That rig averages 4200Kh/s on XMR, but I feel it could do better. I do not have a lot of time to do tests though

. Also since GG, Wattool and GPUz all have their own way to "assign" cards it's kind of a nightmare figuring out which is which on that rig, lol.
All cores run at 1100MHz and I'm bios undervolted at -137.5mv.
Trick I use is to set different mhz in bios for each card, so in my rig left to right, i have 1141, 1142, 1143, etc.
root@rig14:/home/dallas# clocks
1: 2012Mhz * # GPU 0
7: 1142Mhz *
1: 2013Mhz * # GPU 1
7: 1143Mhz *
1: 2006Mhz * # GPU 2
7: 1146Mhz *
1: 2015Mhz * # GPU 3
7: 1145Mhz *
1: 2014Mhz * # GPU 4
7: 1144Mhz *
1: 2011Mhz * # GPU 5
7: 1141Mhz *
Then I know GPU #2 reported above is the furthest card on the right, GPU #5 is furthest left
