The Chaintech was one of the motherboards that we had looked forward to testing. It is very inexpensive, and the last Chaintech that we tested, the Socket 754 VNF3-250, was an Editors Choice for value. Chaintech has repeated an outstanding selection of useful overclocking adjustments in the VNF4-Ultra BIOS. The features are also first rate for an Ultra board selling for $89 street price, with Firewire being the only missing feature of importance to some buyers. Even the excellent NVIDIA "any-drive" RAID for SATA 2 and IDE is fully supported, along with the standard NVIDIA chipset-based Firewall and LAN features. Chaintech has also implemented a really nice boot screen option. When selected in the BIOS, the boot screen shows post codes during boot so that you can see exactly what is going on and where problems might be.

The only real compromise that Chaintech made with the smaller board was placing the 24-pin ATX and the 4-pin 12V between the CPU and rear panel connectors. No matter how you run the bulky 24-pin cable, it gets in the way of something - memory or CPU or IDE/SATA connections - and none of the routing options is really a great choice. Chaintech builds to a price point, and if this is the concession that had to be made for performance, we will find a way to live with it. That doesn't mean that we have to like it though.
At first, we thought that Chaintech had omitted an optical or coaxial SPDIF port, but looking closer, we found that the top left audio port (the blue connector) does double-duty as an optical SPDIF out port.
When we first received the Chaintech for evaluation, it was supplied with a passive heatsink for the single-chip nForce4 Ultra chipset. Chaintech sent an announcement that they had updated the design for active chipset cooling due to high temperatures with the nF34 chipset. Soon thereafter, we received an active cooling kit for the VNF4-Ultra that was a very easy installation. Chaintech tells us that current boards should be equipped with active cooling for the chipset.

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.

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...

Foxconn has a BIOS release that allow for multiplier adjustment.http://www.foxconnchannel.com/productsDownload_mot...
