hardware performance

So much ignorance.

I hate tech myths.

@Arda Are you sure you're right about that?

@Fabian I linked MSDN.

Which mentions the 2GB limit in "User-mode virtual address space for each 32-bit process"

Also in kernel-mode.

Additionally, on the page for 4 GT (an advanced feature not enabled on most installs)

> On 32-bit editions of Windows, applications have 4 gigabyte (GB) of virtual address space available. The virtual address space is divided so that 2 GB is available to the application and the other 2 GB is available only to the system.

The 32-bit versions of Windows are able to address 232 bytes (4 GB) of memory by default. Windows splits that memory, allocating 2 GB of memory to the kernel and up to 2 GB of memory to each application’s private address space.

from the same page

5:37 PM

Exactly.

2 GB to the kernel means only 2 GB left for applications.

That says 2GB per application

Then, where do you suppose the rest comes from?

You have 4 GB total available.

2 GB is subtracted and given to the kernel.

That is all virtuall adress space, every app gets its own

You only have 2 GB left to work with.

Every application gets 2 GB, that is true.

But all the applications together can't exceed 2 GB, because the other 2 GB is assigned to the kernel.

From the page: Each application can also utilize up to 2 GB of memory. This is true regardless of the number of applications on the server and despite the operating system’s ability to natively recognize only 4 GB of total memory.

5:39 PM

Well, yes, but each application cannot utilise more memory than there is available.

Otherwise I'd like to give Photoshop 1 TB of memory whenever I use it.

But there is more available, everything we're talking about is virtual address space

Again, 2 GB is allocated by the kernel

There is no way for an application to touch that part of the RAM

Yes, but every application gets 2GB for itself

2GB of virtual address space does not mean that the kernel uses 2GB of real memory

@Fabian Aye. If it uses up those 2 GB, then RAM utilization goes up to 100%

@Fabian It may not use it, but it does allocate it.

(By the way, starting with Vista, it does)

SuperFetch fills all available kernel-mode RAM with frequently accessed files.

But that is only virtual address space, and there is an essentially unlimited amount of that avaiable

5:43 PM

@Fabian Theoretically, but not enough addresses.

Every process gets 4GB, of which 2GB are reserved for the kernel.

The CPU can't differentiate between kernel and user-mode addresses.

You don't get separate addresses for both.

@Fabian No, every instance of Windows gets that.

Windows gets 4 GB, 2 GB is allocated to kernel-mode, 2 GB to user-mode.

Each application can also utilize up to 2 GB of memory. This is true regardless of the number of applications on the server and despite the operating system’s ability to natively recognize only 4 GB of total memory. If the total memory requirements of all applications exceed 4 GB, the memory manager uses a paging file to substitute for RAM. This process is described in the following paragraphs.

That is from the 4GT page

@Fabian Well, yes, of course.

You can always use paging.

(Which, by the way, is also limited to 2 GB.)

> Windows Vista and above: Limited only by kernel mode virtual address space. Starting with Windows Vista with Service Pack 1 (SP1), the paged pool can also be limited by the PagedPoolLimit registry key value.

Q: My Gaming open id is not being associated with my other stackexchange accounts, is this expected?

For some reason, my gaming open id is not being picked up with stackexchange and associated with my other accounts. Is this because the site is special or something or is this a bug? Or did I do something wrong?

5:47 PM

I'm pretty sure you're wrong, but that question has probably been asked somewhere on SE

We're talking about physical RAM.

Do you have any experience with Assembly?

No

Well, I'll try to explain. Basically, on the lowest level, this is how it works.

The OS talks to the CPU directly, using instructions like give this bit this value.

RAM is like an array of bits.

The array is referenced with numbers, like an array in Java or whatever is.

But in our case it is an array for each process

No.

That's the point. The CPU has no concept of processes.

5:51 PM

We're talking about virtual address space

I'm not.

I'm talking about the CPU.

But the 2GB kernel memory is in the virtual address space

And the reason why memory is limited to a certain value (4 GB in 32-bit, 8 TB in 64-bit).

Could you please stop assuming Windows? I'm talking about CPUs in general.

Processes are an abstraction made on the OS level. The processor has no concept of processes.

All it knows is instructions.

So, as I was saying, RAM is accessed in assembly with something like RAM[index].

Except in order to provide the CPU with this index, it too has memory.

On a 32-bit CPU, this memory can store integers between 0 and 4294967295.

4294967295 bytes is 4 gigabytes.

So, it is impossible to access any bytes beyond the 4294967295th, because it's impossible to tell the CPU give me the value of byte 4294967296

The CPU can only count to 4294967295.

Check this MSDN blog: blogs.msdn.com/b/oldnewthing/archive/2004/08/09/211356.aspx

False.

Well, true in a way.

But irrelevant.

Of that 3 GB, a maximum of 2GB is on the RAM.

The other GB is in the paging file.

There is no way for any OS to access more than 4 GB of memory on a 32-bit CPU. Period.

5:58 PM

But you claim 2GB

@Fabian I'm not claiming the OS cannot access only 2 GB of memory.

I'm claiming that Windows 32-bit can access 4 GB, and takes 2 GB for the kernel, leaving only 2 GB left.

But that all processes together can together only use 2GB?

Yes.

