Manually set the memory to 667 Mhz, the voltage to 1.8V-1.9V and the timings to 5-5-5-15 or whatever the Kensingtom RAM requires at 667 MHz. If that doesn't work, then the modules are too different to work together.

no matter what i do they don't work, i changed all settings to manual and tried each set with those settings they worked, but once i put the sets together the system won't even boot, won't even go to bios, to change settigns again i have to remove a set so i can go to bios(scren won't come on ither)

If you have OCZ kit OCZ2P8004GK, then it's qualified for 2 modules only (see the QVL for more info) at http://tw.asus.com/886/download/pr [...] 272_10.pdf. 4 modules of Kingston ValueRam (if they are identical) should work.

Memory modules like the G.Skill PI Black or similar modules that require 1.8V at 800 Mhz and 4-4-4-12 timings usually are less problematic when using 4 modules.
