ZCash/ZEC GPU mining

[suklee]

Claymore 6.0 is out. Another large bump in speed. My Fury (non X, default clocks) is now doing 200Sol/s

Feels like Claymore is doing black magic or something with this Zcash miner lol... we've seen huge jumps every version.

I think this is fixed in 6.0... Heard some talk about an issue like this in the forums. Not sure though.

whattomine doesn't seem to have reported many changes. Maybe the rate you saw was with the rally ZEC had last night?

6.0 fixed my main rig (290x + 3x 480) where 5.0 wouldn't start on the 290x. (I hadn't bothered to run a separate instance)

What's this Zclassic (ZCL) coin, is it a fork of Zcash similar to etc vs. eth? It's more profitable than ZEC at the moment.

Btw, what is Nicehash-Equihash on whattomine? How do you 'mine' it?

but the real question is: Can i mine the more profitable Zclassic with claymore? ..

 

[suklee]

No idea, only one way to find out I suppose!
(Edit: Claymore does work with ZCL)

http://zclassic.org/

"All mining rewards in Zclassic go direcly to the miners,
while in Zcash the founders take 20% of the rewards for the first 4 years.

We eliminated the slow start of 20,000 blocks that Zcash introduced."

with v6.0 my hash rate went up but earnings went down around the same time. I guess a lot of people upgraded to version 6 and global hash rate went up I assume.

Yeah my earnings are down too. Part of that is due to me still running SilentArmy v5 on Linux machines. Claymore 6.0 blows that stuff out of the water . . . for now.

According to pool results my Win10 box with a 390 and a downclocked 290 is outperforming a Linux box running SilentArmy on three 900 MHz 290s and a stock 270. And that's some crazy stuff right there. Hopefully MrB can step it up and keep SilentArmy relevant.

Also I'm skeptical of ZClassic. Poloniex doesn't even support it yet. So . . . I dunno. Might switch to it eventually if I find a quick n' easy way to convert it to ETH.

mining pool hub has an auto-switching port for Zcash and Zclassic

 

[poofyhairguy]

Also I'm skeptical of ZClassic.

Me too. The volume is only 60 Bitcoins. So if you mine some it might be harder to sell than regular ZEC.

 

[DrMrLordX]

ZEC is below $100. I may switch back to ETH soon.

Awesome, 70 Sol/s is 470/480 territory. Not bad I bet considering the power consumption. Any chance you can share out the executable?

Sorry about the late response, the flurry of Claymore releases took up some of my time.

After some more testing I noticed a bug with that release where each instance would take up an entire core. I've ended up using the executables from:

https://github.com/zawawawa/silentarmy/

As I didn't have VS 2015 on-hand to compile it. Currently with the GTX 1080 I'm seeing 90-100 sol/s with a power limit of 53%, core clock ~1500 MHz and mem clock at 5316 MHz. Pretty good perf/watt but otherwise not a performance match for AMD cards.

 

[Accord99]

Right now I am running my Hawaii rig so that the power at Kill-a-Watt doesn't exceed 900W (or if using 89% efficiency); that's 801W at the PSU level. When this PSU was 4 years old, it could handle 1125W per Kill-a-Watt. 4.5 years of constant use at 900-1000W has finally worn it out. Pretty good for a non-server grade PSU, but it's clear this PSU is going to need to be replaced before its warranty period runs out.

Does it mean if you exceed 900W you see stability issues? I wasn't clear before when I asked about the Kill-A-Watt because you mentioned the PSU rail at 11.5V and I wasn't sure how you measured that.

 

[DrMrLordX]

Don't yet have time to mess with it, but Optiminer promises big hashrate gains for Linux:

Check it out you Linux-heads. I'll be getting on it later today.

No worries, my RMA'd GTX 1070 will be arriving sometime today. I have my laptop with VS2015 installed so I'll compile a new executable there. 90-100 Sol/s is still pretty decent given the power usage but it it'll be interesting to compare what the 1070 is capable of.

Speeds seem to be comparable to Claymore. Nice.

On a properly working quality 1KW power supply, 900W load shouldn't be an issue for prolonged periods of time.

ZEC is below $100. I may switch back to ETH soon.

The ZEC difficulty went nuts today. That combined with the price drops makes it a little more than break even compared to Ethereum. Looks like the party's almost over.

 

[DrMrLordX]

Optiminer is real folks, at least at first glance.

Machine ZEC3 that has a 6h average of 309.4 Sols/S reported by the pool is reporting a rate of 580-640 Sols/S locally using Optiminer. As always I'm going to let the pool tell me what's really going down . . . but yeah, it looks good.

It's getting close yeah. Probably another week it'll be break even.

 

[DrMrLordX]

I have restarted ETH mining on my Win10 machine to compare earnings potential. But my ZEC earnings are getting pretty low with ZEC down at $77 and the difficulty being as high as it is. Plus as good as is Optiminer, it's crashing on one of my cards which just happens to have a clockspeed I can't alter via software (which is really annoying; od just refuses to work for that card so its stuck at high defaults). So I'm losing hashrate from that.

 

[poofyhairguy]

It's getting close yeah. Probably another week it'll be break even.

Depends if Claymore has another few 20% boosts left.

 

[DrMrLordX]

Hmm. Looks like ETH difficulty is high enough that mining ZEC is still 2x more profitable for me, at least on my Win10 machine. Basically:

ETH (using Genoil 1.1.7) = 45.9 MH/s for ~$42/month
ZEC (using Claymore 6.0 beta) = 278.9 Sol/s for ~$81/month

 

[thilanliyan]

Yeah, ZEC is still more profitable for me, and easier on the ears since it uses less power.

 

[lienad216]

Welp... Claymore released another one....

390X (1100/1500) getting ~230 H/s

 

[thilanliyan]

Getting 215 S/s on my 1100/1250 R9-290 and 150 S/s on my 1100/2000 RX480 8GB.

 

[Shmee]

Another impressive bump!

 

[DrMrLordX]

I'll update my Linux instructions post later to point to provide instructions for Optiminer.

Claymore 7.0 pushed my Win10 box to a reported 380 H/s. That's +80 H/s over the reported speed from 6.0 .

 

[poofyhairguy]

Claymore 7 gave the biggest bump to my Tahiti cards, but a boost all around.
