Recently my brother has been having issues with his PC randomly turning off and restarting. We tried a bunch of things but I ended up wanting to test the Ram. I ran the Memtest86 with both of his sticks in and received 330~ errors. We took out one of the sticks and it received 0 errors then when I tested the other stick it received 330~ through the 4 passes. I do not really know what the errors mean so I'm curious if one of the sticks is bad.

Here is the basic PC Specs:
Intel i7 8700k
Asus Prime z390p
8x2gb DDR4 3000 G.Skill Riptide V
GeForce RTX 2060

Here is the Errors recorded from pass 4 of the memtest:

From what I read online it looks like a bad ram stick to me. But just to be sure I went and made sure that my motherboards XMP was set to the correct mhz, timing (16 - 18 - 18 - 38 ) and voltage. We have tried wiping and reinstalling windows as well as making sure all his parts were clean in his pc. The fans all run and the heat monitor doesn't show any excessive heat.

Is there anything else I should check?

And I have a question about replacement ram (if the ram is infact bad), I plan to keep the good ram stick in the system. I just need to match the Old rams Timing, MHz, and Voltage right? It doesn't have to be the same stick? And would getting a total of 3 ram sticks in my system be bad? or should I stick to just replacing the single stick and leaving it at 2 sticks?

EDIT: We removed the bad stick and left the good stick in the system and got the same error where his PC stutters then goes black before restarting.

Anything I should check for faults?

"I plan to keep the good ram stick in the system. I just need to match the Old rams Timing, MHz, and Voltage right? "
in theory, in practice matching RAM by yourself is like gambling at a casino. the odds are bad.

there are reasons that they factory match sets.

both sticks should be from a matched set unless you want to take a solo course on memory matching. its a long class with no teacher and no degree (minute adjustments and testing of each in pursuit of stability), matched sets are way way faster and guaranteed by the factory

I see, I will end up probably picking up 2 sticks and see if they work together. But otherwise ill switch the set for the new one. Thank you

From what I read online it looks like a bad ram stick to me. But just to be sure I went and made sure that my motherboards XMP was set to the correct mhz, timing (16 - 18 - 18 - 38 ) and voltage. We have tried wiping and reinstalling windows as well as making sure all his parts were clean in his pc. The fans all run and the heat monitor doesn't show any excessive heat.

Is there anything else I should check?

And I have a question about replacement ram (if the ram is infact bad), I plan to keep the good ram stick in the system. I just need to match the Old rams Timing, MHz, and Voltage right? It doesn't have to be the same stick? And would getting a total of 3 ram sticks in my system be bad? or should I stick to just replacing the single stick and leaving it at 2 sticks?

EDIT: We removed the bad stick and left the good stick in the system and got the same error where his PC stutters then goes black before restarting.

Anything I should check for faults?
Have you Memtested the so-called good stick by itself?
If this is your brother's PC, can you swap out the 2 sticks of his RAM with a matched pair from your PC? If the problem still exists, then you'll know you have to look elsewhere.
