NOTES:
1. Refer to JEDEC PC2-4200/5300/6400 DDR2 FULLY BUFFERED DIMM DESIGN SPECIFICATIONS, rev 2.0.
2. The resistor R must be 0Ω and the inductor L needs to be replaced with a 0Ω resistor. The resistor R
3. It is not recommended to use a serpentine copper trace in place of the resistor R. This resistor value needs to be AMB manufacturer defined and not set to a single fixed value.

ADVANCED MEMORY BUFFER FOR FULLY BUFFERED DIMM
Some raw cards have implemented the resistor with a serpentine copper trace on the DIMM PCB, while others use a discrete resistor. The limitation of using the copper trace
has been discussed in JEDEC, highlighting that the resistor implemented as a serpentine copper trace is not a generic solution. The raw card artwork now allows the option of
bypassing any serpentine trace with a 0Ω resistor to V
