I've an X2 3800+ that runs @ 2,8Ghz vCore default with async mem (ddr @ 400) + DFI LanParty UT NF-4 Ultra-D (last official DFI bios) + G.Skill 4800FF (2x512). There're stability problem if I want to use my 4800 @ DDR 550 or @ DDR 600. I don't found the perfect stability with my hw; when i try to set my 4800FF to DDR 550 (275x10) or @ DDR 600 (300x9). I've problem with the boot or instability after the loginf of WinXP Pro (SP2).

I've read your guide but I've the same problem.
Please G.S Technician or someone help me to solve this problem!


Thanks
