Hey,
I've just brought a Compaq nx9110, it has a 128mb Radeon graphics card and 512mb RAM (Shared). Why share RAM when you have a graphics card with a reasonable amount of memory?

Anyway, from My Computer, Properties I only see 384MB RAM. System info indicates that there are 512MB. I checked with the vendor and they told me that it had 512MB, I think that a 256 module is built in and shared.

Anyway, he explained that I could adjust some settings to change that senario. I didn't really listen much more figuring I knew what to do...

No matter what I try windows is still saying 384MB RAM. Why? I can only find settings for performance and turning of flash display type things.

Any thoughts?

Even though it has an ATI graphics card it is stil using 128MB of the system RAM for the graphics card. 512MB - 128MB = 384MB left for the system.
The graphics card doesn't have it's own RAM in that model of laptop.
In the BIOS you may be able to tell the laptop to only share 64MB with the graphics card but you will never get the full 512MB back for windows unless you upgrade the RAM :D

Hmmm,
I guess a memory upgrade some time in the future will be needed.
Some specs sheets occur to me to be less than honest.

Nevermind.
It is still a nice machine.

It'll be interesting to see how it handles video (which is why I was keen on 512 with 128 memory in the card, which apparently does not exist).

Would I be better off leaving 128 with the graphics or moving to 64?
Cheers

Well, it's not "really" misleading. :D They assume you know that a laptop has a video chipset on the motherboard, not a physical video card with its own memory. It's a matter of space in the case.

Simplest way to find out if you should reduce the shared memory to 64MB is to try it. If it still does everything you want, that's the right setting, and you'll gain 64MB for MS to use. ;-)

Many of the laptops using the radeon chipset have their own dedicated ram that is independent of the system ram,not in this case though.

I wouldn't have called it misleading,although i would sugest some real research before making a purchase of a few thousand dollars,of course if that had been undertaken they would have a nicy shiny powerful asus laptop instead of a compaq

Unless you upgrade the graphics.

Goodness metla,
Don't you watch TV ? Compaq have much bigger ads than Asus, so they must be good.

How clear is the paper work , What did the sales person really say??

You Brought this as 512 + 168 g/card. It is not what you have, these people do this all the time and get away with it.

My advise, Take it back, do the seal thing in a shop full of customers, get a free ram upgrade to at least what you understood you were buying, or your money back

Read the original post.

It was bought with 512 MB of shared memory
Thats all that is required to be stated. It has 512 MB. "Shared" can only have the one meaning these days, its in common usage related to computer memory.

The advice to make a scene in the shop is a little unwise in reality.

Caveat Emptor, however its still got adequate RAM for most purposes.
I doubt any difference would be noticed by increasing it, however throttling the shared portion back to 32 or 64 MB would be quite viable.

My laptop uses shared RAM, normally I have it on 32 MB. It had 256 MB shared and I increased it to 512 (less the 32 shared) but noticed no difference at all in performance.

All very good points.

I am a retailer, "Caveat Emptor" definatley.

The number of "Sales Persons" taking "Unfair advantage" of things like the "shared memory issue" makes it harder for honest retailers to compete fairly.

The buyer in this did not understand what "Shared Memory" ment untill after he had payed.

If you feel youve' been "legally tucked" the "seal thing" can sometimes get results, including the end of any viable relationship with that retailer (Hence use with caution in smaller retailer communities).
