I think you have a 32 bit operating system, if so it will only recognize 4g.  You 64 bit to use higher numbers.

Please... Publish a Snapshot using Speccy taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
 
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
 
post-33068-0-86653600-1480692866_thumb.j

     Now, at the top, click File > Publish Snapshot.

     Click Yes > then Copy to Clipboard

Now, once you are back in the forum topic you are posting in, click the ADD REPLY or REPLY TO THIS TOPIC button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.

Again, please publish a Speccy full system snapshot as requested.  There is a lot of information included that helps assistants to diagnose what may be occurring.

When I added ram to my mini Acer this is what I had to do, went crazy for an answer at first this was so simple!

Change maximum memory option. Run msconfig, choose Boot tab, click on advanced options. ensure the Maximum memory checkbox were cleared

This was in 7 may or may not work in 10

@OldPhil, I tried that and didn't change.

 

Here is the Speccy Full System snapshot

Speccy shows 12GB...4GB x 2 and 2GB x 2.

 

12GB is reflected in the summary data and the specific hardware detail.

Question how do you know it is only using 4, I have 16 and rarely see 4-5 gigs being used in performance though I am sure it does at times.

Old Phil,

 

           See the original screen shot pair that was posted.  The standard Windows system information dialog shows 12.0 GB (4.00 GB usable).  That is really odd, I must admit.  I've seen instances where things like 8.0 GB (6.95 GB usable) show up, but never a discrepancy that's this large.

It may be that the crucial and the CORSIAR are not playing well together, if they are indeed CORSIAR.

 

I wonder what Brand those 2GB Chips are?

 

And there seems to be an issue with the HDD

Yeah windows does not like mixing and matching of RAM brands, i have had bluescreens because of it.

Linux does fine with mixed ram but windows is like "OMAIGAWDPANIC!"

I shall simply say that this does not conform with my personal experience with Windows.  I have upgraded the memory in almost all of my machines, and usually with mismatched RAM (and sometimes not just brand).  They've all hummed along.

 

It's really interesting to see how individual experiences can differ so much.  It also points out why anecdotal evidence (including mine, I hasten to add) is always something one must be careful about accepting without question.  Even if it's not scientifically controlled, the larger your number of data points the more likely it is that something approximating "the general circumstance" will emerge.

I've had an experience where a system appeared to work with Windows 7 (however it was blue screening randomly) but it absolutely refused to install Linux at all, with the Ubuntu installer consistently crashing.  That turned out to be an issue with mixed memory being installed.  Both worked fine once the incompatible memory was removed.

 

As for the issue at hand, I can't seem to get the link to the motherboard manual to work, which I believe is - http://www.foxconnchannel.com/driverdownload/Motherboard/AMD/Socket%20AM3/CinemaII/Manual/English/CinemaII-En-manual-v1.0.zip

 

If I could see the manual hopefully it would set out what memory slot was linked to which channel.

 

According to Speccy the memory is currently installed as:

 

Slot 1: 4 Gb

Slot 2: 4 Gb

Slot 3: 2 Gb

Slot 4: 2 Gb

 

I would perhaps consider moving them to some other positions e.g:

 

Slot 1: 2 Gb

Slot 2: 2 Gb

Slot 3: 4 Gb

Slot 4: 4 Gb

 

And see if that makes a difference to the amount of usable memory.  If not maybe try arranging them as 2 Gb, 4 Gb, 2 Gb, 4 Gb.

 

At worst, perhaps try running only the 4 Gb modules in dual channel mode and see if it picks up the full 8 Gb as usable.  It would at least be an improvement.
