I don't see a liberty 520 listed at newegg, but whether it's the 500 or the 620 it should be fine, yet that behavior looks like a PSU problem to me.

I see those PSUs have modular cables. Is the extra 4 pin section on the ATX power connector detachable on the PSU end? If so, you might want to check that it is connected properly. My P5W DH will run without the extra 4 power pins connected, but it behaves in a similar way to what you are seeing. My PC2-6400 RAM would test good running at DDR2-667 without those pins connected, but wouldn't work at its rated speed.

You just need to change the divider for the DRAM speed when you get everything working. It's normal for it to be set at PC2-5300 until you do.
