ECS KN1 Extreme: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| ECS KN1 Extreme | |
| Processor: | Athlon 64 4000+ (2.4GHz, 1MB Cache) |
| CPU Voltage: | 1.55V (default 1.50V) |
| Cooling: | Thermaltake Silent Boost K8 Heatsink/Fan |
| Power Supply: | OCZ Power Stream 520W |
| Memory: | OCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips) |
| Hard Drive: | Seagate 120GB 7200RPM SATA 8MB Cache |
| Maximum OC: (Standard Ratio) |
235x12 (Auto HT, 2-3-2-7, 1T, 2.85V) 2820MHz (+17.5%) |
| Maximum FSB: (Lower Ratio) |
235x11 (Auto HT, 2-3-2-7, 1T, 2.85V) 2585MHz (+17.5%) Lower Ratios reset to Stock Multiplier |
Reality bites when we begin overclocking the ECS KN1 Extreme, since the ratios that we had such a time finding really don't work very well. As long as we stay within about 1.5X of stock speed, the ratios work, but beyond that, the board resets whatever you set. That means that we couldn't get 10 or 9 to work with a 12X 4000+ CPU. The stock multiplier overclocking was competitive at 235 with top boards, but the inability to set ratios reliably had seriously limited bus overclocking. The best that we could do was the same 235 at 11, which we reached at stock 12X. This was really a disappointment for a board that we thought might break away as a great value. For stock performance, the ECS is fine; for modest overclocking, the ECS performs well; but for the enthusiast, the KN1 is anything but extreme.
Memory Stress Test Results:
Our memory stress test measured the ability of the ECS to operate at its officially supported memory frequency (400MHz DDR), at the lowest memory timings that OCZ PC3200 Platinum Rev. 2 modules will support. All DIMMs used for stress testing were 512MB double-sided (or double-bank) memory. To make sure that memory performed properly in Dual-Channel mode, memory was only tested using either one dual-channel (2 DIMMs) or 2 dual-channels (4 DIMMs).| Stable DDR400 Timings - One Dual-Channel (2/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
Using two DIMMs in Dual-Channel 128-bit mode, the memory performed in all benchmarks at the fastest 2-2-2-7 timings at default 2.6V voltage.
Tests with 4 DS DIMMs on an AMD Athlon 64 system are more demanding, since AMD specifies DDR333 for this combination. However, most AMD Athlon 64 motherboards combined with recent AMD processors (the memory controller is on the AMD CPU) have been able to handle 4 DIMMs at DDR400.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs populated) |
|
| Clock Speed: | 166MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
Tests with all four DIMM slots populated on the ECS KN1 Extreme boards required a 2T Command Rate with 4 DS DIMMs in two dual channels at a speed of DDR333. Despite the fact that AMD recommends DDR333 with 4 DS DIMMs, most motherboards do support DDR400 at 2T with 4 DS DIMMs.

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...
