Chaintech VNF4-Ultra: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| Chaintech VNF4-Ultra | |
| 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) |
237x12 (4X HT, 2.5-3-2-7, 1T, 2.8V) 2844MHz (+18.5%) |
| Maximum FSB: (Lower Ratio) |
245x11 (2695MHz) (4X HT, 2.5-3-3-7, 2.8V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+22.5% Bus Overclock) |
The Chaintech VNF4-Ultra turned out to be a pale performer compared to the earlier Socket 754 nF3 Chaintech. While the VNF4 was excellent at overclocking at stock multipliers, its top end at reduced multipliers was a disappointing 245 clock speed, or 22.5%. This compares to over 300 clock speed with the top boards in this roundup.
That is not to say that the Chaintech is a poor overclocker. At stock multiplier, it can reach as high as just about any board in this roundup at a 18.5% overclock. However, if your approach to overclocking is to get the most from your memory by lowering multipliers and cranking up the memory speed, then you should choose another nForce4 Ultra motherboard.
Memory Stress Test Results:
Our memory stress tests measure the ability of the VNF4-Ultra 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: | 200MHz |
| 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 Chaintech required a 2T Command Rate with 4 DIMMs in two dual channels. This is the pattern seen on other top-performing Socket 939 boards. There was no problem running 4 DS DIMMs at DDR400 at the same aggressive 2-2-2-7 settings, which worked well with 2 DIMMs.

"If you looking to save even more money, the 9NPA, based on the nForce4 x4 chipset, has a street price of around $90. You give up the SATA 2 support and 1000 bus, but most of the performance features are still available in the same basic motherboard. "I think you're talking about the 9NPAJ motherboard, which uses the nForce4 chipset and supports "2.0 GTs HT FSB".

Regarding the post from ChineseDemocracyGNR on: Jul 9, 2005 3:19 PMQuoting statement from Anandtech's reviewer:

I agree with ChineseDemocracyGNR! To AnandTech:
No disrespect intended!
"Sorry to say, but i believe your statement is wrong".
The Epox Model # EP-9NPA+Ultra MoBo does support Sata-2 drives.
I don't know where you got that incorrect info.
Also, i'm not sure what you are refering too about your other statement about "giving up 1000 bus"? It supports 2000 bus.

HTT's multi's were listed in the review.I have confirmed that the Chaintech's 6-03 bios overclocks just fine with single core cpu's.
Phiro, I understand your point, and it is a good one.
For me Anandtech reviews are one of my primary tools for deciding what hardware to buy. I think it is the same for a lot of people. Anandtech has earned this trust. That is why this review is disturbing. The results do not match my experience. You might notice in my previous posts, that I have followed false trails trying to figure out why. I cannot explain why the Chaintech board (and others with experience with other boards) performed so poorly in overclocking.
The reason this is imoportant is that the final ratings follow the philosophy stated in the beginning, that a better overclocker is a better board, because the actual performance at stock speeds is equal.The application testing bore this out.
Us 'bleeding edge" guys are well aware of how very small changes can make a big difference in performance. The fact that the award winners were using bios's not available to the public ( I have just now rechecked) that are dated a few days after their most recent bios, (for dfi, a beta which carries no warrantee support, their last release bios (the one that will be on the board you buy) is dated in March), throws the final results into doubt. In other words they appear to be special bioses for this test.
In the past, Anandtech has been very forthcoming when using a beta bios, explaining why, and stating that the board maker will make it available, or the included features available in a release bios. This was not done, they were not even labeled as beta's.
When Anandtech labels a board as an award winner, it is giving it's seal of approval, that people such as your self and myself will factor in when making a buying decision. The truth is under your criteria, any of these boards will serve you very well. From the application tests, your decision should be based on a) a good match to your programs, b)features you need or think you may need, and c) price. Anandtech's recommendation is irrelevant.
Anandtech's "forum-bleeding edge" audience is larger than you assume in your estimate. The fact that you are looking at an nVidia board at all says you are very involved in you purchasing decisions, other wise you would let some one else handle it for you. "gimme something that works" would be your involvement.
Anand awards have been given to 2 boards that you cannot buy, or so far even upgrade, to "as tested".
Speaking for myself, computer hardware is hard to keep up with, and losing a rock like Anandtech will be a great loss. I hope that will not happen, but excellent sites do fall by the wayside if they slip too far.
Phiro - Friday, July 8, 2005 - link
I think Anandtech has their audience nailed down about 80% of the time - their one flaw is listening to their forums a little too much IMO.Too many people have posted "oh what a dumb review we already bought our motherboards blah blah blah" - a GOOD example of not listening to the forums. If you're posting on the forums, you've probably been here for some time and you're in that 1% of computer users who qualify as "bleeding edge". Anandtech doesn't want to constantly address just the bleeding edge audience - as fun as you can be, you're 1% of the market, and for every right decision you make, you make wrong decisions.
To rip on Anandtech a little bit though, they do listen too much to the forum overclockers. The vast majority of users have NO interest in overclocking. 4% higher framerates isn't worth goofing around with voltages and installing a water cooling system.

