SM_RCOMP[2:0]
System Memory Impedance Compensation:  I/O
A
SM_VREF
DDR3/DDR3L/DDR3L-RS Reference Voltage: This signal is 
used as a reference voltage to the DDR3/DDR3L/DDR3L-RS 
controller.

SA_DIMM_VREFDQ
SB_DIMM_VREFDQ
Memory Channel A/B DIMM DQ Voltage Reference: These 
output pins are connected to the DIMMs, and are programmed to 
have a reference voltage with optimized margin.
The nominal source impedance for these pins is 150 Ω.
The step size is 7.7 mV for DDR3 (with no load) and 6.99 mV for 
DDR3L/DDR3L-RS (with no load).

CFG[17:0]
Configuration Signals:
The CFG signals have a default value of '1' if not terminated on the 
board. 
• CFG[1:0]: Reserved configuration lane. A test point may be 
placed on the board for this lane.
• CFG[2]: PCI Express* Static x16 Lane Numbering Reversal.
— 1 = Normal operation
— 0 = Lane numbers reversed
• CFG[3]: Reserved
• CFG[4]: eDP enable
— 1  =  Disabled
— 0  =  Enabled
• CFG[6:5]: PCI Express* Bifurcation: 
— 00 = 1 x8, 2 x4 PCI Express*
— 01 = reserved
— 10 = 2 x8 PCI Express*
— 11 = 1 x16 PCI Express*
• CFG[17:7]: Reserved configuration lanes. A test point may be 
placed on the board for these pins.

RSVD
RSVD_TP
RSVD_NCTF
Reserved: All signals that are RSVD and RSVD_NCTF must be left 
unconnected on the board. However, Intel recommends that all 
RSVD_TP signals have via test points.
