Compatibility
| Slot | PCI Express x16. Check di exact link rate on top di board. |
|---|---|
| Power | Na 65 W dey the sheet. The power plug na detail wey dey depend on partner card. |
| Case | Length, thickness, and slot count dey vary by partner cooler. Measure di case, no be di SKU name. |
Di SKU name no be cooler, length, or power plug. Read di exact partner card before you buy or install.
Fit power connectors well well make dem enter. Loose high-power plug fit over-hot. Na connector problem be dat, no be reason to believe say di GPU don die.
Driver packages from previous GPU na common thing wey dey cause crash. Clean-install di current vendor package before you change hardware.
No display after installation
Plug di monitor enter di GPU outputs, no be motherboard, except say na integrated part. Black screen wey fan dey spin na mostly power plug, seated PCIe card, or di display cable.
Driver dey install, den games dey crash
Use di vendor package wey match dis generation. Driver wey remain from previous GPU na common cause.
