How to use -powlim ?
-powlim -30 (the gpu is limited to 70% power usage?)
Exactly, but only for AMD cards, it's not supported for nVidia GPU cards. The range is -50 to (+)50.
Hi, guys, I am new in the mine business, I live in Spain and I would like you to recommend me which video cards to buy, with good hash and low energy consumption.
This is what a got so far:
Asrock H110 Pro BTC+
Intel Celeron G3930 2.9Ghz
Kingston HyperX Fury DDR4 2666 PC4-21300 8GB 2X4GB CL15
HDD 80 GB
EVGA Supernova 1000 G3 1000W 80 Plus Gold Modular
Riser Card PCI-E Express
GPU = unknown
I would like your opinion, I do not judge anyone
Thank you
if budget is not an issue I recommend 1070ti
ETH 31.3mh/s
125-128w

Anything past 1060 is a waste for ETH. Use the card's powerful GPU to mine something more profitable and then exchange it to ETH if you love it so much.
How do you figure that? I get nearly double from my GTX1080 ROG/Strix OC than I can from my 1060. A 1070ti should get just about the same, and a 1080ti gets more.
Some 1060 cards work better than others: my Gigabyte 6GB GTX1060 gets 21MH/sec but my 3GB Asus card gets close to 23MH/s.

Right "-powlim -30" means 70% of default max power usage.
Why would one use that?
Both my GTX1060 6GB and RX480 4GB Sappire Nitro+ cards get best ETH hashrate at 70% of their power (-30) - by 15 to 20%.
