Ok, how much memory (ram) does xp professional support? I ordered two sticks of 2 gb each for my computer, plus i have 1 stick for a total of 5 gb kingston ram. If i put all of them in, computer will not boot up, but if i put the two sticks of 2 gb for a total of 4gb ram, then go check the system, it says i have 3.25 gb ram...im confused. Anyone?? Rolling Eyes It is a new processor too, AMD 64x2 6000+.

I believe Lucky_Luke said 4 GB, and I'm sure he'd know.

I have two red and two black slots. Apparently I can only use either the
red slots or the black slots, but not both. So since my slots are full I can
not increase memory without replacing all of my memory.

See my knowledge base article for how to increase the working memory
and/or processor slice available for offline campaigns.

Hardware: Most modern mobos support up to 8 GB of RAM (4 x 2 GB cards)
OS: 32bit OS's support up to 3GB of RAM and 64bit OS's can support up to... a lot. Probably 64GB.

I have 4GB of RAM (4 x 1GB cards) and 64bit OS's in order to have all of it available (stripped-down WinXP Pro x64 for games and Ubuntu 7.10 AMD64 for anything else) BUT (and a BIG "but") the upper 2GB of RAM can't be accessed by 32bit apps, and IL2 is a 32bit app (as any other game) so from a game's point of view there's no difference between 2GB and 4GB of RAM because only 2GB are accessible to 32bit apps anyway.
For a 32bit app like IL2, anything over 2GB is unusable, and besides, drivers choice is much more limited using 64bit systems.
On the other hand, you may have a bunch of 64bit apps running in the part of RAM that's il2 can't access (as long as they aren't heavy n the processor)

One alternative to the "mega-RAM system" could be to get a superfast flash drive and put your paging file on it, so your virtual memory will be read much faster.

Another alternative could be a 64bit OS with 4GB of RAM, with a fixed size page file in a ramdisk that runs in the part of memory that 32bit apps can't access (they would access it as ramdisk because they would "think" that it's a HDD)

I strongly suspect that the pagefile-on-ramdisk idea must have some major flaws that I have missed even though it's right before my nose, because if it wasn't so, many people would be doing that already.
The pagefile-on-flashdrive sounds good in theory but I don't even know if flash drives of appropriate size are fast enough to offer a real gain over the usual pagefile on HDD (and I'm not even considering the possibility of techincal issues)

Anyways, the question was "how much RAM" and the answer is that 32bit systems can use max 3GB of RAM and 64bit systems support LOTS of RAM in comparison, I think it0s something like 64GB but I'm not really suree about that figure.

Direct from Uncle Billy's mouth....

Windows XP Professional and Windows Server 2003 Memory Support.
The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is also 4 GB.


For 64 bit OS....Up to 1 TB (terrabite) RAM

Maybe there a trick to make WinXP 32bit use all 4GB of RAM but I couldn't figure that out.
All I know is that when I switched to a 32bit system to see if the wider driver choice could help with my rendering problems, the system tab reported only 3GB of RAM installed. Same for Ubuntu: I installed a x86 version because some x64 apps have issue (most annoying Firefox refusing to run Java) and even the mighty Linux would only use 3GB of RAM (I eventually installed a 32bit Firefox on a 64bit Ubuntu)

1TB?!? now that's *some* RAM
I was unsure whether it was 64 or 640GB (I was almost certain it was something with a '64' in it... but maybe that was the 64 in 64bit) I eventually decided for "probably 64" because 640 sounded like too much. I mean, I remember like it was yesterday: "128MB of RAM?!? What on Earth do you need 128MB of RAM for?!?"

My first computer filled a room and ate punched cards! No monitor either, just paper printout.

By the way, the transistor was invented in 1948 (but I missed that!). Progress is amazing!

I worked on those TTY's too and likewise missed 1948.
Designed and build my first computer together with a friend in 78
It had a Z80B (blazingly fast at the time) 128 kB bank switched RAM and our pascal compiler and OS was able to service 4 workstations simultaneously. We later hooked up a fridge-sized hard drive we bought second hand from the university. 5 or 10 MB iirc. When the system started all the lights in the house dimmed. (the HD was a 3 phase 380 volt model we ran on 220V

The first computer I used ran MS-DOS and didn't have a hard drive but just two floppys. besides that one-week experience, I missed the whole 80's and most of the 90's stuff because I wasn't a socially challenged nerd (I became one as an adult)

-MY- first computer came much later, in early 96, or late 95, something like that.
It was a Win95 machine with 133MhZ CPU and 16MB of RAM that I later upgraded to 32MBand it also had a 1GB HDD that was considered huge "you will never use all that disk space anyway" <= ever heard that before? It must be the most commonly told lie in computer history.


Interesting
<= Thanks Max (yet another system reinstall is slowly appearing on the horizon...)

LOL yes i remember that old saying "you will never use all that disk space anyway". Now i have 1 80 gb, two 200 gb, and 1 external 200 gb. I will never use all that disk space. LOL.
On an lighter note, i installed windows vista and it crashed the next day, installed windows xp home edition, then decided to try vista again, so thats what im running now and it seems to be doing better with the updates and the list of "tweaks" mentioned in the other post. Vista has potential, and i will probably save my pennies and go with the Ultimate 64 bit version soon, im just glad i can make a backup copy of IL2 and it doesnt require going thru the setup process again. Thats great!!!
