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?
I had a similar problem. I had to go way beyond the advised warranty voltage to do 3-3-3-10. 2.45v was needed. It's a Kingston problem. I had Kingston PC9600 dimms who did PC6400@3-3-3-10 in a Abit IX38 QuadGT, on the Maximus i needed 2.45v. Now i have Team Xtreem PC6400 C3. They do DDR800 @ 3-3-3-8 @ 2.32v. I can even do DDR1100 @ 4-4-4-12 @ 2.35v with these sticks.....
