EVGA Z370 MICRO (121-KS-E375)
- 16 -
supports NCQ, TRIM, hot swap capability (provided the proper HDD/SSD
bays/racks are installed), and RAID levels 0/1/5/10.
10. M.2 Socket 3 Key-M 80mm
M.2 is an SSD form factor 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.
This connector can utilize only PCIe/NVMe-based M.2 SSDs or Intel
®
Optane
NVMe devices.
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 2
(PE2). Lanes automatically switch from x16/x0 to x8/x8 when the
motherboard detects a card in slot PE2.
12. PCIe Slot x8
PCIe x8 slots are primarily used for video cards, and share lanes from adjacent
x16 slots, when populated. These full-length slots will provide 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 1 (PE1). This slot is primarily recommended for
secondary video cards, such as the 2
nd
card in a SLI configuration, or a PhysX
card.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 19.
13. PCIe Slot x4
PCIe x4 slot PE3 uses up to 4 Gen 3 lanes from the PCH. This slot is typically
used for sound cards, WiFi, USB, LAN or other peripheral cards.
Using this slot will have *NO EFFECT* on the bandwidth or throughput of
the x16 slots used for SLI because this slot uses only PCH bandwidth.
