6 x AMD RADEON 470 Rig - Suggestions to increase hash rate for XMR mining

[KK120]

Greetings to everyone,

I have since a couple of weeks a 6 X AMD Radeon 470 rig in operation with XMR-STACK-AMD mining software. The average hash rate is around 3.55 KH/s with the following settings in wattman:

GPU 1210Mhz
Mem 1750Mhz
Vot Auto
Fan 640-2600RPM
Temp 70 max

Is there a "safe" way to increase the KH/s rate with these cards from wattman or I need to flash new firmware etc?

Thanks!

To Unleashed the AMD's RX 470/480 570/580, you need to Mod the bios according to their memory types, below are tutorials threads

after modding, you can play with your clocks

Thanks for the quick response, much appreciated; it will be a busy weekend modding 6 cards

A quick question, regarding hash rates.
Is it normal to have this kind of fluctuation (from 2.5KH/s-6Kh/s) in the hash rates with xmr-stak?

These are pool stats, but I'm noticing also that the a similar drop is happening in the rig itself
