Main differences between 2GB and 4GB of RAM

What are the big differences between 2GB of RAM and 4GB of RAM?

Is it only noticeable in gaming?

the more mem you have the less your pc has to access your hdd (mem is faster than an hdd) so things should work a bit better

Well, if you have Windows Vista or 7 you will experience a lot less HDD activity. This not only guarantees a longer life of the HDD, your OS will be faster and more smooth. But beyond that 4GB it is only measurable in RAM intensive tasks.

What about OS X? I was looking at the Macbook and the Macbook Pro.

Generally, the sweet spot nowadays in terms of how much RAM you should have is around 4 GB. More is overkill, at least right now, and less can potentially be a bottleneck with some apps. (games included) So I'd say just get 4 GB of RAM and be happy.

Agreed, 4GB is pretty enough right now, but may change when XP gets less supported by game developers.

If you decide on 4GB or more, do get 64bit Win7/Vista, I used to play lotsa games on my 4GB 64bit Vista HP system and it was more than sufficient.

Two GB is just going to harm any gaming experience you want to have on a computer with Vista or 7. Two GB just isn't enough these days for modern games. Modern games can take up one GB or more of RAM and with Vista, you run out fast considering Vista can take up one GB by itself.

For decent gaming experience, I say decent because you have to have a nice CPU and GPU as well, you'll want at least four GB of RAM. This leaves plenty of room for the OS and not have to worry about the computer using virtual RAM, aka the page file, aka the hard drive. Virtual ram slows down any type of computer use when the computer has to use it since the hard drive is the slowest part of the computer.

2GB is still good these days. 4GB is just better. I still use 2GB and i have no problems.

Virtual ram slows down any type of computer use when the computer has to use it since the hard drive is the slowest part of the computer.
Vista and Windows 7 both take up less then 500MB of RAM, it is the SuperFetch and similar technology that consumes excessive amounts of RAM on these operating systems and when a game or program requests memory occupied by these features, the O/S will free the RAM. (info @ http://arstechnica.com/microsoft/new...emongering.ars)

When looking at Physical Memory (RAM) in Task Manager under Windows 7, look at the "Available" total rather then the "Free" total. For Vista users, combine the "Cache" and "Free" values in Task Manager to work out the amount of memory you have free.




Now as for 4 gigabytes of RAM Vs. 2, you will encounter less stutter/pauses during games which load new areas or character models/graphics as you explore as well as less loading times in games that explicitly have a loading screen for each area of the game.

Games like Dragon Age, Starcraft 2, Settlers 7, Settlers II 10th anniversary edition, Black & White 2, Need For Speed: Most Wanted (and newer), Command & Conquer 3 and Red Alert 3 are just some examples of games using more then 2 gigabytes of RAM if available.

You can also include most modern (within the past 8 years) FPS, RPG and Racing Simulation games.

As mentioned, 4GB is about the sweet spot for most systems. gaming Rigs included.

Look at it like this:

Win7 x64 will use, on average, about 1GB of RAM at idle.
the majority of Games are 32bit, and can have 2GB allocated to them for use.

4GB of RAM will allow the game to have access to the full 2GB they can use, without cutting into anything the OS is using with a bit to spare.

If a game is address aware or 64bit, it will be able to use more memory than the 2GB cap if needed.


Depending what else you use your PC for, other than gaming, more than 4GB of RAm can be quite useful.

But, ONLY IF, you run Multiple Virtual machines, do a lot of Heavy Photo Shop Work, or a lot of heavy HD video encoding (1080P material) 6-8GB of RAM will be a huge benefit.

If you do NOT do a lot of these things mentioned, more than 4GB RAM would truly be a waste for you.

It also increases the footprint Windows can use, speeding everything up slightly. Although this isnt a huge difference.

With 8GB of RAM, my machine often uses 2-2.25GB of RAM at IDLE, with the remainder in Standby Mode leaving 0 free RAM.

A bit off topic but, Remember,
In USE = what currently being used

STANDBY= RAM that has things loaded you may use soon, or have used earlier. This can be dumped of more memory is needed very quickly.

FREE = unused RAM.... FREE RAM is bad, as its not being used for anything.

0 Free is ideal.

4GB give a little extra headroom for Windows to fill up. Meaning everything will be smoother overall.
