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

[Meech]

No problems yet with 2.0.  My rx480 8gb went from 42 to 50 stock settings and r9 290 from 45 to 55.  My r9 390 didn't improve much from 34 to 38.  My rig isn't headless is that why my main gpu (390) is less?

[bmwM3]

I also have good results from v2.

My r9 290s are doing 58-61 sols

My 470 8gb is doing 48-50 sols.

What settings and rom are you using on your 290s?

Thanks!

Are your 290s modded?

[Trimegistus]

Testing v2 in one of my rigs:

6x480 4GB went from ~210s to ~220s

Celeron CPU went from 10% to 80%

Conclusion: not worth it!

[crypsy]

Nice. ~200sol/s from 6x380 and ~950w
cpu 1820 75-80%

[doktor83]

it's a lol that version 2.0 in task manager isn't displayed as zecminer64.exe, but nheqminer.exe (nicehash)

can u share gpu model and cpu

[delle54]

280x up to 47-50 Sols now @ 12.15 drivers

i feel soon 280x is gonna be best cards for ZEC

Same here. Even up to 50.

[andreynk]

is there any difference in hashrate (or s/s if u like) between win and linux clients?
have both OS on my rigs but can't compare because they are loaded with different cards.

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:

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

My 470 8gb is doing 48-50 sols.

Are your 290s modded?

can u share gpu model and cpu

1 x Sapphire R9 290 tri-x not modded but overclocked to 1100 core clock
1 x Sapphire R9 290 dual-x same as above
1 x MSI RX 470 8gb modded. Used 1750 timing for both 1850(i think or maybe 1875) and 2000. Core clock is at stock 1242 but memory is overclocked to 2000. Stock is 1650 which is really bad.

CPU is an old i7-2700k 3500 sand bridge.

[king_pin]

I dont see any increase in speed with v2.0 on my 7XXX/2XX!
 You probably should have a more powerful CPU, because on my CPU week rigs I even see a decrease in hashrate.

[HashZilla]

Reached 50 sols on rx 470. The only problem is the CPU usage tho. Thanks claymore.

Details of your GPU and setup if you don't mind?

[arielbit]

v2.0:

- improved speed by 5-15% (depends on card model).

About 55H/s on stock 390X, 52H/s on stock 390 and 48H/s on stock 280X.

280x, 48-50H/s
390, 55 H/s (touching up to 60 H/s from time to time)
290x, 55 H/s (touching up to 61.x H/s from time to time)
rx 480 46.x - 49.5 H/s
fury 52 -58 H/s

Reached 50 sols on rx 470. The only problem is the CPU usage tho. Thanks claymore.

Details of your GPU and setup if you don't mind?

MSI rx470 4gb, using a custom rom ofcourse. Copy paste the 1500 strap timings to 1625, 1750 and 2000. 1950 and 950 mem. Core clock cap at 1126. i7 3770k. I'm getting around 48-50 hash per card. GPU-Z shows around 55-60 watt per card. I also have to say my temps are lowered too.

[Master-Peter]

Can confirm 10% gain on my dual 290x. From 98-102 => 107-111 H/s  

But higher CPU usage and DevFee timeouts.  

After killing nheqminer (was running on 75% - giving ~4 H/s) i gained another 4 from the GPUs. CPU was on 90% is now on 20%.

But I get Lots of "DefFee: ZEC: Job timeouts". I am mining on equihash.eu.nicehash.com:3357 and "-allpools 1" is set. I just reused the config.txt from version 1.1 that was running here 24h perfect.

[Relaqs]

I can start start amd tools, amd monitor no gpu info, no temerature etc use diferend drivers. windows 7 .
mining is ok. 4x R9 280x  157 M/h

[xleejohnx]

on a 6 card system with just a dual core with v2.0 it will max out the cpu and bring down the hash rate of the gpus. 216sols
v1.0 didnt do this. so im back to v1.0. 255sols

[Tmdz]

Zcash is now less profitable than etc, I think people will start switching back over.

Well we had a good 6 day run.

[Zywiec]

280x up to 47-50 Sols now @ 12.15 drivers

i feel soon 280x is gonna be best cards for ZEC

I can confirm 280x looks pretty awesome. I wonder where the peak hash rate could be, over 60sol/s?
