7.10.2.9 DDR2 Signal Termination
No terminations of any kind are required in order to meet signal integrity and overshoot requirements.
Serial terminators are permitted, if desired, to reduce EMI risk; however, serial terminations are the only
type permitted. Table 7-40 shows the specifications for the series terminators.

(1) Only series termination is permitted, parallel or SST specifically disallowed.
(2) Terminator values larger than typical only recommended to address EMI issues.
(3) Termination value should be uniform across net class.
(4) When no termination is used on data lines (0 Ωs), the DDR2 devices must be programmed to operate in 60% strength mode.
