Asus P7H55-M review

Can you get the most from Clarkdale with such a reasonably priced motherboard?

TODO alt text

We tested the P7H55-M with an Intel i7-870, a meaty Radeon graphics card and two sticks of Corsair memory running at 1,333MHz (although it isn't, true memory speed is arcane knowledge).

Here we've pitched the new bug against a Gigabtye H55M-UD2H – not quite as feature-rich perhaps, but using the same Intel chipset and aimed at the same buyer and sells for about the same, too. Both boards were run without any overclocking (not as easy as it sounds; they were quite keen).

As you might expect, it's a close-run thing. The Asus has a slim but clear lead in the application benchmarks. Why the memory bandwidths differ is a bit of a mystery. An erroneous timing setting perhaps?
