Would be nice to set your ram from bios settings to something lower than 1:1 ratio. Maybe they cant take the 375 bus speed. For start try to go 6-6-6-16 on the timmings and try 1:1 . If that works try to lower the timmings a bit. If that doest work try to underclock your ram speed at 5:4 ratio and keep timings at 5-5-5-15.
Good luck
