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

[Claymore]

v12.6:

- added Vega cards support (ASM mode).
- added ASM mode for RX460/560 cards (+20% speed).
- new GPU sorting method for AMD cards. Now GPUs are sorted by physical bus index (it matches AfterBurner list of GPUs). Also the list of temperatures/fans matches the list of GPUs automatically.
  Therefore "-di detect" and "-gmap" options are not necessary and not supported anymore.
  WARNING: be careful if you use use separate overclock/temperature settings for every card, due to new sorting method GPUs can get different indexes!
- added fan/OC support for 17.7.2 (and higher) drivers.
- improved support for systems with more than 10 GPUs, check readme for "-di" option description for details.
- added pool selection in runtime ("e" key).
- a few minor improvements.

AMD Radeon Vega Frontier Edition @ stock clocks:

GPU #0 recognized as Vega

ZEC - Total Speed: 311.773 H/s, Total Shares: 0, Rejected: 0, Time: 00:00
ZEC: GPU0 311.773 H/s

That's bad. Worse than a 280X

At startup the miner shows a notice that you must wait about a minute to get correct hashrate, but he ignored it, so he got some random number. I get 440H/s at stock clocks.

Thanks for this new feature I was waiting ages for this!

Could I please have your launch configuration + OS + driver version?

Windows 10, beta (closed) drivers. Probably it throttles, add "-tt 50" option to "config.txt".
UPDATE: my bad, I really see 310H/s in Windows 7 + public drivers. So it is either drivers, or Windows version, I will check it right now.
UPDATE2: it is drivers. If I use public drivers, I can get only 310-320H/s. For beta drivers, I get 440-450H/s. AMD should release new version of drivers asap, current public drivers are bad.

Thanks for the very useful info.

AMD Radeon Vega Frontier Edition (Air)
OS = Windows 7 Professional SP1
Driver = Radeon Vega Frontier Edition 17.6
Average Solutions per Second = 310 (throttles if you let it run for 10+ minutes)

AMD Radeon Vega Frontier Edition(Liquid) / RYZEN 7 1800X or Core i7-7700K
Will try later tonight with Windows 10 Professional or Ubuntu 16.04.3 LTS with beta drivers and report back

440H/s is worse than a Fiji, isn't it weird?

I was not able to make Vega work in Ubuntu: gpu-pro drivers for Vega don't install OpenCL for some reason and my miner does not support ROCm. Though I could miss something because I'm not Linux guru.

440H/s is worse than a Fiji, isn't it weird?

It is about the same hashrate as Fury Nano. Yeah it is weird, but you can see that AMD has really bad drivers for Vega currently, I think they will improve it in the future.

RX460/560 cards (+20% speed)?Any tests?

In my tests 107H/s -> 130H/s on stock RX460 2GB.

hi all together,

the 12.6 version crashes after building the opencl Programs for the GPUs... i got 2 7870 Pitcairns in that machine and the Program simply stops running after that.
in 12.5 everything was fine ...

[Metamorph]

280x
Version 12.6 crashing.

OpenCL initializing...
AMD Cards available: 2
GPU #0: Tahiti, 3072 MB available, 32 compute units
GPU #0 recognized as Radeon 280X
GPU #1: Tahiti, 3072 MB available, 32 compute units
GPU #1 recognized as Radeon 280X
POOL version

and windows close.

[chafer99]

I use 12.3 version. My R-380`s Samsung mem. (1050/1600) ~ 250h/s, Elpida ~ 220h/s
Version 12.4 - 12.6 better on Elpida mem. ~ 230h/s (Samsung ~ 230h/s).

[trippcheck]

yes by me too

force close

v12.6:

  Therefore "-di detect" and "-gmap" options are not necessary and not supported anymore.

Really glad to see this feature! 

Too bad this does not work on my systems - fails to start on Linux 15.04 (15.04 Because old drivers are best drivers for old cards, and old cards are best cards because paid for!)

Crashes in seconds on Win 7 box.  Have not installed on Win 10 boxes. 

Waiting to hear more about others' experiences before spending more time.

What about unlocked RX460
As I know
Crimson 16.12.2 checks the bios

The same here... but with 2x 280x

[Claymore]

After some more tests I found the reason of possible closing/crashing, I uploaded v12.6 again, please re-download it.

Now works fine, thank You


And fix also if You can Remote 3.4, there is error with save to option_temp.ini

http://prntscr.com/g6biua

Older version like 2.7 works without problems.

[kiaas]

Claymore, maybe you should message Bridgman, an amd driver developer, on phoronix's forums. He's just found out your eth and zec miners haven't been detecting the opencl after phoronix did an article of ethminer, maybe could benefit talking to him.

[trippcheck]

now run
thx
