Epox 4SDA+ SiS645 Socket 478 Motherboard

Epox 4SDA+ SiS645 Socket 478 Motherboard - PCSTATS
Abstract: Epox has always had an adventurous side as a company. That trait was evident in their recent AMD boards which gained so much attention.

Overclocking and Benchmarks

In the screen shot above you can set the memory frequency to either 1:1 which runs the ram at 100 MHz fsb, 3:4 which runs the ram at 133 MHz or 3:5 which has the ram running at 166 MHz.

The CPU FSB can be adjusted 1 MHz at a time from 100-200 MHz and there are a whole bunch of voltages that can be chosen. CPU voltages range from 1.75-1.85V, DDR voltages go from 2.5-3.2V and AGP can be adjusted from 1.5-1.8V. The two that stand out are the memory and AGP. It's obvious that Epox is trying to catch those Pentium 4 overclockers and since the Northwood P4's don't have a hard time hitting those high FSB, memory voltage helps stabilize things.

As for AGP voltage, again it's for stability purposes. Increasing the AGP voltage to 1.8V also allowed us to overclock our GeForce3 Ti500 10 MHz higher (then we ever could before) on the core!

We were pretty sure the maximum our Pentium 4 2 GHz (Williamette) would clock was around 2.2 GHz, however we were very pleasantly surprised by how high we could get it on the EP-4DSA+!

We were able to run the CPU at 2.3 GHz with no stability problems whatsoever, and with just air cooling and a vCore 1.85V. It's amazing that this board allowed us to overclock 50% higher then the others! Great job Epox!

SYSmark2001 uses real world applications concurrently as an accurate way to test the system by following patterns that reflect the way real users work. SYSmark2001's workloads accurately represent today's updated business usage model. The benchmark runs at a realistic execution speed, with think times between application interactions, in order to emulate a desktop user's interaction with the operating system and applications.

Higher numbers denote better performance.

1. Internet Content Creation - 4SDA+100 MHz 213
2 Internet Content Creation - 4SDA+ 115 MHz 231
3. Internet Content Creation - P4PA 100 MHz 213
4. Internet Content Creation - 4D845A 100 MHz 208
1 Office Productivity - 4SDA+ 100 MHz 149
2. Office Productivity - 4SDA+115 MHz 177
3. Office Productivity - P4PA 100 MHz 152
4. Office Productivity - 4D845A 100 MHz 131

The performance of the EP-4SDA+ is on par with the other Pentium 4 DDR boards which is pretty good. Overclocking seems to boost performance quite a bit, it's probably due to the 300 MHz CPU gain.
