Description
RDIMM 1 Y Y Y 1N SR or DR
All RDIMMs run at the fastest common
frequency of processor IMCs and installed
memory: 800MHz, 1066MHz, or 133MHz
RDIMM 1 Y Y N 1N QR only
All RDIMMs run at 800MHz or 1066MHz
when Quad-Rank RDIMM is installed in any
channel.
RDIMM 2 Y Y N 1N
SR, DR, or mixing
of SR and DR
All RDIMMs run at 800MHz or 1066MHz
when two RDIMMs (Single-Rank or Dual-
Rank) are installed in the same channel.
RDIMM 2 Y N N 1N
QR only, or mixing
of SR and QR, or
mixing of DR and
QR
All RDIMMs run at 800MHz when two
RDIMMs (either or both are Quad-Rank
RDIMMs) are installed in the same
channel.
UDIMM
w/ or w/o
1 Y Y Y 1N SR or DR
All UDIMMs run at the fastest common
frequency of processor IMCs and installed
