Overclocking

At first, I could not successfully get any overclocking done on the Biostar Racing Z370GT6. While it would seem to be at the target multiplier of 48, as soon as load was applied, it would shoot down to 43 and stay there until CPU load went back to zero. Fortunately, after communicating this issue to Biostar, a fresh bios update completely cleared up that issue. Post update, the board not only achieved my initial goal of 4.8 GHz, but exceeded it, achieving 4.9 GHz at only 125 watts of power draw. Temperatures between stock clocks and overclocked were also virtually identical.

I had very different, but far more explainable RAM issues. While the board booted perfectly at the standard 2133 MHz settings, attempting to use XMP profiles with the G.Skill 3866 kit caused a failure to post, and manually tweaking the voltage and speed settings mostly led to the same results. Plugging in a different kit, the T-Force Delta RGB, I was able to easily select XMP profile one and boot right into Windows. The two 8 GB sticks ran at their max rated speed of 3000 MHz with no fiddling required. Thus, I would recommend choosing your RAM kit carefully if you want to do any overclocking with it on this board.


Thankfully, the Biostar Racing Z370GT6 has a POST code display and a clear CMOS jumper, which are both invaluable tools for troubleshooting.
