3. PCIe x16 Slot

This is PCI Express 1.0a (not 2.0 or 3.0). It works with modern low-power GPUs (e.g., GT 710, GT 1030) but may bottleneck faster cards.

Critical Warning from the manual: This board does not support SATA II (3.0 Gbps) or SATA III drives natively. If you install a modern SATA SSD, it will work but be throttled to SATA I speeds (150 MB/s). Also, the board lacks a floppy connector on many revisions. acer socket lga775 pcie motherboard 915m08g8ks manual
