Hi,

Thanks Claymore for v9.8 - keep up the good work  

@ H311m4n
I see you are running lots of rigs and have good hashrates (29MHs) from undervolted 4G RX 470's?
I came acrross this thread after upgrading to Claymore v9.8 17.7.2 drivers and finding WattTool doesn't work any more.
There is a new AMD GPU Tool here http://elsonsmith.com/amd-gpu-tool/ which has a developer that is not AWOL unlike WattTool.
I wonder if there is milleage in getting this tool updated to work with the new AMD drivers?

I have a rig with 6 x RX 470 4GB (4 x Sapphire Nitro and 2 x MSI Armor)
I am getting about 25MH for each card (Dual Decred) undervolted & stable.

Core 1000 @ 850mv
Mem 2000 @ 850mv
The whole rig pulls ~840w at the wall @ 150MH ETH / 2650 Dec

I will just talk about the Hynix Saphire Nitro's now...

My bios is strapped with only the 1500MHz copied to higher frequencies.
I have seen some bios upgrades which suggest using the GAME OC BIOS,

Copy Timings
1500 --> 1750 and 2000
1425 --> 1625
1375 --> 1425 and 1500

TDP increase to 100

I tried Core 1050 & MEM 2070 with my current modded bios and the card didn't go above 25MH/s.

What settings (Core, Mem, mV) do you use to get ~29MH/s on the Nitro's and do you suggest I should re-flash my bios using the above settings?

Cheers Mate,
SG
