previously my vista ultimate just support 3gb for my 4GB installed but after i download the latest window updates then it's display 4GB already, i not sure is it fully run 4GB or not.

does anyone same case with my pc ?

ve u gone thru the thread???

as long as u re using Vista x86, or any other 32-bits OS, it will NEVER use 4GB...

Vista x86 SP1, however, will show the amount that sits in the computer, not the amount that Vista can use...

fire up task manager and u'll see it's not 4GB...

My answer is just a simple-one-liner. 4GB is displayed but only 3GB++ is utilized.

overall, if we want to used up all the ram that we pay upgrade to vista 64bit, and loose some of 32bit app.

anywhere in the world there will be trade and balance , we cant have it all my fellow lyn'rs

Guy...i'm figure out a problem when slotting 1gb RAM into my lappy. Existing RAM is 2gb. But when i'm slotting one more 1gb RAM, it show error on window during booting.

What exactly happen...any idea?? Last time i checked at crucial.com, it say that my lappy can go into 3gb ~ 3.5gb of RAM max.

Mine is Presario C767TU

p/s: i had post it in others thread too. But i'm still not satisfied with the answer. So decided to ask here.

Make sure that you match the correct specs of both sticks of RAM.

Sorry to ask but does this problem also affect 2gb of ram. Mine has 4* 512MB of ram but it only detects 1.5gb. Always thought it was a Mobo problem, running vista 32 bit on and AMD athlon64 3200+ system

lynxs, the missing 512MB is allocated to the onboard VGA

really? but i have an abit AV8 mobo, which does not have an onboard vga.

patutlah aku tgk kat pc aku 3gb ram jer.. adoiyaii

wanna change my vista to 64 bit at future. i love the other 1gb missing.

Haha..Juz changed my vista ultimate to 64bit...4GB shown...

how do you feel? faster or same as before?

It's same...Juz giving more memory...

i'll think twice for changing it..

Why? lazy to backup the important files before format?

Some people do upgrade because they want better performance. Since our ppl feel it was just the same as before... May be that upgrading can be skip for a while...

there's no harm done using XP x64 or Vista x64, ok... apart from getting the driver which is used to be quite hard -- but now, i think should'nt be a problem

Check your task manager @ Total Physical Memory, how much?

that's one of the reason..the other is u said it not too much different..
just adding some memory..
