Not yet but will do tonight after work It used to boot with the DS3 at default 1.8v though.Nelly said:Indeed quite a few people are using the G.Skill 2GB DDR2 HZ PC2-6400 Kits on numerous forums. Infact it should boot at the default 1.8v because it did for me when I owned the QuadGT & HZ's. Have you adjusted the voltage to the reccomended spec 2.1v?
