RAM Trilemma

I Recently bought 2×512MB of Corsair hoping that it would run at 2,0-2-2-10 on 400MHz in DC, but no way, even at 2-3-3-10 there are not prime stable.
So now my retailer has agreed to a refund and I'm in a trilemma which RAM to buy, it should run at 200FSB at 2,0-2-2-10 ( Dual Chanell), at 217FSB ( 433) also 2-2-2-10 ( Dual chanell), the ones between i have to choose are:
Kingston Hyper X 434Mhz (3500)
Corsair Twinx CMX 3200C2 ( 400)
Kingmax Hardcore 500 Overclockers choice (or maybe the regular ones where's the differnce?) :confused:

217 fsb @ 2-2-2-10 will likely have to be bh-5/bh-6, i think the hyperx has the best chance though.

and how do I recognise a BH-5 or BH-6 chip?
