperamental with clock speeds so only use what's recommended and match whatever is already in the system.

As for brand names like vengeance and all that *****. It's just marketing nonsense. Ram is Ram and don't for one second let anyone tell you otherwise, it's simply rebranded factory Ram in order to give system builders bragging rights. You'll get hardcore performance nuts arguing that different brands of ram make a difference but to be honest you'd never notice it in a million years.

Just make sure whatever you buy has got a good return policy and warranty, Ram can go bad or be faulty but it doesn't happen too often.

 

• Memory modules get finicky and may not function properly when under clocked.
• 2133MHz CL11 memory at 1600MHz will be slower than 1600MHz CL9 memory in that same system.
• And finally your Mac expects memory modules to fall within a certain spec range - if you get memory that falls outside that range you may have issues.
