When the Asus A8N-SLI Deluxe was first introduced, prices were in the stratosphere. However, after several weeks on the market, prices have settled solidly below the $200 price point. Several online retailers now offer the Asus SLI in the $175 range. The feature set and Deluxe name are generally reserved for Asus for their "notch-down" boards, which might indicate that Asus has plans for a top-line Premium board in the future.

The Asus is unique among the tested SLI boards in providing 3 slots between the x16 PCIe slots used for SLI. All of the other SLI boards provide 2 slots between the video cards. This will be an important feature for users who water-cool their video cards or have special cooling in mind for the pair of SLI cards. As you will see later in our overclocking test, however, this capability is basically wasted, since this Asus is not a particularly good overclocker. Lately, Asus has stood at or near the top in overclocking, but that has been truer of Asus Intel solutions than those for AMD.

We have commented before that Asus pays close attention to the layout of their motherboards, and that also shows in the A8N-SLI Deluxe. Connectors are all where they should be - IDE, floppy, ATX and 12v are all conveniently located for easy access. In fact, our only real complaint is the so-called EZ-plug that Asus uses to provide more power to SLI. It is bad enough that two top-end video cards require 4 Molex connectors to power them, but on the Asus board you also have to connect another 4-pin Molex for additional video card power. Asus says that this is required for "stable SLI operation", but the other 3 SLI designs do fine and are quite stable without the 5th power connector.

In its favor, the Asus was the only SLI board that allowed you to change the setup from "normal" to "SLI" without having to first remove the video card. The design of the PCB was also the best of the group with positive side locking that looked like it might survive a few changes. We also very much liked the locks on the video slots because you could release them from the back of the slot as well as the front - a real plus with double slot cards.

The feature set on the Asus is just average in this roundup. There are two gigabit LANS, but #2 is PCI instead of the faster PCIe. Audio is the rather average Realtek 850 with nothing special in the Asus implementation - quite a step down from the leading edge designs of some Asus boards for Intel processors. Firewire is also 1394a, or Firewire 400, when Asus uses Firewire 800 on their recent Intel boards. Another way to put this is that this Asus A8N-SLI is certainly not up to the high design standards that Asus has set for their recent Intel designs. Perhaps there is another Asus SLI in the works that will do a better job at bringing high-end features to Asus nForce4.

The storage area is an area where it first appears that the Asus stands out. Asus fully supports the nVidia SATA 2 and IDE any drive RAID features, and then offers an additional Silicon Image 3114 SATA RAID controller that even supports RAID 5. In the end, 3 of the 4 SLI boards provide the same Sil3114 controller, which is SATA 1, and does not support SATA 2 drives.

The Asus is certainly a competent SLI motherboard, but it is pretty average in this roundup and does not stand out in any way other than the wide space between the video slots. Add to this below-average overclocking abilities and the problems experienced with our 6800 Ultra cards on just the Asus board, and it is hard to get too excited about this particular Asus board. Asus engineering is an important benefit with any Asus product, and the resources of this giant company are impressive. But as you will see in the roundup, there are better choices among the SLI boards available.

    I thought this link would be rather important to see:

    You make a big deal out of the fact that the DFI can hit 318 but they both do the same 2.8 ghz, users won't see much difference, if any.

    Asus: Maximum OC:
    (Standard Ratio) 234x12 (Auto HT, 2-3-3-7, 1T, 2.8V)
    2808MHz (+17%)
    Maximum FSB:
    (Lower Ratio) 255x11 (2805MHz) (4X HT, 2.5-3-3-7, 2.7V)
    (1:1 Memory, 1T, 2 DIMMs in DC mode)
    (+28% Bus Overclock)

    DFI: Maximum OC:
    (Standard Ratio) 238x12 (Auto HT, 2-3-2-7, 1T, 2.9V)
    2856MHz (+19%)
    Maximum FSB:

    Don't know if anyone's noticed yet, but I just took a trip over to MSI's website, and guess what? Only the SLI mobo has the Creative chip. The Neo4 (i.e. nF4 Ultra chipset) mobo uses the Realtek ALC850. I for one was disappointed...
    That makes for an interesting decision: the SLI board is still cheaper than the Ultra board plus a Creative 24-bit sound card. Hmmm...

    New PCI card with C-Media DDL chip: http://www.avsforum.com/avs-vb/showthread.php?s=&a... ge=20&pagenumber=1

    Currently only available via ebay apparantly:
    http://search.ebay.com/HDA-Digital-X-Mystique-7-1-...

    If it has the same performance as Soundstorm remains to be seen. Reading the thread the EAX support is just as dodgy as it was on Soundstorm.

    What chipsets did your USB and firewire drives have?

    thanks for the great review!
  • bjorn44 - Thursday, March 3, 2005 - link

    Anyone know how they did the memory benchmark with memtest86 3.2? I can't find any option for testing bandwidth.

    Thanks,

    Well if it's any consolation, PCSTATS have updated thier site review of the MSI Neo4 Plat SLI (and will probably make two more updates to it)
    - now states 96Khz
    - will modify DICE statement
    - they are indicating that the sil3132 can do raid5, but I'm not sure that it can...

    Wow Roomraider, that's quite the system you have there.

    #82 u r absolutely correct sir. I have the top SB card available(Audigy 4 Pro)& the only way i get DTS or Dolby Digital of any form is SPDIF out Via Coax or Fiber optic cable with settings for (Passthrough) to my Yamaha 7.1 Amp.

    I admit this is slightly OT, but as I first got excited about the possible DD-encoding feature on the MSI-mobo and then let down by the obvious lack of it, I was happy to find these news:

    http://news.designtechnica.com/article6709.html
    http://www.engadget.com/entry/1234000683034067/

    I know many of us don't like the DRM/HDCP-features of HDMI, but HDMI certainly is the way to transmit high-definition, multichannel audio *without the need* to compress ie. encode to DD. And live content, such as games, would not probably have the copyprotection flags on, anyway. Of course, getting enough coverage for HDMI in both h/w and s/w will take time, but I bet this is the way it's ment to be played in the near future.

    For example, think about combining this with s/w generated mc-audio and Intel HDA. No need for badly implemented codec/DAC in this model. Of this combined with discreete graphics card and the audio generated with the help of vector processing on the card.. I just hope Intel/Nvidia/ATI/whoever would start a strong enough, open standard to compete with EAX. Then Creative would either have to run, fast, or join their forces.

    Meanwhile, because there is not much HDMI-support (except for the earlier, non- multichannel-high-def-audio-supported HDMI-standard, for mainly graphics) some solution providing DD-encoding to be sent over standard S/PDIF would still be very, very desired for many of us.

    I end this thread-hijacking attempt here and apologize if being OT. Now back to our regular programming... :)

    Wbr, Tatu
