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

[Claymore]

Try silentarmy versus this - at least on Linux, it seems... the same. So I poked around and pulled the IL and ISA from Claymore's.... the shit IS basically silentarmy, from what I can see. I didn't check every kernel, but it looks like it.

Have you implemented your own kernel for ZEC PoW? If it has good speed, it will look like silentarmy because there is no way to create really different implementation of fast binary tree for Wagner's algo, especially on GPU. But it does not mean that it is silentarmy code. Another example is blake implementation - implement it and its machine code will look similar for all possible implementations because it requires a concrete set and order of operations.

... even with "-allpools 1" set there are DefFee: ZEC: Job timeouts in V2  

... seems to be a problem with the eu pools. Once it hits us1-zcash.flypool.org it works.

Just tried version 2 on a miner with 7970s and another with 370, hashrate decreased by 20 points. From 110h/s to 90h/s, for the first one, and 140h/s to 120h/s for the second one.

[halker2010]

v2 report
7950 went up by 5 % to 43 h/s
r9 380x same about 31 h/s

anyone with r9 380x here gets more , can u help me with this ?

[Tmdz]

on 2.0

High cpu usage and it hard crashed on one of my rigs with 290s, went back to 1.1/

Which is a royal pain in the ass to get going again after hard crash because this is my trouble maker rig

[golden0707]

Confirming huge CPU load . due of that lve got hashrate drop from 270 to 230-250. 2*470+4*280x
Back to 1.1

[Claymore]

I had to remove v1.0 and v1.1 from google drive and mega, because I was pointed that I used a small part of mrb's work.
It will take up to 24 hours to revise my code and create own implementation, then I will upload updated version.

Details are:

Code:

mrb> Of course this is only ~100 lines of code, and we are all lazy programmers and I understand why you did it :) but you ought to do the right thing.

Oh, you are correct, I really missed this point. I was in a big hurry to release first version asap, so I concentrated on main Wagner's algo, 
blake is not interesting for me at this point since it takes only 10% of total GPU time and it's trivial in fact, blake algo is not that I can call something new. 
But to make some start point asap I included your blake.c into my sources and then forgot about it and did not create my implementation. That's what happens if you are in a hurry. 
It is very unpleasant situation for me, I will do the following:

1. I remove v1.0 and v1.1 versions of my miner. In fact, I already removed current packages from google drive and MEGA, I will upload updated versions soon. 
In next version I will remove your blake.c from my sources.
2. I apologize, it's only my fault that I used this part of your code. I was not going to do it in public version.
3. I want to send you some compensation from my ZEC dev fee if you don't mind, just send me your ZEC address.
4. I'm not going to hide my fault in any way, I will post this message in my miner thread in first post.

Thank you for doing the right thing. I fetched your new tarball Claymore's ZCash AMD GPU Miner v1.1 Beta - LINUX - Catalyst 15.12.tar.gz and can confirm you included the MIT license as mandated in your "Readme!!!.txt" file, as quoted below.

You are in no way obligated to "pay" me. But if you feel this can help re-establish some of your image and reputation, feel free to publicly send to my donation address t1cVviFvgJinQ4w3C2m2CfRxgP5DnHYaoFC

You are now fully compliant with the MIT license. I hope my SILENTARMY code was useful to you

I'm happy that we close this issue! I also donated 5 ZEC (about 2BTC at current prices) to your address t1cVviFvgJinQ4w3C2m2CfRxgP5DnHYaoFC

CPU over 85%
hash rate like past and a little lower
I think V1.0 Beta better than other versions .

As I said earlier, I confirmed issue with high CPU usage and will try to fix it asap, this issue is related to OpenCL bug, miner must not load CPU.

Just tested Claymore V2.0
Got a speed bump on all my RX480 8Gb and RX470 8gb
V1:
46-50 sols

V2:
48-55 sols. Sometime even upto 57 sols!

GPU0 and GPU2 = RX480 8GB

Running modded bios.

Some said power usage are more. For me, it is about the same reading from my smartplug (with history log)

Note: GPU3 alway the slowest one even on eth and connected to dual 1440p monitor. I am using Core i7 3770 non-k. Had to turn off CPU mining to achieve higher hashing. Once I turn on -t 4. It slow down by 10 sols for all 4 cards.

cpu usage 30% with 3 gpu ( 2x 280x and 1 7950), hash increased with ~12 %

[sorry2xs]

is anyone experiencing any unpaid balance issues flycastpool not increasing for over an hour

[papasmurf1337]

How about Sapphire RX 480 4GB with 2.0 version?
45 or less?

is anyone experiencing any unpaid balance issues flycastpool not increasing for over an hour

Yes, same here, the Unpaid Balance display is not moving and no payments are being sent out.

[eamkkjub]

Same..

"Zcash is still alpha software, use the pool at your own risk. We cannot compensate any losses." So they collect some extra ZEC for themselves (again)

[miningpoolhub]

v2.0 is also working great

390 Hashrate increased from around 44 to 51

I think this miner or maybe more precisely the implementation of the mining algorithm is using parts of the rig that we did not previously have to worry about. I have several RX480 and RX470 rigs and they are all over the board from one another and I have yet to pin down the exact reason. Some rigs I can get close to 50 Sols/card (47-49) and others barely break the low 40's. Core and memory clocks seem to not work in the expected way, with lower clocks often meeting or beating higher clocked rates.

I have noticed the modified BIOS 1500 or 1375 straps does seem to help. Also as some suggested, tightening the core and memory clocks to be closer together also seems to help some. I have found that cards directly in a PCIe x 16 slot do perform better than those on risers, but not by much. Also it seems a faster CPU in the rig is also helpful.

submitted a ticket and not even acknowledgement Bailed for now 
Edit to many fees for that Shit
