RAM not being fully used. 16gb show as 8gb

[crankyandchaco]

Greetings citizens,
Bios: Latest
CPU: Ryzen 1700 stock speed with a corsair h60(2013) in push and pull with 2 corsair sp120s
Motherboard: Msi b350m Gaming pro
Ram: Corsair 8gb ddr 4 2400 x 2 CMK8GX4M1A2400C16
SSD/HDD: 1x m.2 samsung 256gb, 1x kingston ssd 128 gb
GPU: Msi gtx 1070 gaming x 8gb
PSU: EVGA 600 BQ, 80+ Bronze 600W, Semi Modular, FDB Fan
Chassis: Phanteks Eclipse p400S
OS: windows 10 pro 64bit


I recently realized that even though I should have 16gb it shows 8gb being hardware reserved and nos usable for anything.
Is there a workaround this?

If I were to change those sticks to this: CMK16GX4M2A2400C16 would my problem be solved?

This is the msib350m Qvl: https://www.msi.com/Motherboard/support/B350M-GAMING-PRO#support-mem-12

I dont want to buy a new one in vain, if possible id prefer to use the ones I currently have.

Any help is valued!

Are you on the latest BIOS update for your motherboard? As this is a troubleshooting thread, you;'ve forgotten to include your full system's specs. List them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Rather than change and/or spend more resources, lets see if we can work with existing hardware, shall we?

It is possible that:

- one of them is not fully seated (reseat both sticks firmly all the way)
- mobo doesn't prefer the combination of slots you used (use 2 slots for dual channel config as per your mobo manual)
- try CMOS reset
- BIOS might need an upgrade for better RAM compatibility (if you are already at the latest version, then obviously you cannot do this)

Motherboard: Msi b350m Gaming pro = Only has 2 slots
Both fully seated
CMOS reset: unsuccessful
Bios: Latest

Try and find the one that is not showing up by using some software that shows what slot the RAM is in. Take out the stick that isnt showing and swap slots with the one that is showing. If the issue follows the stick that'd suggest the stick is broken, if the same port doesnt show a stick its probably the RAM port on the Mobo.

Yeah, try each of them individually. There is a slight chance that one of them in not working properly.

BTW, are they both identical in every way, purchased as a dual channel kit or....?

They are both iddentical, but purchased individually. They both work when placed in SLOT A1 when either is place on B1= NO boot.
If I place both on anything other than factory settings in the bios it wont boot.
They are both recognized in: The bios, speccy, cpuz, hwmonitor, yet task manager says 8gb are reserved. Both sticks have been individually tested on Slot A1 and both work on slot 2 neither will boot the pc

Tough call. Since they were not purchased as a kit, there is a (very small, but still...) chance that they simply don't work well in tandem. There is also a (very small) chance that the 2nd slot is not working properly or not getting a good contact.

But getting a new RAM kit (or mobo) is kinda expensive and pointless just to be able to prove it.

It would be easiest to test the memory in a different mobo to check whether it works or not. Or even better, just borrow a different set of sticks to try in your own mobo. That's the only thing that looks viable to me at this point. If a different set of sticks works in your mobo, you know that it is RAM. If it doesn't... well, looks like it is the mobo to blame.

Memory is guaranteed in the form sold. Combining multiple modules sold as singles have no guarantee to be compatible together. All compatibility testing will have to be done by you with no guarantees.

Just google the make and model of your RAM modules and ask the question as to whether they can be dual channelled. Im sure someone else has had this issue before. Failing that someone may be able to tell you right here if you list us the Make and Model of your modules.

EDIT: Having had a look at the model provided, it does not look as though these can be dual channelled. I'd recommend selling that module and buying a dual channel kit of the same kind.
