Upgrading RAM on Late '09 iMac (1 Viewer)

[Heathen Saint]

I have a late 2009 iMac, 21.5", 3.06ghz intel core 2 duo with a measly 4 GB 1067 Mhz DDR3 ram (i bought it used a few years ago for like $250). As you can guess, processes are very bogged down.

Anyway, i'm on MacSales.com wanting to upgrade my RAM with some OWC chips. I was wondering if it would be better to upgrade all 4 memory slots (4 gb each) for a total of 16 gb memory, which is the limit for this model--or if I should just go with two 4gb for the two open slots i have available. I suppose what i'm asking is if it will really make a huge difference in tasks from 12 gb to 16...

Definitely better to have the same RAM in all 4 slots.

Awesome, I'll go that route. Thanks!

Has this improved hthe computer at all? I have an early 2009 iMac with 4gb and I am debating upgrading to 8gb(only 2 slots). The computer is now 8 years old and runs really hot so I'm nervous it may die soon and upgrading it would be worthless. But then again a new computer is expensive

It's a teeny bit quicker but nothing substantial that i've noticed. It's quick enough but a good bit slower than my 2013 MBP 16gb ram i7
