Hey

Are you saying that all 16GB of ram is recognized by both the BIOS/UEFI and WIndows 10?

Is this 2x8GB or 4x4GB?

I assume you're running Windows 10. Just a quick question. Have you tried running the simple windows memory diagnostic to see if it passes or gives you any insight?

Are you overclocked? More specifically, is your memory overclocked? Are you running XMP (extreme memory profiling) in BIOS/UEFI?

I don't feel comfortable telling you to buy ram for the sake of it without testing first but yeah if one of them is bad then yea buy a new set. Could risk buying a single stick of the same specs to save some money but not being in a set is taking a risk if not able to return the ram. Ram sold in kits are tested to work together.

Should i just buy new ram or somthing else?
I would give memtest (windows diagnostic) a try and see if it passes before considering that. You don't even have to open up the computer to try that. In my experience when a ram module fails the computer wont even boot.

You could also try re-seating the ram, cleaning the contacts etc. Also, most RAM has a lifetime warranty on it, so you could look into that too.

Try each individual stick one at a time. Seeming as it seems one of the sticks are bad, one stick should boot into Windows fine, while the other one should not. Once you have found out which one doesn't work, if it is still in warranty, contact where you got it from and see if it can be replaced. Otherwise, buy an exact matching stick (same manufacturer, same model, same speed and same size), or buy another 2x8GB and replace both of yours.

Should i just buy new ram or somthing else and when i play a game it says i dont have enough vram
Half the ram not being recognised properly can cause errors like that but so can limited space on the hdd/ssd windows is on affecting the pagefile (virtual memory ) from expanding.

How much space is left on your main drive and you haven't modified the pagefile size?

What size is it? Probably not enough and that's the reason for running out of memory errors.

When you get time, test the memory sticks as other's have also suggested. If one stick is bad remove it and return pagefile to self managed. 30gb free space should be enough to avoid memory errors.

Hold up. The other half of your RAM is hardware reserved. Seeming as you get VRAM errors too, it might be something other than bad RAM. Have you downloaded the drivers for the RTX 2070? If not, do that now and see how it goes. https://www.geforce.co.uk/drivers. Even if you do have them, then it would be worth trying to reinstall them.
Before you do this, however, is your RAM in alternating slots. If not, then move them so that they are in slot 2 and slot 4. It should be like: empty, RAM, empty, RAM.

I've tested them one at a time and they seem to work fine
