Epox 9NPA+ Ultra: Overclocking and Stress Testing
Overclocking
| Front Side Bus Overclocking Testbed | |
| Epox 9NPA+ | |
| 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 SATA 8MB Cache |
| Maximum OC: (Standard Ratio) |
240x12 (Auto HT, 2-3-2-7, 1T, 2.9V) 2880MHz (+20%) |
| Maximum FSB: (Lower Ratio) |
302x9 (2718MHz) (Auto HT, 2.5-4-3-7, 2.9V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+51% Bus Overclock) |
The overclocking options finally pay off on the Epox 9NPA+ Ultra, as our Reference 4000+ reached a new stock overclock of 2880MHz (240x12), a 20% overclock of the stock 2.4GHz. The Epox also did well at lower multipliers, reaching a 302x9 speed, which is a 51% overclock of the 200 bus speed. This is still a bit slower than the 318 posted by the DFI, but it placed the Epox in 2nd place for bus speed overclock in this roundup.
Memory Stress Tests
Our memory stress test confirms the ability of the Epox 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.| 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 Epox 9NPA+ Ultra board required a 2T Command Rate with 4 DS DIMMs in two dual channels, as we have seen on other top-performing Socket 939 boards, but the memory did operate at DDR400 without any problems. We also checked memory performance with 4 DS DIMMs running a Rev. E AMD processor and found 2T Command Rate was still required with 4 DS DIMMs running with a Rev. E CPU.

oh...final system will have 4-5 HDs, standard DVD reader/writer along with (most likely) a 6800Ultra or a X800XL...Xenoterranos - Wednesday, July 6, 2005 - link
Anandtech did toy with a listening test a while back (I really don't remember much about it, other than the fact that they should have used Klipsch proMedia Ultra 5.1 speakers...)vijay333 - Wednesday, July 6, 2005 - link
Maybe I missed this info in the article somehow, but could you provide the minimum/recommended PSU wattages for the motherboards? esp the DFI and the Epox. I have a Antec 400W Smartpower PSU right now, but read a few posts on newegg that this might not be enough? Hope I don't need to upgrade this too along with the mobo, cpu and gpu...vijay333 - Wednesday, July 6, 2005 - link

I have a comment about audio -- a topic that most sites ignore.Shouldn't there be a blind listening test?
i mean cpu utilization is fairly useless. If i am listening to mp3s i care more about the quality than cpu utilization.

I stopped reading on page 4 upon discovering the round-up. No explanation needed...Wesley Fink - Wednesday, July 6, 2005 - link
g33k -The DFI was more a control to demonstrate SLI and Ultra performance were the same other than SLI video. Drivers have updated and we retested everything on the DFI as a sanity check. We ran benchmarks and not a full review, but it was hard to ignore the excellent performance.
There is also a comment in our Final Words that the MSI Ultra board should also be considered a winner, since the SLI version was a Gold Editors Choice in the SLI roundup, and the Ultra should perform the same.

Along the same logic though, I'm curious as to why you chose to review the DFI Ultra-D when you reviewed the SLI version of this board earlier as well?.g33k - Tuesday, July 5, 2005 - link
Jeez, read Wesley's comments, he just answered why he did not review, the MSI board. It was already reviewed in the SLI roundup.Wesley Fink - Tuesday, July 5, 2005 - link
"As you can see, none of the onboard audio solutions were quite as low in CPU utilization as the Creative SoundBlaster Live! Chip, which is used on the MSI K8N Neo4 SLI Platinum tested in the nForce4 SLI roundup."Since this is still nF4 we included components tested on all nForce4 boards. The Ultra version of the MSI, BTW, uses the Realtek ALC850 chipset and not the Sound Blaster Live!. The SB Live! is only used on the MSI SLI.
