Anyone run hC 6/7 with 64 bit severs?

I am having some issues with HC timing out and I had mentioned that it might be because it was 64 bit. Then as soon as I mentioned that they jumped on that as a reason.

However AMD 64's have a legacy 32 bit mode for 32 bit applications.

So anyone running it without any issues?
Thanks
