AMD 880G Mobo Roundup - New Mainstream Integrated Graphics

By Vincent Chang - 27 May 2010

BIOS Settings & Test Setup

BIOS Settings

For a supposedly mainstream chipset, with numerous microATX designs, there are plenty of BIOS tweaks for the average user. We see this as the inevitable effect of motherboard vendors migrating their usual enthusiast capable BIOS designs to even the more mainstream products, disabling only features that don't apply. As a result, the ASUS and Biostar both gets some form of an automated overclocking tool, while all three boards have more than sufficient BIOS options. We have listed some of the more prominent ones below:

Test Setup

The prices for AMD processors are very affordable and with 6-core processors debuting recently, we felt that most users will have no qualms (and the budget) to dump into a quad-core processor, so for this roundup, we have outfitted the AMD 880G boards with our Phenom II X4 955 (3.2GHz) processor. Besides the three AMD 880G boards, we have included a reference AMD 785G board in our testing to ensure that there's a baseline to compare with. In most cases, there's little to separate the AMD 880G with the 785G.

  • AMD Phenom II X4 955 (3.2GHz)
  • 2 x 1GB Kingston HyperX DDR3-1333 @7-7-7-20
  • Seagate Barracuda 7200.10 SATA HDD (single NTFS partition of 200GB)
  • Radeon HD 4250 (dependent on board's default clocks, 256MB frame buffer, Catalyst driver version 8.71)
  • Windows 7 Ultimate

The following benchmarks were used:

  • BAPCo SYSmark 2007 Preview (ver 1.05)
  • Futuremark PCMark Vantage (ver
  • Futuremark 3DMark06 (ver 110)
  • SPECviewperf 9.0
  • Quake 4 (ver 1.3)
  • Unreal Tournament 3 (ver 1.1)
  • Black Snake Moan and Superman Returns Blu-ray discs for HD playback testing
