I built an AMD FX-9590 System almost 1 year ago, and I had no problems for almost one year.  Then I started having a ton.



Random Restarting

The first issue was that the computer would randomly restart itself.  After going through a ton of debugging steps including reseeding and replacing ram the root cause of this was due to overheating.  I have a corsair water cooling system and dust had built up on the radiator unit and was causing the radiator not to cool down.  The radiator was so hot, one could not touch it with their bare hands.  A can of air and dusting that off, seems to have resolved that issue.


System Instability

About a week or two later after the random restarting, the computer would just lock up.  Sometimes it would lock up 5 minutes after a reboot, other times it would make it a whole 4 or 8 hours.  Even sometimes a full day or two.  I tried a bunch of things, but what really seemed to work was the following.  Please note, I did all these things at once, and since they seemed to work, and I don’t care to play around with the machine anymore, I am keeping all of these things set!  So i don’t know exactly which specific setting or set of settings fixed it.


  • AI Tweaker-> AMD Turbo Core – Disable
  • Disable Cool N Quiet
  • Auto Boost – Off
  • C1 and c6 states – disabled
  • Installed, and mounted a side case fan, that flows directly onto the northbridge heatsink on the motherboard.

Since I have done the above, the system has been stable, for 4 days now, and has not locked up once.  I am writing these to hopefully help someone else.  Many of these tips I found on tom’s hardware with people having the same issues – so big thanks there!

UPDATE: the lock ups came back. I wound up re pasting the cpu with new thermal paste and cleaning out all fans and dust from the radiator. I have not had a single lock up since.
