Test Setup

The Intel 975X chipset fully supports the 820, 830, and 840 dual core Pentium D processors in both stock and overclocked conditions. This chipset also supports the upcoming Presler and Cedar Mill processor range. Dual core really makes a difference in certain multi-tasking scenarios, as was demonstrated in the dual core performance preview. If you are interested in how the various chipsets perform in a real world multitasking setup, please take another look at that review.

NVIDIA SLI Performance

The 975X chipset is able to support NVIDIA SLI technology with a specially configured and non-certified 78.01 driver along with proper bios support. However, NVIDIA has not sanctioned or licensed their SLI technology on the Intel platform.

NVIDIA SLI Performance

We have included ATI CrossFire results in these tests to indicate the ability of the X850 CrossFire Edition to operate on an Intel 975X platform. The X850 CrossFire solution is not competitive with the current NVIDIA 7800GTX SLI offerings. We did not witness any issues with the ATI CrossFire setup while testing the Intel 975X boards. We look forward to the X1800 CrossFire Edition cards as performance should be on par with the current Nvidia 7800GTX 256mb offerings.

Although the performance does not match the newer 81.xx series of drivers, the 975X boards are still competitive with the nForce4 Intel Edition SLI setup considering the beta condition of the non-certified drivers used. We noticed some graphic anomalies with the Asus P5WDG2-WS in the benchmarks that explains the lower scores compared to the Gigabyte board.

The ability of the 975X based boards to run both ATI CrossFire and NVIDIA SLI setups is definitely a marketing plus, but until Intel licenses and NVIDIA fully certifies and sanctions SLI on the Intel platform, we can only wonder what the impact would be in the market.

Overclocking Performance

The overclocking performance graphs have been added to the standard benchmark test suite and should allow for a better comparison on the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of this board, please refer to the Overclocking and Memory Stress Test section in the Basic Features section.

Overclocking

Overclocking

The front side bus overclocking results were impressive for the Intel 975X boards and exceeded those of the Asus P5N32-SLI with the Smithfield based processor. We will see how well the nForce4 based P5N32-SLI does with the Presler and Cedar Mill processors in our next article.

    Can you tell us what power supply was used on this Asus multi-layered board ? What kind of power muscle did get used. ? [ ]

    Thanks.Didn't see it right off in table of 'Setup.
  • Gary Key - Wednesday, December 7, 2005 - link

    We used the OCZ Power Stream 520. It is our standard power supply for testing. I have listed in the overclocking setup but not in the regular test setup. I will add that line in the next article.

    Thank you.

    Cool quote from the man often referred to as the first US psychologist. The psychology building at Harvard, where he was a professor, is also named after him. And I'm pretty sure he got that honor without giving them a ton of money.

    just wondering how the board would compare using the Via Envy HT-S sound chip...
  • Gary Key - Tuesday, December 6, 2005 - link

    Would a Chaintech AV710 satisfy your question? ;->

    I have some horrible 945G board (don't ask, I use a 7800GT lol), and I can't even run PC2-6400 over 667, nor will the computer not crash if I put the bus over 205. :(

    So when are the 975x boards supposed to come out? I see some of the Intel boxes listed now in froogle (not usually in stock though), but not from Gigabyte, Asus, or anyone else yet. :) I'd be happy if it is before the 21st (my birthday). This Asus board looks like it'll be exceedingly expensive, though.

    Boards featuring the 975X chipset should hit retail stores sometime this week. We'll see...
  • Gary Key - Tuesday, December 6, 2005 - link

    The 975x boards should be shipping in volume by the end of the year. We expect to see a small sampling of boards in the retail channel as early as next week but as always that could change.

    Right... I am gonna overclock my workstation system by 30%....

    I know the overclock testing was a bit much for a "workstation" board but it does give an indication to the quality of the components used on the board.
