The Rx470 8gb outputs show a byt Gpuz indicating it is clocked at 0 MHz
Hello, I have a graphics card issue. I bought an RX470 with 8GB only in DVI version. The task manager doesn’t recognize it (Device Manager shows error code n.43). It shows display output and fans spin, but performance is very low, possibly worse than the integrated GPU. I’ve tried flashing the VBIOS, which just reports a system ID mismatch. I downloaded different drivers but they keep showing errors—none are installed or working properly, even though I can see the version in TechPowerUP GPU Utility. I also disabled the integrated graphics and still couldn’t get it to work. Any advice on why this happens or how to fix it would be greatly appreciated. Thank you!
did you attempt this vbios?

use the uninstaller, reinstall amd drivers then try pixel patcher

Standard after-mining card tailored for mining purposes. Many of these passed through my setup after the Ethereum project ended. They are typically sold at low prices in their original condition. I recently acquired 12 RX570 8GB units on the FB marketplace for less than $300, all equipped with custom mining firmware and dust, though there were no other problems. From my perspective, mining these is safer than gaming because it reduces thermal cycles and load fluctuations that can accelerate electronic wear.
To determine the correct BIOS, inspect the memory chip markings. Polaris GPUs rely on DDR5, but various chips need distinct voltages and timing settings stored in the BIOS. Common options include Samsung K4G80325FB or K4G80325FC, Micron MT51J256M32HF, and Hynix H5GQ8H24MJR. These four models are not compatible with each other and can all be found on the same card type—so it’s important to identify which one is installed in your system.
Replacing thermal paste and pads after removing the heatsink is advisable. It would also help if you shared the manufacturer name and provided clear photos of the PCB front and back, so I can guide you to the appropriate documentation. Beyond memory configurations (which may be the main concern), the BIOS also manages features like TDP, current limits, thermal design, and VRM settings that influence performance. I’d want to ensure a proper flash file is available before proceeding.
Additionally, your motherboard’s BIOS configuration matters—some AMD boards require enabling “Above 4GB MMIO” or similar settings for optimal operation. Consider adjusting that setting as well.
Thank you, I successfully reflashed the BIOS using the command prompt and everything is working properly now. I had to be careful with the memory types, but I just selected Samsung even though it indicated Hynex memory since they are more general.
Great news. Was it about the memory chips themselves or just through the software (which reads the BIOS)? I doubt the card would function with Hynix memory on the board and Samsung configurations in the BIOS. Even the two Samsung 1GB chip types can’t share their settings…
It only mentioned in the GPU Z program that the card wasn't opened, but it actually worked with the BIOS stating Samsung and Micron. I was surprised it didn't brick it, haha.
