I've tried pretty much everything to get it stable at 100x8.5 with no luck. I have an Abit Bx6 1.0, Iwill Sloket2, and a globalwin fdp32 for cooling (with arctic silver thermal paste). My ram is 64megs of CAS2 pc100 and 128megs of cas3 pc133. My os is windows 2000, filesystem ntfs. When I try 8.5x100 at 1.7 volts, it posts but doesn't start the OS. At 1.75-1.9 volts the operating system begins to start and I get a VXD error. Is this a Windows 2000 issue? I am not dual booting with windows98, so I haven't tested it on that Os
