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

[atrade06]

Claymore
After the transition to version 4, 2 farms 6 (6 * RH480 8g) began to give a blue screen with an error 0x000000ea. In version 3 it worked stably.
I can not use because the driver version 15.12 in RH480 card me. What can be done?

thanks

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.

Had a crash while I was sleeping on my 290 rig.

Not much in the log but it looks as the gpus started crashing, watch dog restarted them a few times and finally crashed out completely.

So 16-16x risers could be better?

I love nvidia cards. I'd like to have reason to buy them in bunches.

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

pfft, next time try sleeping on a bed!

MAN!! Please, always stay with us! You are the Best around the world!

I'll never set -nofee

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 would also like to know this question.  Can someone help us out?

[Sam123]

Ty Mr. Claymore . Perfect job as always.
I have 12 rigs 6x390 and all works fine ~6400 h/s.
I tried to mine Zcash classic with Miner 4.0 at zcl.suprnova.cc and expect ~70Zcl/24h but receive 45, so back to Zcash
Is this miner full useable to mine Zclassic

Claymore , Same question: can we use it to mine Zoin?

Thanks

Been running v4.0 for ~18hrs now but flypool is showing 15% less hashrate.

Anyone have a similar issue with Flypool ?

Mining software hashrate vs pool hashrate for those that asked (not shares). I know Flypool increased to 1000H/s for diff.

Just curious maybe its a pool thing.

what is the best CPU for mining with claymore v4 with 6 GPU RX480? I am not mining with cpu and it is load on 98% and all of my cards reduced hashpower to 55. When i mine only 2 the hashpower is 79 per GPU. CPU is Intel 1150s G1820 2.7Ghz only 2 logical cores. I mod my all RX 480 with only change memory timing.

tanx man. your miners are best

Zioin seems to CPU miner only right now (at least on the supernova site thats the only miner they suggest)

Use -t 0

@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!

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?

With the new miner(4.0) I'm seeing big benefits from clocking the GPU core higher.

1325/2150 sees my RX480s sometimes hit 90 sol/s with -i 0. So try clocking the GPU core more before BIOS mods.

Those are awesome results!  Can you do that in WattTool or do you have to use AMD Setting (wattman). Could you screen shot your settings?

You can use WattTool or MSI Afterburner(What I actually use), you don't need a screenshot. It's not rocket science.

I thought Afterburner wasn't compatible with the RX 480s... I must have missed an update. Thanks
