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

[adaseb]

What cpu should I buy to improve my solrate?
I have now celeron g1840 and my best rate is with -i 0,
with -i 1 is less and with -i 2 my rig freezes.
Higher "-i" have no impact even if I choose only one card with -di parameter :S
i have rx 480 rx 470 and r7 370

I have observed the same scenario and would also like to know the answer.
Will Pentium help? (I guess no, but maybe latest skylake?)
Will i3 be enough for 6, 7 card rigs, or we have to go i5?

I haven't heard anyone with an i3 complaining about 100% CPU usage, so an i3 is probably ok...i5 for sure. I would stick with haswell socket 1150 chips though so you don't have to spend extra on a board and ram...just drop it in!

My friends has i5 and his rig with rx480 hangs too on -i 2 intensity..

If it hangs, probably due to unstable GPU clocks, voltages etc, and not CPU load.  If CPU isn't fast enough, miner just slows down.  -i 2 may stress gpu too much.

buying new cpu just for this (run I2 instead of I0) is a bad idea, you never gonna paid you cpu back
better buy 1 gpu more with the same money

Ok but I have now cpu for about 40usd..
I found about 2times better cpu (according to benchmarks) for about 70usd.
So if it could give me few % more it could be worth it..

Its not worth it, going from a Sempron to a i3, I get less than 5% hashrate difference.

Pretty soon someone will recode this SilentArmy kernel and it won't rely on CPU usage.

Sometimes its not the CPU but the Riser not being able to handle all that bandwidth.

So 16-16x risers could be better?

Yes those will always be faster and less incorrect shares errors.

@adaseb I'm currently using the USB 3.0 powered risers on all my rigs (R9 290s and RX 480s 8GB).  Is there something better to use, i.e. 16-16x risers?  If so, how do you power them or is it not needed?  Thanks!

Right now don't buy anything wait until this kernel is improved and relies less on CPU usage.

Plus, he dislikes linux, because many things are harder to do

Just to say about that line...Coin always has 2 sides...it may be harder for you...but not for others.

He meant harder for Claymore to develop on Linux.

That's unfortunate, a new Silentarmy fork released today, which work on Linux and is faster than Claymore 4.0...

Seems only fast or as fast for the RX 470/RX480 correct? How are the 280x on those ?

But why should Claymore compete on all fronts?
He makes the BEST windows AMD miners. Let him stick to that.
This way others in the community have a chance to compete to make the best linux and nvidia miners.

ETH profitability = ZEC profitability for RX 470 / RX 480

With SIA dual minings its more profitable when you take into account the fees.

By Monday unless ZCASH goes up again, ETH will be more profitable since during the weekend everybody will have extra time to upgrade to Claymore 4.0, and the Nvidia people finally have a fast miner.

[suggsy89]

Does anyone have a good RX 480 Reference BIOS for Zcash?  I am topping out at 70 Sol/s, but I see folks claiming 80?

I'm getting 70-75 h/s, you are not far off, have you modded your GPU bios?

[carlo_0000]

the 380's need an optimization, it s the worst one and i have 95% of 380's 
even the 270 get better speed

if i could modify the bios for better ram timing to get it at 1500 i guess it would help
or maybe claymore can do some optimization in miner for 380?

There was a guy that modded the 380 for FREE somewhere on this forum for ETH mining. They had great speed improvements, try and search for his BIOS's. This was like 2-3 months ago.

Try this. Had it in my folder could be useful;). https://bitcointalk.org/index.php?topic=1620733.0

Yeah that's the thread I was talking about.

i google but i found nothing easy to use  and also i have all samsung memory (xfx, asus, sapphire 380 all 2Gigas)

Today there was a problem
Driver removal does not fix the problem
Everything works fine after a reboot began this error
card is on the test computer r7 370 and would like to understand what it
it does not see any miner, but it works great in 3D and different games all see it and everything works
ps also shows that it is present
What can be wrong?
thanks for the help

The 4.0 version provided about a 30% H/s increase for my system over version 3.1.  I have two RX480's on windows 10.  One card is 4GB, the other is 8GB and I am running the latest catalyst drivers.

Even though I am getting an increased H/s, I do not get credit for any shares on zcash.flypool.org.  Is anyone else seeing the same behavior?

What's your config and zcash address??

For the RX series mining, do you see the ZEC mining use more power than the Etheruem? How about the R9 390?

[rudane2014]

Can anyone tell me your speed with R9 380 4gb? I'am getting roughly 45 Sols/s.
Do anyone use a R7 370 4gb vaporX? Whats your seed like I'am getting 40-45 Sols/s.

I really want to compare so I can see if I'am getting the same speed as others.
Thank you.

in dual ether+sia mode my rig was consuming 900 wt with downvolts and was very unstable. Zec on V4 consumes only 640 wt and is very stable.

[Haryford]

In the http://www.coinwarz.com/cryptocurrency or what to mine, to calculate the profitability, shall we enter the H/s value  or the Sol/s value reported by the Calymore miner to do the calculation? For example, shall we enter 100 for the 390X?

You should use the Sols/s value from claymore miner.

[Meech]

Yes.  Claymores miner does work for zclassic but currently not as profitable.  Tested on 3.1.

I need help resolving high latency shares currently getting avg. 500ms on US servers regardless of pool.

I am in the midwest USA and zcl.suprnova.cc:4042 is at 187ms and that is through a VPN!

my whattomine link shows ZCL as more profitable than ZEC.
