my pc keeps freezing, is this a ram issue?

i built my new pc for christmas and ever since i built it it has frozen on random and not even blue screening, i doubt it would be my motherboard or cpu, i have tried re seating my ram in different dims on my motherboard but the problem still persists, my pc can go hours without crashing and the longest its ever went is 9 hours and then it suddenly froze, i was thinking that it could be compatibility with ryzen as some ram as issues working with ryzen, when i was ordering my ram it didn't say that it would be compatible with ryzen but i thought it would work with ryzen, and i cant just take out a stick as i only have one because i was on a budget at the time but i plan on upgrading to 16gb as soon as i can, if it is the ram then i can easily return it because of warranty.

heres my pc specs if you need it

amd ryzen 5 1400 cpu

gtx 1060 6gb

Crucial CT8G4DFD824A 8 GB ddr4 (https://amzn.to/2RrD7Zh)

gigabte a320-s2h (https://amzn.to/2Fdo2ns)

evga 500w 80+ (https://amzn.to/2Qve3vW)

and i have a 240gb kingston ssd for windows and a 1tb wd hard drive for games

its worth mentioning that i will be running memtest86 for a full day just to check if it is the ram.
