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

[lpedretti]

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

Nay, your version is actually faster than Claymore's on my RX480's

Claymore's faster for me on my 470's, and it's also considerably faster when the pc's cpu is a low end, i. e. an old sempron socket 939. Silentarmy's miner gave me around 10-14 h/s on each r9 390 and claymore's 49.
On high end cpu's it seems to be rather similar at least on my 470's

My rx390 8gb is recognized as 290 with 3072 MB. Is that any problem? Hash rate is ~45.

I'll switch the card which does not want to mine now, and will see what happens.

Just switched to another GPU, but same problem.
-di 1 will just stop at Total cards: 1

what about the power consumption? Has anyone checked it ?

106 w for rx 480 8gb 1350/2250 core with modded timings. Voltage is not modded. 52-55 sols

@claymore

i try your miner with 2 instances, it work fine, same hashrate.
but this give me a idea :
can you make a flag start for choose a config file pls ?
by default config.txt and if i put "-conf config-coinmine.txt" or "-conf config-nicehash.txt" zecminer use my config file.

Read "CONFIGURATION FILE" section of readme or OP to see how it works.

You need 3GB RAM or more.

83 Watts for Sapphire RX 470 Nitro+ 4GB @ 38 - 40 Sol/s. Using 1500 timing strip.

I have moded rom which was for eth to run my rx480s on 29mhs, but no difference with zcash on custom and factory bios.
rx480 44-49h/s

I'm running the miner (v.1.1) since today and noticed the following. At the start it runs fine, but after an half hour or so the zecminer64 process is taking 99% cpu load.

Also, bind errors (notice GPU0 jumping to 0 sometimes btw):

Any clues?

Read "CONFIGURATION FILE" section of readme or OP to see how it works.

That section say's
"If there is only one option in the command line, it must be configuration file name." suggesting you can rename the config.txt file but it does not say how to define the new name in the start.bat file,,,

what about the power consumption? Has anyone checked it ?

Its less then ETH mining.

Sure I noticed that, after switching from eth even fans are sometimes idle and it's much cooler in room. I mean genoil's miner was giving much less hashrate than this one, was wondering is there a difference between this two. I will able to check myself in a day or so and post here but if someone already checked I will sleep in peace

[elgi76]

just you put the name of the conf file
thank Claymore.

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

I know, this is crazy. I just took all my R7 370's off eBay that now I feel I was giving away too cheaply.

[AnorakSupra]

Windows has stopped this device because it has reported problems. (Code 43) for my 3rd RX 470.  Oh Windows...

[Za1n]

what about the power consumption? Has anyone checked it ?

Its less then ETH mining.

How many percent lower? My killawatt died . Couldn't measure.

I would say a good 18-20% lower. On a 5 GPU rig I went from about 600 watts mining ETH to under 500 watts, both are using pretty much the using same settings (I did reduce Voltage offset a bit more in Watt Tool). These GPUs have the BIOS mod (1500 strap) and I am also using Watt Tool to reduce voltages when mining either ETH and Zcash.

Yep, same here, most of my fans hardly spin anymore now that I switched most of my rigs over to Zcash mining. I am going to have to buy more rigs to stay warm this Winter.

[adaseb]

Biggest difference was on the 290. It would be crazy loud at 75-80% fan speed and now can't hear it at 55% fan.

Reference model 290.

[Swimmer63]

Questions for someone more knowledgable than myself.
1. One of my rigs has two R9 290's.  One has 4GB and the other 8GB.  They both get in the mid to high 40's H/s.  Does that make sense.

2. Does it make sense to mod these cards for zcash mining?  If so, what would you recommend in settings and mod software?
