1 of 6 RX570's showing up as orange and not mining xmr

Hi All. So glad I found HiveOS, but I have a minor issue of one of my 6 RX570’s is showing up but not mining. It shows up as highlighted orange on the hiveos farm website monitor interface. temperature on it is low and no hashrates

I think it may be due to it having different memory - 4 of the cards have Hynix, 1 has elipida (I think this is the one not mining) and the other has Samsung.

I am also getting pretty low cryptonite hash rates (just under 600) where on windows 10 I was getting around 650 before the drivers got broken.

Furthermore, my hashes are showing on the miner and pool, but not on the web monitor.

I am not a very high level user, and need some help please.

You write strange things for me

RX 570 hashrates at cryptonight algo are
cryptonightv7 - 750-960 depends of memory vendor and other things
cryptonight-heavy 660-1100 depends of memory capacity, memory vendor and other things

Basically my primary concern is that one of my cards wont mine should I change the DMP for that card? (my low hashrates are secondary issue). Below are my GPU details (note GPU 4 is not hashing).

GPUO - SK Hynix H5GC4H24AJR, 113-D0003400_100:
54° 52%
583

GPU1 - SK Hynix H5GC4H24AJR, 115-C940PI0-100:
51° 52%
637

GPU2 - SK Hynix H5GC4H24AJR, 113-D0003400_100:
48° 52%
557

GPU3 - SK Hynix H5GC4H24AJR, 115-C940PI0-100:
57° 52%
637

GPU4 - Elpida EDW4032BABG, 113-V34121-X3:
32° 52%

GPU5 - Samsung K4G41325FE, MS-V34113-F4:
34° 52%
628

Overclock settings:
CORE 1100 1100 1100 1100 1100 1100
DPM 1 1 1 1 1 1
V 900 900 900 900 900 900
MEM 2100 2100 2100 2100 2100 2100
FAN 55 55 55 55 55 55

Looks like the undervolt/overclock was preventing it from working.

new working oc settings:
CORE 1100 1100 1100 1100 1050 1100 DPM 1 1 1 1 2 1 V 900 900 900 900 975 900 MEM 2100 2100 2100 2100 2020 2100 FAN 55 55 55 55 55 55

any advice on getting the 750 - 790 MoneroV7 hashrate - I am getting:
47° 52%
583
46° 52%
639
43° 52%
556
49° 52%
638
37° 52%

34° 52%
628

Cryptonight algo - is not Ethash
Cryptonight algo except memory also needs GPU core overclock (or at minimum without downclock) and GPU core in its turn needs power to work. If you deprive this card, you either get a low hashrate or unstable work. Another story - miner and tunning for best results.

See this recommenations for tunning core/memory clock - http://forum.hiveos.farm/discussion/comment/4414/#Comment_4414
