So far, this $65 board has faired pretty well against other H55 micro ATX motherboards that are about $20-$30 higher in price. The final test for this board is to see how it handles overclocking and voltage mods. We’ll be testing to see if we can break the 4GHz barrier on our Intel i7-860 2.8GHz processor. To do this, we will be increasing the base clock and doing some like CPU and RAM voltage/frequency mods to see how well this board handles moderate overclocking techniques.
We initially started manually adjusting the CPU base clock and voltages through the BIOS. After flashing the BIOS to v1.0 (5/19/2010), we started to work on increasing the base clock by 1-5MHz increments. After reaching over 210MHz, we began to see instability issues so we had to decrease the BCLK to around 202MHz before we saw more stability from the H55H-M. We were going to start increasing the CPU voltage, but we were already around 4GHz, which was our goal for the overclocking portion of this review.
See below for all of our BIOS settings and Cinebench screenshots detailing how we successfully overclocking the H55H-M to 4Ghz.
This screenshot was taken when we achieved a 4GHz overclock by manually adjusting the CPU settings in the BIOS.
