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

[osnwt]

Hi,
I have couple of questions and it will be nice if someone can answer.

Does anybody use PCI-e Express 1X to 3 Port 1X card?
Does it has any effect on mining speed?
How many gpu we can have on Win10? Win7 and Win8 have limitation on number of gpu.
Does Claymore miner or OpenCL have some limitation on nuber of gpu?

I use it with ASrock H81 Pro BTC board, it has 6 PCI-e slots, one of which uses this splitter, and two cards are connected via it. So 7 cards in total. All 7 are Sapphire RX470 Nitro+ 4GB Hynix memory, and all 7 mine at exactly same ~212 Sol/s. This rig uses Windows 10. I've heard Win10 can use up to 10 cards, I do not know. I had issues with RX470 cards with Win7, no patch helped, 5 cards were maximum, the rest did not work at all (even 6th). Now I use Win10 To Go booted from USB flash, and it works perfect. It also works great with Linux. No drivers were installed by hand, Win10 found the PCI-e bridge automatically and installed GPU drivers.

How do you talk to Dwarf operator? I have seen there only e-mail addresses for contact and they have never answered to my mails..

I used public forum when I had an issue with shares. After that I posted details in PM, shares were recalculated and the issue was fixed (not for me only - for the EU server users, it was an accident case when stitching data from worldwide servers with Ethereum).

Also when my friend had an issue with CoinMine, he created a ticket using pool site and did not receive an answer. Then I post a PM to pool operator on forum and received almost instant reply that solved the issue. I don't like that, but seems that social networks and forums sometimes provide better support than emails/tickets. Don't ask why, maybe due to public nature of those requests...

Hi,

Fanspeeds stuck at 20%

I tried:
-tt -70
-fanmin 70

What to do?

After that speeds are all zeros and the rig freezes and needs a hard reboot.

Had this with ETH dual miner when some 390X card was overclocked too much. It is a hardware issue.

Yea perhaps. However it doesn't say which GPU it is.

verson 9 is useless it power down my computer so it is time to move to something else since it is not profitable with version 8

That's exactly why few people wrote here that hash rate race is not good if no explicit reasons for that since it does not increase profit but decreases it due to power bills. No one listened, now it is the result: more power, more expensive PSU setup, etc. And not more profit :-)

Many sites use SSL, including all google sites, and any shopping site, or generally whenever you login to anything. There may be hundreds of kilobytes, or even megabytes to load a page, and everything is still really fast.

Don't mix a warm with a soft (mining with shopping). When ETH dual miner was created, Claymore changed its default intensity from 16 to 8 to save few ms only. These ms cost some stale shares since after share is calculated, it should be delivered in time. Using -i 16 created larger jobs from CPU to GPU which can't be stopped until finished, and even those ms were important. Now we talk about Zcash, it has slower block time, but solutions itself are huge comparing to ETH ones (around 1300 bytes vs 50 for ETH), and all this now is encrypted in addition. So you have exactly the same case, but for some reason no one is concerned with it like it was for ETH.

Someone tells no one will see their addresses via SSL. If you are paranoid, you should not use exchange addresses. Install zcashd, mine to t-addr and move all to z-addr, send to an exchange t-addr, and no one will know who you are. No one except you will even know from what z-address funds came to the exchange. This is what Zcash was created for. You do not need SSL for that at all. Use right tools for particular task. I understand that 90% people here are home miners, they never read about Zcash: what is it and how it works. Still, it provides 100% security if you are paranoid and use it right. Without any encryption or closed source. That is the brilliant part of Zcash that is undervalued yet.

actually version 8 will only run at 200 h so it is not profitable. your statement is true if I have to up my psu to get 220 does not equal more profit

Nothing in GPU hardware error logs? (hwinfo)

[fmz89]

version 9 better than 9.1 in terms of spike power
testing your rig (use chrome open(use shortcut on taskbar) & close (use alt+f4) repeat it until power spike come and yur rig will shutdown)
 


claymore need to fix this, lol

[osnwt]

Yea perhaps. However it doesn't say which GPU it is.

In my case Ethereum miner disabled faulty GPU. In your case it says "ignored", so I don't know what to suggest. Maybe you don't have -tstop option, so it ignores it instead of stopping and logging.

Did you try AMD's Wattmann tool instead?

If that doesn't work take a look at this:

can't wait till the next version maybe it will be corrected

hi

for each gpu how much RAM and CPU my need for best mining Zcash???

rig 1 ..4 rx 470 4gb- 835h/s v9 claymore ..im used 4gb ram and my cpu is intel g3240 3.1GHz

http://zcash.flypool.org/miners/t1YdKS8sstWxxdNs8Vz5TMtEAogSfAaXg4s

my share found 187-200ms

what are you doing ...please help me please

[mettalmag]

oh as easy as that, but what about tons of rejected shares ?

[KrokoTill]

how can I enable worker names in case of dwarfpool i'm confused

Use only numbers as worker name, for example -zwal t1RjQjDbPQ9Syp97DHFyzvgZhcjgLTMwhaq.1
When I tried to use something like t1RjQjDbPQ9Syp97DHFyzvgZhcjgLTMwhaq.a1 in past, when setting up ETH mining, I got errors until I discovered that only numbers worked.

I use numeric system twall.001 and etc,
but all the shares rejected dunno why, trying different ports now

ok so so far no rejected shares on port 3337, lets wait 10 more minutes,
as far as I know dwarfpool doesn't support ssl right ?

Can't say I have much rejected shares with dwarfpool. Is your latency on accepted shares good?

At this point, last I saw it doesn't support SSL. Even so, I'm still getting considerably more from dwarfpool than flypool (didn't use to be that way).
