Yesterday I, and 500 other people, received the following email from Nucleus.vision (the domainname matches):

The issue is that the Bounty Manager put all email addresses in the CC field instead of BCC. This exposes the email address of 500 people.
Guess what I received today? The first targeted phising attempt:

Worst of all, nobody from Nucleus Vision replies. They ignore my messages and delete my chats, as if it never happened. Shame on you Nucleus Vision.

It was a Windows limitation. Windows was limited to 8GPUs of the same brand, but since Windows 10 1709 this limit is now 12GPU.
Bear in mind that nVidia currently still has a driver limitation of 8GPUs. Only AMD has patched their drivers to reflect the 12GPU limit. So in theory you can run 20GPUs on 1 Windows 10 rig (12x AMD + 8x Nvidia).
MSI Afterburner also has a limitation of 8GPUs which they are not willing to change (the devs hate miners, so...). Claymore doesn't have any limitations.

I'm having the exact same issue with 2.6 and 2.7b on one of my rigs (4x RX470, 2x RX580) running the blockchain beta drivers from AMD.
However, on my two other rigs, 2.6 and 2.7b both run fine, both those are all RX560s with AMD 18.1.1 drivers.
Are you also running the blockchain beta drivers? If so, it might be driver related.


Many many thanks for this version! It was exactly what I needed!! Works like a charm on my two RX560 rigs using AMD 18.1.1 drivers with the following settings:
-cclock 1100 -mclock 2100 -cvddc 850 -tt 75

Thank you very much for your reply, Branko!

Ah, I see! Indeed, the Bandwidth goes up when the Memory clock goes up. Issue fixed

Regarding the low hashrate; You were correct once again! It was issue number 2: I had to change the workload from graphics to compute for each and every card. I just changed it for 1 card, as per AMD documentation it says: Note! In systems with more than one GPU, this option will apply to all GPUs in the system (https://support.amd.com/en-us/kb-articles/Pages/DH-024.aspx) But apparantly that is not true, at least not for my rig.

Once again thank you very much!!

Hi guys,

First of all, this topic has been very informative. Thank you all very much for sharing your knowledge and information  

Sadly, I didn’t do my homework before buying 12 x Sapphire Radeon RX 560 Pulse 4GB (11267-18-20G). I thought I got a good deal, only later to find out this model is severely gimped. As stated before in this topic, it only has 896 shaders, less TMU, 1500Mhz and less Bandwidth:

I can’t return them anymore so I have to make the best of it…. However, it looks like my card is just a softlocked ‘normal’ Sapphire Radeon RX 560 Pulse OC 4GB (11267-00-20G). I have been able to unlock the shaders to 1024, the TMU to 64 and my memory chips are also ‘normal’ MT51J256M3 (MICRON) a.k.a. they run at 1750Mhz by default.

I’ve tried different straps (from Wacko, Branko, One Click Timing from PSBEditor 1.6.7, the BIOS straps website with the Nyan cat logo and the ‘top secret’ 15Mhs strap) and was able to push this ‘gimped’ card to 12.1MH/s. Sadly, I can’t do much more because of the limitation in Bandwidth. It’s locked to 96 GB/s and I need the full 128 GB/s in order to push the hashrate even further. Changing/raising the TDP and TDC made no difference; the cards just keeps using the same wattage (which is odd I think).

My question: Is it possible to unlock/BIOSmod the Bandwidth to 128 GB/s as well?
@Branko: Do you see any room for more improvements in my BIOS mod?

For those of you interested in my ROM:
Stock ROM (without any modifications): http:// data .freek. ws/public/11267-18-20G/RX560_STOCK.rom
ROM with shaders unlocked to 1024 (no other modifications): http:// data .freek. ws/public/11267-18-20G/RX560_UNLOCKED.rom
ROM with unlocked shaders, Branko’s strap and increased max. memory frequency (for use with claymore): http:// data .freek .ws/public/11267-18-20G/RX560_12MHs.rom
(REMOVE THE SPACES IN THE URL. I could'nt link directly to my server, it got flagged my bitcointalk)

The last ROM (the one with Branko’s strap) will give you 12.1MH/s at Ethereum mining using Claymore 10.6 and the following settings: -cclock 1275 -mclock 2225 -cvddc 1000 -mvddc 850

Thank you very much for your time

V9.4 gives a lot more stale shares compared to V9.3. Anyone else having this problem?

I cannot login anymore. If I enter my passkey and click login, it will redirect me to the homepage without logging in.

Thanks, it works

Thanks for your reply! Hmm, did you already make this change, because I'm still seeing the same/having the same problem.

Also it used to work before, I didn't change anything. How come it's broken now?

Many thanks!

Claymore-Dual, like this: https://i.imgur.com/Gh54tW4.png

I'm mining ETH like I've been doing for the past week. It was working until 2-3 days ago, didn't change anything...?

Is it me or is the website partially broken? No revenue calculations, crypto icon is missing, no total online workers etc?

Many thanks for your reply! Ok, I will wait

Many thanks for this amazing tool! Documentation could be a bit better for newbies, but it's self explanatory once you start using it. Here's my feedback:

1. Telegram alerts are not working. I've started a chat with the bot and entered the API key. The bot ackowledges the key and says to enable Telegram alerts on the website, which I did. But when my miner goes down, no alert is sent via Telegram. Email alerts however are working well.

2. You only receive an alert when your miner is down, but not when it's back up.

3. Is it possible for the Android app to remember my API key? Every time I start the app I need to re-enter my API key.

4. Is it possible to implement push alerts into the Android app, similar to email and Telegram alerts?

5. My miner keeps saying 'Pool switches: ETH - 0, DCR - 0' even though I selected claymore-eth as miner in the config.txt. Why is that? I do not want to dualmine.

Many thanks!
