WINXP 4gb RAM??

[abit]

I got 4x1gb and bumped in to Windows RAM ignorance problem.
Win giving me 3gb+ something crap.
BIOS meanwhile shows 4.005 of RAM.
This is with XPPro.
If anybody know this trick, please post.
Thanx in advance.

HI,
windows at best will see 3.8G usually 3.6
accessing usually only 2.5-2.8G

there are tweaks for this but are hit and miss.

search for the 3G memory switch

Thanx man.
I know it's a switch.
For boot.ini.

The ? was if anybody did it, how they did it, what line did they use and what the outcome.
Coz MS site is killing me..

not all mother boards can address 4gb of memory. The motherboards themself reserve some of the memory for hardware on the motherboard. If you disable some of the unused hardware on the mobo, it might give you some more RAM to use by the OS. Note I said might. I have a nf4 mobo that will not address a full 4gb of ram. I suggest that you check the manual for more info.

I have X5DAL-G SuperMicro.
In spec it is 8GB of RAM max.
I called SuperMicro and they sent me to Microsoft,
cuz BOIS(after I flashed it) does show 4gb, so it's not there fault.
And there is no really complain concerning SuperMicro.

I understand your point, U right and thank U.
Everything possible I can live without in my system is off.
It's optimized to minimum audio only requirements.

After some research I found out,
that it's well known issue in WindowsXP/XP Pro,
but could not find how to resolve.

It's suppose to be 3.75gb if some kinda key line inserted
in the boot.ini.
But what line I'm not sure I understood.
And MS site - make me sick.

That's why I thought if somebody here actually did it himself
and can give me info using plain human language.

[abit]

Hey Scott!
U're the guy who suppose to know this.
If not U then who.


Please, can U help a bit here.

I actually found several lines I can use,
and finally I got completely confused,
which one of them to use.
And I don't want really to mass up anything,
unless I know exactly what the deal is,
cuz my system right now very stable and works really well.
Thanx in advance.

windows xp can not address more than 4gb of ram.

you need a different operating system to see more memory.

More accurately, no machine with 32-bit addressing can access more than 4GB ram. You need a computer with 64-bit addressing.

there is a tweak for windows XP, to tell the Operatingsystem not adressing 2 giga for itself so only one gig.. because normally space is divided into 2 gig for OS, rest for applications.. or it will start sharing with externalizing memory on harddisk..

I will search for the tweak.. great performance improvements with virtual instruments witch need a lot of ram for loading the libraries..

[thenoodle]

I explored the XP 3gb switch last summer. I downloaded all the tweaking apps, collected all my notes..and just before I started a system mod, I discovered that half my music apps wouldn't address more than 1.5 or 2 gb anyway...it's coded into the apps. I wasn't going to gain anything by jumping to 4gb. So I simply left all the machines here at 2.5gb where they were.

I'm leaving the ram issue alone for now. It's sorta like blowing time to get Win98 to address more than 512mb ram.....not worth the time anymore. Within 12 months, Vista will be here, integrated with a few newer generations of 64 bit mobos/processors...and cheaper ram...addressable to 8-20gb (or whatever the initial standard is supposed to be). Vista is about to go into beta2, so the target release looks pretty accurate to me. I can live with a bunch of 2.5 gb ram machines for another year.

Exactly instruments/libs - this is what it all about.
Friend of mine works on G5 dual 2.0.
My sys at the moment Dual 2.8 Xeon -which is not the top of tops,
but very stable and have plenty of power, and his G5 can't bit me with performance at all.
The only difference really is how Xeon reacts to heavy VSTs.
And this is THE RAM department.
His has 4gb and it feels like there is no really limits.
He can open, and open, and open up stuff in there.., and there is no end to this.

That's why.
George, thanx in participating in this research man.
It would be a big help.

I just noticed that mobos goes with 4/8/16 RAM slots,
and 1gb sticks and 2gb sticks are out,
but can't see if anybody really use this power.
Unless U on sever NT/2003 or somethig..

