Memory
Q35 motherboards have four 240-pin DIMM sockets to support up to 8GB of 64-bit,
unbuffered non-ECC DDR2 800/667MHz dual-channel memory modules. Each socket can
accept either single channel mode or dual-channel interleaved mode.
In general, compatible memory modules must:
ƒ
Support 512Mb and 1Gb memory technology in x8 and x16 organization.
ƒ
Supports maximum memory bandwidth of 6.4 GB/s in single-channel or dualchannel
asymmetric mode, or 12.8 GB/s in dual-channel symmetric mode assuming DDR2 800
MHz.
ƒ
Using 512 Mb device technologies, the smallest memory capacity possible is 256 MB,
assuming Single Channel Mode with a single x16 single sided un-buffered non-ECC DIMM
memory configuration.
ƒ
Using 1 Gb device technologies, the largest memory capacity possible is 8 GB, assuming
Dual Channel Mode with four x8 double sided un-buffered non-ECC DIMM memory
configuration.
The BIOS automatically configures the motherboard for the correct size, speed, and type. For a
list of qualified memory modules, refer to the
Procelerant Endura Q35 Qualified Memory List
on the RadiSys Web site.
