tWTR 13-14
tRRD 5-8
tRD_WR 9-10

Also try Ras to Cas 5 and if all that doesn't work try 5-5-5-15 timings to see if that gets you higher clocks. If it doesn't it means you're probably chipset limited.

It seems that the DS3 is ignoring most of the settings in the SPD of the ram. I get pretty much the same sub-timings with my crap sticks (they're either elpida or powerchip.)
