Topic: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux) - page 355. (Read 3839210 times)

i heard the 8 gig cards usually have a better quality of ram when it comes to overclocking.

no testing on my part, grabbed all reference 8 gig and have not looked back.

I tested the XFX Rx480 4 and 8GB versions and there was a miniscule difference at stock speeds.
215-218sol/s (4GB) vs 207-222sol/s (8GB).

There was a higher variance though. Using Claymore v9.0

IMO The rx470 with a custom BIOS pulls almost the same (I get 212sol/s) but at a bit less power and much less initial price and is a better buy.

why the pissing contest about value of SSL with mining?

let the users try it and compare their profits.

I have to chime in here after reading through the BS (and some not BS).

The dev, developed a miner for most of us that can NOT have the ability, skills or time to make it. They spent time doing this. I am sure this did not take 5 minutes . They keep releasing new versions with better hashing rates since the start.

He/she/it DESERVES to get paid for their time and effort. Simple as that.

If people complain and don't want to pay a paltry 2.5% or now 2% in my book they are dbags who are ruining pretty much everything in this world, expecting everything for nothing. Be it a crypto miner, pirated movies, games or cheap chinese knock off copies of everything. Freeloaders.

Without this miner we would NOT be making any money, or we'd be using less stable/less earning miners from others.


If you don't like the fees, write your own use a free crappy one and GTFO.

**My 2 cents**

what is speeds rx 480 4GB vs 8GB?

So its useless for end user. Why should i  protect dev fee ?

Claymore, with what software you worked before appeared mining software?

Absolutely no.

1. SSL encryption increases data size and thus latency. Even if you have ultra fast CPU, it still increases it. So no win here.
2. SSL prevents packet editing. This is not a concern for miners, but it protects dev fee packets.
3. SSL is not enforced literally, but having 2% fee vs 2.5% enforces it anyway. Not miner dev requests it from pools, but people. Smart trick.
4. SSL does not allow you to check what is sent on wire as was said already. You can trust Claymore, but other may (will) follow the example.
5. If Claymore thought about miners' protection he would better add a simple password protection for management port. Seems few people had issues when found their rigs mining for someone else. Easy to set it to read-only, but adding a password is also easy comparing to extra work to add an SSL layer and actually introduce it for open protocol using trick with the fee.

Let me guess next possible steps (I do not insist they are planned, just are possible):
1) Remove plain stratum and keep SSL only (less probable).
2) Reduce mining speed for plain protocol (no fee mode) and still provide full rate for SSL channel (and ALL will demand it from pools). Why not, it's exactly the same as 2% vs 2.5% trick, only better.
3) In addition to channel protection (to keep transit data safe) add also pool certificate check. This means that only few pools with known certificates will be usable with particular miner. If pool changes it (in rare case) - new version of miner is created. This way no one will be able to remove the fee outside of the miner (even using SSL proxy). This is for those who wrote above it's impossible. It's quite easy, actually, and I wonder if it already is in place.
4) Step 3 means people will hack the code to remove certificate check or rather to remove the fee at all. No matter how good a protection is, it may be broken. I've heard about hacked miners on Chinese forums, this time they will be much more distributed.
5) Step 4 means more viruses in hacked binaries. Of course, we use only original binaries, but it is possible. I've heard someone had BTC stolen after downloading some Windows Zcash wallet after Zcash launch.

So to make things clear: SSL DOES NOT help miners or their security in ANY way, but MAY reduce profits due to increased packet sizes, thus, more stale shares. SSL DOES protect developer fee only, but introduces extra closed layer in open protocols that is a very bad idea. And finally, using tricks like different fee, it uses people (like sheeps, do you like it or not) to put pressure on pool operators to add encryption (for less fee or soon for full rate?) that is useless for mining as such.

SNI is helpful

No kidding. Been there done that. You publish your software and one way or another is going to be used elsewhere for a profit

I can only stick a shovel up your ass

Nope. I have always believed in Claymore and genuinely thinks he is about our security and as we all know the most secure software is open source.

Why dont you do something useful for the whole forum and stick your tinfoil hat into a light socket, your not helping to improve mining in any way shape or form
 your just inventing bullshit for all we know the Zcash coin could crash and never be seen again. Im interested in how to mine efficiently.
  I dont care how much claymore is earning it must be enough as hes doing upgrades. I aslo dont care if hes left or right handed and all the other crap that
people come out with.

Go to msdn.microsoft.com and download the free version of visual studio. After go to YouTube and watch videos on c# c++ and open CL. In a few years you can write a miner

Man in the middle doesn't care about encryption lol. Very easy to implement. No need to write network drivers. For the miner the mitm is the pool that can decrypt the packet and forward it to the actual pool.

You mean like trying with, and without SSL to determine if it's worth complaining about?  

Hey Claymore ,
What would be a good place to learn how to code in general and how to code for miners in specific? Can you please guide. May be jsut 1 or 2 things that I need to get started.
Thank you

 LOL!  You're kidding, right?

So SSL introduction was not about security of the miners?

yeah,, and v.20++ will need nuclear power
