DDR2-800 vs. DDR3-1333. Does DDR3-1333 Make Sense?

@ 2008/01/17
We're going to compare performance of two processors in combination with different memory modules: standard DDR2-800 and higher-clocked DDR3-1333. The Core 2 Extreme QX9650 processor (1333 MHz FSB) will be tested with one and the same motherboard that supports both memory types (Foxconn X38A). And the Core 2 Extreme QX9770 processor (1600 MHz FSB) will be tried with two motherboards, different in supported memory types.

how much do you pay to go lower?

DDR3 1333 9-9-9-24 doesn't make any sense, no.

faster memory yields 1% performance gain on one of the fastest processors with the 1333 MHz FSB, while the only processor for the 1600 MHz bus gains 2% from it
DDR2-800 2gb kit can be had for €40 !
