View Full Version : CG8890 Not Overclocking via SPEED Button or AI Suite II

I am stumped on this problem. My CG8890 will no longer overclock beyond the base frequency of 3.8Ghz. I can use AI Suite or the SPEED button and the on-screen display says 4.0Ghz and 4.2Ghz and the case opens up and the LEDs go red but the frequency is not going beyond 3.8. When I OC'd the system in the past the fans used to become quite a bit louder etc but it just stays quiet now. My GTX 690 also used to get quite loud but stays silent now.

I have done a full system restore but still not luck. Can anybody please help? I use the system for Flight Sim which is CPU/GPU intensive and just not getting the game experience I used to.

Many thanks for your assistance in advance.
