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

[mez]

Again:

Do not use -li and -ttli options for now, there is a bug there:

More info:

I will release an update in 1-2 days.
Added to OP.

we used to be able to trust your time table, but right now its shite.
Your losing a lot of respect over this.

No he is not.

Nobody cares if he releases it a day or two late. Its a very small bug, who cares.

Seems its not easy being a dev these days... people complaining about the dumbest things.

its more about his word, we could count on it. but lately that has been very difficult.
I had some weird bugs on windows with v12, one of my rx470 showed a NEGATIVE hashrate. imagine that.
Switched to linux now but v12 needs some fixing. perf on linux for rx480 is lower then on windows (20sol difference).
rx470 perf is about the same.

v12.1:

- slightly improved speed for some cards, about 410H/s on stock 390X, 450H/s on stock Nano, 290H/s on stock 280X, 300H/s on stock RX480.
- slightly improved stability. If it is still unstable for you, reduce "-i" value.
- fixed issue with wrong hashrate when "-li" or "-ttli" options enabled.

GREAT! will test it out now.

work only with 5 card on 6 cardrig, any "-i" value call exit on one from any 6 card (6x390x)(480-3x290-290x-390x)
back to 12

Also (before the crying starts again): on two of the test rigs (Polaris 470 and Hawaii 290x) I had to reduce intensity -i by one more notch to reach full speed. But it's still faster than v12.0. 390 Hawaii don't care much about intensity, could not yet see any difference between -i 7 and -i 8. Nice!

Claymore v12.1 running rx480 8G i8 not working for me showing 0s/s on all cards, 40G V memory?
Soz just noticed the need to reduce intensity thanks GH, running i7 and getting extra 15s/s great work mate

Did you make any improvements for Tonga cards in this release?

Yes but not much, I see 193->200H/s on my stock 380. I don't plan any further good speedup for Tonga, these cards are really weak for zcash.

[omshree]

Hmmm. tough its specified -i 8 it starts with 7 on nanos.

[Claymore]

Hmmm. tough its specified -i 8 it starts with 7 on nanos.

I disabled -i 8 for some cards because it does not work properly in most cases.

[omshree]

Well, on nanos they well fine I guess. Not a big diff, but sticking now to .0.

[DrYM]

On Claymore 12, Using ethos/Ubuntu & AMDGPU:

Sapphire RX470 4GB - ~290 S/s (Stock - Core: 1260, Mem: 1750).
Sapphire RX480 4GB - ~270 S/s (Stock - Core: 1306, Mem: 1750).

Running using -i 8 on all cards (tried to lower it as well, to 7 and 6).

Any suggestions how to improve the RX480 hashrate? Makes sense that out-of-the-box stock cards, the RX480 will have higher hashrates, for sure higher than the 470s, no?

[gennadiv]

R 9 380 performance has improved now personally I have issues 242 h

[spyshagg]

I have been running v12 + recommended drivers since the middle of last week non-stop on two rigs, not a single crash yet.

Yes, Tonga (1000/1500Mhz) 200-230H/s. Cryptonight is better, 560H/s with new sgminer-nicehash (Claymore-550H/s + 2.5% fee).

[dumpida]

The speed increase for the 12.1 over 12.0 is about 3% for R9 390. The power consumption is also 3% increase.

[marvykkio]

but increase for rx 470 and 480 I have not seen in version 12, and even in version 12.1

I have 700hs with R9 380 moded bios
with clymore v12.1 about 250sol same card same bios.

Yes, in Cryptonight from 560H/s to 650H/s on stock R380´s (no moded).

my R9 380 Nitro have Elpida memory and about 700Hs
