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

[adamvp]

Have coinmine.pl support lowered devfee?

@Claymore

Rig 6xR9 390 1150/1500

v.1.0 - v.8.0 - 0 crashes for all the time.

v.9.0/9.1 – crashes each 10-15 min, various GPUs. (any -i value)

Something is wrong with this version.
Rollback on v.8 returns stability.

Again and again.
Problems can be:
1. PSU  wattage load
2. PSU ripple suppression
3. PSU voltage regulation at different load variations
4. Bad risers and other cables. (Least likely if still working in other versions)
5. Incorrectly configuring windows

can you please expand 2 and 5

2. Ripple is a phenomenon that occurs with all SMPSUs (switch-mode power supply units). It is the tiny fluctuations in a power supply's output voltage, on the order of tens of milivolts, millions of times a second. It is an artifact of the process of converting a sine wave AC input to a constant DC output.

Ripple is measured as a peak-to-peak value in milivolts, and is measured using an oscilloscope (software can not detect ripple, nor can a multimeter or voltmeter; you need an oscilloscope with a scanning frequency of at least 30MHz). The ATX specification sets these limits on computer PSU ripple levels:

+12V - 120mV
+5V - 50mV
+3.3V - 50mV
+5VSB - 120mV
-12 - 120mV

Why is having good ripple suppression important? The first reason is hardware lifespan. Ripple wears on several types of electrical component, the most relevant being electrolytic capacitors. The closer ripple levels are to a capacitor's rated ripple, the shorter its lifetime will be, and ripple exceeding its rated level can cause it to blow or perform poorly. Since electrolytic capacitors are found in your power supply, motherboard, graphics card, and many other components, having a power supply with good ripple suppression is a must for long-term reliability.

Another problem poor ripple levels can cause is one that will surely strike fear into the heart of every overclocking enthusiast. Higher ripple levels means lower overclock.

5. A lot off factors. You must check power settings first, turn off PCI-E power control.

that explains a lot, our hardware importer bought these for our 3x RX480 8G mining rigs http://www.zalman.com/contents/products/view.html?no=96
for last few days most rigs work without any issues, after V9 some of them had problems (maybe 3-4 out of 95) but after playing around with clocks mems voltage everything is stable now so far so good

Have coinmine.pl support lowered devfee?

I heard they are stealing shares, thinking to switch to dwarfpool

[Claymore]

This is the "carrot or stick" approach.
The 0.5% is the carrot for the masses to enter the SSL prison.
When the majority of the miners (sheeps) voluntarily enter the prison, the plain connection will be removed (stick), and escape will be impossible.
Then it will be easy to increase the fees at will.
Same story again.

Nice of you to compare people with sheep.
I'm not going to remove plain connection, so you still can try to remove 2% devfee and become rich.
I never increase devfee, only reduce.

Anyone noticed the post of the guy who circumvented the devfee with his tamper is gone.
Good news for Claymore and all the honest miners here.

Yes, thank you all for support, also thanks to mods that care about removing cracks from their forums.
I have enough experience in these games. These "hackers" think that all their cracks work.
Readme explains things about cheating clearly.
Of course it's possible to cheat and not to turn protection on, but it's rather difficult to see whether it's working, it's just a few %. So in most cases using cracks is similar to using "-nofee" option.

SSL was implemented long time ago for mining already but was removed again due to the increased network lag.

Lags can only create a pool if it spends a lot of time to encrypt/decrypt data, am I correct?
SSL connection is based on same sockets and it takes almost zero time on client side to encrypt/decrypt 1Kb of data.
I'm curious about server load, is it too expensive to use encrypted connections for you?

Lets not forget that miner is actually a plain money printing machine. And to whine about paying for that is kinda weird.

I use the Celeron 1620 for my miners, will that CPU not good enough to do the encryption? I am little concerned.

[golden0707]

Hi all! So why do we need to use encryption ? Ane benefit from it ?

no one will be able to steal your shares as simple as that

[Claymore]

Everything is better with bluetooth encryption!

you wouldn't notice any cpu load even if you were encrypting tens of megabits/s, not even talking about few kilobits/s needed for mining

[ioglnx]

This applies for proper SSL/TLS offloading - yes if not properly set on the pool it can cause heavy load and traffic.

For me?  No, not at all but as said before, I've never heard of redirected or attacks (mitm)  for miners traffic   it's no problem for me that you're using ssl for securing your miner against no fee wrappers etc but IMHO you should just say so -  I believe most people won't have an issue with it

You misunderstood.

I pay my fees normally.  I am a decent "hacker", not a thief.  I WANT to pay my fees, i don't HAVE TO.  I perfectly well know how to "adjust" my fees, to 0%, and anything to 0 - 100% generally  (layer 7 manipulation in a smart router)..  Even without any tampering at the data stream, you may pay 0% or anything between 1.9 - 9.1% fee.  Simple math.

That doen't meen that i will  do it, and even worst that i will propagate this to other users.  As a developer myself, i am exactly at your position.

That i am telling, is that ENFORSEMENT of your rights (or law in  general), must not hurt the life of 99%+ of us lawful users (citizens) because of the 1%- of thiefs.  This is a terrible foreseable future, and i strongly oppose.

You don't have to remove plain connection, the POOLS will!  You will have nothing to blaim for...  But the simple user will be obliged to follow SSL if he wants to mine.  This is slavery.

Thanks for your app.

p.s.  yes most people let others to think for themselves and blindly repeat every nonsense they hear, like sheeps.  Is it new to you?

No, you are not correct, it's not about CPU time.
SSL requires additional traffic for both sides which adds latency and latency is bad for shares.

I don't want to hurt users and I'm not going to do it in any way; if you think that I do it, I'd like to know more details. Pools won't remove plain connections too, I see no reasons why they must do it, you can ask pool owners if they are going to do it.

Hi all! So why do we need to use encryption ? Ane benefit from it ?

For past years miners never had a need for encryption and now SUDDENLY we need it.
It is of course pure coincidence this need happened after someone published a way to disable devfee. Right, Claymore?

Does anyone have mining speeds for RX460?

the 99% has always been forced to bear the actions of the 1% in all aspects life that is just how it is.

[philipma1957]

yes around 95

It's not the reason that someone published a way to disable devfee, all these tricks were known before that. May be it's the reason for 10% devfee miner, but not for my 2% miner.
Yes SSL is definitely good for devfee protection, but you can bypass it anyway if it's so important for you and in fact after reducing devfee by 20% I expect to lose some money. It's not a problem for me, I like encryption as a feature anyway. I never said that you need SSL, you can use plain connection if you like it.
And I will not remove plain connection to force everyone to use SSL as some people think.
