EVGA X299 Micro (131-SX-E295)
- 17 -
Th
is connector is designed only to work with an EPS or CPU cable. System
builders may make the mistake of plugging in a PCI-E 8-pin or 6+2-pin
connector, which will prevent the board from POSTing and possibly damage
the board; although the cables appear similar, they are wired differently and
attaching a PCI-E cable to an EPS connector may cause damage to the
motherboard.
Alternatively, if no power cable is connected or detected, the system will not
POST and will hang at POST code “C.”
9. Intel SATA 3/6G Ports
The Intel X299 PCH has a 6-port SATA 3/6G controller (See Page 47 for
specifics on the connectors). This controller is backwards-compatible with
SATA and SATA 2 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. U.2 Port (SFF-8639)
U.2, originally known as SFF-8639, is a high bandwidth connection specifically
engineered for next generation SSD’s. U.2 brings PCI-E x4 (Gen3) NVMe
performance to a 2.5” SSD form factor and provides a solution to potential
heating problems that may be present in some M.2 solutions.
11. M.2 Socket 3 Key-M 80mm
M.2 is a SSD standard, which uses up to four PCI-E 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 either a PCI-E/NVMe based M.2 SSD, SATA M.2,
or Intel Optane devices.
12. PCI-E Slot x16/x8*
PCI-E 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.
