Testing notes

Keeping parity with the other setups, a Radeon HD 6950 2GB card is the sole display for this round of benchmarking; the IGP's switched off in the BIOS. We'll discuss its performance separately.

Eagle-eyed readers may have noticed that the Turbo Boost frequencies shown in the BIOS shot on the previous page do not tally up with Intel's. The board would run a single multiplier across all cores, rather than the stepped pattern mandated by the CPU's spec. sheet. We changed the chip out to a full-retail Core i5 2500 with no success. Flashing the BIOS down from F4d to F4 didn't help.

However, contacting Gigabyte we learned that a single multiplier across all cores is actually a feature when running with DDR3-1,600 memory. The default multiplier is 37x, and the 2500K chip will, under load, run at this speed all the time.

As such, to keep parity with older boards - ASUS has since implemented the same-multiplier feature - the Gigabyte board has been tested with the multiplier maximised to 34x (all-core load). This means that light-load performance will suffer a touch - as the multiplier is limited. We could have chosen a multiplier of 37x for all cores, of course, but that would have been unfair on boards tested a few months' ago and included in this comparison.
