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

[Cryptozillah]

v1.1 fix:

6x GPU at Celeron G1840 works fine. My thankfulness

I run a G1820 in my 6 x 470 rig still on version 1, no problem.

Ahhh linux - Perfect. Just one thing after I runned it:

GPU0 28.521 H/s, GPU1 37.075 H/s, GPU2 34.292 H/s, GPU3 34.736 H/s

Here I have:
GPU0: sapphire nitro r9 380 4G
GPU1: sapphire nitro r9 380 2G
GPU2: sapphire nitro r9 380 2G
GPU3: sapphire nitro r9 380 2G

Why? Why same card with more ram (4G) gives me lower hashrate - a lot lower this are almost 10H/s

Second example:

GPU0 41.826 H/s, GPU1 30.778 H/s, GPU2 34.622 H/s, GPU3 32.086 H/s, GPU4 33.204 H/s, GPU5 35.325 H/s

So here I have
2 ASUS r9 380 2g
1 R9 280X
2 SAPPHIRE NITRO R7 370 2G GD5 L

Can somebody recognize the cards by the hashrate?
INCREDIBLE I get same hashrate from r7 370 like r9 380 (both 2G ram)

Any idea why?

@claymore

Are 380x optimized as well? Its getting way lesser hashrate as compared to 280x? 

[tytanick]

thx Claymore.
I implemented it in my simplemining.net OS

I can only get my RX 470 4GB to run at 1800 with the (1500 strap hacked bios). At 1900 or 2000 it gives BSOD. No idea how you guys can run a 4GB @ 2000mhz without instant BSOD.

The 380X is a completely different card from the 280X. You won't get similar speeds primarily due to the smaller memory bandwidth that the 380 has. Its great for games but not for mining.

v1.1:

- added Linux version.
- fixed issue with rejected shares after devfee mining.
- remove "-allpools 1" option if you use it and mine on miningpoolhub, suprnova, coinmine or nicehash pools.
- added "XnSub" support for Nicehash.
- fixed bugs.

PS. Read OP or Readme for updated samples of using on different pools.

I assume that "-allpools 1" is still required to mine in other pools, like nanopool?

great stuff 1.1 !!

Good job for v1.1.  The Linux version is a bit faster than my optimized silentarmy kernel... for now.  :-)

I can run my strap modded 470s up to 2000Mhz but it wont gain that much speed. I am trying to find the sweetspot, current at 1930Mhz.
No bsod problems on any rigs, i run strap mod on all my RX gear.

I am on Win 10 on all rigs.

Quite a bit more stable as well, not sure what it is about the silentarmy kernel but it's not as forgiving on the cards clock speeds as claymore's...

[Dvian]

Claymore - you are CRAZY man!!! 38sol/s from old r7 370\2G!!!! I'm confused! GREAT!

@claymore

7950/7970/280x are almost certainly performing better than 380x as they have a 384bit memory bus as opposed to the 380x 256bit memory bus, and this gives them more raw memory bandwidth.

There is probably nothing claymore can do about this "issue". 380x just don't lend themselves very well to mining ZCash it seems.

For similar reasons, my 290xs are all faster than my RX480s. 512bit memory bus vs 256bit memory bus. No amount of overclocking the RX480 memory bus makes up for the lack of memory bus width.

VERSION 1.1

Working fine for me on flypool.

Using a R9 280 (not X version) and getting 45-48H/s using 1200/1500 clock settings

I'm using windows 10 64bit, catalyst driver 15.12. Anybody know of any way I may be able to squeeze a bit more performance out my card for ZEC (sorry if its a obvious answer but i'm pretty new to all this)?

[Yerba]

6 x Sapphire RX 470 4GB - 210 H/s. And 450w from wall. Cards temp 60 and fans 20%. Awesome miner.

[seitrox]

The new 1.1 gives me 100% rejected shares on suprnova havent tested any other pools but since i dont need any of the features of 1.1 and i like suprnova.

What core clock?
I'm getting 42-43 on average on my 1500 strap MSI 470 4GB with core 1100/900 and memory 1850/900.

Exactly what I experienced.

With claymore I'm getting 32H/s with my 380X's - with amd gpu pro drivers. The nerdralph-silentarmy miner makes around 27 or so...

Does anybody know a way to squeeze a little more out of my cards? Would using the recommended driver make more hashes? Thanks!

[CoolnQuiet]

The version 1.1 beta reports the total speed as H/s instead of Sol/s like version 1.0. However, actually it is Sol/s not H/s since when I check my speed on my nicehash page it says so. Then, there is a typo needs to be fixed. As everybody involved in Zcash knows that 1 H/s equals 2 Sol/s.
