We didn't have much luck at overclocking with this particular configuration, and were only able to coax this P4 chip into 1.77GHz post, and 1.71GHz boot. 1.71Ghz wasn't too bad, but not stable enough for Sysmark 2001 apparently - the benchmark froze part way through. Given the relatively minor increase in clock speed there isn't much in including those results here, so will just concentrate on the default speed results.

The Epox 4B2A does come with a very well equipped BIOS for the overclocker with a good deal of time on their hands to tweak around in however. In any case, lets move on to our first and most used benchmark, Sisoft's Sandra 2001SE:

When placed head to head with a comparable system using RDRAM the i845 solutions have proven themselves no quite as adept. Record setting performance this isn't, but among i845 solutions it will be interesting to see which motherboards prove themselves better than the rest. Compared to a 1.7GHz socket 423 P4 the memory bandwidth benchmarks illustrate the largest differences between i850 RDRAM and i845 SDRAM mainboard solutions.
