Introducing the Motherboard
Introduction
Thank  you  for  choosing  the A780GM-A  Ultra  motherboard. This  motherboard  is  a
high  performance,  enhanced  function  motherboard  that  supports  socket  for AMD
PhenomTM processor  (socket  AM2+)/AthlonTM  64  X2  Dual-Core/AthlonTM  64/
SempronTM  processors  for  high-end  business  or  personal  desktop  markets.
The  motherboard  incorporates  the  AMD  780G  Northbridge  (NB)  and  SB750
Southbridge  (SB)  chipsets.  The  Northbridge  supports  the  HyperTransportTM 3.0  in-
terface.  The  memory  controller  supports  DDR2  memory  DIMM  frequencies  of
1066*1  (AM2+)/800/667/533/400.  It  supports  four  DDR2  slots  with  maximum
memory size of 32 GB*2. One PCI Express x16 slot, intended for Graphics Interface,
are  fully  compliant  to  the  PCI  Express  Genaration  2.0  (version  2.0).
The  SB750  Southbridge  supports  three  PCI  slots  which  are  PCI  2.3  compliant.  In
addition, two PCI Express x1 slots are supported, fully compliant to the PCI Express
Generation  2.0  (version  2.0).  It  integrates  USB  2.0  interface,  supporting  up  to
twelve functional ports (six USB ports and three USB 2.0 headers support additional
six USB ports).  One onboard IDE connector supports two IDE devices in Ultra ATA
133/100/66/33  modes.  The  Southbridge  integrates  a  Serial ATA  host  controller,
supporting  six  SATA  ports  with  maximum  transfer  rate  up  to  3.0  Gb/s  each.
There is an advanced full set of I/O ports in the rear panel, including PS/2 mouse and
keyboard  connectors,  one  VGA  port,  one  HDMI  port,  six  USB  ports,  one  ESATA
port, one optical SPDIFO port, one LAN port  and audio jacks for microphone, line-
in  and  6/8-channel  High  Definition Audio  output.
*
1.  Whether  1066  MHz  memory  speed  is  supported  depends  on  the  CPU
being  used.
2. Currently, the memory maximum size we have tested is 8 GB (2 GB per
dimm).
