Notes

There is usually little reason to comment in this section, but with the tested 0805 BIOS, the Asus board does not behave as expected.

The MSI and Gigabyte boards, used as comparisons, run at an all-core 4.7GHz and turbo to 5GHz correctly. The Asus, on the other hand, begins running at that 4.7GHz all-core but drops to 4.1GHz after a few minutes. There is no good reason for this because under-load temperature doesn't exceed 55C.

One can get around this by activating XMP memory settings and also running Multicore Enhancement in the BIOS. Doing so, though, increases the all-core speed to 4.8GHz, thus placing the board higher than either of the aforementioned two.

The only way around this is to input the per-core speeds manually, as shown on the previous page's first BIOS screenshot. We shouldn't have to do this; auto ought to work per Intel's specifications, so bear this in mind when setting up your own processor. The following results represent an apples-to-apples comparison, with an all-core 4.7GHz and turbo at 5GHz.
