Pc has and recognises 16gb ram but windows only uses 8

z2x1 · Jul 29, 2023

Recently bought new parts for a build and installed windows 10. Everything works normaly but when I booted to windows and checked task manager and resource monitor it said that 16gb were installed and only 8gb are used and the other ones are system reserved(task manager says so). Tried somethings like updating bios to 5.90 (Asrock doesn’t recommend any newer for r5 1600 af) and ryzen chipset drivers.
system specs:
r5 1600 af
asrock ab350m pro4
ram one both sticks are samsung but from different sets one has an hp sticker but both are 2666mhz
ssd nvme 120
sata 256
gtx 1650 super pegasus
psu fsp 400w.

Try to boot with one stick at a time, you may have a faulty stick.

Try loading the computer with tasks demanding enough that it needs more than 8 GB of RAM. Have the system monitor running at the same time.

Try installing them in DIMM_A1 and DIMM_B1.

after troubleshooting adn putting the sticks one on every slot the samsung with hp boots just fine, but the only samsung doesn't show picture and after a little bit the pc shuts off and tries again but its wierd that it still recognises the ram and someting I see in the samsung is that it is a little bit bend

Looks like a component may have broken off.

Best to buy a new set so they match, as I mentioned before a 2x8 GB DDR4 kit is cheap these days.

z2x1 · Jul 30, 2023

well i dont have any spare money so im just gonna buy another stick

with same speed

dont whant to set it"' · Jul 30, 2023

Try and get same model as your good one, see spec on the label on ram dim.

Good luck on finding a matching samsung ddr4 stick cheap....

In my country it's cheaper to buy a new other brand 2x8GB kit....

Since no-one managed to spot the obvious, I guess I have to point it out, as it's in one of the OP's pictures.

8.1 GB of RAM is hardware reserved. This is some dumbass thing Windows does sometimes, so the RAM appears to be just fine, it's just that Windows won't let you use it.
The only way I have found to solve this, is to re-install Windows. There are supposedly some other ways that might work, but haven't for me when I had this issue some years ago.

I've had the same on a config where one stick of RAM was bad. It's not necessarily a software issue.

I don't think Windows is the issue, when OP says :

But you can read what it says on the screen no? That means the RAM is working, as the system is detecting 16 GB.
I've had this exact issue and I'm not alone.

As I've said, I've had 8GB of harware reserved on a system where a stick of RAM was bad.

One way to clear this up is use a live distro, if it's just an OS problem the RAM should show up on at least one of the many Linux options out there!

Looks like a hardware issue

This and the missing component

Is this element not sufficiently fused so that the absence of a single resistor renders the module inoperable?

Shrek · Jul 31, 2023

I'm guessing it's a capacitor

Dr. Dro · Jul 31, 2023

That RAM stick's visibly broken, you could probably fix it by resoldering that resistor but, as mentioned before RAM is very, very cheap these days. Especially low end RAM. Might as well just buy another kit and be done with it, even if on a very tight budget. A nice 32 GB DDR4 kit can be had for less than $50 these days.
