Hey All

As you can see still kinda new round here and still trying to get my head around RAM so i was just wondering would having 5Gb of RAM (2x2GB 1x1GB) in my mac pro make it run slower than just running say 2x2GB?? or in general on a normal pc would this be not advisable??

If it's able to run 5GB then it shouldn't affect performance at all (noticeably).

4GB is usually enough for the average user, what are you doing on your Mac, if it's video rendering etc then I'd definitely add more RAM.

always match ram to remove any headaches later on

ahh sweet thanks for that. yeah i got it second hand so it came with 5GB for some reason lol didnt really think to much of it at the time but as i been reading more lately wasnt sure so thought i'd ask.
As i use it for video editing and such ive been lookin at getting some more RAM and was thinking 12GB should do? any comments on the type?

g skill is all I use. I had corsair in a build and it couldnt hit spec without massive voltage, being as you have a laptop make sure when upgrading you get exactly what the computer is built for and nothing under. Also, be hesitent about getting something over (in mhz) because you cant clock it up if the computer doesnt support it.

Most Mac's require ram to be installed in parity. here is a guide that will show you which DIMM's need to be populated and in which order

Of course, if the Mac isn't 64bit, there's just no point in having more then 4gigs of RAM.

brkbeatjunkie

thats not true at all.
let me show you. I have mac os 10.5, Not Snow Leopard. My Mac was made in late 2005 and accepts a max of 8gb

Then you're running the 64bit version of OS 10. It's not some software limit, 32bit can only read 4gigs max.

Only Windows is effected by the 3.5 GB limit. UNIX had fixed this problem years and years ago
