Achieving a low Time Spy Score on a 6900XT and 7800X3D
Achieving a low Time Spy Score on a 6900XT and 7800X3D
The GPU only uses up to 255W, which matches the default setting in AMD software. It seems you haven’t adjusted anything, and that’s the normal behavior. The Windows settings also reflect this limit.
It required some work, but I discovered the official TDP for the XFX 6900XT SWFT 319 graphics card is 300W. I recalled that XFX cards typically have dual BIOS configurations—quiet and performance modes. The BIOS switch is tiny and situated close to the PCIe power connectors. Ensure your computer is off, then try flipping the switch to the other position. This might unlock the full capabilities of your card. Checking your AMD software screenshot, click the Manual Tuning - Custom button at the top right to access the sliders. The power limit should have a +0 or 100% slider. Feel free to share a screenshot if you'd like us to review your settings. Generally, adjusting the sliders shouldn't harm the card, but it's wise to verify its performance first before making changes.
You're exploring the AMD software settings and seeing some interesting trade-offs. The power limit slider only goes up to +15%, which leads to a TDP of 295W even under full load, causing louder fans and higher temperatures despite staying within specs. The clock speed increases with higher power, but your CPU's Time Spy score remains low. Whether you should undervolt depends on balancing performance and stability—consider it if you want better scores without overheating.
It lowers the voltage applied to the processor, which cuts power consumption and heat generation. Reduced power often leads to cooler temperatures and allows the CPU to run at higher speeds for extended periods. The drawback is that excessive undervolting can cause instability, resulting in crashes even though it doesn’t harm the hardware.
Adjusting the BIOS key to the opposite of the power connector changed the display. The initial version appeared as shown, while the updated version looks like a different BIOS release with identical clock speeds and no overclocking options. Still, I’m not sure what XFX smoking means.
I believe the BIOS labels are cut off in your screenshots. The first one ends with _A0_S while the second is longer and broader. The complete name might be hidden by the window’s right edge. Regarding Silent and Performance modes, they sometimes use a different fan curve, though the rest of the BIOS remains unchanged. Since you already have GPU-z enabled, can you navigate to the Sensors section and run a stress test on your GPU? I’m mainly looking at total power consumption and the PerfCap setting.
