if you want to improve gaming performance, try selling ur MBP 13 and get the MBP 15 u'll want a better GPU

RAM upgrades doesnt help much for gaming, 4gb is a lot already for games. RAM only helps you to do more things at once, it's doesnt improve performance of any single program by much. unless, for some reason, you want to run 3/4 games at the same time, i suggest you spend ur money on something else.

probably a better mouse or bigger external display?

^ it's still a new drive. juz announced last month or last 2 months. dats y very hard to find

ermmm im pretty sure we use unbuffered RAM. afaik only Mac Pro uses buffered RAM.

may i ask where u order?

i didnt need a handbook to install my RAM hehe... very easy one.. juz make sure u have the right screwdrivers

that's the thing about RAMs... except for apple's, OWC n crucial... no 100% way to be sure ur RAM will work or not

should be around 1000-1200 like that

can u specify which part of the start up is slow?
- blank grey screen
- grey screen with apple logo
- plain blue screen
- already logged in but still unresponsive
- all of the above?

if OWC say 8gb is compatible then it probably is. like my MBP 5,1..apple say max is 4gb only. but OWC claimed 6gb no problem

u're looking for 1333mhz for the latest iMac am i right? cuz it wont bring any good on MBPs n older 1066mhz imacs

i'd stick with the top brands if i were you. not saying kingmax is not good lah, but the price wont differ much anyway

ur 4gb is actually a pair of 2gb sticks, n u only have two slots. u can either remove one 2gb stick n put it one 4gb stick, or remove both 2gb sticks n get a pair of 4gb sticks

corsair, OWC, crucial, ori apple RAM, kingston KTA <- reportedly these works best

RAM can DIY n wont void ur warranty

if u're supposed to use 1066 but u use 1333, ur machine will just downclock it to 1066. meaning 1333 RAM will work, but no point of spending extra money for it since it'll perform just like a 1066 one.

welcome. no software/driver installation needed

^ both are good. for most applications 4gb is 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

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

depends, what model?

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

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

integrated GPU what.... 9400M is good but not that good

i dun think a RAM upgrade would help much

it works for u doesnt mean it works for evryone hehe

but good for u!
