kennmeng, as posted up above .. upgrading RAM yourself won't void the warranty unless you damage your macbook while upgrading, then .. it is totally different story. Upgrading RAM most probably the most non-brainer thing that you could do on your MB.

funny, running on 4gb now, dun really feel anything

I upgraded mine from 2GB to 3GB (max for my MBP old version) .. doesn't feel any different either.. probably, my current load doesn't really need me to have that much RAM ..

is it expensive upgrade to 4GB ram for de price RM300??or i can get abit more cheaper?

my macbook pro using transcends apple certify Ram 2x2GB (DDR667)..very smooth on all app. best of all very reasonable price (i get fr my supplier)

i never buy Ram at mac shop..they price is sky hi

b4 this use kingston value ram..unstable

Anyone using this DDR3 RAM by Micro Memory Bank from US?
Just got it 2x2GB from eBay and now waiting for it to arrive.

Will update as soon as I try it out.

ah blu, berapa?

geez
i wanna upgrad my ram too

i change my ram to 4gb, but when i check at "about this mac" it shown 3gb only, curious!!

old version macbook only support up to 3Gb...
my friends's macbook manufactured 2007(Mac) only can support up to 3gb..
mine one bought mid of 2008 can support up to 4gb..
if im not mistake december 2007 and later only can support up to 4 gb.

@rx330, 52USD for the RAM itself + 16USD international shipping.
Should be around 250RM in total then.

Will there any tax from customs?

btw, these rams are 1066MHz right?

@jims2005, yes DDR3 1066, I'm not sure about the custom tax in Malaysia, but here in Germany I suppose it will be released without tax. Once I heard custom only tax for item more than 100USD. Not sure it's true or not.

I using same as blu brought and i got problem on my macbook stuck on wake up after sleep..

esssymanex, oh my god, are you sure? then wat RAM are u using now?

Same as you just brought. I ordered it on OWC Ram. It given me same ram in ur picture and also US maker Micron Chip. Now, i just disable the sleep mode and working properly but sometime it freeze suddenly. Huhu...

like i use kingston value ram b4..will freeze suddenly..guess this a bad ram sign

Oh my god... *biting finger nails + sweating*... nightmare! My RAM still not yet arrive. Let's pray it run without any hiccup then...

Anyway, esssymanex, cannot ask for refund or exchange? Since it is lifetime warranty...

I was thinking about the shipping back cost about Rm 140.00. Since then, better i used it. It very rare freeze up but notice if you do sleep the macbook for long hours, normally turn to freeze.

is that necessary to use only the Apple certified RAM module? Can a normal Kingston/Corsair SO-DIMM work well?
