Ram hardware failure

[Klimentiy Kulapov]

Hello.

I was testing my system memory and got a warning 20 seconds after the test started, I also recently got a blue screen twice with an error of memory management. And all of above started when i bought the second ram module Kingston ValueRAM [KVR16N11/8] , btw the first one is exactly same. Idk what to do, I`ve already tried to reinstall them and it gives same result.

My motherboard is GA-H81M-S1 rev 2.0
