just bought some ddr it's 1gb samsung ucccx2 rated at pc3200 but the guy i bought them from ran through memetest at 255 w/ 3-4-4-9 timings at 2.65 volts. i ran it through memtest and didn't get errors for over 6 hrs but it won't booot windows at those speeds i'm running and opty144 @3ghz w/ 1.5v . these are my memory settings can any one help tweak the memory settings or did i just get some bum ram.
