EVGA Z370 FTW (134-KS-E377)
supports NCQ, TRIM, hot swap capability (provided the proper HDD/SSD
bays/racks are installed), and RAID levels 0/1/5/10.
9. M.2 Socket 3 Key-M 80mm
M.2 is an SSD standard, which uses up to four PCIe lanes and utilizes Gen3
speeds. Most popularly paired with NVMe SSDs, this standard offers
substantially faster transfer speeds and seek time than SATA interface
standards. All M.2 devices are designed to connect via a card-bus style
connector, secured by bolting into place, and powered by the connector – rather
than a dedicated data cable and power cable.
This socket will support Key-M devices of 80mm, 60mm, and 42mm length.
Conflict: Each Key-M shares lanes with SATA ports 0/1 or 4/5, respectively.
As a result, these devices are mutually exclusive and must be enabled/disabled
in the BIOS.
10. M.2 Socket 1 Key-E 32mm
M.2 Key-E sockets are generally used for WiFi and Bluetooth cards. Key-E and
Key-M connectors are different, meaning that devices are not interchangeable
between sockets.
Conflict: Key-E shares one PCIe lane with PCIe slot 3 (PE3). As a result, these
devices are mutually exclusive and must be enabled/disabled in the BIOS.
11. PCIe Slot x16/x8
PCIe x16/x8 slots are primarily for video cards. These full-length slots will
provide 8 or 16 lanes of bandwidth to a full-size card, and are backwards-
compatible with x8, x4, and x1-length cards.
Coffee Lake-S Socket 1151 processors have 16 PCIe lanes available for routing.
The 16 PCIe lanes are pulled from the CPU and shared with the x16 PCIe slot 4
(PE4). Lanes automatically switch from x16/x0 to x8/x8 when the
motherboard detects a card in slot PE4.
12. PCIe Slot x8
PCIe x16/x8 slots are primarily for video cards. These full-length slots will
provide up to 8 lanes of bandwidth to a full-size card, and are backwards
compatible with x8, x4, and x1 length cards.
This slot is limited to a maximum of 8 lanes as it shares bandwidth with the
primary PCIe x16 slot 2 (PE2). This slot is primarily recommended for
secondary video cards, such as the 2
card.
