Memory errors after hardware changes

[SGLATT]

Hello,

After installing a new mobo, PSU, SSD, and adding 2 more sticks of the exact same memory, I am getting occasional blue screens (especially when attempting to play WoW). I ran the test with the following results. What should I be seeing here?

Test 13 [Hammer test] Warning

Note: Your RAM may be vulnerable to high frequency row hammer bit flips. However the conditions needed to induce these errors occur only very rarely in normal PC usage, and so this should not be of concern to most users.

There is a fair chance the RAM is bad. See this page to start with
