First Looks: GIGABYTE G1-Killer Assassin (Intel X58 Express) Motherboard

The two heatsinks cooling the processor core's voltage regulation module (VRM) are modelled after the shape of a pistol. As we can see, cooling is definitely more than adequate. Perhaps it is also worth mentioning that GIGABYTE has used a LOTES-made LGA 1366 socket.

The Freescale PowerQUICC II Pro MPC8308 is the processor behind the Bigfoot Networks Killer E2100 network solution found on the Assassin. It operates at 400MHz and two Samsung DDR2 SDRAM provides 128MB of memory primarily for buffering traffic streams of different priorities.

Note: The photo has been intentionally blurred as requested by GIGABYTE. For retail motherboards, a 'Killer E2100' logo will be affixed to the chip.


Only available on the Assassin and Sniper, is a Creative CA20K2 PCI Express X-Fi digital audio processor onboard. This is the same chip you would find in the current Creative Sound Blaster X-Fi sound card line.

The digital-to-analog converter (DAC) is a Cirrus Logic CS4382, supporting up to 24-bit 192KHz 8-channel conversion.

The high-gain high current NJM4556A dual op-amp by New Japan Radio Co. Ltd. is a tried and tested part, and is used to drive the front channels. The rest of the channels use ST Microelectronics' MC4558 dual op-amps.

Two different types of Nichicon audio-grade aluminium electrolytic capacitors are used for the Assassin's audio portion: gold-colored MW series and green-colored MUSE ES.


A 2-port NEC / Renesas µPD720200A  USB 3.0 host controller sits just above the first PCI Express x16 slot on the right; there are two VIA VL810 connected to it.


The rear I/O on the Assassin provides:

  • legacy PS/2 ports for both keyboard and mouse, 
  • coaxial output,
  • four USB 2.0 ports,
  • four USB 3.0 ports through a VIA VL810 to the NEC / Renesas µPD720200A,
  • a Gigabit Ethernet port,
  • optical output, and
  • standard analog audio connectors.

* A Marvell 88E1118R GbE physical layer transceiver (PHY) provides the link between the Gigabit Ethernet port and the Killer E2100.
