ECS hopes that the bronze-foil box with a feature flap clearly announces that the ECS KV2 Extreme is a premium board. The Extreme name is reserved for the top ECS boards, and with the Socket 939 currently a premium board, the KV2 announces that ECS wants to be a contender at the top.

The KV2 Extreme even has the individual interior boxes that we first saw on Abit motherboards, carefully fitted to protect the manuals and brackets . This should not come as a complete surprise, since ECS also manufactures some motherboards for Abit. The KV2 is a 6-layer, 3-phase design, which includes all the bells and whistles that you have come to expect from top-of-the-line motherboards. This includes Dual RAID, Dual LAN, 4 SATA ports, 2 Firewire ports, provisions for 6 IDE drives, and active North Bridge cooling.



Just so you don't miss it, ECS even has a silver plaque on the purple KV2 announcing it is a member of the Extreme series. The layout of the board is generally excellent, showing great attention to the smallest details. ECS has placed the ATX, IDE, and floppy connectors in our preferred upper right edge location. Even the extra IDE for the 5th and 6th IDE is out of the way for the PCI slots.

The BIOS adjustments on the early versions of the KV2 were very sparse, but ECS quickly updated the KV2 Extreme with the CPU Frequency adjustments, ratios, and PCI/AGP lock that you would expect on a premium 939 motherboard. Our only complaints about the available options are that the vCore is still rather meager with a top of 1.55V; 1.70 volts would have been preferred. Also, the vDIMM to only 2.7V is low for a board that intends to compete in this arena - a range to at least 2.85V and preferably 3.0V would be better.

The range of CPU Frequency adjustments to 511 is incredible, but we found that we could only use a very small portion of that frequency range. While we verified that the AGP/PCI lock is working with a PCI Geiger, we were still limited in our overclocking attempts compared to other VIA boards in this roundup.

    I am using the Gigabyte 939 NF3 board for the past week now. It appears that their are two lan connections listed as Marvell (lan 1) and Nvidia (lan 2). I have been using the Nvidia one?

    To get the firewall to function with the Gigabyte board all you have to do is download the Nvidia 4 in 1's after installing the Gigabyte drivers.

    Of course I'm a noob.

    #70 - The nVidia fiewall is a port on the chipset that allows for direct communication with the Gigabit chip PHY layer. It is therefore very difficult to determine if the on-chip port is being used just from looking at the specifications.

    Earlier this week we asked nVidia for help in identifying which motherboards were using the on-chip gigabit port. nVidia is looking into the list of boards we supplied and said they would be providing us with updated information soon. When we receive that info we will post it.

    Any chance to have tested the OCZ 4000 gold rev 2, with the 2.5-3-3 latencies and compare that to the 3700 EB?

    Curious as I narrow down things.

    Any news on Pci-e for AMD64's?

    Thanks!

    i too would like to know whether the Gigabyte NF3 board uses the nVidia NIC/firewall, and if not not, why anandtech failed to mention the fact?

    What is the noise difference in the retail packaged CPU fans in this class (S-939), and the Thermaltake Silent Boost K8 used in the reviews.

    I notice that Thermaltake also has another CPU cooler using heatpipes, the SilentTower 4-in-1 CPU Cooler. Have you guys tested this out?

    My current PC (AMD XP 1800+ with the equivalent of a Volcano 9) gets too loud for me when it gets warmed up, and that's with it sitting on the floor next to my desk.

    #62, you must have read the post incorrectly. I was hoping you would have used the same CPU, which you did not. Somehow you read the opposite. I figure in comparing the chipset to the other, using a different CPU throws in a ton of extra variables. Now if you are looking at it from a prospective of which is faster, then your setup is fair. Of course most people would buy the Northwood on the 875 but it becomes more of a platform benchmark rather than anything that could be called a chipset competition.

    About the FX53, one reason I do not like you using it is because it is AMD's flagship product and at least from what I remember, the Presscott that you used was not an EE. Even so, the biggest bother is that the FX53 will always cost more than $500 and very few people will actually ever buy it when they can get so much more band for their month with just a regular class AMD64. This is the case with the EE too, they will always cost an arm and a leg so I'd say only about 5% of people will be buying the FX and the EE series chips. By an overwhelming majority, most consumers will be buying the non-enthusiast parts.

    Please take this as the official responce to the rumours about 3500 and 3700EB.
    We have NOT stopped production of these modules, it sells quicker than we can produce it..that is the only real issue.

    We have just shipped another huge order so please go bug your favourite stores to stock it..

    EB is here to stay at least for the time being.

    Also, has the performance discrepancy with Halo and the nforce boards ben figured out yet? If it somehting that may resurface in other games ill get an nforce board. If it is fixable or just a one off with halo, i can save a few $ and get a via board while i am waiting for PCIx...

    Does the Gigabyte board use the Nvidia LAN as well? I see it says marvel but after the last series of posts with the marvell/nvidia chipset i am confused now...

  • Anemone - Monday, July 26, 2004 - link

    Thank you for enlightening on the LAN issue with the NF3 ultra - for me I'm getting and FX.

    Since this article is getting referenced a lot with people I talk with and such, can we keep a front page link to it for a while?

    Also looking forward to memory reviews as well. Rather sad the 3700EB has been discontinued :(
    Hopefully OCZ will have something better to take its place in not too long, but that might be impossible.
