16.0GB (14.9GB Useable) Issue

icybeach · Aug 8, 2014

I have recently built a PC and have been experiencing an issue when I look at the amount of memory I have, which was a cause for concern when I was looking around for a fix of the "Display driver crashed and recovered" error.

I have looked all over place and have also been told it is a common windows bug, but I don't really know what's happening.

I don't know what's causing the issue, and have tried several things such as:
Replacing the memory sticks
Updating the BIOS
Changing the page file to recommended
Removing most startup programs
Unticking the CPU and RAM boxes in MSConfig

my PC specs are:

AMD A10-7850K (2.7GHz)
ATI R9 270X
MSI A88X-G43
16GB RAM
750W PSU
Windows 7 Professional 64 Bit

I've looked around the BIOS and couldn't find anything even resembling memory mapping, so I'm completely out of ideas to try (apart from reinstalling windows, which I'll do if it's the only other way).
I figured since there isn't a single "clear" fix for this, it could be specific to my system specs.
Thanks in advance to anyone who can help out!

That's normal. Some of it will be allocated to running the integrated graphics.

i7Baby :

Can you elaborate on that at all?
what do you mean by running the integrated graphics?
for a few other people I know it just displays the RAM as "xxGB" without the brackets.
I find it hard to believe that over 1GB of my RAM would be allocated for BIOS and graphics.

An A10-7850K is not just a cpu. Its a cpu combined with a graphics card chip - an 'apu'. The graphics card portion needs to use some ram to run. In bios you can change how much ram is allocated to it. Usually its 2gb max. My guess is that in your case about 1 gb is allocated.

Also other ram gets allocated for other tasks. So you don't end up with all of it to use.

@i7Baby - will that happen even when he's got a dedicated GPU (the R9 270X)? Unless he's running Dual Graphics, in which case...

@OP - Can you check if you're running Dual Graphics (Hybrid Crossfire) in the AMD CC?

If it's a helpless issue, I guess I just gotta suck it in..

Also, I'm not sure how to check for that, can you help?
I've always had Intel and Nvidia, this is the first time using AMD and ATI

EDIT: I just checked device manager, and they both seem to be enabled.
dxdiag shows me that I'm only using one, so I don't think that I am using Dual Graphics..

DOUBLEEDIT: Managed to fix it by disabling the Integrated graphics through BIOS
thanks for helping me out guys <3

Depends on the motherboard whether the allocation to integrated graphics is turned off when you switch to discrete. But you can always change the allocation in bios. My cpu doesn't even have integrated graphics, but still 3 of my 16gb is used for 'cache' - memory used to help speed up processes.

Actually, although the system allocates some RAM to certain programs or the APU, it's not really used. The system makes a virtual cache (only a calculation) for them to be used when necesary. So the cached RAM is actually free RAM. And the system shows you that, because on full system load the APU draws that amount of RAM for usage. So long story short, your system can use all the RAM, but some of it goes to the APU. And keep in mind that the more RAM is installed, the more the system will use. And it's not a bad thing because it indexes some programs for quick acces, and you cannot call it "wasted RAM".
