Thanks for all the info guys.
I am banging my head against the wall right now, have gone through so so many configs, mining software versions and flavors, different controllers etc. literally everything I have been able to think of and even underclocked by 10% my Fury is consistently giving a 30% -40% error rate with 20% of them HW errors. At the suggested 328 freq I get 60%-70% errors. I can not at any freq get a hash rate above 1.2 (and that is fleeting , never lasting more than a minute or so) even clocked at 344 I get a hash rate around 900 khs (although it fluctuates wildly with readings showing from 6.8 MHS to 30 khs) on the poolside I never get above 1 mhs, ever, no matter what my config.
Adding the --nocheck-scrypt lowered my error rate from the 40%-50% range but still its too high to use.

About ready to RMA it. Any thoughts?
Did I just get a bad one?

Have you tried different pools?  I've found that with these Zeus chip devices you really have to find the right combo of pool + miner software.

Is your OS Windows?

This BFGMiner 4.2.2 https://litecointalk.org/index.php?topic=20477.0 as noted by jekv2 can work really great on some pools.  I can get 1,600 kh/s average on Litecoinpool (straight LTC) with my overvolted Fury.

Dmaxl's first windows cgminer build also works well for me: CGMiner v4.3.5.beta1release  I managed to get one Fury to 1,588 kh/s average on Litecoinpool so almost as fast as BFGMiner 4.2.2.  Cgminer 4.3.5 seems to be compatible with more pools though.  I'm running 1 Fury on CoinKING with Cgminer 4.3.5 beta 1.  I couldn't with BFGMiner 4.2.2.

I tried Dmaxl's second windows cgminer build -> CGMiner v4.3.5.beta2 release on CoinKING but switched back to the first release because it looks like I was getting a few more errors.  It might work better for you.

The options are set differently in BFGMiner 4.2.2 and CGMiner 4.3.5

CGMiner 4.3.5 --zeus-clock 328 --zeus-nocheck-golden --zeus-chips 6 --scan-serial //./COM4
BFGMiner 4.2.2 --zeus-cc 6 --zeus-clk 328 --zeus-rc 300 -S zeus:\\.\COM4

Edit: dmaxl's CGMiner v4.3.5.beta2 release might make it to 1,600 kh/s for me.  My 24 hr avg poolside is heading up.  1,591 kH/s right now.
