PC crashes when starting Dead by Daylight (2 Memtest errors)

[ToxicSk1ll]

So my pc has been crashing every time I start the game Dead by Daylight and it restarts. Ran Furmark 77° 120FPS and CPU Stress test no crash. Memtest 2 errors though. Can someone help me with these 2 errors?
Pc Specs:
i5-3550
RX 580 8gb nitro +
16gb DDR3 Ram
550W Power Supply
Errors:
[MEM ERROR - Data] Test: 7, CPU: 2, Address: 247CC88C4, Expected: BFFFFFFF, Actual: BFFFFFFE
and
[MEM ERROR - Data] Test: 8, CPU: 2, Address: 247CC88C4, Expected: 8C2EAF29, Actual: 8C2EAF28
Thank you for your time
