Hi
best regard

Hello,
"Using resistors with recommended tolerances ensures the ± 2% DDR_VREF tolerance
(per the DDR3 specification) is maintained when two DDR3 ICs plus the i.MX 6ULL are
drawing current on the resistor divider".
You may look at the following general considerations:

In particular: Figure 4. This simple resistor-divider analogy represents a voltage reference
unloaded (A) and loaded (B).
