Hi there,
I have 4 GPUS (1x RX 570, 3x RX 580). I'm using AMD Radeon drivers (non-whql-win10-64bit-radeon-software-crimson-relive-17.10.2-oct23).
Do you recommend me to update it to the last version (20.4.x) or don't touch anything?
I've got around 124MH/s. Is it right or I can obtain more MH/s Huh

Thanks in advance!!!!

hi
On the drivers of the new version, you will only lose speed. The latest version of drivers is needed for new 5700 and higher cards, as they simply do not work on old drivers. For video cards 470-580, the optimal drivers are 19.7.5. I have two rigs and both used to work on drivers version 19.7.5, but then I purchased 5700 cards and inserted them into one of the rigs after which I had to update the drivers to version 20.4.2 and what did i see? i saw is that the speed of 580 cards decreased by 300 hashes from each video card (from 34.6 to 34.3 megahashes)

If you use 19.7.5 for a long time and satisfied it doesn't mean that the said version is somehow "optimal"
I've stopped using my default 18.6.1 version some time ago, which worked fine for a few years.
I'd suggest 19.12.2 or 20.4.2

Also what is this 34.6 for Polaris? looks too much

Driver version 18.6.1 as well as 19.7.5 for the 580 are very good, but if you use the latest version of the phoenix miner, then when using 18.6.1, some functions are not supported, for example, you cannot set the fan speed, on 19.7.5 there is support for fan speed
As for the speed, this is quite realistic and even higher, you need to overclock the memory to 2250-2300, select the timings, set the bmp parameter to 20-25, or use a special program and raise the core frequency to 1240-1260. Many have already forgotten or do not even know that the 19.7.5 drivers give a slightly higher mining speed than the new ones for the 470-590 series
