Testing for faulty RAM

[matio57]

Hellooo,

 

I have been suffering from random PC crashes only when gaming for a while now. They occur in any game (AC: Unity, PUBG, even DotA 2 has started crashing :'( ) and causing instantaneous reboots. 

 

I have identified it in windows event log as a kernel power 41 error with bug check code 0 which I believe means that it is a hardware fault. BUT I don't know how to identify which part. 

 

So I want to start with what would be the cheapest to replace; memory.

 

My PC is a Ryzen 5 1600, GTX 970 Asus Strix, MSI B350 Tomahawk, 550W EVGA G3+ Supernova and 2 x 4Gb Corsair Vengeance LPX 3200MHz.

 

Reading around I've seen debates on MemTest64, MemTest86, Memtest86+, Ram Test (which is paid), and others. 

 

Could anyone help me by advising what to use or point me towards a good guide for fully testing RAM?

 

Thanks in advance!
