To check the AMD Athlon 64 X4600+ and the motherboard, we used Lavasys Everest Ultimate Edition 2006. We were able to extract the following information about the system:

For all tests, we used Mushkin 2x512MB, DDR2 800 at CL5 rated memory modules.

Below is more information on the north/south bridge chipsets.

We looked for a newer BIOS with Foxconn's LiveUpdate software. Our board had version P19, and while the software didn't find any new firmware, we manually updated it to version P23 revision, which was the latest available at the Foxconn website.

Finally, we take a look at the default operating specs of the Athlon 64 X2 4600+ on our Foxconn C51XEM2AA motherboard, using CPU-Z.

As we can see, the default voltage for the CPU is 1.248v, much lower than on the ASUS W2N32 WS Pro motherboard (1.344 V).
