ECS reserves the Extreme label for their top motherboards aimed at the computer enthusiast. While the Extreme boards have been very high on features, they have remained very affordable, often competing with boards that have much more modest feature sets. ECS decided some time ago that they wanted to go after the computer enthusiast; however, the path has been anything but a smooth one. As we have said in other reviews, it is one thing to aim for a board at the enthusiast market, but it is quite another to deliver the features and performance that enthusiasts really want.
Our last review of an ECS Extreme was in the Intel 915 roundup, where the ECS PF4 915P Extreme earned an Editors Choice in that huge roundup. For this roundup, we are taking a closer look at the ECS KN1 Extreme, based on the NVIDIA nForce Ultra chipset.
The ECS certainly has most of the BIOS options that an enthusiast is looking for. Memory voltage goes to 3.11V, which is significantly better than many top-name motherboards, which still have trouble supplying more than 2.8V as a memory voltage option. It would be better if options went to 3.5V, but in fairness, this range will provide the voltage needed for any memory except the high-voltage 2-2-2 OCZ VX and Mushkin Redline, which need 3.5V for best performance. Similarly, processor voltage options to +375mv are very adequate with today's CPUs, and the bus speeds to 400 and full range of processor ratios give users the option to make the most of the Athlon 64 capabilities. The only question that remains is whether or not the nice options mean anything on the KN1 Extreme; in other words, do they actually function?

There is nothing to complain about in the rest of the layout as ECS did a very good job on the KN1 Extreme. The ATX 24-pin and 12V 4-pin power connectors are on board edges where they belong. The IDE ports are in the ideal position, the 6 SATA ports fully clear the PCIe slot, and the additional connectors are on the bottom edge of the board, outside of the slot area.
ECS also thoughtfully included both coaxial and optical SPDIF out connectors on the rear panel, which also features dual-LAN (gigabit PCIe and 10/100 PCI) connectors. Perhaps manufacturers could label their dual LAN connections because even though I have a 50/50 chance, I seem always to plug the 10/100 when I'm looking for the Gigabit LAN. ECS also features a lime-green shroud with cooling fan for the power transistors, a feature more typical of Abit than ECS. All-in-all, the layout, feature set, and BIOS options are right on target for the audience that ECS hopes to attract.
We should mention in passing that, at first, we couldn't find the CPU ratios in BIOS. After complaining to ECS that there were no ratios, they pointed us to the Power Management tab, where Hammer FID controls were located. This certainly was not an intuitive placement for CPU ratios, although we do get the logic that Hammer FID or ratios are there because of Cool'N'Quiet, which is definitely related to Power Management. In any event, the ratios are there in Power Management, so we might save you a bit of searching.

Every single one of these MBs has a fan on the NB... where are the passively cooled mobos? The last thing I want is one or TWO more tiny fans just on the mobo to worry about failing...Zebo - Friday, July 22, 2005 - link
"someof you take Anandtech's word as the word of GOD"It's as close as you can get without dying.:)

Viper - You should come inside the forums for specfic help..dg3274 - Saturday, July 16, 2005 - link
The article states that the Abit board has a problem with 1:1 overclocking. I disagree. I think the problem is that it does not provide enough ram voltage to run the RAM at high 1:1 FSB. 2.8 volts is not enough to run ANY ram much higher than 280 or so FSB.Viper4185 - Thursday, July 14, 2005 - link
No one wants to help me with my n00b questions :(Marcel - Tuesday, July 12, 2005 - link
#67 I must be a little a slow …In the test “Maximun CPU Clock ( Lower Multiplier )”
For Chaintec, Abit, etc you use the multiplier in “11”, and only for Epox and DFI you use the multiplier in “9”, then you show a diagram with nothing more than the fsb.
http://images.anandtech.com/graphs/nf4%20ultra%20r...
The first question is WHY ?? there is no explanation for use different multiplier in the review. Not some guys, but ALL ones have better result in chaintec and abit with a lower multiplier.

Thanks Wesley, I did find you had checked HTT, and as I stated in my last post I don't understand what the problem was. But the deeper I looked into the review, the better job you seemed to have done, so sorry if I impied you didn't try very hard.DFI has a dual core (beta) bios available, dated 6-23-05
Epox has a dual core (release) bios available, dated 6-29-05
These were not used in testing.

#59 and #60 - One of the first articles I did a couple of years ago about Athlon 64 was how to overclock by manipulating HTT frequencies. I ALWAYS test manual HTT dividers I know should work for certain 1:1 memory clocks as well as Auto HTT if it is an available option.#58 - I was very CLEAR in the review that I tested with the BIOS that would allow the X2 A64 to work. We did check each board with an X2. That is the ONLY reason we tested and used very recent Beta BIOS'. Also there are 2 other very recent Chaintech reviews at other websites who had test results almost equal to what I found on the Chaintech, so there are at least 2 other Chaintechs loose with less than stirring overclocking. In the end, as I stated in the review, the Chaintech is a decent board, but at about the same price as the Epox, with poorer overclocking results, it was hard to give it an Editor's Choice this time around. The results found in this roundup should remove anyone's concern that we get cherry boards from manufacturers. I am a good overclocker, and very experienced in air overclocking and memory overclocking. What I got from these boards on air is all they could do with the TCCD memory that is all but standard test memory for motherboards these days. The capabilities of the memory we used is also well known and I tweaked for TCCD if settings were available if the board was not doing well at stock memory settings and our normal test timings.
I am really pleased some of you experienced better performance than I did with the Chaintech and Abit boards, but I can only report what I actually found in my tests. I don't think you come to AnandTech for a survey of what other websites or Forums found, because I find overclockers are notorious at exagerrating what they can reach with overclocks. We try to provide a consisten test environment for overclocking that will give repeatable overclocking results. Results, of course, always vary board to board, but having said that, OC results are usually pretty consistent on better boards from sample to sample.

Sorry, wrong link. that one was for the SLI version.http://www.foxconnchannel.com/productsDownload_mot...
