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.

Why is the A8N missing from the comparison?Zebo - Thursday, February 3, 2005 - link
WHAT BIAS??? Please spell it out for me as I don't see it. This a bad arse mobo... I wager best Wes ever seen and used in years of comp building time... I'm suprised he's not even more animated... and even to dwell on insignifigant "short comings" later in article shows me he was giving a fair shake...leaving "best" PCIe 939 title open even though he knows in back of mind DFI already won...:)byvis - Thursday, February 3, 2005 - link
#55 I agree that this board is very good in overclocking and etc... But I'm telling what I thoughts came to me reading this article. Until now I haven't read such biased and praying article. Everything has drawbacks, even ultra extreme mbs... Professional shouldn't express their opinion like this. I can, you can, but not professionals... This is ofcours IMHO :) So don't flame me :)erios666 - Thursday, February 3, 2005 - link
#60 - Ha! Excellent point Zebo and I'd have to agree. As an enthusiast I'll take care of the sound myself thank you. Just as I would the video.Zebo - Wednesday, February 2, 2005 - link
Cheeezzzusss...some people....LOL get em flexy.
Also those people complianing about sound are kinda weird. even if they put 880 or SB live on there it's still crap if you're at all interested in hifi. Plus it adds $20 to mobo cost... for "just ok" sound. NO THANKS. I'd prefer they drop sound all together (save $8+) as this is an enthusiast board.. not an all in one..notice thiers no on-board graphics?

The message is clear: DDR2 has failed! DDR636 at EXTREMELY reasonable latencies--color me impressed.I'd like to see how this board handles Crucial's Ballistix RAM, since Ballistix is pretty cheap on the Egg (~$220 for the pair of 512MB sticks) and performs like TCCD; would be interesting to see what the DFI can take the Micron chips to, considering the legs it gives to TCCD chips...

#54: Considering Abit's best engineer, Oscar Wu, has been working for DFI for a while, I doubt Abit will change much. Abit's last good board was the NF7-S. Since then, they seem to have gone downhill. DFI has only been improving.flexy - Wednesday, February 2, 2005 - link
my bad..nevermind...i confused the MSI board with the dfi....the dfi is NOT the one with the onboard sb live :)flexy - Wednesday, February 2, 2005 - link
#42, you can have the SB live onboard sound with the SLI-DR...well....and the Ultra ius cheaper and comes with the crappy sound. WHO CARES ????I got a Audigy 2 Value for $42.
If you NEED the good onboard sound..then get the SLI-DR board....if not get a pci soundcard.

>>>The board is nice, but not outstanding, incredible, top performing, etc... Jesus AnandTech I have never seen you so biased. I hope that the benchmarks don't lie. Poor preview, poor...
>>>
ehrm...its the best and fastest enthusiast's NF4 board right now with the best overclocking capabilities AND a way to "mod" it to a SLI...what do you want more ? Cheeezzzusss...some people....
