Therefore, the northbound data connection will exhibit the same peak theoretical
throughput as a single DDR2 SDRAM channel. For example, when using DDR2-533
components, the peak theoretical bandwidth of the northbound data connection is
4.267 GB/s.
Write data is transferred on the southbound command and data connection, via
Command + Wdata frames; 72 bits of data are transferred per frame. Two Command +
Wdata frames match the 18-byte data transfer of an ECC DDR2 SDRAM in a single DDR2
SDRAM command clock.
A DDR2 SDRAM burst of eight transfers from a single channel, or a burst of four from
two lock-step channels, provides a total of 72 bytes of data (64 bytes plus 8 bytes ECC).
When the FBDIMM frame rate matches the DDR2 SDRAM command clock, the south-
bound command and data connection will exhibit one-half the peak theoretical
throughput of a single DDR2 SDRAM channel. For example, when using DDR2-533
SDRAMs, the peak theoretical bandwidth of the southbound command and data
connection is 2.133 GB/s.
The total peak theoretical throughput for a single FBDIMM channel is defined as the
sum of the peak theoretical throughput of the northbound data connection and the
southbound command and data connection. When the FBDIMM frame rate matches
the DDR2 SDRAM command clock, it equals 1.5X the peak theoretical throughput of a
single DDR2 SDRAM channel. For example, when using DDR2-533 SDRAM devices, the
peak theoretical throughput of a DDR2-533 channel would be 4.267 GB/s, while the peak
theoretical throughput of an FBDIMM-533 channel would be 6.4 GB/s.
