Introducing the Motherboard
Introduction
Thank  you  for  choosing  the  945GZT-M  motherboard. This  motherboard  is  a  high  perfor-
mance,  enhanced  function  motherboard  designed  to  support  the  LGA775  socket  Intel
CoreTM2  Duo/Pentium  D/Pentium  4/Celeron  D  processors  for  high-end  business  or  personal
desktop  markets.
The  motherboard  incorporates  the  945GZ  Northbridge  (NB)  and  ICH7  Southbridge  (SB)
chipsets. The Northbridge supports a Front Side Bus (FSB) frequency of 800/533 MHz using
a scalable FSB Vcc_CPU. The memory controller supports DDR2 memory DIMM frequen-
cies  of  533/400.  It  supports  two  DDR2  Sockets  with  up  to  maximum  memory  of  2  GB.
DDR2 Maximum memory bandwidth of 8.5 Gb/s in dual-channel interleaved mode assuming
DDR2  533  MHz.  High  resolution  graphics  via  one  PCI  Express  slot,  intended  for  Graphics
Interface,  is  fully  compliant  to  the  PCI  Express  Base  Specification  revision  1.0a.
The  ICH7  Southbridge  supports  two  PCI  slots  which  are  PCI  2.3  compliant.  It  implements
an  EHCI  compliant  interface  that  provides  480  Mb/s  bandwidth  for  eight  USB  2.0  ports.
One  onboard  IDE  connector  supports  2  IDE  devices  in  Ultra ATA  100/66/33  mode.  The
Southbridge  integrates  a  Serial ATA  host  controller,  supporting  four  SATA  ports  with  maxi-
mum  transfer  rate  up  to  3.0  Gb/s  each.
The motherboard is equipped with advanced full set of I/O ports in the rear panel, including
PS/2  mouse  and  keyboard  connectors,  COM1,  one  optional  LPT  port,  one  VGA  port,  four
USB  ports,  one  optional  LAN  port  and  audio  jacks  for  microphone,  line-in  and  line-out.

GB/s)each  direction.
Supports 256-Mb, 512-Mb and 1-Gb DDR2 technologies for
x8 and x16 devices
Supports high quality 3D setup, Render Engine and high-
quality texture engine
Enhanced DMA Controller, interrupt controller, and timer func-
tions
Compliant with PCI Express Base Specification, Revision
1.0a
