Question Ram does not work together and by itself

[MicPotato]

I’m new to pc building and one of my ram sticks seems to be not working.

I have 2x8gb Corsair Vengeance LPX.

One of the sticks works by itself but the other doesn’t. The pc turns on and then goes on a loop. Then the monitor gets no signal, but the pc and the fans are still running.

I have a msi b450 tomahawk motherboard. The debug led for the cpu seems to be on. Is it a cpu problem?

Cpu : AMD ryzen 5 2600x

Also the pc identified both ram. I tested MemTest86 and it said no errors.

In single RAM configuration, does each slot on board work?

What do you mean by that? Is it on the bios?

 

[alexoiu]

I mean, if leaving single RAM installed, in slot 1 and starting the board, does it work? If yes, power off, move the RAM to slot 2, start the board, test. And so on with all 4 slots.

alright im going to try it now.

Ok.

All slots work. I tried it with the working ram. Should I try it with the ram that doesn’t work ?

 

[alexoiu]

If working in one of the slots, then it should be ok. Now try both RAMs, firstly in 1 and 3, then in 2 and 4.

I forgot to say on the forum, I put both ram on slot 1 and 2 when I first tried turning on the pc. Is that a problem? On the motherboard manual it says to put in on slot 2 and 4.

I had also installed windows with the one working ram.

 

[alexoiu]

No issue there.

 

[MicPotato]

No issue there.

I tried ram on slot 1 and 3 and it booted to the part where I put my password then the monitor just turned off. Slot 2 and 4 didn’t go to the sign in screen at all. So I guess that didn’t work.

Not sure what's wrong. An option would be updating the board's BIOS, and testing. Or returning the RAM kit, to be replaced.

What update should I do to the board’s bios ?

Is there anything I can configure on the bios ?

Nothing, if running it at default settings.

It implies a risk, and, since you're not familiar with the process, I would not recommend it.

Do you know what else to do ? I don’t think I can return it either, I got it from a third party seller.

One time both sticks worked and I went to system information and it recognized 16gb on my motherboard. But then it just turned off the monitor. (Fans still running and motherboard still working I think)

 

[alexoiu]

I suggest running it with single RAM, until able to test different RAM kit.

But what I don’t understand is that it recognized both ram sticks on bios. I also reseted cmos.

 

[alexoiu]

Hard to say what's wrong. A local pc shop might help.

Alright, thank you for all the help! But do you know what else I can do beside resetting cmos?

You're welcome.
Updating the BIOS. Check on youtube for some videos that show how to update the BIOS on boards similar with yours and, if you feel confident enough, go for it. Use single RAM when updating the BIOS and use the utility in BIOS, with the BIOS file saved on an USB drive. Do not do it from Windows.
