No, I am not saying that at all.


You have a non-server 32-bit Windows. The maximum number of memory addresses are 4GB worth. However, some of those addresses are reserved for devices, I/O, legacy, ect. That means at very most, you can have up to ~3.5GB usable by the OS. However, your video cards require a large number of I/O addresses as well.... therefore, your OS will probably only allow 2.8-3.2GB of usable memory.

Adding another 1GB won't do much as it will not be usable by the OS. The only thing you could do is create a RAMDisk.

No.... You do not subtract the video card's memory. You subtract the memory addresses the video card requires to communicate with OS. You can find this under Device Manager.

It would be 3GB avaliable to the OS (video card, legacy, and other devices already reside in the 1GB of address above the 3GB). This is assuming OP does have 3GB avaliable.

This means most 32-bit games would use up to 2GB leaving 1GB for the OS and other apps (while gaming, of course.)

It's abit problematic since I will have to dump the Blacklines and get a whole new set of >=6GB memory and it's pretty expensive here... atleast $200 I suppose.

You could overclock what you have a bit if its an issue.

I understand it now. I never planned on adding 1GB cuz It would be like adding 0 to 256MB Maximum of RAM. Useless. As I said before, I wanna get >=6GB of RAM and my only problem is budget.

It's overclocked to 2000MHz. It's not necesarilly an Issue, I just need to know where I'm standing in order to plan future upgrades efficiently and be able to prioritize the upgrades correctly

Ram is cheap right now... it may be a good idea to buy. I would if I had the money (and a system to make sure it works)

I need to relearn this then.

Lol, I'd get more RAM too if I had the $$$. Guess I'll have to look into some good DDR3 sticks over here to see if I have the money

Wait so you have 3gb, or you have 4gb and your OS just won't recognize it because it is 32 bit? If so then the problem should be simple, get a 64bit OS.

If it is 3gb in triple channel then you should get 6gb of fast ram, at least 1600mhz which you should be able to find on sale for under 100$. (then maybe overclock it a bit too.)

You probably wont use all of it now but for me having 4gb I do approach 4gb its when running games like WoW and SC2 in Fullscreen Windowed, while having multiple programs and web browser windows open on my second screen.

The OS will also recognize you have more ram and change how much ram it uses. Windows 7 Ultimate on my netbook with 1gb ram uses considerably less ram then my main computer with 4gb even on idol.

So don't let people tell you there is no need for more then 4gb of ram, 6gb may be overkill a bit now but I really don't think you will regret it. Just don't go out and buy 12gb or 24gb packs, that would be overkill.

I have a triple-kit 3GB. I dont plan on getting 12GB lol but I have been looking around 6GB-8GB kits. Problem is I must buy it from a store over here (not abroad) and so It will be more expensive than you might think. Any recommended kits? >=1600MHz ?

No point investing in ram for gaming.
6gb ram means you'll have to invest in 64 bit OS too.
Crysis with loaded level and played 30min + hd movie + winamp + chrome with few tabs + some crap and i didn't get full 3gb usage.
