Asus A8N-SLI Deluxe: Overclocking and Stress Testing
| Front Side Bus Overclocking Testbed | |
| Asus A8N-SLI Deluxe | |
| Processor: | Athlon 64 4000+ (2.4GHz, 1MB Cache) |
| CPU Voltage: | 1.5375V (default 1.50V) |
| Cooling: | Thermaltake Silent Boost K8 Heat sink/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) |
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) |
Asus has been the overclocking leader in many of our recent Intel processor roundups, so it was certainly a disappointment that the Asus turned out to be a below-average overclocker in the SLI roundup. The highest CPU speed that we could reach with stability was 255, but performance at the stock 12 multiplier of our 4000+ was a respectable 234. With two of the boards in the SLI roundup going well above 300 in the same configuration, this was hardly impressive overclocking.
Memory Stress Test Results:
Memory stress tests look at the ability of the Asus A8N-SLI to operate at the officially supported memory frequency at the best performing memory timings that our standard OCZ PC3200 Platinum Rev. 2 will support. Memory stress testing was conducted by running 1:1 at DDR400 with 2 DIMM slots operating in Dual-Channel mode.| 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 |
The Asus SLI was completely stable with 2 DDR modules in Dual-Channel at the settings of 2-2-2-7 at default voltage. This matches the best timings that all of the SLI motherboards in this roundup were able to achieve.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DDR modules on a motherboard.
| 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 |
The Asus K8N-SLI was completely stable at 2-2-2-7 memory timings. We did have to lower the Command Rate to 2T, but this is a function of the on-chip Athlon 64 memory controller. It is rumored that upcoming Rev. E chips will have an updated memory controller capable of driving 4 DIMMs at 1T command rate, which would definitely improve memory performance when running 4 DIMMs.

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)
(+59% Bus Overclock)

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... :)
