I can not get 3-3-3-10. Kingston6400, KHX6400D2ULK2/2G these are kits of (2x1G), I now have 2 kits 4G total. One time I was able to boot up at these settings, I beleve it's when I had one kit installed only.

Kingston specs say these kits are tested to run @ 800Mhz 3-3-3-10 @ 2.3-2.35v. Spd jedec say 5-5-5-15 @ 1.8 I set my dram v to 2.35, manualy try 3-3-3-10 wont boot up, also tried Comand rate 2t and trans booster disabled, relax level 0.

With everything on auto she will boot up 5-5-5-15 @ 1.97, can even manualy set timings at 4-4-4-12 @ 1.97 but no-go on the 3's.

What can I change?
