Primary and Secondary Connector Rows
The following subsystems can be found on the primary and secondary connector rows.
5.1.1
PCI Express™
The conga-TC570 offers up to eight PCIe lanes—up to six lanes on the A–B connector and up to two lanes on the C–D connector. The conga-
TC570 supports the following:
•
up to 8 GTps (Gen 3) speed
•
a 6x1 link default configuration (with SATA ports enabled)
1,2,3 ,
•
a 1 x4 + 2 x1 link or 2 x2 + 2 x1 link or 1 x2 + 4 x1 link via a special/customized BIOS firmware
•
lane polarity inversion
Note
1.
PCIe lane 5 and PCIe lane 6 are multiplexed with SATA port 1 and SATA port 0 respectively.
2.
PCIe lane 7 is multiplexed with USB 3.2 Gen 2x1, port 3.
3.
The number of PCIe lanes increases if the multiplexed ports are not enabled.
5.1.2
PCI Express Graphics (PEG)
The conga-TC570 supports one PCIe x4 Gen 4 (PEG) port on the C
–
D connector. The port supports both graphics and storage devices and
can be operated as x1 or x4 link.
Note
The PEG lanes can not be linked together with the PCI Express lanes in section 5.1.1 “PCI Express™”.