And that is not true

Basically, index 0 through 2147483647 is used by the kernel, and index 2147483648 through 4294967295 are usable by applications.

Every byte of RAM beyond that is in the paging file.

6:00 PM

The reserved memory for the kernel is just virtual address space, it is not all physical memory

Which is also limited by 2 GB for the same reason, giving applications a total of 4 GB of virtual memory, of which 2 GB is physical.

@Fabian Yes, it is. The 4GT article is about physical memory.

You are right, by the way, that I missed. 2 GB of paged, 2 GB of physical memory, for all applications.

I'm close to just opening a question on SU

I've written an OS before. I think I know how CPUs work.

(Which is, coincidentally, where these myths originate. People interpret articles wrongly because of assumptions of how OSes work.)

Q: Enchant blade in Magicka?

I've noticed in several Magicka videos that you can enchant your weapon with magic, but I must have missed that in the tutorial. How can I apply magic to my blade?

If I had a 32bit OS here I would just try it

6:09 PM

@Fabian How? You can't see whether an app is using physical or virtual memory.

By the way, if you want to test it so badly, try a 32-bit CPU in VirtualBox.

I've posted a question on superuser

Q: 2GB limit on 32bit operating systems

Does the 2GB limit on 32bit operating systems mean that each process can only access 2GB of memory, or that all processes together can only use 2GB in total. So, do the 2GB reserved for the kernel limit the total amount all processes together can use?

memory operating-systems

By the way, the answer is going to prove me wrong because you didn't specify physical memory, as I've been saying all along.

how should I rewrite it?

By specifying you're asking about physical memory only.

I'll answer it though.

I inserted physical memory there

@Fabian uuuh, wasn't the limit 4 GB?

@badp Please. Just... no.

Oh I see

Your answer goes over that

@badp Read my answer. If you still think that, read the last 10 minutes of chat.

The limit is 4 GB including paging. 2 GB of physical memory.

6:27 PM

I guess the bottom line is "disable swap"? :)

Here, have 10 reps.

5 reps for @Fabian too.

@badp Well, no.

You have 4 GB of memory including swap, in total. 2 GB per application.

Oh, by the way, the same answer on Gaming:

A: Does having more RAM beyond 4 gigs increase gaming performance at all?

Actually, yes. There are many misconceptions about the memory limit in 32-bit Windows OSes. First of all, when I say RAM, this includes every kind of RAM. So not just regular, but also your video RAM. The maximum available amount of RAM per process for a 32-bit OS is 2 GB. If you have a 64-bit ...

I cross-posted an answer on SE. How awesome is that?

@ArdaXi Question crossposting is generally frowned upon btw.

@ArdaXi Yes, so if I disable swap I can use as much RAM as possible.

Yes, but this isn't question crossposting. It's answer crossposting.

@badp No. You are limited to 2 GB of RAM in user-mode, whatever you do.

Swap just adds another 2 GB.

The OS doesn't run in user mode.

@badp All the applications do.

The other 2 GB is used by the kernel, for SuperFetch for example.

6:34 PM

Regardless, this means I can have 3 applications taking a GB each

and leave room for other stuff, all in RAM.

No.

You can't put 3 applications taking a GB each in 2 GB.

Why would the OS, which doesn't run in User mode, be limited by user mode.

The OS isn't 3 applications.

The OS has 2 GB for itself, 2 GB for applications.

Applications are limited by user mode. All applications run in the same user mode.

No, that sounds like nothing I have ever seen.

Please, source?

(You have a per-application limit as well)

@badp msdn.microsoft.com/en-us/library/aa366778%28v=vs.85%29.aspx

6:36 PM

It kinda makes sense to count swap in the addressable memory space

Also msdn.microsoft.com/en-us/library/bb613473(v=vs.85).aspx

but an OS that must take 2 GB, no matter how much space it needs is pure nonsense

> The virtual address space is divided so that 2 GB is available to the application and the other 2 GB is available only to the system.

Unless you use a special switch, in which case it's more like 3/1

@badp It doesn't use up 2 GB, it just allocates it.

Ah, it's a windows only thing.

Then fucking meh.

@badp Of course.

Linux does swap much better, anyway.

6:38 PM

Yeah, then you should mention that it doesn't apply to other OSes.

Well, I did. Fabian didn't.

> There are many misconceptions about the memory limit in 32-bit Windows OSes.

Yeah, you didn't write "Other OSes have other limitations", maybe at the bottom.

Because I don't know that. I only looked at Windows.

Feel free to not improve your answer though

I'd have to improve the question. It's about Windows.

6:39 PM

...and suffer consequences!

Fine, I'll add it in for people who can't read.

The rest of us appreciate that.

lunixbochs nicely illustrated the other RAM myth.

@ChrisF Would you mind it if I merged your answer onto the original question?

Yes, VRAM cuts into your addressing space. No, this does not change the fact you only get 2 GB.

6:44 PM

(Once the asker and/or the community does accept my closing)

@badp Feel free. Do you think it adds anything?

@ChrisF Yep, when it was asked when beds weren't yet in place

also I don't think the point of grass + torches = friendly mob, but not necessarily hostile mob has been made yet on the site.

We just got a question on Skeptics.SE "Can we say capitalism failed?" tagged as 2012 and mind-control. I think it's going to be closed ;-)
