Lunga Chung: One other question I had about AMT.

Do I still keep my cards with the modded timings from Polaris?

I've seen some YouTube Videos that say you can restore the cards original vbios since AMT takes care of on the fly memory timings / straps... I suppose this is a manual effort though right? So I probably should just keep my modded vbios.

UPDATE:
I kept my cards with the timings from Polaris one click and set the REF setting to 90 like you said and let it rip!!

Total mh/s is between 257-258 which is 2 more than Claymore!!!

It is rare, but early on in the command line I was seeing blue gpu lines with a really low mh/s because one to three cards were at 0.000 mh/s, but then they recovered.... Is this something that will keep happening? I haven't seen it happen since, but have only been monitoring for 10 minutes. If it does keep happening, do I leave it as is or would you recommend I feed these cards an extra mV?

I am currently running:
1170 / 850
2150 / 850

I am thinking upping to 2200 with Phoenix Miner will make a difference and possibly take me up another 2 mh/s, unlike with Claymore.
