these chips are weird, I've had them not work at a certain fsb when paired with a certain multiplier, and but both the multiplier and fsb work with other combos. Also my chip overclocked a lot more after burn in. check out my thread at [L=]http://forum.oc-forum.com[/L], it's under amd cpu, or do a search for dlt3c 1700 under the same username. I've had a trip, but right now i'm sitting at 210x12 @ 1.9v, and it won't take any voltages higher than 1.9v, even at lower speeds or anything.
