It's kinda a copy or claymore but better in my perspective (more info & faster mh/s).

I used exact the same config for PhoenixMiner as I used for Claymore. I've set the mvddc, cvddc, cclock, memclock to a specific value for each card. I have 6x RX 580 8gb and i've set for every individual card a value.
Claymore was consuming 850W and a hashrate of 181mh/s.
I tried PhoenixMiner 2.9e (exact parameters) and it uses 1200W !!!! I didn't know it was doing that because I used teamviewer. So after like 4 minutes I checked my miner in the basement because the temperature of the cards also increased. And then I saw 1200W for a 1000W PSU..... I immediatly switched the power off.

Now I do have 2 questions:


1. How did it consume 350W more?
2. Did I badly damage my 1000W gold+ PSU?

Thanks

As for your question about damaging the PSU, probably not.  The wattage rating on a PSU is what the unit is expected to OUTPUT... in your case, 1000W.  However, it is not perfectly efficient, so draw from the wall will be higher.  If your PSU is gold rated (80% efficient), then at maximum capacity, it should be pulling about 1200W at the wall.  This isn't a good thing to do in practice, since it generates a lot of heat and leaves no headroom for the system to get any more power (which would cause instability / crashes), and efficiency decreases at higher loads which means more $$ for power.  But if you only ran like that for a few minutes, then you don't need to worry about damage.  1000W PSU is pretty borderline for 6 580's, but if it's working for you then great.

As I said before, try the 18.3.4 drivers (and make sure you enable compute mode in settings) and run PheonixMiner again with your voltage tweaks.
