Overclockers New Zealand has updated their DDR RAM Guide

Back in the early days of PC-2700, we had Samsung CTL-CB3, which was an incredible overclocker. It was used on practically all of the high-end modules. In the PC-3200 age, the WinBond BH-5 chip seems to be the next CTL-CB3. (Corsair are using this chip, hand picked, for their XMS-3200 module)

>From the pictures above, we can see that A-Data also uses the WinBond >HB-5 chips on their PC-3200 range. From the datasheet, the HB-5 is
