cjlittle, i have to disagree with you big time, my kingston hyperx does just fine,
But of course scooter, you are runniing a 2400 cpu so your ram is ok . your buss is slower. try that same ram with the 2800 barton and you will see what hes talking about.
Hyperx is the only chips for sure but with kingston he would need the 3200 not the 2700
I agree 4000 would be overkill. good timings are everything 8,3,3,3 with 1.1 fsb wold equate to his 3,3,3,5 which I recomended he up to 3,3,3,7 (or 8 )
