Memory Clarification, must read.

post #1 of 15
Thread Starter 
So, after all who has been saying "ZOMG 32-bit only sees up to ~3.5 GB of your RAM", I'm going to rant a bit.

Do your research! By enabling PAE (Physical Address Emulation), all your RAM is getting remapped to above the 4GB limit--allowing for up to 16GB (The magic word: up to) visible on your 32-bit install, and they're usable too!

So anyone who's been saying that 32-bit only can see (magic word is "only") 4GB minus your graphics cards memory, get your facts right.

Rant over, and I want everyone to read this.

That should also be noted as a con for 32-bit. I've yet to see a single every-day app/game attempt to use much more than 2-3GB of RAM, though.

and HOW does one enable it? (is it a bios option, or something in control panel?)

yah, a bit lazy to find out myself.

Yes gonX...you need findings to support your statement
Nevermind I found it...but you still didn't explain why you were ranting about it?

How does that effect running in emulation mode for that stuff. Is there a impact on performance.

Well, it is correct to say that a 32-bit OS cannot utilize more than 4GB of memory... If you have to emulate the memory address, then you are modifying the OS.

So it is correct to say that a 32 bit OS cannot access more than 4GB of memory. It is also correct to say that the 32 bit OS can be modified to access it.

It's found in the BIOS, usually near your DRAM timings, or advanced chipset options... I am ranting about it because people keep saying "lolz 32-bit will onleh c 3.5gb of RAM so get 64-bit"

It simply just remaps everything above the 4GB limit, enabling up to 16 (which actually only should be 12) GB's of RAM to be seen, and because of that, Windows doesn't see anything in the first 4GB's, (from this point, it's pure speculation) so it deactivates the 4GB limit, enabling all 16 (now 12 because the first 4 are unmapped) GB's to be shown.

Hope this explains it well enough

Interesting enough. I am still gonna stick with 64 bit though.

Chears for a good point though.

You can obviously always install 64-bit if you want to, but suggesting a person to buy 64-bit (when he already has 32-bit) due to the memory issue should just stop posting already.

Who ever said Physical Addresses in x86 processors were 32bit?

Micro Processors, since the Pentium 3 era have supported 32 bit Virtual Addresses.
However, they do not contain 32 bit Physical addresses. Instead they contain 36 bit Physical addresses, therefore limiting the system to a maximum of 64GB of Physical Memory.

Physical Addresses have never been the problem therefore since the Pentium 3 era, since desktop systems do not require 64GB System Memory to function, even in high end computation.

However, the issue lies with the Virtual Address size of 32 bit, this therefore limits the system to addressing 4GB of Physical Memory (Per application).

A Physical Address larger than the Virtual Address (like we see in this case) means that the computer system could have more Memory than one program could actually access. However, this is useful for running multiple programs simultaneously if you could emulate additional Virtual Addresses to permit the additional Addressing of System Memory.

The system sees Windows as an Individual Program, and therefore allocates the system 4GB of System Memory (as per Virtual Addressing Standards). However, if you could fool the system into thinking Windows was not a singular program, and a multiple program system you could increase the Memory Capacity that can be allocated to it.

Please Note: No application within Windows, even with this "cheat" enabled will be capable of addressing more than 4096MB of System Memory within the Operating system without a Second Layer of Emulation or splitting the executable files into multiple files (or equivalent). Two applications could address 4096MB each however.
