For the #overclockingbuildoff I will be pushing the legendary AMD Am5x86 processor to 160MHz on my ECS UM4981 VESA local bus system. This board doesn't officially support the CPU, so it required a bit of extra work to get it going to its full potential. Despite it's confusing name, the Am5x86 is not a Pentium Overdrive competitor, but rather a true 486 processor with an already incredibly high default clock of 133MHz.

Please be sure to check out the other #overclockingbuildoff videos that will be released by others over the coming days and weeks. I'm sure there will be some very interesting reveals!
