SATA ports
: J20 (Hard Disk), J23 (DVD/CD), J21, J22
PCI slots
U3 – PCI slots running at 66 Mhz
U28 – PCI slots running at 33 Mhz
U32 – PCI slots running at 33 Mhz
For better performance we suggest to use the U3 slot for plugging a
graphics card.
RAM slots
Both memory slots are the same. In case only one memory module is
used, it can be installed in either one.
