Soltek incorporates a handy little feature in the BIOS of the 75DRV5. This is called Redstorm Overclocking and when enabled it increases the CPU frequency automatically until it reaches an unstable level, where it will then reboot your system to the last stable speed obtained. This is very handy for those that are new to overclocking and do not want to fiddle with the options on their own.
You are also able to adjust the clock frequency manually from 100MHz up to 200MHz in 1MHz increments. VCore adjustments are also available in the BIOS, with settings up to 1.85V in 0.025V increments. That is about where it ends though. Multiplier, DIMM voltage and AGP voltage all have to be adjusted via DIP switches and jumpers located on the motherboard. While this is better than having nothing at all, these options come standard in the BIOS of most newer boards since it is much more convenient then having to delve into your case every time you want to overclock.
The maximum speed I could obtain with the 75DRV5 was 1.725GHz (150MHz x 11.5), with a 1.85V core voltage. This is less than 200MHz above the default speed and although it is a fairly decent overclock, I must say I was expecting a bit more. Maybe the KT333 chipset is reaching its limits? Or maybe it's just the Soltek board? Whatever the case, due to the fact that not all overclocking options are included in the BIOS, and that the board was not stable with an FSB higher than 150MHz, I cannot recommend this board to those of you that are planning on obtaining extremely high speeds.
