4 Gig memory. Vista doesn't think so

[Johnny|lucidcomposure]

So I have installed 4 gig of memory and vista says there is only
3,325,69

The post screen counted 4gig though.

??

 

[R@tman]

if you are running 32 bit vista thats all your going to get


64 bit will show the whole lot

 

[mmj_uk]

If you are running 32bit Vista it is normal, to utilise the full amount you will need 64bit Vista.

I thought it was over 4 gig that was the deal?

Either way as long as its normal I'm happy with that.

No it's over 3GB as you've now realised...

 

[Johnny|lucidcomposure]

Cheers thanks for clearing that up. Thought I had a dodgy stick then for a second.

no it's 4GB, but it's 4GB for Video and System Memory Combined.

So in other words, there's 675MB of RAM in your PC not being utilised.

no it means he has 675mb of Video ram, although he probly has 512mb gpu.

In my experience, the most RAM I've ever seen integrated graphics consume is 64/128mb.

 

[yantorsen]

who said he's using intergrated graphics?

Why did I click on your sig? ^ LOL

Not only for those, also for the pci, pcie busses etc...

I had 3.2 ghz too in xp when I tryed 4gb.
On the other hand, that was shown in post screen already so I don't know, didn't try 4gb yet on my p5b deluxe as my slower RAM wouldn't be able to keep up with my OC.

3.2ghz ram isnt what I'd call slow

That has nothing to do with it though. Basically there are a lot of devices in the average PC nowadays that will need to map their onboard memory into the virtual memory address space. Graphics cards are just one of these. Even network cards and SATA controllers do it.

That's why on 32-bit operating systems there is usually a large chunk of "missing" main memory. It's because that memory can't be mapped to any location on a virtual memory address space.

So you're saying you can't use the unmapped memory, unless you using a 64-bit CPU and OS?

 

[Rebelius]

if you have a 64-bit OS then you still can't use "unmapped memory" however, the system can map a LOT more RAM (16exabytes or something similarly insane)


Is it no coincidence that it's RAM that doesn't get address space when you have too much? It never happens to be some other component that just won't work?

my 6150 on my board can take upto 512meg in windows, bios its only 128meg, the driver is boosting it.

Correct but then x64 is the way forward and this is just one implicit improvement of thousands.
