OCZ DDR Booster Diagnostic Device
 

"The OCZ DDR Booster Diagnostic Device is a very unique product that draws additional power from the power supply. The end result is increased memory voltage. There is no modding required, just pop it into a memory slot along with DDR1 memory and you're ready. Anyone who is into overclocking will adore this product. With a compatible motherboard and this product, memory voltages over 4 volts are possible. Insane? Yes! Watch the Video to find out more..." ~3dGameMan.com
