I have never heard of anyone blowing a VRM by running at 325. Gentarkin runs his like that and so do many others. If he's not THE Titan veteran, I dont know who would be 
Plus if you notice the current on the dies > 40A - the VRMs are only rated for 40A - meaning he's killing the VRMs to boost up the hashrate. I'd pass and I think other Titan veterans would as well.
Sure - makes sense.
The Ericsson VRMs on the Titans are rated for 40A. Run them at 43A 24/7 and see where it gets you. I stand by what I said before...
That said, I hope you get big bucks for your rig and set the marketplace.
