Sorry guys, my wife is not feeling well right now and I didn't have a chance to work on the miner today.
Just to let you know.
No worries dude

So, what kind of timing/frequencies does everyone run around here?
I've got a rig with 6 RX470 4GB (2 Hynix, 2 Elpida and 2 Samsung).
On the hynix: 1375 strap and memory @ 2000
On the elpida: 1500 strap and memory @ 2000 (I think it can't go higher, Watttool just resets the memory to 2000 when I try something higher)
On the samsung: 1750 and memory @ 2000.
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.
