## Compatibility

| Socket | FCLGA1567                                                                                       |
| ------ | ----------------------------------------------------------------------------------------------- |
| Board  | Shared socket no mean automatic compatibility. Check di motherboard CPU list and BIOS revision. |
| Memory | DDR3, up to 1 GB                                                                                |

Shared socket no mean automatic compatibility. Boards dey often need BIOS update before newer chip wey dey di same socket go fit post.

Cooler clearance, VRM quality, and power limits matter just like di socket name.

Read di memory list on di board. Di CPU fit list more standards pass wetin one motherboard go accept.

CPU wey no get integrated graphics no need discrete graphics card every time. Some server motherboards dey provide separate management graphics controller. Check di motherboard and CPU documentation.
