System Reserved Memory

[critter1227]

I purchased some parts to build a pc and used some older ones, including 

• Gigabyte gtx 660
• Rosewill 630-Watt PSU
• Gigabyte GA-970A-DS3P ATX motherboard
• Amd FX 4100

While using older parts I had, like a 1tb green hdd, a 500gb green hdd and 6gb of 1333mhz ram, split into 3 2gb sticks.

According to both windows 7 ultimate 64bit and windows 8.1 pro 64bit. According to speccy, system property's there are 6gbs of ram, but only 3.6 are usable. I tried switching my sticks around and removing one. If I do so there is only 1.8 usable. I moved them around so it,s empty,2,2,2, giving the same effects. I check msconfig and tried settings it to max ram manually and unchecking the box. There are no updates for my bios, the max ram is 32gbs. Is there any solutions, is my board bad or is my ram bad?

Now I seem to say this to everyone who has this issue, are you sure you got 64bit OS?

I was able to install 64bit adobe programs, on windows 8, and I am certain windows 7 was 64bit, I am not physically near the computer today, but when I am able to, I can run a linux live cd to check. But I am 95% sure it is 64bit.

 

Edit: Forgot to mention it is samsung ram I stole from a hp pavilion desktop. It is all the same ram.

Go to

Control Panel -> System

to find out if you are using a 64 bit version of Windows.

Download Prime 95 from

and run it like Linus does in this video. This will check your RAM.

I suspect that one of your sticks of RAM is no longer working properly.
