Hi guys,

i'm trying to underclock GPU core to lowering electricity consumption. Unfortunately with lower values hashrate drops dramaticaly or system freeze during startup (when miner starts). Lowering values from 1340 to 1250 drops hashrate (sometimes it freeze) and lowering from 1340 to 1200 or less freeze system every time.

I've read a some topics and many miners running core around 1150Mhz with no problems... but... @Windows

+ second problem: my system is not stable - restart occurs about 3 times a day. GPU's have modded bios + overclock, but i tried default settings and there is no change.

Do you have similar experience?

2x GPU (+ 2 GPU's will be added this week): SAPPHIRE NITRO+ RX 570
BIOS: Modified memory timing from 1750 to 2000
Overclock: core 1340 (default) + memory 2050 (default 1750)
