I´m building me a new AMD x2 rig with the A8R32 mobo from Asus and was thinking of buying the 3500LL memory. Does this memory work at 437 speed with 2-3-2-6 timings at default installation right out of the box or are they just guaranteed to work at these spec..must I overclock to obtain the 437mhz 2-3-2-6 speeds..
