7.95 RAM usable from 16 GB

Baigtas · Jul 6, 2020

ello,

I have 16gb 2x8 DDR4 "HyperX Fury Black 8GB DDR4 3200MHz CL16" Memorie HyperX Fury Black 8GB DDR4 3200MHz CL16 - PC Garage
Nvidia Geforce GTX 1660 TI 6GB GDDR6
ryzen 7 2700x cpu
B450M DS3H-CF MOBO Bios version F41 - AMD AGESA COMBO - AM4 1.0.0.3
Windows 10 version 2004 OS Build 19041.329 ( just installed today to see if the problem will be fixed)

Does anyone know why the windows is using only 7.95GB of 16GB ?
In bios it shows both sticks, in cpuz it shows 16GB but the windows is using only 7.95.

I tried to check and uncheck maxim memory in msconfig, i tried switching the slots on the mobo, and couldn't find any settings in bios about reserved RAM in easy mode or clasic mode.

Link to photos of the task manager, cpuz, system and BIOS:

Don't mind the XMP profile. i tried to activate it to see if it change something and forgot to turn it off

Hope someone can help me :)

It's being utilised by your hardware for I/O mapping.

What i can do to use all my ram ?

Yes, your graphics card has 6GB GDDR which needs to be mapped to RAM, hence why the amount of RAM which is reserved for hardware is so large. You also have your BIOS which needs to be mapped, along with any other peripheral devices.

You can check your BIOS settings to see if it has a setting for memory-mapped I/O or memory mapping.

I'd suggest there's a 'bad' driver/firmware/Bios involved, my rig (E3 Ivy Xeon, Z77 ITX, 16GB DDR3, 6GB GTX 1060, 3x ~256GB SSD, 2x 2.5" HDD) has no such issue on W7 with a 6GB GPU.

Could you check the memory tab of resource monitor?

I couldn't find anything in the bios that could use ram or i don't know where to check

The installed RAM was not seen on the motherboards Qualified Vendor List (QVL).

Please swap test RAM modules on the QVL:
B450M DS3H (rev. 1.0) | Motherboard - GIGABYTE Global

Upgrade the BIOS: 41 > 50
B450M DS3H (rev. 1.0) | Motherboard - GIGABYTE Global

I don't have other RAM to test.

I will try to update the bios and i will come back with the results

One more question, it is ok to update to version F50a directly from version F41 ?
I never updated a bios before

zbook · Jul 6, 2020

When upgrading the BIOS:
a) verify the motherboard version
b) upgrade the BIOS to the most up to date non-beta BIOS
c) BIOS versions can be skipped unless there is specific information in the intermediary BIOS versions

F50a was not seen for revision 1.0

The only thing that changed is that in task manager it no longer saying 7.9 and it says 8

I agree. There should not be nearly that much stuck in Hardware Reserved. Sorry, but mapping does not work that way. I have just 42MB in Hardware Reserved
and my graphics card has 4GB of GDRR5.

I have 32GB installed, and as can be seen, with 7.2GB in use, I still have 25.4 available.

When excessive Hardware Reserved is seen, as satrow noted, it typically means you have a faulty hardware driver. You might try booting into Safe Mode and see what happens. To enter Safe Mode in Windows 10, go to Settings > Update & Security > Recovery > Advanced startup, click Restart now. After PC restarts, in Choose an option menu, select Troubleshoot > Advanced options > Startup Settings > Reset. After second restart, in Startup Settings menu, select Enable Safe Mode (usually #4) to restart a third time into Safe Mode. See https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

And/or you might disconnect all extra hardware and leave just your boot drive, keyboard and mouse and see where you are.

High hardware reserved is seen with mismatched RAM and when using RAM not on the QVL.
Consider swap testing or purchasing RAM on the QVL.

And what exactly do i have to do in safe mode ? what should i check.

satrow · Jul 6, 2020

The single RAM stick isn't QVL'ed by Gigabyte or HyperX, that might be the problem. What does Resource Monitor show with a single stick installed?

Frankly, I'm not sure. If all your RAM is being properly identified and used in Safe Mode, that would tell me something loaded in regular mode is incorrectly using the RAM.

Safe Mode starts Windows using most default settings with a limited set of files and basic drivers. If your problem doesn't occur in Safe Mode, it means the default settings and basic drivers aren't the problem. If the problem still happens in Safe Mode, it might help us narrow the problem down to a specific piece of hardware, or it might point to a native Windows file.

I just tried, the problem happens in safe mode too...
