Installing Additional Memory
Your	computer	has	two	memory	slots	that	you	access	by	removing	the	bottom	case. 	
Your	MacBook	comes	with	a	minimum	of	2	gigabytes	(GB)	of	1066	MHz	Double	Data	
Rate	(DDR3)	Synchronous	Dynamic	Random-Access	Memory	(SDRAM)	installed. 	Both	
memory	slots	can	accept	an	SDRAM	module	that	meets	the	following	specifications:
	
ÂDouble	Data	Rate	Small	Outline	Dual	Inline	Memory	Module	(DDR3)	format
	
Â30	mm	(1.18	inches)
	
Â204-pin
	
Â1	GB	or	2	GB
	
ÂPC3-8500	DDR3	SO-DIMM	1066	MHz	 Type	RAM
You	can	add	two	2	GB	memory	modules	for	a	maximum	of	4	GB	of	memory. 	For	
best	performance, 	fill	both	memory	slots	and	install	an	identical	memory	module	
in	each	slot. 	
To install memory in your MacBook: 
1  Follow	steps	1	through	3	beginning	on	page	37.
Important:  When	you	remove	the	bottom	case, 	you	expose	sensitive	internal	
components. 	Avoid	touching	anything	other	than	the	memory	assembly	when	you	
remove	or	add	memory.

the	module	from	the	memory	card	slot. 	
The	memory	pops	up	at	an	angle. 	Before	removing	it,	make	sure	you	see	the	
semicircular	notches. 	If	you	don’t,	try	pushing	the	levers	outward	again.

Important:  Hold	the	memory	modules	by	their	edges, 	and	do	not	touch	the	gold	
connectors.
5  Insert	the	new	memory	module	in	the	slot:
a Align	the	notch	on	the	gold	edge	of	the	module	with	the	notch	in	the	lower	
memory	slot.
b  Tilt	the	card	and	push	the	memory	into	the	slot.
c  Use	two	fingers	with	firm, 	even	pressure	to	push	down	on	the	memory	module. 	
You	should	hear	a	click	when	the	memory	is	inserted	correctly.
d  Repeat	to	install	an	additional	memory	module	in	the	top	slot. 	Press	down	on	the

Making Sure Your MacBook Recognizes the New Memory
After	installing	additional	memory	in	your	MacBook, 	check	whether	the	computer	
recognizes	the	new	memory. 	
To check the computer’s memory:
1  Start	up	your	MacBook.
2  When	you	see	the	Mac	OS	X	desktop, 	choose	Apple	()	>	About	This	Mac.	For	
a	detailed	breakdown	of	the	memory	installed	in	your	computer, 	open	System	
Information	by	clicking	More	Info, 	and	then	click	Memory.	
If	your	MacBook	doesn’t	recognize	the	memory	or	doesn’t	start	up	correctly, 		
confirm	that	the	memory	you	installed	is	compatible	with	your	MacBook	and	that		
it’s	installed	correctly.
