My 7970 with Hynix Mem is running about 313H/s but about 225W. Its a modified BIOS but no custom straps.

What do you mean "a modified BIOS but no custom straps."?

I just grabbed a BIOS that would allow me to OC the card past the default max, which was something like 1525MHz on the Memclock. Now I can OC up to 2000MHz on the memclock. I believe this is the BIOS I grabbed for it: https://www.techpowerup.com/vgabios/123523/sapphire-hd7970-3072-120628

It's a Sapphire 7970 non-ghz edition. But I think I flashed it with the Vapor-X bios. Its been running solid for about a month now.

It seems that the memory strip mod for the ZEC mining is not so necessary. For ETH, it is more important.
