Wonder if anyone can help?
A friend recently gave me a tower with a GA-945GCM-S2L MB, intel D processor 925, ATI radeon HD 3800.
When I recieved it there was no RAM so I bought 2 new 667 mhz 2GB ddr2 sticks and installed them.
I then went on to install a fresh copy of windows7 x64.
When I go into computer properties it says that it has 4GB (2GB usable), I have tried testing both slots with 1 stick of ram in each and it tells me the same thing only this time instead of 4GB it says 2GB (1GB usable).
It also recognises 4096 MB in CPU-Z?
Any help would be greatly appreciated.
Thanks.
 
Hi Hark, welcome to Computer Forum! :)

  1. Firstly double check that you have actually installed the 64bit version ;)
  2. Download the latest motherboard BIOS from gigabyte. Here is the download for BIOS VF8d
  3. Update the BIOS.
  4. Shutdown and open computer.
  5. Ensure you have the RAM in the correct dual channel slots (colour coded). While you're inside the case...
  6. Then clear the CMOS by unplugging the computer, removing the CMOS battery for 3 minutes and holding down the power button for 10 secs prior to reconnecting the battery and power cable.
  7. Start the computer and enter the BIOS.
  8. Re-set your BIOS settings.
  9. While in the BIOS, search for memory remapping and enable it.

Restart and see if that helps.

Thanks for the reply bigfellla,
Tried following the instructions you gave but still booted up saying that only 2 of 4gb were in use. I even installed a fresh copy of windows 7 x64. Also in the BIOS there wasn't the choice of memory mapping? the only thing that was close to that was system memory multiplier, I tried ajusting that and it made no difference.
Have you got any other ideas that I could try? :confused:

Thanks again for your help.
 
There is nothing wrong.
I assume you found this info in the resource monitor.
Memory is being shared between the RAM and the hdd.
 
Does this happen when using a dual processor? Because I had 4gb on my older computer which had a pentium 4 running win7 x32?
 
If you have 4gb installed in your system and as long as it says 4gb under system properties and cpu-z then you are fine. If system properties only show 2gb when you have 4gb installed then you have an issue.
 
So does the (2gb usable) next to the 4gb installed in computer properties not matter? Will games that require 3gb still work?
Thanks.
Hark.
