Asus A8N32-SLI Deluxe: NVIDIA Dual x16 for the Athlon 64

Final Words
It's a shame that the first task in reviewing the truly excellent Asus A8N32-SLI Deluxe is to set the record straight. Despite what you may have seen at other web sites, we can tell you conclusively that the Asus A8N32-SLI is not 40% to 50% faster in some games than the current Dual x8 designs. Those who concluded this overlooked the impact of the new 81.85 NVIDIA drivers and 6.82 platform drivers on the board's performance. These new drivers are definitely faster - so much so that current NVIDIA owners should definitely upgrade their video drivers.
We truly expected no increase in performance at all with the new Asus Dual x16 once the playing field was leveled. What we actually found, however, was that the A8N32-SLI Deluxe is slightly faster in both single video and SLI running our current test suite games like Doom 3, Far Cry, and Aquamark 3. The A8N32-SLI is faster, but at levels that are generally within the margin of error.
There is more to the story though. While we can't fully explain why it is faster, we did find the Asus A8N32-SLI Deluxe to be as much as 8% faster on the newest games that we tested in SLI mode, and up to a whopping 17% faster in single video mode with single/dual 7800GTX video cards. These are significant increases in performance that can't be ignored. We don't know why this is the case, and we will be testing this further as more Dual x16 boards appear in the marketplace. Perhaps it is the Asus design, perhaps it is the MCP51, and perhaps it could be anything.
Please do not let the debunking of the 40% to 50% claims that others have made for this board's performance sway your opinion of the Asus A8N32-SLI. This is one fast Socket 939 motherboard worthy of a place in any enthusiast's Athlon 64 system. The 8-phase works very well to keep the board stable and cool, the heat pipes and no fans really work, and Asus even provides optional cooling fans for those who will use water cooling with this board. If you want to build a super performance, silent PC or a water-cooled or phase-change cooled super overclocker, the A8N32-SLI will serve you well. We couldn't say anything close to this about recent Asus boards, but Asus obviously designed this board to turn some heads in the Athlon 64 market.
The Asus A8N32-SLI is also a monster overclocker, reaching the highest overclock ever with our stock CPU and to 310FSB with a reduced multiplier. If you compare this performance to our other reviews of recent Asus Socket 939 boards, you may wonder if they were produced by the same company. Asus has become serious about Athlon 64, and it shows in the design, execution and performance of the A8N32-SLI Deluxe.
The A8N32-SLI is blessed with a unique and very effective design that truly works. The 8-phase design behaves gracefully under extreme loads and remains much cooler than other 3- or 4-phase designs. This yields excellent stability and headroom that we have not seen before on an Asus Socket 939 design. Asus claims that the board is up to 15°C (36°F) cooler than conventional solutions, and we saw nothing in our testing to make us doubt this claim. The board remained cool and stable under the most difficult test conditions.
In the end, we still have some reservations as to whether Dual x16 makes any difference at all in video performance. It certainly appears to improve performance greatly in the latest, greatest, and most demanding games, but we will need to dismiss other potential explanations before we become a true believer. We do not, however, have reservations about the A8N32-SLI Deluxe. This board is a definite keeper.

________________________________________________________________________________________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.bob661 - Friday, November 4, 2005 - link
Aren't the 6.82's for the x16 motherboards only?psychobriggsy - Friday, November 4, 2005 - link
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?

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.
