Upgrading RAM: Quick Question

[VoltronBomb]

So I just got a new MBP 13" and I want to upgrade its RAM from 4gb to 8gb.

My question is: Do I need to buy a 8gb RAM kit (Two 4gb pieces) or would I be able to buy one 4gb piece and install it to add to the existing 4gb?

I have checked various websites looking for this answer but none have provided me with one.

Normally stock 4GB RAM configurations are 2 x 2GB chips, so you can either buy one 4GB chip and go to 6GB or buy two 4GB chips and go to 8GB.

That makes total sense now. Thank you very much for the reply!

Your MBP only has two RAM slots, which are filled with 2x2GB, if it came from Apple with 4GB. You would replace those with 2x4GB to upgrade to 8GB.

• Apple does not manufacture RAM and charges more than you would pay with other reputable RAM providers.
• Some great sources for Mac-compatible RAM are OWC, Crucial and newegg.com.
• Installation of user-installable parts such as RAM does not void the Apple Warranty or the AppleCare Protection Plan, unless you damage something in the process.

You can find specs on all Apple products, including maximum RAM:

• By visiting EveryMac.com: Actual Maximum RAM
• By selecting your model on the Crucial Memory Advisor™ Tool to find RAM information
• By using Mactracker
• By entering your serial number here to find specs for your model.
  (Be aware that some models can use more RAM than Apple shows. Check EveryMac to verify actual usable RAM.)