I think its funny that so many people are now like, "Epox is the best" "they OC the best" "I'm gonna get one of those Epox NF4 boards that Anandtech reviewed". I have told you for months that Epox is nice, and to get the 9npa+, and great reviews have been floating around for a long while now. someof you take Anandtech's word as the word of GOD. That is hilarious and I guess its to be expected out of the mainstream audience that reads Anandtech.About the 9npa+ and 9npa SLI, OFFICIAL dual-core BIOS's were just released today by Epox. Enjoy.
TheGlassman - Friday, July 8, 2005 - link
Good question. It could explain the problems experienced with most of the boards. The chipset will run well over 1000 with no problem, but 1200ish will cause the boards various problems, usually a reset to a safe mode.Peanya - Thursday, July 7, 2005 - link
Hmm I wonder if they tried a 3x LDT multiplier on some of those boards. I'm thinking that's why the Abit wouldn't get past 250MHz. I've not only seen reviewers get well past there, but many users. Some brands automatically lower the LDT for you, whereas some do not. Was this taken into consideration?AtaStrumf - Thursday, July 7, 2005 - link
MOBOs have always been messy things to test, debug etc. The thing I hate most is changing the MOBO, because there are so many possible problems associated with it.I do have one HUGE gripe with this roundup. You chose to test DFI's non SLI board as a control for SLI/Ultra boards, but that happens to be the worst possible choice. Why? Because, as you pointed out yourself, that is exactly THE SAME board, with just one pin on the chipset shorted/cut. For control you should have tested the worst case scenario, like a physically different board (just one PCIe 8x/different layout, feature set) possibly a newer revision. This brings us to the biggest problem with this kinds of assumptions and MOBO testing in general. Different versions, REVISIONS, bios', different memories, variable sample-to-sample MOBO quality, and now to top it off, different Athlon CPU revisions. I definately think you should not have made the assumptions that you did and should have tested ASUS, MSI and GIGABYTE NF4 Ultra boards. They are afterall one of the biggest enthusiast MOBO manufacturers.
If you want to keep your reputation you should definately pay more attention to this sort of things. Don't rush so much! You don't have do a roundup, post individual board reviews and take more time with them. Like you did with the DFI! You should even get at least three samples of each MOBO from different sources and compare them in order to really be able to get reliable results. Forum posts from other people can be very misleading, because of all the variables and skills these people have. This would make you THE BEST ;-) As things stand now, you're pretty mediocre I'm afraid.
One typo I found:
Page 19:
Our past tests have shown performance of the AGP-8x and PCIe **688** Ultra to be virtually identical
Probably 6800 ;-)

1) Wesley next time please can you post instructions of how to run memtest to determine the best tRAS rating for your memory. I emailed you in your last article and received no response. Yes, I am a n00b. Perhaps someone else can tell me :P2) I have the same memory as you, how do I check if it is TCCD or TCC5?
3) You don't actually say which ethernet controller is better, the Marvell or the NVIDIA?
4) I think it was a big mistake for you to leave out the Gigabyte boards. For those that are interested in the Gigabyte boards compared to some of the above check out this review.

Otherwise good review, thanks Wes. Hopefully you can answer Q1-3 or someone else :)

Hum.... Chaintech VNF4-Ultra can reach 275+ FSb easily, there are so many users here that can say same thing as me....There is something strange on the results, i can bet that other mobos on the round-up can reach high mhz too....
Look this:

Is with my chaintech, i think that you are cheating things here...
