DFI nForce4: SLI and Ultra for Mad Overclockers

Overclocking: DFI nForce4
With DFI's reputation as an overclocker's board, and the incredible range of tweaking options available in the BIOS, everyone is expecting incredible overclocking performance with the new DFI nForce4 boards. They will definitely not be disappointed.
| Front Side Bus Overclocking Testbed | |
| 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 IDE 8MB Cache |
| Maximum OC: (Standard Ratio) |
238x12 (Auto HT, 2-3-2-7, 1T, 2.9V) 2856MHz (+19%) |
| Maximum FSB: (Lower Ratio) |
318x9 (2862MHz) (Auto HT, 2.5-4-3-7, 2.9V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+59% Bus Overclock) |
The DFI nForce4 boards shredded all previous records with this CPU and memory - reaching the highest overclocks at stock speed and at a lower mulitiplier that we have ever tested with this combination. We have squeaked by the 300 CPU clock frequency (DDR600) in the past, but it always required a 2T command rate. This time, we reached an astounding 318 (DDR636) at 1T, at the rather aggressive memory timings of 2.5-4-3-7 with our standard OCZ PC3200 Platinum Rev.2, which is based on Samsung TCCD chips. This is the highest DDR speed that we have ever reached with this memory or any other double-sided DDR memory.
What impact does 318 have on performance? Quake 3 ran at 642FPS and SiSoft Sandra 2004 standard memory bandwidth was 8,300 MB/s. The Sandra unbuffered memory bandwidth was at 4000 MB/s. All these results are new performance records in our memory testing. The very wide range of memory voltages to 4.0V is particularly useful in reaching the highest possible overclocks, along with a very complete set of memory tweaking options in the BIOS. There is still a huge reserve in the available memory voltage range as we only needed 2.9V to reach these performance levels. Those with exotic cooling will appreciate that the CPU voltage and memory voltage settings on the DFI will give them what they need to squeeze every bit of performance from their CPU and memory.
DFI delayed final release of both nForce4 boards to update some 20 components on the board and to make further modifications to BIOS timings. The goal was to improve memory compatibility and further improve the already stellar overclocking abilities of the engineering sample. Compared to the engineering sample board that we tested, the final retail board is a much better overclocker. The update certainly appears to be a success, and DFI tells us that all retail boards, the boards coming off the line, have the modifications and new BIOS.

It's been a year or two since the last time I researched motherboard features, so maybe I'm out of the loop. Isn't it unusual for a consumer level motherboard to offer RAID-5? This is certainly the first such board I've heard of. I wonder if the RAID-5 support is hardware or software based.ChineseDemocracyGNR - Wednesday, February 2, 2005 - link
#17"Few questions can you fit say a x1 pci-e card into a x4 pci-e slot??? "
Yes you can.

#18 Would you consider a 100m sprinter who broke the old world record by 8% to have demolished the record? What you have to realized, is that these boards are performing at the very edge of what's possible today. While a compact car exceeding the Chevy Cobalt's top speed by 8% would make everybody yawn, a car that exceeds the Bugatti Veyron's top speed (252mph) by 8% would be pretty remarkable.Irregardless, this looks to be a very respectable board whether you want to OC or not. For the features that are on the board, $140 for an nforce4 board isn't all that bad. And just like the S754 board, I'm sure the price will come down significantly after a little while.

Man, I remember we used to laugh at DFI back in year 2000; How was it possible for a low-end maker to became the best brand for all die hard overclockers? someone should write a book about it...Manzelle - Wednesday, February 2, 2005 - link
*yawn*Where are the AGP/PCIe boards...better yet, where is DFI's nForce3 939 board...

1. why another board maker don't try to make motherboard likes DFI Ultra have ? Because it's a big oppurtunity to buy Ultra than SLI2. What do u think Nvidia do to make this board DFI Ultra not functionally likes SLI ? Just tweak driver or likes AMD in the past, change chipset in their factory ? so people can't do likes anand do.

I do not like this phrase from Final Words:We reached 318x9 at 1T Command Rate - performance that demolished our previous best of 295 1T with this same memory.
This is a gain of 8% over old result. Would you consider a car with maximum speed 8% higher than competitor model to be "demolishing" it? I don't think so. I consider this to be a "fair improvement" over previous result, and not a "demolishing" one.

Few questions can you fit say a x1 pci-e card into a x4 pci-e slot???4 volts for RAM but your going to need active cooling, and how do you manage that.

I dont see what all the shouting is aboutSure its a nice board, but, unless you are an EXTREME overclocker the NF3 is plenty close enough, and the big surprise here is the Epox

I was hoping for a look at results of other memory as well, besides only the ocz ddr400. Perhaps the upcoming round up will use various memory sticks.
