Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

Hi all

Can anyone help me with 480 nitro+. After I change my bios on mod and restart my PC, my rig dosen't work?
Do I have to reinstall my drivers or something?

I am assuming you are in Windows 10 so yes the windows need to "see" your new GPU's bios mod
They will start going black screen and appearing in a loop trying to cope with the change.
Do a reboot after that and if the cards are not recognized as they should you have to do a DDU and reinstall the drivers

I give it a 70% chance that you will need to reinstall drivers 

I did DDU an reinstalled my drivers and  still have the same problem. Driver menager shows me an issue with this card

Hello guys ,

 I have  1 RX 480(primary)  , and i get a R9 fury Nitro in second place but when i launch the miner only Rx 480 work , R9 hasrates is 0.
But The miner see the 2 cards. Drivers tested 16.6.2 -16.9.1 -16.11.2.

GPU #0: Ellesmere
14cc   GPU #1: Fiji
14cc   ZEC - Total Speed: 282.283 H/s, Total Shares: 0, Rejected: 0, Time: 00:00
14cc   ZEC: GPU0 282.283 H/s, GPU1 0.000 H/s
14cc   Pool switches: ZEC - 0
14cc   Current ZEC pool share target: 0x00083126 (diff: 8000H)
14cc   GPU0 t=45C fan=48%, GPU1 t=39C fan=28%

if u have any idea

Since you are using a custom BIOS the driver you use will either have to be older than 16.12.1 (AMD started BIOS signature checks in this version and newer). If you are windows 10 there is a workaround to doing this using the newer drivers. I use 16.12.1 for my ETH rig since my R9 380 runs better on that driver than older ones. You can find the guide here: https://www.techpowerup.com/228536/amd-bios-signature-check-re-enabled-with-relive-locks-out-polaris-bios-modders.

You will need to have physical access to your rig to do this it requires you to boot into "Safe Mode"

Also I would like to know the results of your BIOS mod since I have 2 of those cards running ZEC currently unmodified.

I have a friend running a fury and its picky about drivers. He is currently using 16.3.2 doing about 450H/s unmodified. Issue is you can't use 16.3.2 with the 480 so you will need to separate them in order to use both of them for ZEC.

[JeanMiche]

yes can't use 16.3.2 for RX 480 :/ so i can't  use the 2 cards in same computer ? i must to do 2 computers ?

Hello guys,
I have problem with my rig. Several days ago Claymore zcash miner began crashing. I get message: GPU 1 hangs in OpenCl call,exit. And after that miner freezes. What can I do to solve this problem?

You could try newer drivers but the Fury's are quite picky with drivers. At that point would be trial and error or if anyone else has successfully ran a newer driver with the Fury. I would just use 2 different machines for them. Better in the long run and if you plan to expand it gives you options of creating 2 different rigs for more diversity as well. Good advice for anyone mining is keep like cards of similar generation on the same machine to avoid driver issues and not mix and match.

Use -wd 0 to avoid freezing of miner. And decrease the clock on GPU1.

I tried that. even if I use the -wd 0, there is still watch dog information display. Is that normal?

Guys my SAPPHIRE 280x 3GB is only using 5 intensity and mining at 290H/s, is this normal? shouldn't it be running at 6 intensity? i tried forcing it but says not enough memory
anyone else have the same gpu? do u guys get the same thing?

It depends on the mem type the card has. I had a XFX R9 28X Black Edition with Elpida memory and could barely hit 296H/s out of it. Where as the same card but with Hynix memory was capable of 320H/s so more than likely your has Elpida memory or just not OC'd at all. And I ran mine on -i 5 as well because -i 6 didn't work either.

Is intensity really an issue? I get same speed from my Cards regardless if I use I 6, 5, 4 or even 3. The only thing affecting my hash is voltage and core clocks

my hashrate has dropped from 165h/s to 150h/s

i switched from minergate pool to flypool
i was getting 165h/s on minergate pool, but when i switched to flypool, i started having 150h/s
i switched back to minergate pool and still same 150h/s

what could  be the problem?

If you restart the computer, is that still 150H/s?

yes... same.

You may need to lower your overclock on that particular GPU and/or raise the voltage (if you undervolted it) to fix the invalid shares issue. Try reverting it to stock settings for testing first of all.

All gpu´s are in stock clocks and not undervolted.

With win7 everything was working 100%

Hmm, if you're at all stock settings then you're using ~250 watt per GPU? You might not have sufficient power if that's the case since 7 x 250 is 1750 watts just for GPUs...

Hey, good point, havent even think about that, have to learn how to undervolt those

You could use MSI Afterburner to reduce the mv on the core clock as well as reducing the power limit. Unfortunately you can't undervolt the memory with that program so I am using AMD's Wattman for all my tweaking right now, but that doesn't work with R9 280 series as far as I know. Perhaps wattool would work, but I'm not sure. Afterburner will help allot even without being able to undervolt the memory.

Hi, Thanks for this, Measured the power usage today and it was 1650w, So could it still be power problem? Rejected shares are coming very suddenly, 5h mining and 0 rejected but sometimes after 30min mining there can be 2-3 of them, Mining on Claymore´s dual miner there is no that problem, rock solid after 24h mining

Something else worth of try?

Hi, I got 5 RX570 but Claymore one recognizes 4.
The AMD Radeon control centers also shows 5.
I use this driver: non-whql-win7-64bit-radeon-software-crimson-relive-17.5.1-may4.exe

Any hints?


Sorry, was my fault, it 570... can't claymore handle the 570's?

Check Device Manager in Windows. If the 5th card is disabled, you need to mod the drivers to use more than 4 cards on Windows 7.
