With DDR2 voltage options a bit low for our taste and basic voltage settings, we opted to test the overclocking waters with the M2A-VM HDMI, but didn't aim our sights very high. For starters, we dropped the CPU multiplier to 5X and lowered the DDR2 to 400MHz and started raising the HT frequency in a quest for the highest stable speed. In the end, we topped out at 232MHz. However, once we set our multiplier to x11, the board wouldn't boot into Windows. So, instead, we opted to find the highest we could go with a stock multiplier and managed to take our Athlon X2 5200+ from a stock speed of 2.6GHz up to 2.92GHz with an HT frequency of 225MHz.
