[HELP] Shared system memory?

[Skeng]

I have 9GB of RAM three sticks of 2GB and three sticks of 1GB but 3GB (three sticks of 1GB) is missing. It also says that 2GB of that is going to shared system memory. CPUZ manages to see that I have 9GB but windows is only showing 6GB. What's going on here :S

Do the 3 xGb modules work on their own?

As for the sharing, I beleive your card, along with other devices is being mapped to main memeory - Memory Mapped Access or I/O (MMIO). I may stand corrected though.

The allocation of mapped memory depends on the device being installed. If you have a 1gb video card for example, then 1gb of system RAM will be made unavailable and reserved for that device. Thuis applies to other mapped devices such as sound cards, NICs etc. However, most graphics cards don’t need to reserve the entire memory pool, they simply reserve an overlay so the CPU and Windows can copy data to the GPU.

You can see what's being mapping:

run devmgmt.exe

Click View > an click on memory type.

I wouldn't worry about this too much tbh.

devmgmt.exe I cant find this command even using run.

devmgmt.msc is the fancy way of getting into device manager.

ok done but I cant find the memory type button :/

Never heard of it myself either. Do you really need 9GB? If not, just remove the 1GB modules. Are they all the same frequency and type? Mixing modules isn't recommended.

Sorry I wasn't quite that accurate.. Click on View>Resources by type

Have you tried just using the 1gb modules on their own, just to see they are ok as previously advised?
