BIOS Settings

The lack of any overclocked bus speeds, and the presence of SDRAM SPD Auto Configuration options in the AMI WinBIOS of the Supermicro motherboard make Recommended BIOS Settings obsolete for this motherboard.

The Test

In recent times, choosing a motherboard cannot be completely determined by a Winstone score. Now, many boards come within one Winstone point of each other and therefore the need to benchmark boards against each other falls. Therefore you shouldn't base your decision entirely on the benchmarks you see here, but also on the technical features and advantages of this particular board, seeing as that will probably make the greatest difference in your overall experience.

How I Tested

  • Each benchmark was run a minimum of 2 times and a maximum of 5 times, if the motherboard failed to complete a single test within the 5 allocated test runs the OS/Software was re-installed on a freshly formatted Hard Drive and the BIOS settings were adjusted to prevent the test from failing again.  All such encounters were noted at the exact time of their occurrence.

  • Business Winstone 98 was run at each individually tested clock speed, if reliable scores were achieved with the first two test runs of the suite an average of the two was taken and recorded as the final score at that clock speed.  If the test system displayed erratic behavior while the tests were running or the results were incredibly low/high the tests were re-run up to 5 times and an average of all the test runs was taken and recorded at the final score at that clock speed

  • After each motherboard was tested a complete format of the test hard drive was initiated and the OS/benchmarking software was re-installed afterwards a defragment was initiated using Windows 95's Disk Defragmentation Utility

  • Tests using AGP Video cards were run under Winstone 97 and Winstone 98

  • No foreign drivers were present in the test system other than those required for the system to function to the best of its ability

  • All foreign installation files were moved to a separate partition during the test as to prevent them from effecting the test results

  • All tests were conducted at 800 x 600 x 256 colors

The Final Decision

For a multi-processor High End Server/Workstation motherboard the P6DBS cannot be beat, Supermicro has been making dual processor motherboards for longer than some manufacturers have been in the spotlight, and they know how to make a motherboard.  Overclocking in a do-or-die server situation is usually frowned upon, making the lack of a 112MHz bus speed setting less and less evident with this motherboard.  The pricetag on the board may keep quite a few potential buyers away, but once again, you get what you pay for in this industry.
