SY-P4RS350 / P4RC350 Quick Start Guide
Step 2.
Configure Memory
SY-P4RS350
supports two Dual Channels to your memory. Note that you can use
(non-ECC) DDR memory for Dual Channel to work. Also note that for Dual channel to
work 2 or 4 modules of equal size and specifications have to be installed. ECC and
registered memory are not supported.
The largest memory capacity possible is 4GB. On this motherboard, DRAM speed
can be set independent from the CPU front side bus speed. Note that when installing
4GB of memory, your total memory will be less than 4GB. The reason for this is that the
BIOS, PCI and AGP cards claim part for your CPUs address space.
