I had these problems with DDR2 stuff in the core2 generation of processors, with the 3 and 4 series chipsets (P45, H3x, etc). I don't recall the specific Ballistix, but it was supposedly faster (higher clock rate and lower CAS timing) than the 'standard' ram for those chips. It failed erratically, after a year+ of stable running at the standard speeds, but in two different cases (different systems, boards, and memory) it would pass a 24 hour memtest even when running at 'overclock' rates (I test at conservative overclock speeds as well as normal, then run at stock speeds, presuming this gives me good margins). -- john r pierce 37N 122W somewhere on the middle of the left coast
