FSB+ or lower timings?

I am running a 3.4 Prescott at 266x14 (3.7) on A-bit Fatal1ty and the memory runs at 355. I'm using Mushkin 5300 so I think it is running at 710. The timings are 4-4-4-11 and I can't lower them even with increased voltage.

I can run them at 3-3-3-8 with a FSB of 216x17 though.

Which setup will give the better performance ?

Thanks for info!

Sorry to state the obvious, but why not test it? You'll get the best answer by testing your particular system.

As Sucka stated the best way to see what provides the best perfrormance is to test it yourself.
