Does it make sense to put more than 3 Gig RAM in a Vista computer ?

Somewhere I read that it does not make sense to put more than 3 Gig RAM in a Vista computer since Vista will never use more available RAM than 3 Gig ... ?!

 

Did you also read someplace that VIsta comes in two versions, 32 bit and 64 bit? The 64 bit will accept more than 128 GB of RAM. The 32 bit will recognise between 3 to 3.5 GB depending on shared memory.

 

also dependant on application running...most users of CAD and the like have prefered more then 3G and usually opt to max out the RAM anyway.

 

Unless you disable Superfetch, Vista always use all available RAM to preload files it thinks you may need.

That's why, even on my desktop with 8GB for example, Task Manager indicates 32 KB free and around 4000 KB allocated to cache and another 4GB or so used by apps.

 

that is vista 64 bit right ? 32 will not see or use more than 3.5 gb tops . i'm running 6gb now , 8 as soon as the other 4 get here

 

lol, it depends on a case-by-case basis.

 

you have vista 32 bit using more than 3.5gb ,memory ? I could never get it to do that

 

If you have a desktop sitting around and you can install a graphics card with a relatively smaller amount of memory (128 MB or so) and limit the aperture appropriately, you can utilize more than 3.5GB.

 

Not possible. This is not true.

 

afaik it's true, though you can't use more than 4GB on 32 bit system. so in this way you can use more than 3.5 GB but less than 4GB

and 64 bit system allows you to use 16 Exabytes of memory

 

It's completely possible, mate.

This is true.

 

I can back up my arguments, but can you? I still don't buy it. Not even with a 64 MB GC. There are plenty of components needing the upper memory. A 4GB capable computer will not allow you more than 3.5 GB on a 32 bit OS.

 

This is assuming those components requiring membership in the address space exist. These components don't always exist on all systems. My statement assumed nothing other than a video card, so it holds true.

Understanding Address Spaces and the 4GB Limit.

 

You are sugar coating it. You won't be able to do work with the system you have in mind. Come up with a feasible system and not some crippled thing which will never give you more than 3.5 GB. A 32 bit OS won't give it. Not even with a 36bit PAE switch.

Google what the limits of a 32 bit OS are...If I want fairy tales, I will read a book...


P.S. The article you posted is trash. I've known about for quite some time.

 

Again, Understanding Address Spaces and the 4GB Limit. This article highlights a few systems that are fully functional.

Get to reading then, I suppose. A hard 3.5GB limit on all 32-bit systems is a fairy tale.

I think this effectively shreds your credibility in this discussion.

 

I think we've got different ideas what a system is. You are talking about one where Paint is the heaviest app and the most complex photo editor, I am talking about one where Photoshop CS4 is a main editor.


Furthermore, the rule should apply to all systems not to some crippled things nobody uses. How is that helping someone without being able to simulate the rubbish system from the article?

4GB? Go x64!

It is still a piece of bull. I tried every thing out there, and the article you mentioned was the first thing I read in december. My Asus had huge memory fluctuations between 2.5 et 3.5 GB. Photoshop was reporting less than 3GB memory. MY REAL MEMORY!

So, post those fairy tales to kiddies.


I also went 320 km/h with my Scooter pulled by a Ferrari. Following your logic, there are scooters out there going 320 km/h.

 

Okay how about this. A 32bit OS will use LESS than 4gb of ram. A 64bit OS will use as much ram as money can buy (for now).

There

 

And, how does this apply to address spaces? It's true a system with a higher amount of video memory will have less addressable space left over for RAM to be mapped. What point are you trying to make? All I did was prove that 3.5GB is not the memory limit for all 32-bit systems. Said systems are fully functional, as well.

How exactly were those crippled systems?

You're making absolutely no sense. How does this apply to the discussion?

 

This thread has deteriorated into bickering and its now closed.

Good way to put it.
