Could not boot into any OS more modern than NT4 with this chip on either my GA-5AX or VA-503+ for some reason. As such, older CPU-Z had to be used, and even with 1.27 the chip clearly suffered from some serious detection problems. CPU-Z 1.27 was the only CPU detection utility to get the speed right, though. I ended up having to use a 150 MHz validation from current CPU-Z from another chip in order to submit this result.
