Only 1 RAM Stick working

[TimTomTwo]

Hi,
so now I got my replacement, after the boot-loop problem, but now my system only works with one RAM stick, instead of two.
The weird thing about this is, the board and even AIDA64 recognize the second stick, but Windows TaskManager and the BIOS tells me, that only 8GB is in use...
And yes, I tried booting with each stick separately and it boots to Windows and all just fine, so both sticks seem to work properly.
Got anybody any idea?

System:
Crosshair VI Hero
BIOS 0083
Ryzen 1800x
HyperX DIMM 16GB DDR4-2666 Kit (HX426C15FBK2/16)
Windows 10 Home

New ROG strix B660-A motherboard Intel Core 12th gen i5-12400F LGA1700. RAM is Team Group T-Force Delta 2 DDR4 CL 16-18-18-38 1.35V. Will not even boot with two module but will boot with one in DiMM B2. I tried the other module in B2 it worked as well. I have 4 DiMM slots only one works cant get answers from ASUS surprisingly, This is my 5th build and always use ASUS boards this is first problem Looks like someone from asus would help I sent problem to intel and they did email back and insulted me with things to try that are obvious and i already tried. Guess ill send everything back and start over with different parts.

TimTomTwo - your memory, all of it is recognized correctly based on CPU-Z... even the Windows is seeing 16GB...
Something is using up, reserving quite a bit amount - you have to figure it out which software...

You really think it's software-related? It's happened to multiple people and I am on a 1 day old install of Windows, and it does say "Hardware Reserved" in the task manager for whatever that is worth. Wouldn't it be as simple as trying safe mode to rule out software issues?

Hi,

it's definitely NOT a software bug. Because it even shows me 8GB of used RAM in the BIOS (or UEFI or whatever). And in the UEFI SPD info screen, I can see both sticks of RAM, too...

Try this, Type Advanced system settings in search box , On the Advanced tab, under Performance, click Settings, Click the Advanced tab, and then, under Virtual memory, click Change. Clear the Automatically manage paging file size for all drives check box save / apply changes & restart your pc, check (Task Manager/Performance/Memory) & see if Win 10 has the 16GB of Ram available, If it works turn Auto back on & restart again, worth a shot.

I tried disabling the paging file this way and it didn't fix my issue unfortunately.



Sorry if it seems like I am hijacking OP's thread, it's just that we seem to have the exact same issue in the exact same way - albeit it with different RAM kits.

I hope that if nothing else, the 1.0.0.6 BIOS can be our saviour.

Try adding a custom paging file, also when restarting, restart from a cold boot, turn computer off, turn off power at psu or wall, wait 30 seconds or until all led,s r out, then restart.

Gave it a go (set manual page file size of 2048-2048), didn't work. Made sure to clear static by unplugging the cable and mashing the power button for a while.

Do you have GPU-Z installed? I'm curious how much vRAM it's showing, just a thought.

Better yet, open device manager, click view > resources by connection, and open the memory node. Is your video card listed there?
I'm not seeing anything in the BIOS like a frame buffer that might be doing it.

That section on device manager isn't the easiest thing to read. But it should show what is using hardware reserved memory. I did read where people were getting this behavior (on older systems) when they sticks were in slots that did not work with their configuration as well. Think that's been pretty well covered here though.

Did you ever get a chance to test with a different kit?
