Thanxx alot for helping me MY nightmare are over i thought someting was wrong within my Hardware...(i may change my opreating system may be I will buy Vista this time).......anyway thanx again SERUNSON

Vista has the same bug I think

Hi Tksdevil

I don't know if you still access this thread or not. I recently purchased S975XBX2 and had a difficult time to get it booting with correct DDR2 SDRAM. Can you provide the part number of the Kingston memory that you are using for S975XBX2 mobo?

Regards

hi all , ive read this thread and the link you attached and I am understanding this i think If windows XP cannot address 4 or more gigs then let me ask a few questions which I hope someone can answer. I have 4 gigs of ram for GTA4 on PC, windows XP SP3 with dual core, .
I have 2 2 gig sticks of ram so I cannot make it 3 , and my properties also show 3.25.

1)is there a way to get it to use all 4 gigs on windows xp? (i remember you saying you can upgrade the bios.
2) does windows vista or a newer windows OS support 4 gigs, all i want is it to use 4 gigs.
thanks in advance for your help.
stevelindner@hotmail.com is my email ,

1) XP-64 does. You need a 64 bit operating system to use the full 4GB, but personally I wouldn't go XP-64. Vista was designed with 64 in mind, XP wasn't.
2) Vista-64 does. There is a 32 bit and 64 bit version of Vista too.

I mean technically a 32bit o/s can handle 4GB, but that's in total. Some is taken up by all the bits and pieces in your computer leaving about 3GB of address space for your RAM.

But for GTA4, the limitation for most people will be the RAM on their video card. I'm guessing you have 256 or 512 MB on your graphics card, which would mean that this is the limiting factor for how high you can turn up the graphics.

The New Normal has put it spot on and I'll just put that another way and add a suggestion.

1/
You are at least the 0.25GB better off by having added 1GB RAM.

2/
Assuming the 8600 to have 512MB RAM, this is added to the 3.25MB (actually it's subtracted off the top of the 4GB).

3/
Other devices claim another 256MB off the 4GB addressable space.

4/
Voila - you have used the 4GB memory allocation allowed in 32 bit OS. And, you now have 0.75GB of unused motherboard RAM.

5/
You can set up a RAM Disk to use that memory by means of some reasonably priced software and that's what I'm gonna do next week when my Qosmio arrives.

ok so here are my specs - dx diag summarized:

im wondering , seeing as how I am running xp pro , a 32 bit os - if I upgraded to vista 64 bit, will I be able to use the full potential of my new fatality ram. its 2 sticks , each are 2 gigs. im trying to smoth out gta 4s porting issues with faster and better ram than I had before.
if vista 64 will allow me to play better , I will just go out and buy it -
I do realize that all of my computers devices memory also accounts for a portion the 32 bit OS 4 GB ram addressing cap., video card included,
So im wondering if i get vista 64 , will I not have a memory addressing cap/maximum. And will it be default in the OS,or will I have to download a program or enable something to support the more than 4 GB addresses.
thanks again for helping me understand this.

I have Vista64 with all the latest patches and I can use my full 4GB of RAM. If you decide to go that route, I'd suggest installing with only 2GB, getting all the Vista updates, then putting in the other 2GB.

But is it really worth it for that 700MB? Vista uses more RAM than XP just to function, so your games won't get an extra 700. I doubt GTA4 is maxing out your system RAM at the moment anyway, although it would be fairly close (that game eats memory for breakfast).

The New Normal makes a lot of sense.

Bearing in mind that one of my systems is 64 bit, I had the opportunity of going 64 bit OS in the Qosmio. Unless I put 8GB in, I can't see the advantage when for a few $$ I can buy a RAM Disk program that works above the 4GB address range to use up the spare 3/4GB. I've got plenty to load in there to give me considerable time saving onn saving documents. But then I doubt you do what I do on my PCs.

I had same problem with 98 and 1 Giga Ram as it were not able to use because of address space for Graphic card.
If I am not wrong, XP could handle up to 4 Giga address space, and perhaps Your Graphic card is 512 or even 750 MBy, so You have spent money for no results.
But nowadays memory is cheap, I have RAMBUS type RAM some 7 years ago, and 1 Giga costed 2000$+ so I was really unhappy when 98 limited use of RAM to 768 Mby without as much as >>By Your leave....<<, telling me use of memory is restricted.
Now, I would like to buy MB that could have 128 Giga RAM, but if I would not be able to use it, then I shall wait OS that could handle this. Good old ATARI has had no such problems as PC, as it has had MOTOROLA 68040 with linear addressing, and OS and device drivers were loaded from start of RAM, and then I could have used as much RAM that was installed, up to 64 Mby, where PCs were limited to 4 Mby........
