You are correct. The real time VTT is not available in the BIOS, so the board isn't monitoring it. I have the Bclock set to 166, so I set the VTT to 1.1v, and continued stability testing of my overclock, and all seems fine after four hours of IBT.Martin said:Even if your machine allows to adjust VTT, it doesn't mean that it can monitor the actual VTT voltage. If it would, you should see the VTT voltage in the BIOS System Health screen. I assume, it's not there.
