1. Please run Prime95 again, but use the Small FFTs and the In-Place large FFTs options. Run Prime95 at least a few hours with each option.
2. Please open Furmark and try to remember what options were checked, or run Furmark again according to the instructions below in the post. I believe that the standard options should be edited a little where in the settings all options should be checked except for 'Dynamic camera', see the tutorial for the exact configuration.
6. The best place is the BIOS.
Run Furmark to test your GPU. Furmark tutorial
Run Furmark for around 30 minutes
Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if temperatures rise too high
When finished, make a photo/screenshot of Furmark and post it.
In Furmark you can find a tool called 'GPU-Z' (if you want to install GPU-Z is up to you), when GPU-Z is open click on the 'Sensors' tab, on this tab you can monitor
- the frequency of the GPU,
- the GPU memory clock,
- the temperature,
- the power,
- the load on the GPU,
I would like you to make a screenshot of GPU-Z after you have either cancelled Furmark for any reason or Furmark is finished, post this screenshot in your next reply with the result of Furmark.
