Setup notes
We're comparing the 6GB Crucial's performance against a 3GB Qimonda set that runs at exactly the same timings and speed but is comprised of three 1GB modules, making 3GB in total (well, 3GiB, but whose counting?)
The Intel Smackover X58 board, DX58S0, is limited to a 2:8 ratio when running a 133MHz reference clock on the non-Extreme processor. In plain English, this means that DDR3-1,066MHz is the fastest supported speed without raising the CPU's clock.
Unlike previous memory reviews, the gaming benchmarks use high-details settings. We see little point in highlighting how one set of memory is four per cent faster at 800x600 when it has no practical relevance to the usual games-playing experience. Rather, we're looking at 1,280x1,024 with vhq settings. Far Cry 2 makes an appearance for the first time, too.
