Brief:
If you ask an overclocker "Best memory chips ever?" you will most probably get the reply "Winbond BH5". Unfortunately Winbond stopped production some time in 2003 and supply of these chips was running dry pretty fast. Now Winbond is back with their BH5 UTT and OCZ has built the PC-3500 Gold Gamer Extreme modules with it. The modules run at aggressive timings of 2-2-2-5 and offer a lifetime warranty for up to 3.1V memory voltage.
