@Claymore:  please add a kind of trim() when processing pools.txt. If the pool line for Sia (at least) ends with email (at least) and a space char after it (...&email=user@domain[SPACE][NEWLINE]), nanopool (at least) gives connection error. Removing this space resolves the problem. It may be called 'feature', but I think that in URL request strings it is better to do whitespace trimming on both ends of string because the error message is not obvious for users and trailing spaces may be left unnoticed by many text editors.

The answer is above and many times answered: Claymore's miner is the ETHEREUM miner with extra bonus. You cannot use it to mine bonus coins without Ethereum. That's by design.

-eworker does not work for SIA with this miner, it seems to be stratum option for Ethereum, but SC uses getwork protocol with parameters passed in the URL string.

Also when you put some command line in Windows or Linux, there are special characters treated specifically. One of such characters is '&'. Here is a cut from manual:


The URL scheme used to pass arguments to pool uses '&' to separate arguments. This means that to use it this way the command line argument must either be properly escaped or quoted, so this character is not processed as command separator, but used as a part of argument string. So the line with ".../miner/header?address=X&worker=Y&email=Z" MUST be in quotes. Otherwise you will get error since anything after '&' will be interpreted as another command.

Another option is to use dpools.txt, where a pool for SIA may look like mine:


Since dpools.txt is not processed by a command shell (cmd.exe on Windows or bash on Linux), it does not require quotes.

Anybody reads what's written in the question?

First, it is Linux, there's no .bat file.
Second, it's not a miner log, it's system log, Linux kernel messages.

I think only Claymore can give any answers. But it might be the result of using amdgpu-pro drivers and newest cards. AMD drivers are not the best written software as was mentioned few times.

For those who has low hashrate on some rigs mining sia: you probably forgot to remove/adjust -dcri option. Default is 30, I used 40-47 depending on GPU. After adjustment I have around 0.5% lower ETH hashrate instead of 5% initially.

@Claymore: so what is correct -dcoin option: sia or sc (or both accepted)? In examples here you write 'sia', but manual says 'sc'.

A lot of rigs work on Linux, including diskless ones booted from USB flash.

BTW, what's the DAG file size now for Expanse? Won't this allow to mine Expanse using CDM on cards with 1GB of RAM?

This is a hardware-related feature many times explained in this thread. Take it as a bonus of dual-mining.

@Claymore:

What is duration of 390X GPU round when -dcri is set 8 and 16? I still can't decide what value is better. 16 makes higher hashrate, but increases some losses due to job changes. You estimated it as 1% but with what pool and rig hashrate (if they matter at all)? I think the GPU round starts when new block is found (that is, every 14 seconds), but what is the round time with both settings? I want to prove myself that 8 is better :-)

In short, is -ethi 8 still better than -ethi 16 in the long run, despite the hashrate reported?

Current CDM version is useless for rejects monitoring, it restarts if you have more than 50% of rejects, and if you run fine for 10 days you can easily have 5 days of rejects in a raw. Claymore agreed that it should use another method and I hope he will implement it.

As for the rejects, go away from DwarfPool, it went nuts last weeks with rejects. There are reports that any miners may suddenly start getting rejects with no reason. DwarfPool advocates usually say it gives max profit of all other pools. I switched to ethermine.org and worked for 2 days there. And I definitely may tell you that profit is EXACTLY the same. For my 272MHs rigs I had this on DwarfPool per day: 2.03, 2.05, 2.01, 1.85, 1.87 (WTF?), 2.01.... Plus few hours of rejects with zero income. On Ethermine I have 2.05 per day with no glitches, stats recalculations, rejects etc. And even with 1% fee (Dwarf had 0% until July to compensate some glitches). Ethermine may estimate lesser profit in Ether than DwarfPool shows per day, but in fact I have exactly the same. Keep mining @ Ethermine right now.

Not that much, actually.

If you looked at the youtube video by TecLab, they measured every supply source for 480 card (PCI-e 12V and 5V, extra 12V) and found that with some GPU tests (and mining is like hardest of them) the 480 card draws around 126W from 12V PCI-e, 92W from extra 12V + some from 5V PCI-e. In total, they had up to 255W in tests instead of promised 150 (75+75), including 65% more from PCI-e 12V than standard allows. No wonder why they burn motherboards.

In that case I see absolutely no sense replacing 390 by 480.

It depends on your router and is usually somewhere in advanced settings, port forwarding or virtual servers. RTFM for the router.

Hope so.

You can foward 1 IP address but many ports.

There are few options:
- (safe) run EthMan in the same subnet as miners, configure it to collect stats from them and forward ONE external port to a single web port of EthMan. Then you can see via browser all miners configured, but can't control them;
- (less safe) run miners with negative ports to allow monitoring only (not control), forward few external ports to miner ports, use single external EthMan to read stats from few fowarded ports of miners;
- (unsafe) the same as above but with positive miner ports, you can control them and anyone can control them :-)  say, change wallet to own to mine for himself.

I use the 1st option except I use own web utility instead of EthMan that runs directly on Linux (do not use Windows). It does not control, monitors only. But if I need control, I will add some kind of authentication to it.

There are different risers, some connect PCI-e 12V from MB to the same pins of Molex power connector, some do not.
Both are ok as soon as you do not connect different 12V from different sources to the same circuit. That is, if your riser does not connect internally molex and PCI-e 12V then you can power it from any 12V source. If it does, then I would only connect molex to the same PSU as MB or cut circuit to remove the interconnection to use a secondary PSU for riser.

In reality I prefer to power risers from the same PSU as MB to be on a safe side.

Forward external IP port to the web monitoring port of the manager running inside of LAN (use your router manual how to do so) and use web browser to check the web page.

On Linux?
For 79xx cards?

Really? :-)

From specs, 390X can use up to 375W (75 from PCI-e, 150*2 from two 8-pin connectors). In reality well-loaded they can draw even more. 375*6 = 2250W + MB (let say, 150). So 2.4kW*24*30=1728kW per month.

For reference, my 390X*5 diskless rig draws around 2030-2100W from the outlet mining both ETH+DCR at 16/47 intensity.
