Windows 7 6Gb Ram - 3.25Gb Usable

[Anh Tran]

Hey Guys basically i replaced my mobo and installed 6GB ram
However i only get 3.25 usable.

Before i changed my mobo since it was faulty i had 4GB ram which ran all 4GB ram.
Adding the 2GB total 6GB only allow me to use 3.25GB ram
Taking 2GB total 4GB ram allow me to use 2GB ram.

I don't know why!!

I currently have 6GB ram installed.

In bios it says 4024mb , Windows say i have 6GB (3.25GB usable)

Anyhelp?

Hi,

Thanks for everyones help!!!!!!
I appreicaite it so much for the replys.

I have finally fixed the problem

One of the new ram i had was damage somehow and bios could not read the ram which didn't show up.
Removing this solved the problem of the unusable memory

Now i have 4GB installed and 4GB usable

> got to contact scan for a replacement now.

How many memory slots, you may have to run 8 gigs instead of six, your board may require if you have 4 memory slots to have them all filled or just two of them filled as you have now. You may not be able to just use 3 slots. Is the memory the same type? mixing and matching memory does not work.

Cool, glad it's resolved! Certainly, as was mentioned a while back, did seem to point @ bad RAM somewhere.

Cheers,

Yeah it has 4 Ram Slot
2 slot already filled with 2GB * 2

I have extra 2gb * 2

But both are faulty as one is damage so bios can't find it the other jsut some mem probs when i ran memtest
Thanks again Everyone!

Hi Rakesh,

I'm not sure what your query is or what help it is you seek. If, it is the fact that you have 6GB RAM in your machine & yet, it is seeing 3.25 as useable... this is right & normal. It simply means you have a 32-bit machine & or OS. x86 stops @ 3.25, no matter how much RAM is actually in the machine. x64 will see & use more.

Cheers,
Drew
