Windows 7: 4GB Installed only 2GB usable

4GB Installed only 2GB usable

Sorry guys, I had to post another topic about this.

I already understand why PAE isn't enabled on 32-bit versions. This is making me uncomfortable seeing that only a half of the memory is being used and the remaining is sitting there doing nothing. I'm not even getting better performance it's basically just the same with my older setup.

Before I had 2GB of ram installed (in a 1 X 1 format, in dual channel) and System Information reports 2GB with no usable for additional information.

Now that I've swapped in a new motherboard (which is a DDR3 one), System Information reports that I only have 2GB usable out of 4GB (Single Stick 4GB)

I've checked hardware reserved, here's what it said:



According to my research, it should be using around 3.50 to 3.80GB for the RAM and the rest for the hardware. I've already tried using my 1GB graphics card on another identical system and is reporting 3.60GB of ram usable.

Is there a way of pushing it to atleast 3GB?

Hello Roaster maybe I am being a little over simplistic but have you tried the stick in the other slot?? and then looked in the Task Manager. I am asking because I am thinking maybe the stick is not good which in that case you might run a memtest on it.

Your motherboard specs.

Quote:
MEMORY Support Dual Channel DDR3 800/1066/1333(OC) MHz
2 x DDR3 DIMM Memory Slot
Max. Supports up to 8GB Memory
Note: FSB800 CPU only support DDR3-800
Your motherboard is dual channel. Which means with one stick of ram you are only in single channel.
It appears that each memory slot will only handle up to 4gb of ram.
You should have 2/4 gb ram modules.

Yep thats right Jack and why I wondered what if anything happened if the stick was put into the number two slot. Now it did also occur to me that some boards have a definite order of which slot to use first though I couldn't find anything on that board which is getting on in life.

Just checked the second RAM slot, it's not working. I put in a 1GB stick, it boots but only detects the 4GB one. I put in the 4GB stick on the other slot (that I am using), computer will have power but will not boot. No sticks installed then it will beep like it's tapping too fast. I couldn't install my second 4GB ram because it's incompatible.

I will try to run memtest when I have time as I am currently in the university.

Hi,
Having 2gb's as hardware reserved is ultimately your problem,
I'd look through your bios settings and see if you see any reasons for it.

Just checked the bios. My 4GB ram is fully detected. It says "4096 MB"

Hello

I went to the BIOS and this is what I could find. I have classes in the afternoon and I am currently on my way back when I posted this.

Hi,
Possibly you should enable memory remapping Oops better memory hole or try optimize defaults ?
Something is off onboard graphic's should be disabled when a real gpu is installed
I have a grand total of 1mb hardware reserved even though the bios shows otherwise :)

It either that or you have changed something in msconfig boot advanced options
