EVGA X299 Micro ATX 2 (121-SX-E296)
This is optional for a single card solution, but is recommended for SLI, CFX,
and dual-processor video cards.
9. Intel
SATA 6Gbit/s Ports
®
The Intel
X299 PCH has a 6-port SATA 3/6 Gbit/s controller (See Page 44
®
for specifics on the connectors). This controller is backwards compatible with
SATA and SATA II devices, and supports SSDs, HDDs and various types of
optical devices (CDROM, DVDROM, BD-ROM, etc). The controller also
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 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 and be bolted into place and powered by the connector, rather than
by 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.
11. PCIe Slot x16/x8*
PCIe x16/x8 slots are primarily used 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.
Skylake-X Socket LGA2066 processors have 44 or 28 PCIe lanes available for
routing.
12. PCIe Slot x4*
PCIe x4 slot PE5 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.
This slot supports Intel
used in this slot, but will require a PCIe to M.2 adapter (not included).
13. Power Button
This is an onboard power button, and may be used in place of, or in
conjunction with, a front panel power button wired to the board.
