PC-3200LLPT or PC-3500C2

I'm debating over two sticks of Corsair XMS ram, the 3200 with low latency and the 3500. here's the specs

Corsair Platinum series 256mb pc3200
Specifications: $118
Speed 400 MHz
Organization 32M x 64
CAS Latency 2-2-2-6-T1

Corsair black ramsink 256mb pc3500
Specifications: $116
Speed 434MHz
Organization 32M x 64
CAS Latency 2-3-3-7-T1

I'm looking for good overclocking with a C1 p4 2.4, which is better? They are both from newegg.com
