Asus A8N32-SLI Deluxe: Board Layout
Recent top-line motherboards form Asus have been part of the Ai Life series, and the A8N32-SLI Deluxe continues that tradition.
Like the Intel version of the 32-SLI,
gaming is emphasized in all of the packaging and manuals. That makes perfect sense in this AMD version of the Dual x16 design.
Layout of the A8N32-SLI Deluxe is close to, if not exactly, the layout of the Intel version reviewed last week. This should come as no surprise, since both versions are based on similar NVIDIA chipsets. The board is dominated by interacting heatpipes in a totally fanless and silent design.
The CPU socket area is dominated by MOSFET heatsinks along two sides of the CPU. These heatsinks are cooled by the CPU fan in an air-cooled system, but this board's design invites water cooling.
With a water cooling block on the CPU, there is often no fan, so Asus provides fans that can be attached to the heatsinks for cooling with a water block - or if you just want better cooing in a heavily overclocked system.
The layout is typically Asus, which means that it is generally very well done. We were particularly pleased to see the floppy and hard drive connectors on the upper-right edge of the board where they belong. The IDE connector that falls a bit south of mid-line is an edge connector, which should not interfere with other components in the area.
Power connections are split, but both the 24-pin and 12v are on board edges, so bulky power cables don't need to be snaked over the CPU.
This AMD version uses a 4-pin 12v connector compared to the 8-pin used on the Intel version. This should be your first clue that the current AMD design is not quite as demanding of power as the Intel version.
Another example of lower power demands of the AMD design is the EZplug connector to provide more power to the video cards. On the Intel design, the board will not operate properly without connecting EZPlug. On the AMD version, the manual says that the EZPlug is only needed if you are using 2 cards "without their own auxiliary power connectors". Otherwise, EZPlug is not needed for stability.

Sata is all Sata 2 - 4 ports from the South bridge plus 2 Sata2 from the Silicon Image 3132. Everything on the board is similarly state of the art except for audio.
ATI recently raised the bar for AMD on-board sound by including hooks for High-Definition audio in their Rx480 chipset for AMD. With that in mind, AC '97 audio is now inadequate for most users - even if it supports 8 channels. There is the less-than-stellar sound quality of AC '97, combined with the higher-than-average CPU usage that robs performance from games. Unless your needs are pretty basic, we would suggest disabling the on-board audio and installing a real sound card. It is ironic that NVIDIA pioneered decent on-board sound with their nForce2 chipset, and they now have the worst audio solution available for AMD. We hope that NVIDIA will change that in the near future.

Well i have finally gotten my replacement board, and again i have a major issue with it. It seems that in some fit of wisdom, one of asus's underpaid engineers placed a heatpipe right in the way of the x4 PCIe slot. You might not have a use for them, but i certainly do. I have a PowerColor Theatre 550Pro x1 TV Tuner that is right now occupying an x16 slot. While i dont intend to do SLI, i would dearly like to have dual tuners without having to have one on pci, the other on PCIewbloon - Sunday, December 18, 2005 - link
I'm not a big gamer. But I currently drive 2 monitors and with the new system want to drive at least 3 monitors and possibly a TV.So my question is can I drive two video boards but not in SLI mode, since it is my understanding that SLI will only drive one monitor.
I understand that I could get away with a board like the DFI Ultra and have 16 lanes to one card and 4 lanes to another and that would probably meet my needs but I'd like stretch the envelope where ever possible because the future keeps coming despite my best efforts.

unless you are gaming on both cards (which probably wont) having 4 lanes is more than sufficient. The bandwidth would be comparable to AGP4 in the downstream. This solution is about as future proof as it gets. To answer your question, yes this board basically has 2 full bandwidth X16 slots, what you do with them is up to you. Buying this board soley for the extra 16 lanes is really a waste of money, unless there is some other reason you like itBibbidyBobidyBoo - Wednesday, December 7, 2005 - link
I recently purchased this motherboard and an Antec NeoHe 550W PS and the combo worked great for about 5 to 10 min and then the computer spontaneously shuts down. The issue is with the PS not the MB. The Antec TruePowerII 550W PS works just fine. I believe the incompatibility is from the amount of current supplied on the 12V and 5V lines, it may match the ATX2.2 spec however it is not completely backwards compatible with this Asus MB.Beware this issue has also been noted on other Asus MB’s.

Can someone confirm to me that no single x16 video slot version of this Asus motherboard exists? I get the impression that none does. Also, anyone know if the latest zalman CPU coolers fit? Finally, I know most here wouldn't care for the Asus automatic overclocking results but for someone like me, can you please inform me, Wesley, as to how much of a boost does the inbuilt Asus overclocking facility provide please?Many thanks

Umm, this new chipset is for SLI, thus the chipset name x16 SLI. The pci-e video slot is already x16 on every single video slot socket 939 pci-e motherboard. Up til now, SLI motherboards had to split the x16 into two x8 pci-e graphic slots. Thus, you will never see a single slot video care motherboard using this chipset.And yes, it has been confirmed by current users that the Zalman coolers fit.
Due to the fact that Asus's Overclocking Utilities lack a number of settings that are available in the bios, ie. memory settings, you'll only be able to get a small overclock before the system becomes instable. Overclocking via the bios is the only way to go to ensure a stable overclock.

Whatever happened to BF2 benchies?huges84 - Monday, November 7, 2005 - link

Wesley, any chance of a measurement of northbridge & "stack cool" heatsinks? If you or someone else with one could measure how high off the motherboard they rise, that would be great.I'm hoping the Thermaltake Big Typhoon or Thermalright SI-120 would fit, as they have somewhere around 2" raised off the board (though the heatpipes might still hit the northbridge heatsink :( ).

Nevermind.I have confirmed elsewhere the TT BT fits without any issues.
