System Does Not Post, And Post Code Indicator Reads "55" Or "B7; System Does Not Post, And Post Code Indicator Reads "D7 - EVGA X299 DARK Owner's Manual

EVGA X299 DARK (151-SX-E299)
System does not POST, and POST code
indicator reads "55" or "b7"
A POST code error reading "55" or "b7" indicates a memory issue. Verify that memory
is installed, and that is it properly seated. Make sure that the memory is on the official
support list at www.evga.com/support/motherboard and click on "EVGA X299
DARK." If the memory is not on the list, it may still work because EVGA is unable to
test every memory kit released. However, this motherboard will not support modules
over 16GB or ECC/Registered RAM.
If your memory should work on this motherboard, the next step is to bring it down to
one stick of memory in "DIMM slot 3" and retest. If this is your first boot with the
motherboard and the board will not POST, your next step is to press the "Reset CMOS"
button. The system will power on when the Reset CMOS button is pressed, which is
normal. This should allow the system to boot up. When you see the EVGA X299
DARK screen, press "Del" to enter BIOS, set the XMP (instructions are covered in first
boot section on Page 57), press F10 to save and exit, which will reboot the system. If
the system reboots successfully, you can power down and install the rest of the memory
to retest.
System does not POST, and POST code
indicator reads "d7"
If the motherboard cannot detect a Keyboard, the system will fail to POST with a "d7"
POST code. When this happens, some video card / monitor setups will display a
message on screen about a Keyboard error, while others will just remain blank. If this
happens, power down the system and reseat the USB connector. Make sure the
Keyboard is NOT in the USB 3.1 Type-A connector, as this port requires drivers to
initialize and fully function. However, this error can sometimes happen with older
wireless keyboards, as well. If this is the case, we recommended that you plug in a
regular USB keyboard, reboot, enter BIOS, and go to Advanced – USB Configuration.
Make sure "Legacy USB Support" is set to "enabled," then press F10 to save and exit.
Your keyboard should now work, and the board should POST past "d7."
