4gb ram in Vista - Page 3

post #21 of 51
A 32 bit OS can use up to 4GB of memory. That includes VRAM and system RAM.
So if your video card is 512mb, and you have 4gb of system RAM, it will see and only use 3.5GB of system RAM.
If you had no dedicated video RAM, Vista will see and use all 4gb of system RAM.

Also, microsoft recently developed a patch, can't remember if it is out yet or not, that lets an amount of memory above 4GB show up in a 32bit environment. This does not allow the system to use the memory, but allows the user to see the correct amount of memory installed.

Yeah but it only shows 4GB+. It still can't use it
But that's still better than it showing much less than what you actually have installed

Doesn't the memory use also include page file?

I had 4 gigs installed just messing around and only showed just over 3 gigs, and I have a 256mb video card.

Log into windows with the 2 sticks of RAM and then download the patch for 4GB of ram for windows vista 32 bit edition.

Both versions: KB29777

That fix is not described as anything that addresses what we are talking about.

"Most users will be sobered when they equip their systems with 4 GB of RAM and find that only 3 GB is recognized by the BIOS and by Windows. This is neither a bug nor due to any hardware error. The explanation is simple: 32-bit systems can only address up to 4 GB of memory. Additionally, many add-in cards and on-board controllers require memory addresses in order to be accessible. This is called "Memory Mapped IO" (MMIO). Since this memory range has to lie within the 4 GB, it is subtracted from the installed and available RAM."

I just changed my pagefile to 1/3 of it's original size and it did not change the amount of Ram that Vista can see.

Once again..... let's have one of you who say this works, post a picture of the Vista OS ram size from the system information screen under the control panel in vista.

I have 4GB installed now and my video card has 320MB and Vista shows 2814MB like i posted above in this thread. But cpuz shows all 4096MB on the memory tab.

Someone prove this instead of us chasing our tails speculating.
