So, I've had this issue in the past, and I figured that installing a brand new MOBO and brand new set of RAM sticks would fix it, but no such luck. I've tried just about every solution listed, including going into my new motherboards BIOS and manually setting my DRAM clock speed to 1600, and on my previous board I had tried resetting my mobo battery. I seem to be at a total loss here, can anyone help me out?

Is your mobo BIOS up to date?

 

[Rogue Leader]

The most common cause of this issue with an AMD processor is bent pins on the CPU. Its something that even if you replaced your motherboard would still happen because you would be using the same processor.

Carefully remove the processor and check the pins very closely. If there is a bent one very very carefully and gently push it back into place so it is perfect. In the worst case one of your pins will be broken, but lets keep our fingers crossed that is not it.

Yep, currently on the latest version.

Did that last night while installing my new board. Everything with the CPU is fine.

Excellent glad thats not bad.

So lets confirm, onboard GPU (if any) is disabled

Memory Remap (if feature is available) is enabled

In Windows, msconfig. Then boot, then advanced, and make sure no memory limit is set.

All good there?

Go into the bios and see if it reports all 16gb of ram is being detected.
If the ram is showing as the full 16Gb or 16,384MB.


Then your problem is windows os is capping use of the 16Gb you have fitted.

Let windows load up.

In the search box type: msconfig.
Click on the search result.

A new window will open up.
Click on the boot tab at the top of the new window.
Then click on the advanced options tab.

Look at the top of the new page shown.

Maximum memory:
If it has a value set of 8Gb or 8192 showing.

Click inside the box and delete or back space the value back to zero.
Untick the maximum memory check box above it.

Click on apply, ok.
Restart the system, and let windows load.

Open up system information.
And look at physical ram installed it should equal close to 16gb of ram.
The second box shows how much windows os has used of the memory.
And the last box shows what is left or free to run other programs.

The value put in the maximum memory box constrains the amount of physical system memory windows can see for use.
Even if the physical amount of memory fitted for example is 16 Gb via ram modules to the system or motherboard.

 

[mynameslars]

No data limit is set in MSConfig.

I'll head into BIOS and double check everything and take some screens. I'll post them in a few minutes when I reboot.

Sounds good. If you are 100% on the processor not having bent or missing pins there has to be some way this will be fixed in BIOS or software.

 

[COLGeek]

Never mind earlier comment. I saw "single channel" reference and became dazed and confused.

RL is right for asking, what does your BIOS see?

 

[Shaun o]

If you still cannot see a total in the bios of 16Gb.
You may want to check what the maximum amount of memory the board will support.

What size in density each memory slot will support. in Gb per stick.

That you have placed if two memory modules of 8Gb each in the right memory slot positions of your motherboard.
With some motherboards depending on the amount of sticks used it will state what memory slot each memory stick must be placed into for example Dual channel memory mode to be activated.

And the board can read the memory modules in a set order of the numbered memory slots.
And why it is important to make sure they are set in the right order of the four slots provided on the motherboard.

The only other limitation would be the version of the OS you are using.
if 32bit or a home or office, pro version of the os.

Here's some pictures straight from my BIOS. I also just tried lowering the DRAM clock even further to 1333, but it didn't help.

When you only 2 modules installed, does the system only register 8GB? I can't see your linked images from my current network location. How much memory does your BIOS "see" with all 4 modules installed?

 

[Calvin7]

Part Number CMX8GX3M2A1600C9 is an 8GB kit. Corsair doesn't guarantee compatibility when using multiple kits since they have never been tested together. Combining multiple kits can cause the PC not to boot and to not be able to operate at rated specifications.

You should use a single kit which is guaranteed to be compatible.

 

[mynameslars]

When you only 2 modules installed, does the system only register 8GB? I can't see your linked images from my current network location. How much memory does your BIOS "see" with all 4 modules installed?

It sees the total of 16384 MB, like it should. If I only have 2 in it sees 8gb, but only gives me 4gb physical to use.

This is a Windows issue then. Sounds like the hardware is properly recognizing the amount of memory installed.

Do you have access to a Live CD/DVD like Ubuntu or Mint Linux? If so, booting your rig with one of those can help confirm the likelihood of a Windows config issue causing this.

 

[COLGeek]

Did you perform a clean install of Win 10 Pro x64 or did you update from a previous version? If an upgrade, did Windows properly recognize your memory BEFORE the upgrade?

Also, have you installed the AMD chipset drivers (get directly from AMD)?

I don't but I can probably rip Mint and flash it onto a USB and boot it. Weird thing is this is a clean install of Windows that I've only had for about 3 months. My previous versions got screwed and ruined my whole drive. Any other lightweight suggestions to test this or is Ubuntu/Mint the best way to go?

BIOS looks completely correct to me. Do you see anywhere a feature called "memory remap"?

Install the chipset drivers I posted above before trying the Live CD/DVD thing (if not already installed).

Just did, gonna reboot into BIOS and search for that memory remap option and see if my MOBO has it, and reset my DRAM speed to automatic detection and see if it helps. If not I'll boot Mint off a USB.

 

[Shaun o]

Well I can see from your two picture links that the bios is indeed reading 16Gb of memory.

Have a look in your bios for any memory remapping option.
If it has one set it to enabled.

It can be listed as memory hole remapping.
If the board has the option to set memory to ganged or unganged memory mode try enabling the option or disabling it.

How many memory sticks are you fitting to the board in total ?

 

[Rogue Leader]

Memory remap does fix this (sometimes). And yeah Automatic memory settings.

There is no reason 4 DIMMS should not work in 16gb. I have a far older AM3 board, I used 2 different 8gb DDR3 1600 kits, and did not have this problem. Thats not the issue.

 

[mynameslars]

In BIOS atm and I'm not seeing any remapping options. I've got 4 sticks installed, from the same set. Any idea where the option may be located in my settings?

 

[Shaun o]

I was thinking if he was using a 2x4gb stick and a single 8Gb stick.
The conflict is between the motherboard not being able to decide what memory mode it should be setting it`s self to.

There would be a conflict between single and dual channel memory mode.
And as a result why windows only sees 8gb.

I`m going to look at the motherboard manual if no one else has.
see what it says.

 

[mynameslars]

Couldn't find a remapping option. Also, I've hunted through my manual and didn't really find anything helpful, but if you need a link I can give you one.
