well you have better quality memory than I am using, I have Seitec DDR400, which is pretty generic, SPD timings are 8,4,4,3@400mhz, however and this is a very BIG however, I have found this memory to be much better than some of the more expensive stuff and I currently have it running at 6,2,2,2.5@400mhz with 100% stability, at 450mhz I can use 6,3,3,2.5 with out any instability.
check your memory timings, maybe you might have to relax them a bit to reach 400mhz.
I haven't used kinston in awhile so I'm not sure of the quality of late, but they used to be pretty good.
