On some motherboards, you may need to adjust "PCIe Speed" settings (setting them to Gen1 or Gen2) in the BIOS to improve stability with this specific bridge chip. Where to find related ASMedia Drivers
Frequent blue screens (BSODs), system freezes, or sudden disconnects of your PCI expansion cards.
If you're unsure whether your system uses the ASM1083 bridge chip, you can identify it by its hardware identifiers:
The ASM1083 is an onboard chip. Visit the website of your motherboard manufacturer (ASUS, Gigabyte, MSI, or ASRock). Search for your specific motherboard model. Look under the "SATA" or "Chipset" download categories. asmedia asm1083 driver windows 7
