Ram upgrade

  Shutt1e 18:16 24 Jun 2009

Basically , i have 2gb of ram at the moment in my laptop. 1gb is being taken by my video card which is a Nvidia 8400m. So that leaves only 1gb left for applications. So will a upgrade of 1gb ram make alot of difference ? i frequently play world of warcraft and have web browsers open etc, so will it make a difference.

Isn't the 1gb RAM for the video card integral to the card and separate from the main system RAM.
In which case (if it is) the difference in 2 vs 3gb RAM will I suspect will be marginal.

The card has 128mb dedicated and takes about 900mb from the ram, because it comes up as 1041 mb.

Just add (assuming it's Vista) that you can put the CPU/RAM gadget on the sidebar and see at a glance how much RAM is in use. If it's getting toward the 70/80% mark when running tasks then yes, you may need more.

Posted together.
Try opening "performance and reliability" monitor and see what that shows. How much free is reported ?
Where are you seeing this 1041mb

i ran a test on systemrequirements labs, it said that my graphics card was 1041 mb, but it is a 128mb 8400m , so it is obviosuly taking ram. My ram is running at 89% , so i guess i should upgrade

It is quite common for video cards in laptops to share ram with the main ram sticks. in fact it doesn't share at all it just uses a chunk of system ram for its needs to improve graphics performance on the cheap. Turbocache (Nvidia) and HyperMemory (ATI) are 2 such systems. The whole thing is controlled from CMOS, sometimes u can adjust the amount shared, or not! also shared RAM is not reported to windows so if there is a missing chunk of sysytem RAM it will be the shared RAM. adding more System RAM will speed thing s up as it will in most systems. 1Gb sounds a lot to share so maybe u should look in the CMOS settings to see if u can adjust it down.

Don't know quite where you are up to with this but if I click right click a blank spot on the desktop and choose "personalise" and "Display setting" and "advanced" my graphics card (NVidia 6100) shows
Total available graphics 830mb
Dedicated 128mb
System memory 0
Shared 702mb

So I don't quite understand what that means !
I also have 2GB of RAM of which 63% is currently "free", so 702mb can't currently be in use as the whole PC is only showing as using 37% or so currently.
