Max RAM

[David Berry]

How much RAM does Windows Vista recognize?
I have a Dell XPS 410 with 4 GIG of RAM. Windows XP only showed 3 GIG of RAM but I just installed Vista Ultimate (32 bit) and it only shows 3 GIG as well. Why? I thought Vista recognized 4 GIG

It does support and will use 4Gb - but there are various hardware
issues that mean a lot of people only see 3 or 3.2 GB in the UI.
But 4Gb is supported and in use.

Hi!

With Vista 64-BITS, you will see your 4 GIG.

Bye!

Hardware Issues??

Sounds like a bug to me...

Up to 4GB on 32-bit. In 64-bit It's 8GB for Home Basic, 16GB for Home
Premium and 128GB for the higher SKUs.

In a 32-bit system the total address space is 4GB, by the time the hardware
has taken its share of the address space there isn't the total 4GB range
assigned to RAM.

Nope. It's normal. Since a 32-bit OS can only address
4 GB max, some of that space has to be used for video adapter
RAM, PCI card ROMS, various I/O functions. If you had a 64-bit
OS, that space could be above the 4 GB mark and so you'd see all
4 GB in use by Vista. According to the Knowledge base article,
the missing RAM is moved above the 4 GB mark and so isn't used
unless you use the /PAE switch which pages it in and out of the 4 GB
space.

What type of hardware issues?

 

[David Berry]

Is there a way to verify that there is 4 GIG and it's not a bad memory
stick?

You can boot with the Vista DVD and run the memory diagnostic.

Check in the BIOS to see if all the memory is detected.

This worked on my DFI NF-D
I am not an expert ( but I read many posts & then tried this )
& the issues was fixed 1st try... !! : ' )
enter Bios
Advance chipset features
memory hole for PCI MMIO
enable feature!
this feature is to remap to address above 4G of ram
save settings & exist
its all there now! from 3070 to 4094!
