GPU fails to function when using PCIe X16 configuration.
GPU fails to function when using PCIe X16 configuration.
AI tweaker settings for voltage reference Ram appear similar to Hynixes. Increasing BCLK strap to 125 may improve CPU OC ability. Consider trying 4.5 or 4.6 D. Precise values are uncertain due to unknown behavior of X79 during overclocking, but an OC method is possible. Set BCLK to 125 and keep strap at auto; board selects optimal strap. Adjust CPU and RAM multipliers accordingly—current settings around 35x for CPU, 2500 (20x) for RAM. Keep other timings like CL12, command rate/mode 2T, TRFC 450. Once stable, try 2666 for easier posting. For higher RAM multi, set to 24x (should show 3000 in menu). VDCSA can be raised slightly, but VTTV should stay at 1.45V max. If no post, increase VCCSA and VTT by 0.05V up to 1.65V, depending on stuck state.
I upgraded to an RTX 2060 Super and it functions smoothly in x16 without any issues. The previous GTX 780Ti caused the problem.
