Describe your problem. List any error messages and symptoms. Be descriptive.

RAM problems. Getting "He's dead, Jim" in Chrome and a PAK error in cs:go, both of which are indicative of fked up RAM

List anything you've done in attempt to diagnose or fix the problem.

I have ran memtest86. When I run both sticks together, I get errors, but when I run them by themselves, I don't get any errors.
I have tried running both sticks in slots 1 and 3 which threw errors, and I have tried each stick in both slots 1 and 3, none of which threw errors.
What is the next step in troubleshooting?

Try clearing CMOS.

If still have problems, increase DRAM Voltage to around 1.55 V.
