When Asus first introduced the A8V Deluxe it was the only Socket 939 board we had received with no AGP/PCI lock. Asus did not advertise an AGP/PCI lock and, in fact, it was not even listed as an option. When we talked with Asus about why they would leave out such a key feature of the VIA K8T800 PRO chipset, we were told Asus had concerns about the stability of the feature, and would not release a board with a lock until they were confident of the stable operation of the feature. While we did receive several prototypes with impressive performance and a working lock, Asus US did not give us the go-ahead that these interim designs would ever become production boards. For that reason, we did not believe it was fair to AnandTech readers to review an excellent design that they might never see in production.



Several weeks ago, Asus advised that they had completed a new Revision 2.0 with a number of board refinements and a working PCI/AGP lock that would soon be released. We had been very pleased with the revisions of the A8V we had evaluated, so we had great expectations of Revision 2.0. As you will see in the performance numbers and overclocking of the Asus A8V we were not disappointed.

The A8V Deluxe is the top-of-the-line Asus board for Socket 939, as you see reflected in the feature set. The A8V can be considered an update of the successful Asus K8V with the significant addition of the VIA K8T800 PRO chipset with, finally, a working PCI/AGP lock. Asus tells us that Revision 2.0 is more than just the addition of a production PCI/AGP lock, as they also used the update as an opportunity to refine the design.

As the Asus flagship Socket 939 the A8V Deluxe provides all the expected VIA K8T800 PRO/VT8237 features like 2-drive SATA RAID, 8 USB ports, and Hyper Transport to 1GHz. In addition Asus adds Marvell Gigabit LAN, The Promise PDC20378 RAID controller supporting 2 more SATA drives plus an additional IDE connector, Firewire, and the Realtec ALC850 8-channel codec. Asus calls their top boards AI, and the A8V includes a long list of proprietary Asus AI features like C.P.R., AI Net, AI BIOS, EZ Flash BIOS, and Q-Fan 2 fan-speed controls. The A8V also fully supports AMD Cool'n'Quiet.

Too often, we forget to mention that Asus is a huge proponent of Wi-Fi, and most of their boards include Wi-Fi capabilities. The A8V Deluxe is another Wi-Fi Home board, but the included adapter is now the higher-speed Wi-Fi G instead of the older and slower B standard. Asus even includes a desktop antenna to ease your communication with a wireless router or to serve as host for other Wi-Fi computers.

The overclocking controls are excellent in their range as we have come to expect on Asus boards. Noteworthy are the ratios in fine 0.5x ratios which makes OC fine-tuning that much easier on 939 CPUs. The CPU voltage also covers a very wide range from 0.8V to 1.80 volts. Our only complaint here is that 300 CPU Clock is a little short for a board that can do 289 at 1:1 memory, and the memory voltage controls are really limited at a top of 2.8V when we have performance memory warranted to 3.0V. Otherwise the variety and range of BIOS adjustments is excellent.



The layout of the A8V Deluxe is excellent. Both the 20-pin ATX and the 4-pin 12V connectors are on board edges and don't interfere with the CPU. The IDE connectors are in our preferred upper right edge of the board. Some will hate the floppy edge connector, but we liked getting it out of the way, and the floppy is also a connector many users don't use any way. The 4-dimm connectors, for up to 4GB of Dual-Channel memory, are well clear of the AGP 8X slot when changing memory. Asus is an advocate of quiet, failure-free passive chipset cooling, and you will see that in the massive heatsink used on the Northbridge. There's little to complain about in the layout of the Asus A8V Deluxe Rev.2.

Rear panel I/O is also very complete, including 6 audio mini jacks, both optical and coaxial SPDIF outputs, 4 USB, LAN, Firewire, 1 serial port, parallel port, and the usual PS2 keyboard and mouse ports. We were particularly pleased to see easily accessible optical and coax SPDIF ports and wish other manufacturers paid as much attention to this feature as Asus has in their recent board designs.

    Also, networking benches would have been nice (throughput and CPU utilization). It would be interesting to see what kind of impact Gigabyte going with a 3rd party ethernet controller has in comparison to the MSI board using the NF3's controller.

    On a somewhat related note, when will the Neo2 actually be available for purchase?

    How about telling board makers to use better Sound for their boards.

    I got my board as it came with a VIA Envy soundcard. When I see RealTek sound that tells me they don;t care about quality, but about what they can say comes with the board.
    Even C-Media has a new full (non-ac97) soundchip out now that can;t be that much more then a realtek 850/650/655 chip.

    #7,8,9 - Corrected. Since ECS did use a SiS chip on their VIA board for secondary RAID, I got confused and spread the chipsets around :-)
  • Stefpet - Tuesday, July 20, 2004 - link

    ...but when will we see K8T890 or nforce4 motherboards?

    I don't want to be forced to replace the motherboard with a new one to get that top performing PCI Express card later...

    Final words, somewhere in the middle of the page:
    "The ECS is a remarkable step forward for ECS"
    :c)

    Great work, though.
  • RyanVM - Tuesday, July 20, 2004 - link

    Silly me, I meant ECS, not Epox.
  • RyanVM - Tuesday, July 20, 2004 - link

    "8 USB 2.0 ports supported by nF3-250" for the K8T800PRO-based Epox KV2?
  • Wesley Fink - Tuesday, July 20, 2004 - link

    #4 - Corrected. With more than 9000 words a number typo seems inevitable.
  • BLHealthy4life - Tuesday, July 20, 2004 - link

    Still can't find the MSI K8n Neo2 mobo for sale anywhere.

    Been waiting and waiting....and waiting some more...

  • AkumaX - Tuesday, July 20, 2004 - link

    Our FX53 topped out at about 2.59 GHz on the ECS KV2, which is slightly below the 3.6+ achieved on the top 939 boards
