First GPU Mining Rig at Home - RX580

[Stoukie]

Good day everyone,

Seen some impressive cpu farms on the forum, this is not one of them

Finished setting up my rig on the weekend, currently only 3 GPU's but working towards 6.

Current Components:

GPU: 3 x Asus RX580 Dual 8gig (Hynix Memory)
MOBO: Biostar TB250-BTC PRO
CPU: Skylake Pentium G4400 3.3GHz Dual Core
RAM: Corsair Vengeance LPX Low Profile 8GB (2 x 4G)
PSU: Corsair HX1200i Fully Modular Platinum Power Supply
SSD: WD Green 120G SSD
Extra's: Powered Risers (Version 009s), Power Button and Mining Frame

Running Windows 10 Pro, installed the AMD Blockchain drivers (22.19.659.0 Crimson Beta / Win 10 64), no flashing of GPU's yet, also no overclocking and undervolting.

Currently getting at measly 17.5 Mh/s per card currently... Have some tweaking to do as most people get 30 odd Mh/s on the same cards...

Only mining ETH currently via the nanopool (eu1.nanopool.org) pool, will consider dual mining when I get a stable hashrate.

Claymore BAT File details:

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x38F9bb4df872CA8B2D5bFb398060D0c8fD85F005.Sion_Rig -epsw x -dcri 6 -mode 1 -ftime 10

Wanted to post a picture but it seems our Newbies cannot do so and work is blocking PhotoBucket  

Few questions:

 - Any suggestions on how to up my hashrate, I'm thinking of uninstalling all GPU drivers and reinstalling the latest, then do some overclocking/undervolting
 - For a someone with my hashrate which mining pool do you guys suggest I use for ETH
 - Any other suggestions/criticism would be appreciated

Thanks.

Use DDU to uninstall drivers, install the newest.

Set the timings yourself or download a BIOS already done.

Underclock gpu clock, undervolt, overclock memory clock. Voila.

Do Mod bios if you're using  PBE 1.6.2 it will copy your strap 1750 to above (1750 more stable)

 if PBE1.6.6 will copy your strap 1500 to above.  Use your original BIOS backup for safer.

Note: Using crimson relive blockchain driver it will fix Dag epoch fixed also patch your signature using ati pixel clock patcher/atikmad patcher.

Perfect, will reinstall latest driver after uninstalling it with DDU and download ROM from anorak and flash bios with ATI Win Flash, will let you know how it goes, thank you for advice.

Will try going this route with Polaris Bios Editor if downloading an already modded BIOS ROM does not work... Will remember to save my BIOS per card as backup.

Awesome, will give ethermine.org a go, thank you for advice

Right so last night I uninstalled all Radeon drivers, installed the latest Radeon Adrenalin Drivers, modded each cards BIOS (Polaris BIOS Editor) by changing the Memory Timing (strap) and did some manual overclocking/undervolting via Claymore BAT file.

All three cards are now hashing at 29.925 Mh/s

BAT File:

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x38F9bb4df872CA8B2D5bFb398060D0c8fD85F005.Sion_Rig -epsw x -mode 1 -ftime 10 -cclock 1150 -cvddc 880 -mclock 2115 -mvddc 880

Changed my nanopool payout to be 0.05, after payout I will try other pools.

The only thing bothering me is my nanopool stats:

https://eth.nanopool.org/account/0x38f9bb4df872ca8b2d5bfb398060d0c8fd85f005

Last night my 'reported hashrate' was 89.7 Mh/s but the 'calculated hashrate' was at around 60 Mh/s, few moments ago checking my stats again I see it spiked to 119 Mh/s... I understand the calculated hashrate is worked out on the amount of accepted share you submit, what bothered me when the 'calculated hashrate' was that low is that maybe the shares are stale, meaning it gets submitted before I can submit pointing to a network latency issue... I'm in South Africa, so maybe trying another nanopool server might stabilize it a bit better, will check...

As long as your SMA is at your reported hashrate or above it, your rig's performing well. Check the miner stats on your local PC for any rejected shares, but I would say that is not the case. Also take into account that Claymore mines a dev fee off your rig every hour. Correct me if I am wrong, but the switching makes you miss out on a few shares every hour or so.

Checked this morning and it showed 0 rejected shares. Looking at my stats again the SMA is currently above the reported hashrate, but will keep an eye on it thank you.

Will read up about the dev fee's thank you.

When the rig is stable for a few days I will experiment with dual mining and see if I can get a few cents on the side to 'play' with on Bittrex... Read SIA is not worth dual mining anymore, what are you guys dual mining?

[D1NG0]

For dual-mining, none in Claymore's current cache are. They all have dedicated ASICs or FPGAs recently enter the field causing mining difficulty to shoot up. GPU mining is not too feasible in them now.

On the bright side, Claymore's new version would likely feature support for some new coins to dual mine

UPDATE: I'm working on two new algorithms for dual, new version will be available in about a week, also I will reduce devfee for dual mode.

Ah right, let me try Sia tonight just to tweak my BAT file and make sure it is ready for the next version, thank you for the heads up.

[D1NG0]

Sure, but don't expect any quick payout. Most pools have it at around 500SIA and that would take a long while on a 2GH/s hashrate. If you support the currency and are in it for the long run, go ahead. You can improve your rig over time and eventually reach a payout. Bitmain's A3 miners work against you though.

Everything working good?
Here is some other advice (edit the settings directly in bios)

Congratulations on building/buying your first mining rig.
At first sight, you are getting really low mining speed on dagger hashimoto. Go and try modifying your card bios, so you will be able to get arround 28-30 mhs.

[Bigdrago]

What is the bios switch on the card for?
Is it 2 identical bios?

[Bigdrago]

Borrowing your thread.

I have 2 new rigs setup. (1x rx 570 micron nitro+ 8gb and 1x rx 570 nitr+ hynix 8gb). I will connect 13x gpu to each motherboard.

Here are my numbers after 1 hour of mining. Pbe "one time click" + some undervolt, underclock and overclock.

How are your numbers compared? Using nicehash.

This is indeed what I had to do as well. Initially mine ran at 18 Mh/s as there was a bug in the driver.
