^ both are good. for most applications 4gb is enough

I don't know which I should take. And 4GB memory is more the enough or enough only?

Should be said enough use for normal user. As mine sometimes run out of RAM when I'm on alot of program such as iTunes, iMovie, iPhoto, photoshop and etc together. If you're not using those heavy software together at the same time then it's more than enough.

last time i only have 2gb. can say okayyy la wanna run parallels n win7, but sometimes lag abit. very seldom

now 4gb, no lag obviously it depends what u wanna do lah. u can juz get parallels n install win7 1st.. if u feel lag, then upgrade ur RAM lah

act,what is the difference between KTA n KVR ram?
anyone can explain?
thanks.

Multitasking. But wonder I need to buy 4GB or 4GB(x2) coz planning for future upgrading if not enough memory but single channel good?

i dunno what are the technical differences but if i have to guess, KTA uses better quality chips. KTA are tested for macs too, so they work perfectly. KVR is more of a gamble, they may or may not work

if u have the money, juz go for 2x4gb

where can we get branded ram modules that are compatible with MBP ? thinking to get 2x4GB but not very convinced by people that are using the normal kingston value rams..

then you can just get Kingston KTA RAM

how many GB ram macbook can support?

depends, what model?

4GB.

went ahead and upgraded my MBP 2009 to 8GB.. KVR rams with hynix chip

guys.
Just now I talk to my local apple authorized reseller's boss.
he say must use apple certified ram because of watt and blablabla.
is that true?

Xirality : if you can't understand what he's talking about, why are you listening to him?

you can use ANY RAM that matches your spec. the risk with non-certified RAM is that in sleep mode (when you close the lid of a portable Mac) ... you might suffer a system hang / crash. my suggestion is simply save everything before shutting the lid. so even if it crashes, you'll lose no data.

if that is not an acceptable risk for you, then go ahead n buy the certified RAM.

that guy was spewing bull. if apple uses proprietary RAMs, they would be much much much much more expensive. certified RAM simply means they are guaranteed to work. non-certified RAMs often work anyway

just when ahead and upgrade my mbp 2009 to 5gb ram.

KVR1066D3S7/4G 1066MHz PC3-8500, 1066MHz CL7- rm245

like what calvin did. absolute satisfied xD now i can fully utilized premiere pro.

okay.
btw, i normally use itunes,adium,tweetdeck,safari(3 tab +/-),cs5.
how much ram i need?

depends on the size of the file u work on in cs5. 2gb shud be enough for small files

How much and where you bought? Kingston?
MBP13" running on 2GB..very lag play SC2, check the default graphic setting all were set the LOWEST setting !!!
Im wondering 4GB is enough or not or 8GB works far more better?


I thought to perform better performance, both RAM recommend to have same capacity (MegaByte)?
