Overclocking the CPU

There's no doubt AMD has fine tuned its Athlon64 0.13 micron manufacturing process, but even with that said I didn't have much hope for overclocking with the Athlon64 3800+. Without the ability to raise the multiplier, we had to increase the motherboard frequency in order to overclock the chip.

Starting at 200 MHz we began to raise the clock speed slowly. Not surprisingly, at around 207 MHz the CPU started to become unstable and we had to raise the voltage to 1.55V. Continuing onwards, we ran into problems again at 212 MHz.

Raising the voltage to 1.6V solved that. In the end, we hit the wall at 214 MHz motherboard clock speed which equals 2.57 GHz CPU speed. Not bad considering the original Athlon64 3200+ on the same manufacturing process could only hit 2.4 GHz.

During testing we had to lower the memory divider from 1:1 to 5:4 when overclocking. I'm not sure what the problem was, but when the memory was running 1:1 it would blue screen randomly.

The Athlon64 3800+ performs quite a bit better than the older AMD offerings like the AthlonXP 3200+ or Athlon64 3200+. It looks like office based programs benefit from greatly from the integrated dual channel memory controller. Performance between nVIDIA's NF3-250Gb and VIA's K8T800 Pro chipsets is very close and a "winner" cannot be determined.
