Note 1 The maximum requirements for peak amplitude were reduced from 0.9V to 0.5V. Register vendor datasheet will specifiy the
maximum over/undershoot induced in specific RDIMM applications. DRAM vendor datasheet will also specify the maximum oversh-
oot/undershoot that their DRAM can tolerate. This will allow the RDIMM supplier to understand whether the DRAM can tolerate the
overshoot that the register will induce in the specific RDIMM application.
