Which would be faster?

[mhowie]

I have an AMD Athlon 64 X2 5000+ Black Edition, stock speed 2600 MHz (200 x 13 multiplier). I also have 2GB TWIN2X2048-6400C4DHX Corsair RAM.

 

If I slightly overclock, I seem to be able to run at the stock CPU voltage and maintain system stability at both 14x and 14.5x multipliers (2800MHz and 2900 MHz respectively). I find, however, using CPU-Z that my RAM is running at 800MHz at the "slower" 14x multiplier and it runs at 725MHz with the 14.5 multiplier).

 

My question: will the system be "faster" by increasing the CPU speed 3.5% (2.8GHz to 2.9GHz) while suffering by 10%+ on the RAM MHz speed, or should I sacrifice the CPU bump and take advantage of the RAM running at the full DDR2 PC6400 rating?

 

I don't know if there is a 1:1 correlation between increasing CPU speed and RAM speed for overall system speed calculations.

 

Thoughts?

 

Thanks,
