I have been running my system for about six months, just recently was looking at System Monitor and realised that it was only using 7.8 GB of RAM... I have 16GB installed...

So... I read a lot on the forums, but none of the help seemed to fix it.

I could be a hardware fault, but because the parts are new. I'd like to try everything before opting for that.

So I have a ASRock 970M PRO3 mATX (http://www.asrock.com/mb/AMD/970M%20Pro3/?cat=Specifications) installed, it takes "Max. capacity of system memory: 64GB..."

I have x2 sticks of G.Skill 8GB DDR3-2400 (http://www.gskill.com/en/product/f3-2400c10d-8gtx), the ASRock takes "Supports DDR3 2400+(OC)/2100(OC)/1866(OC)/1800(OC)/1600(OC)/1333/1066 non-ECC..."

My OS is Ubuntu 16.04 64-bit.

... so I took apart my computer, I made sure it was in the right slots. Happens that if I put it in the wrong spots the computer fails to load, so that worked well. I have a mATX so I tried everything before I had to do that... because, the insides of a mATX can be a bit squishy https://ubuntuforums.org/images/smilies/icon_smile.gif.

So... in accordance will all the other posts on this issue. I have...

cat /proc/meminfo | grep MemTotal

Mem Total = 8147216 kb
Which is 7.8GB which is what System Monitor is also showing.

sudo dmidecode --type memory

# dmidecode 3.0

Besides that, I have no clue rather than just reading and following instructions -.-.

Please help :).

Thanks in advance...

Edit: So far, changing their slots hasnt worked. Are currently in the correct A2/B2 slots as written DDR3 2400 should be located in.

Edit: Checked physical RAM's sticker, says each stick is 8GB and purchased from a company not an individual seller. My invoice says their code is F3-2400C10D-8GTX. The other two items received work well, but I'll email them and see what happens.

The first thing to do is to check the memory status in the BIOS. You may need to configure them differently to have them show up.

Memory modules are often "double-sided," where they are pairs of banks of memory chips. Systems only seeing half of a stick of RAM is an old old problem.

It is usual for Linux to report less memory available than the size of the physical memory that exists; it needs some for itself, and so that memory is no longer available for anything else.

Edit: your output is showing that it's only found half of the chips in the modules in banks 0 & 1, and it's running them at half speed, and it's not detected any modules installed in banks 2 & 3. That definitely looks like a hardware configuration problem or an incompatibility between your RAM modules and your motherboard's memory controller.

Edit: the website you linked for the RAM specifications confirms that each module is arranged as 2×4 GB. Some motherboards require that the slots are filled in particular ways, say banks 0 and 2 for one configuration. Your motherboard's manual should tell you more.

Edit: from your motherboard's manual:
Please install the memory module into DDR3_A2 and DDR3_B2 slots for the first priority.
If you adopt DDR3 2400/2100 memory modules on this motherboard, it is recom-
mended to install them on DDR3_A2 and DDR3_B2 slots.

Also, crucial.com's parts checker is a very useful tool for establishing memory module compatibility.

Edit: you say you should have 32 GB installed, but two of the sticks you linked to would be 16 GB.

You've got two 4GB sticks. I don't see an issue here, other then you're confused about what you bought, or perhaps received the wrong product.

I bought them from a reputable wholesaler. The stickers on the side say that they're F3-2400C10D. I emailed them to ask. But still doesnt explain why their being used at 1333 even if they are F3-2400C10-4GTX.

But you are right regardless, the sticks are 4 GB. I took one out and just loaded one. Its coming up saying that they are 4gb each.

Which is weird, because the motherboard loaded them both even though they were in the wrong spot... O.o.

I got super excited when I read this.

Because they were put in two slots next to each other, my bad for not noting that in the manual! Ffs. Super excited, pulled them out, reslotted them in Slot 1/3. Still not reading them. I took them out, did the other, Slot 2/4. Still only registering 7.8GiB.

Yea totally assumed they were 16 GB, but it "makes up" 16GB, yea they are two 8s, memory, even the link i had saved it as when I purchased them correctly said 8 :). I didnt recheck their ram usage, I went from memory. I half remembered correctly, that I had purchased "16 gigs" just, they are combined not separated into that amount.

https://au.pcpartpicker.com/list/ is what i used yea... to determine compatibility.

Yea it says it here right. This is the dmidecode after putting the RAM into the A2/B2 proper slots that it says are right for DDR3.

So A2 and B2 on that list are both saying their running at 1333... but the actual ram is 2400... so even though its saying on it, the parts number is 4GTX, it still says 2400 in that same sentence. So still makes no sense, even if they are 4GB sticks (which I dont think they are), for them to be running so slowly... if thats where I'm reading correctly that you are taking that data from O.o :).

So yeah... I sent an angry email to the distributor and asked for a refund. Thanks for the help guys, much appreciated.

I hope for the company's sake that someone else put the wrong stickers on it... because now... im thinking of submitting an angry consumer report to the ACCC about it (who will investigate the companies wrong doing)... -.-. Sigh...

A memory bus speed of 1333 MHz would be right for DDR3-2400: https://en.wikipedia.org/wiki/DDR3_SDRAM

It's this part
Configured Clock Speed: 667 MHz that makes me think you might still need to check the BIOS settings. I could be wrong, though.

It's Double Data Rate , so 1333 * 2 = 2666

As for 7.8 vs. 8GB, a little bit of the addressing range is probably being used for hardware. It's nothing to get in a twist over. Double check exactly what you ordered before shooting off angry e-mails and don't whip out the outrage card before it's absolutely necessary.


It's this part Configured Clock Speed: 667 MHz that makes me think you might still need to check the BIOS settings. I could be wrong, though.

I believe that is just the conservative SPD setting that the RAM comes configured with for compatibility purposes. Motherboards that support XMP (which the OP's does) should clock the RAM at the max rated speed without tweaking. As for the slot placement, it probably doesn't matter except for purposes of dual-channel operation.

Again, I don't see an issue here except consumer confusion.