2.5 is not actually bad, U have space to work no doubt.
So U didn't try the key.. Hmm.
In terms of 64bit and VISTA( sorry never head about, Longhorn yes) I can say,
in general I don't like to much to be the first guy in the block to try new stuff, sorry.
I mean, all of us did it in the past and learn this things the hard way
for so many times, so I prefer stability instead.
And it's reflecting our creative flaw a lot,
by spending so much time on tweaking instead of music..

Well, I think I'm gonna wait till all drivers and apps will be adapted
to new environment. Thanx for your input though. Make sense.

Longhorn was renamed to Vista

You can get windows xp pro x64 edition. It supports up to 128gb of ram. Just make sure your hardware has 64-bit drivers...

http://www.microsoft.com/windowsxp/6.../overview.mspx

[George Necola]

or you can start clustering, like the protools mac-farms do.. just get 3 PC's and then rock the castle..

well, we have 2 "ok-computers" at our laboratory, each workin at 16 gigabyte ram with dual opteron (because better floatingpoint, so better 3D processing) and it's cool.. I think I mentioned this already.. windows XP 64bit is running properly..

watch out that on 64bit system (I mean with WINDOWS 64bit) everything in 32bit will run slower!! (I experienced this with my 3D-programm) because all the dll's are running in emulated 32bit mode..

about the tweak: tweak XP can do the job on it's own.. there are some changes in the autoexec.bat (yes it's existing... but hidden) and the heart of your ^puter.. the registry..

will search and try hard

[George Necola]

found it!

http://support.microsoft.com/?scid=k...833721&x=8&y=9

look for /3GB

or direct:
http://support.microsoft.com/?scid=k...21120121120120

there was a detailed description somewhere how to do it.. maybe it will cross my way.

cheers and good luck!

if that system is "ok" whats that make mine?

[George Necola]

haha.. for voxelrendering.. 3D-pixel is a voxel.. yes.. that's a lot of work for a CPU one dataset is up to 8 gig.. thats a heavy load..

back to topic

Thanx George and to all slutz, I'll try next week /3gb and give U full report .

I used to run dual AMD 2800 sys about 2years back, I think ASUS based and
it was very powerful rig.
But finally I decided to let it go and luckily sold it,
cuz in terms of hardware compatibility, IRQ, blue screens, slut changes
it was sort of hell.
PXeon is much more friendly in this regards.

George , 32dlls slowing down .. ha..
here we go, that's why I don't want to be the first tweakhead here.
I mean, I am usually one, but I need to change this terrible habit.

Did U try to run any audio apps on 64 bit OS?
How the cards reaction, drivers plugz behavior all that?

Or if anybody did 64bit transfer, any experience would be highly appreciated.

AFAIK....... XP knows there is 4 gig of ram and is using it, however it cannot tell you it is, apparently it can only display up to 3 gig ram as being available.

I suspect mcrosoft, being about as forward looking as a goldfish with alzheimers, when they coded XP some wag said. Well it can address up to 4 gig or ram ..... the reply came yeahhhhhhhh right and who is ever going to able to afford 4 gig of ram?? its way easier to just encode it to show 3 gig but leave the option to use 4 gig just incase..

By the time 4 gig is affordable we'll be in Win3000 anway so dont sweat it.

Yeah, it sucks, but I can relate to the statement -
at the time XP was out 1gb was unbelievably huge amount of RAM.
Hey, I use to buy 16mb(!) for $200 - for Quadra 950..
Now for my mobo I got 1GB of pc2100 for like 80 bucks, which I think
is make sense if U really feel like it will improve your performance.

[George Necola]

4 giga are now about 350 bucks.. well.. I cant afford because I bought a new interface, card and valve pre and poweramp this month.. but 350$.. I mean.. common..

Congratulations on nu stuff!
Sure, it's not always that simple..

we have 2 "ok-computers" at our laboratory, each working at 16 gigabyte ram

Here we go.
If we doing it or trying to do it professionally, we just have to squeeze it
from the pocked, at some point at least.
Are we a gearslutz or what?!
