NVIDIA SLI-AA

NVIDIA introduced special SLI-AA Modes beginning with driver version 77.7x. By running Coolbits, selecting "Advanced Settings" under "View" in the "Performance & Quality Settings" area, and selecting "SLI-Antialiasing" under the "SLI Rendering Mode", you have new options to run games at 16xAA or 8xAA independent of application control. There are many potential advantages to SLI-AA mode. You can find more information on how this feature works and the potential benefits at NVIDIA Announces 16x AA For SLI.

Since some have reported dramatic increases of up to double the speed using SLI-AA with the Dual x16 board, we ran benchmarks in SLI-AA modes using the same Far Cry game using our Regulator benchmark. As in our other testing the CPU, memory and drivers were the same for both boards. We even moved the hard drive between the two test setups to make sure everything except the motherboard was exactly the same. Since we had some problems with stability of the release 81.85 drivers in SLI-AA mode, we used the more recent 81.87 drivers which are also available in the Beta section at nVidia's wesite.

nVidia SLI-AA Mode - 1600x1200 - FPS



As you clearly see from the test results we did not find ANY performance improvement in either SLI-AA mode on the Dual x16 board compared to the Dual x8. In fact, the DFI Dual x8 was slightly faster than the Asus Dual x16 in theses tests. The results, however, were well within error tolerance and are equivalent - no difference. Perhaps more memory or lower resolutions would yield different results, but in the past we have consisitently found higher resolutions to benefit most from SLI and antialiasing.

    I've been waiting for this board for over 2 weeks now and it still isn't available anywhere in europe.

    So i would love to get this board shipped from USA to The Netherlands (where i live).

    Does anyone know a good USA Computershop that has these boards in stock and accept Mastercard payments!?!?!?!?

    I don't care about the shippingcosts, as long as they can ship FAST :)

    If we're supposed to upgrade to new drivers to take advantage of improvements, Nvidia needs to seriously work on their driver upgrades, especially the platform drivers. To avoid problems, we have to use a third-party driver cleaner. The only users that seem to get NAM working are those that do a fresh install of Windows. Any attempt to upgrade drivers and enable NAM results in BSOD.

    This has been brought up before, with AT staff saying that it would be looked into if we could point to information about the problems. Users posted links to forum threads of users experiencing the problem, and there have been more threads since Nvidia released new drivers, but still we wait to hear any follow-up from AT or Nvidia.

    seriously.

    I'm running 6.66 forceware drivers right now. I'm thinking about formatting so I can get that 17% increase from 6.82. However, I have an ATI card. Is the performance increase due to the forceware drivers, or the graphics drivers? Or is it from the combination of the two?

    Either way, we need a way to upgrade the drivers safely without all the crap of reformatting.

    The 6.82 platform drivers are officially just for Dual X16. The latest platform driver for the regular nForce4/SLI chipset is 6.70. The video drivers that boost performance are the 8x.xx series. The released version on the nVidia website is 81.85 which can be used to improve performance of all recent nVidia video cards. There is also a Beta 81.87 floating around.

    Aren't the 6.82's for the x16 motherboards only?

    Thanks for the review.

    This is a really nice looking motherboard. The passive cooling is very much welcomed, and the 8-phase power is interesting, and if it saves power that's good.

    I hope that nVidia sort out their audio woes soon however. I look at my >30 month old nForce2 system and that's got way better integrated audio. On a $200 motherboard, is the dolby fee really an issue?

    I could only see one SATA connector for the SI SATA.

    3 PCI slots is nice for backwards compatibility, but in the long run things will emerge for PCIe, and the x4 slot is great and all (esp. for a decent SATA RAID card, then again, there's 6 fricking SATA ports already on the motherboard), but would it have done much harm to have another PCIe slot in place of one of the PCI slots? As long as the middle PCI slot was left for a decent audio card anyway.

    How are the Firewire, SATA and Gigabit controllers connected? Via PCI or PCIe?

    How does the power draw at the socket compare with other solutions?

    I've read a bunch of complaints on the recent Asus boards that the chipset fans are quite loud and have been breaking down. Is that a potential problem on this board?

    Perfomance to cost wise, is their any reason to choose the Asus over the DFI board?
  • Zebo - Friday, November 4, 2005 - link

    BTW all you got to do is replace chipset fan with a passive chipset heat sink on any asus' budget boards... like $5.. I do anyway on any board ( I cut stock heat sinks in quarters on my table saw). Can't stand those 6000+ rpm whinners.. that particular high pitched tone is really ear pierceing to me.
  • Capt Caveman - Friday, November 4, 2005 - link

    Umm, this motherboard doesn't have any chipset fans but uses passive heatpipes for cooling. Did you read the review or look at the pics?
  • cyberfrog4646 - Friday, November 4, 2005 - link

    HAHAHAH, whoops, i just looked at the benchmarks and conclusion. I thought the the pipe was for the cpu based on the opening picture. Ah well, thanks for the info.
