4GB: The Next RAM Barrier

David Strom writes:

''Back in the early days of DOS, we had a memory barrier of 640kB of memory.

I know, it seems quaint now, something that you can find on the chipsets of audio greeting cards rather than real computers, but we spent a lot of time juggling applications to fit in that space. We had special hardware cards that could address more memory, and we had swapping programs (remember Quarterdeck?) that could allow us to run bigger apps. (And for those of us who are really old, we even remember the 64kB barrier of the earliest Apple // computers!)''

You can adress far more than 4GB with the right OS, i.e. XP/Vista 64Bit and the hardware, 64-Bit CPUs, as you said.

BTW, how come you are in the open zone?

Its RAm ram ram ie Horse power.....

Heres a thinker.. think smart like APPLE and RUn a Finished OS that MS tryed to Copy and Mabey u wont need x-ram everytime.

My Old MAc running 512ram is Doing Fine. and i RUN CRAP LOADS OF THINGS!!!!!!

lol whatever u droids have to convince yourself to imagine Cell makes PS3's crap ram alllll better now.

ram = everything.

Uh Pain: ...Stop being a raging Mac fanboy for a second and think about what OTHER people do with they're computers.

People who do 3d graphic design, or people who play the latest computer games.. They need large amounts of RAM for the GAME or GRAPHICS PROGRAMS..

3D Models can become GB's in size depending on detail and complexity. #D Modelers need a lot of RAM.

And games are advancing really fast and are needing more and more RAM.

Yeah a person like you who might play a few not so high end games and just surf the net on your computer, this RAM issue doesn't matter to you. MAC or Windows.

This pertains to other people.

4 Gigs is the barrier for 32 bit computing, it's too bad more has not been done software side to expedite the embracing of the 64 bit architectures that have been around for the last 4 years.

deeznuts6589d ago

4 gigs is the theoretical limit but I think it's even less, due to graphics etc.

You really only get a bit more than 3 if you install 4. Intuitive isn't it?

Kakkoii6589d ago (Edited 6589d ago )

deeznuts: Actually...

That's a fault with 32bit Windows.

There is a patch you can get that allows Windows XP to detect all 4GB of the RAM.

PAE - Physical Address Extension

Windows Server 2003 SP1, Datacenter Edition can use up to 128 GB of physical RAM with PAE enabled.

Windows XP can use up to 4GB.

titntin6589d ago

Yeah the 4 gig limit is a real pain to me on this machine, and I really need to more ram - I doa lot of intensive 3D.

The worst thing is that with XP professional you opnly get 3 gig of the 4 gig you have installed! That just adds insult to injury! :)

titntin6589d ago

Doesn't run any of thre apps I HAVE to run. Some of my customers run older versions of Max or Maya (to fit their pipeline) and I have to be able to run these legacy versions.

Anyway, there seeems no point in having a bit more memory only to let a resource hogging OS gobble it all up! :) Don't I need 4 gig just for Vista? lol

y0haN6589d ago

It's not Windows XP's fault, it's a 32-bit (or x86) architecture which physically can't address more than 4 GB of memory. This includes graphics memory and others so that is why you're only able to see 3 GB of RAM addressed. Get a 64-bit OS if your applications support them.

Not looking good. Hopefully Asha Sharma is able to turn Phil’s disaster around.

To me it's still quite remarkable how they can cash-in 5.3bn in revenue in a single quarter, since their hardware is basically dead.

Jingsing30d ago

The stock mark is what makes Microsoft remarkable, They have convinced every institutional and retail investor to just keep piling money into them. Like many big tech giants they are just a big growing pyramid scheme. As long as people keep dropping money into ETF's that cover the market Microsoft will always be liquid. At the same time it is completely stifling innovation and competition. People need to start being more discreet in how they invest their money as it's killing the system.

Tanktopmaster9230d ago

Once they re-evaluate exclusive all will be fine….

S2Killinit30d ago

Riiiiight because people will just flock back to them for one or two games per year.

Jingsing30d ago

15+ years of bad performance is what they call irreparable in business. It is time for them to sell off the assets and get out of entertainment.

Tanktopmaster9230d ago

These declines are on the back of extra revenue received from releasing games like Forza horizon 5 on PlayStation. So I’m being sarcastic here when I said they should go back to exclusives. Killing off a revenue stream from Ps5 sales will only make things worse
