Title: RX 580 Asus Strix 8GB on Samsung Memory Post by: rawnet on May 24, 2017, 06:53:27 PM Hi,
This is my first post so HELLO everyone :) but... I've bought some Asus RX580 Strix (https://www.asus.com/us/Graphics-Cards/ROG-STRIX-RX580-O8G-GAMING/) with Samsung Memory and I'm trying to undervolt it to mine ETHEREUM. On stock BIOS I'm getting 24MH/s Now I've copied 1750 straps to 2000 and I'm getting about 27MH/s but with 180W power usage. Is it possible to lower power usage with that hashrate?

If yes, increase it to -100 and see again. You just have to test to find the best undervolting, core and memory clocks for your card till you reach something that satisfies you. Title: Re: RX 580 Asus Strix 8GB on Samsung Memory Post by: K1lo on May 25, 2017, 10:03:13 AM Still experimenting with mine, however I can confirm even at -96 mV it is stable and happy.
Additionally, the reduced voltage means the GPU can hit higher speeds which (although less important than memory speeds) still makes a difference. Title: Re: RX 580 Asus Strix 8GB on Samsung Memory Post by: rawnet on May 25, 2017, 11:54:31 AM Can You send me Your exact settings?

My current settings (more tweaking to be done later after work ;D) are: -96mV 0% power change 1300 GPU clock 2200 GPU memory Everything else is stock including the BIOS Title: Re: RX 580 Asus Strix 8GB on Samsung Memory Post by: rawnet on May 26, 2017, 06:38:05 AM THX I'll test it.
BTW Do You mine dual (ETH+DCR)? I've got some problem with it. When I'm starting dual mining (ETH+DCR) after few minutes computer hangs up. When I mine solo only ETH it works just fine - tested for 24h without any problem. Any clues? Oh... I'm on Crimson 17.5.2 Beta drivers.

Make sure you're not undervolting your cards as that caused hiccups in dual mining, also make sure the -dcri is lower than 30, sometimes even 20 or 10 to make it stable, just try different settings until one is.

My best settings for now: GPUClock 1050 MemoryClock 2000 GPUVoltage 987 straps copied from 1750 to 2000 4 GPU Asus Strix RX 580 on Samsung memory - 111Mh/s (Ethereum only), 525W from wall I'm very impressed by temperatures: about 50-55C Can anyone share their best settings for that card? Maybe some bios mod?

Just don't use the 1750MHz strap!If you will have Samsung use Uber-Mix! Look at my guide.

I have the same cards, they doesn't work with Samsung uber-mix straps Title: Re: RX 580 Asus Strix 8GB on Samsung Memory Post by: Mattthev on July 01, 2017, 08:24:51 PM k What? :DI have the same cards, they doesn't work with Samsung uber-mix straps Title: Re: RX 580 Asus Strix 8GB on Samsung Memory Post by: lcnmrt on July 01, 2017, 11:01:18 PM edit your start file -cclok 1200 -cvddc 980 -mclock 2100
