From 3.4 to 3.8 GHz is done by a CPU boost feature. 3.8 to 4.2 GHz is taken care of by MSI Afterburner. The OC is VERY stable (all sorts of stress tested passed) and I have used it since September 2012 without issues.
- I use 'Nvidia Experience' software to manage/update video drivers. Is this enough?
- Will try that!
- Since I have found a solid OC after much tweaking and testing I'm not that keen to change it.
- Fans are running according to a set temp curve. I monitor all temps (both CPU and GPU) so I know heat isn't an issue here.
- VSYNC was disabled when last CTD happend.
- Will try that!
- I have gone down from Ultra to Very High. I have a solid framrate and CPU usage is around 55-60%. Changing down didn't change anything.
Thanx for your feedback. I'll try again with suggested tips and check what happens.
