DFI LANParty nF4 SLI-DR: Overclocking and Stress Testing
Overclocking
| Front Side Bus Overclocking Testbed | |
| DFI LANParty nF4 SLI-DR | |
| Processor: | Athlon 64 4000+ (2.4GHz, 1MB Cache) |
| CPU Voltage: | 1.55V (default 1.50V) |
| Cooling: | Thermaltake Silent Boost K8 Heat sink/Fan |
| Power Supply: | OCZ Power Stream 520W |
| Memory: | OOCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips) |
| Hard Drive: | Seagate 120GB 7200RPM SATA 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 set new 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 reached a very satisfying 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.
As we detailed in our DFI review, DDR636 translated into a 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.
Memory Stress Tests
Our memory stress test measures the ability of the DFI 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 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 DFI nForce4 boards required a 2T Command Rate with 4 DS DIMMs in two dual channels. This is the pattern seen on other top-performing Socket 939 boards, but we hoped higher voltage might allow us to eek out 4 DS DIMM 1T performance. However, additional voltage did not help and DDR400 with 4 DS DIMMs still required a 2T Command Rate on the DFI nForce4 boards.

I thought this link would be rather important to see:http://forum.msi.com.tw/index.php?topic=82427.0

You make a big deal out of the fact that the DFI can hit 318 but they both do the same 2.8 ghz, users won't see much difference, if any.Asus: Maximum OC:
(Standard Ratio) 234x12 (Auto HT, 2-3-3-7, 1T, 2.8V)
2808MHz (+17%)
Maximum FSB:
(Lower Ratio) 255x11 (2805MHz) (4X HT, 2.5-3-3-7, 2.7V)
(1:1 Memory, 1T, 2 DIMMs in DC mode)
(+28% Bus Overclock)
DFI: 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)

Don't know if anyone's noticed yet, but I just took a trip over to MSI's website, and guess what? Only the SLI mobo has the Creative chip. The Neo4 (i.e. nF4 Ultra chipset) mobo uses the Realtek ALC850. I for one was disappointed...That makes for an interesting decision: the SLI board is still cheaper than the Ultra board plus a Creative 24-bit sound card. Hmmm...

New PCI card with C-Media DDL chip: http://www.avsforum.com/avs-vb/showthread.php?s=&a... ge=20&pagenumber=1Currently only available via ebay apparantly:

If it has the same performance as Soundstorm remains to be seen. Reading the thread the EAX support is just as dodgy as it was on Soundstorm.

What chipsets did your USB and firewire drives have?thanks for the great review!

Anyone know how they did the memory benchmark with memtest86 3.2? I can't find any option for testing bandwidth.Thanks,
Bjorn

Well if it's any consolation, PCSTATS have updated thier site review of the MSI Neo4 Plat SLI (and will probably make two more updates to it)- now states 96Khz
- will modify DICE statement
- they are indicating that the sil3132 can do raid5, but I'm not sure that it can...
Wow Roomraider, that's quite the system you have there.

I admit this is slightly OT, but as I first got excited about the possible DD-encoding feature on the MSI-mobo and then let down by the obvious lack of it, I was happy to find these news:http://news.designtechnica.com/article6709.html
http://www.engadget.com/entry/1234000683034067/
I know many of us don't like the DRM/HDCP-features of HDMI, but HDMI certainly is the way to transmit high-definition, multichannel audio *without the need* to compress ie. encode to DD. And live content, such as games, would not probably have the copyprotection flags on, anyway. Of course, getting enough coverage for HDMI in both h/w and s/w will take time, but I bet this is the way it's ment to be played in the near future.
For example, think about combining this with s/w generated mc-audio and Intel HDA. No need for badly implemented codec/DAC in this model. Of this combined with discreete graphics card and the audio generated with the help of vector processing on the card.. I just hope Intel/Nvidia/ATI/whoever would start a strong enough, open standard to compete with EAX. Then Creative would either have to run, fast, or join their forces.
Meanwhile, because there is not much HDMI-support (except for the earlier, non- multichannel-high-def-audio-supported HDMI-standard, for mainly graphics) some solution providing DD-encoding to be sent over standard S/PDIF would still be very, very desired for many of us.
I end this thread-hijacking attempt here and apologize if being OT. Now back to our regular programming... :)
