Gigabyte Z77-D3H (Z77) Motherboard Review
Andy Ruffell / 12 years ago
After running our stock tests, it was time to see how far the processor could be pushed. We started by pushing the multiplier to 46x with a voltage of 1.35V. While it booted into Windows, it immediately crashed after a few minutes of Prime95 which was used to test stability.
We upped the voltage to 1.38V and continued to boot back into Windows and to run Prime95 again. This time, things ran much more smoothly and gave us some ambition to push things further. A 47x multiplier was next but no matter what settings were tweaked or what voltages were thrown at it, the board refused to run stable.
Assuming that the 46x multiplier was the limit, we could now focus our energy into the BCLK to see if anything can be squeezed from there, but alas, it couldn’t. Even .1MHz was not going to happen on this board, and we were faced with a final overclock of 46×100 giving us 4.64GHz.
The final recorded voltage was at 1.38V and at 4.64GHz, it’s quite an achievement for a board that is aimed at the value segment of the market.
Now that the overclock is set into place, we can take a look at how this board performs at both stock, and 4.6GHz and how it compares to the competition.
