Gigabyte K8NXP-SLI: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| Gigabyte K8NXP-SLI | |
| 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: | OCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips) |
| Hard Drive: | Seagate 120GB 7200RPM SATA 8MB Cache |
| Maximum OC: (Standard Ratio) |
230x12 (4X HT, 2.5-3-2-7, 1T, 2.8V) 2760MHz (+15%) |
| Maximum FSB: (Lower Ratio) |
230x12 (2760MHz) (4X HT, 2.5-3-2-7, 2.8V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+15% Bus Overclock) |
After the excellent overclocking results that we found in our pre-production review of the K8NXP-SLI, we really expected the Gigabyte SLI to be near the top of our overclocking charts. However, something has happened along the way from pre-production to production because our production board could only reach a very disappointing 230 CPU speed regardless of the multiplier selected. This is in stark contrast to the 284 that we easily reached on the pre-production board.
We recently met with Gigabyte to discuss this issue and Gigabyte has assured us that they will make updates to get overclocking back to the levels which we saw in our earlier review. For now, we can only say that we have no idea what you will actually find in the overclocking capabilities of a K8NXP-SLI that you might buy. It could be stellar, like the pre-production board that we tested, or mediocre, like the last board that we tested. We have evidence to support either conclusion.
Memory Stress Test Results:
Our memory stress tests measure the ability of the K8NXP-SLI 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 2.6 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 Gigabyte 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.

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,

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... :)
