All things considered, the only real thing to be limiting the overclocks you can attain on these motherboards is a chip's thirst for voltage. Though we had a fair bit of luck (topping the chip out at a modest 238MHz), we found that without the ability to pump up the chip's voltage, we found ourselves unable to press on any further - the same thing, of course, proved true for the memory. With a paltry 1.8V, we found it impossible to even hit the bare-bones 5-5-5-15 timings of the Super Talent memory at DDR2-800. Ouch.
That being said, this motherboard certainly won't be the darling of your overclocking escapades, but then again, what had you been expecting? What we can tell you is that it will provide a snappy and damn strong running base for your next office rig, or miniature gaming machine. You've just got to watch out for all the heat some of these chips can put out in those cases.
