Epox motherboards generally overclock quite well, but
seeing as the EP-AF550G is a budget board we're not sure what to expect
this time around. Before the overclocking began, the AMD Athlon64 X2 5000+ processor was set to use a 8x multiplier, and the Corsair Twin2X2048-6400C3 memory to run in DDR2-533 MHz mode. This way neither component will hold the Epox AF550G from reaching its best.
Starting at 200 MHz the Epox EP-AF550G motherboard clock
speed was increased in 5 MHz increments. There was absolutely no need to adjust the CPU, chipset or memory voltage during any of our testing. Epox's EP-AF550G hit the motherboard's top speed of 250 MHz with ease, but that is where our tests also had to stop. It's worthwhile to remember that the Epox EP-AF550G is aimed at the entry level market, and is not designed for overclockers.
We would have liked to see higher motherboard clock speed options.... but for what the Epox's EP-AF550G offers we are satisfied.
Inside the Epox BIOS:
There are certainly lots of DDR2 memory timing adjustments to choose from, if
you're a tweaker you'll no doubt familiarize yourself with all these
The motherboard frequency can be adjusted between 200-250 MHz
in 1 MHz increments. The integrated GeForce 6100 core clock speed can
be increased between 1-100%. There are CPU clock multiplier adjustments. Maximum
CPU voltage is 0.15V above stock, chipset goes up by 0.3V, and memory by 0.7V.
Prelude to Benchmarks
