EWBF's CUDA Zcash miner

[m1n1ngP4d4w4n]

i noticed that the miner uses only the 83% of the card.....................................couldn't ewbf mine at 100%

try multiple thread (like putting only 2 card per miner instance) also use the usual environment variable to make it use the whole cards (as much as possible)

SETX GPU_FORCE_64BIT_PTR 0
SETX GPU_MAX_HEAP_SIZE 100
SETX GPU_USE_SYNC_OBJECTS 1
SETX GPU_MAX_ALLOC_PERCENT 100
SETX GPU_SINGLE_ALLOC_PERCENT 100

These settings make just sense with opencl. They do not have any influence on CUDA.
And certainly they are for AMD..

Oh really ? always used them, read somewhere it was useful in all situation, ok then.

EWBF any news for version 7 ? i think you boost up to 430 sol for gtx 1070 .

[Psynthax]

Update please!! Now I am forced to use nicehash since it is more profitable with their new miner.. 

[EWBF_]

Version 0.0.7b released.

smells fishy - no source code

moron really.

Ewbf nice getting speed of 510 on GTX1080 and 408 on GTX1070 nice thx

[wacko]

Ewbf nice getting speed of 510 on GTX1080 and 480 on GTX1070 nice thx

480 on GTX 1070? Holy crap, what clocks are you at? I'm only getting about 360-370 with my 1070s. Are there any special settings with this miner, something one needs to add to the bat?

Version 0.0.7b released.

Right same as NH! Good move.

Would you like to share your settings.
My 1070s running a little above 400...

For me this miner is about 5-7% slower than nicehash on EVGA 1070, but still worth it.

[ioglnx]

My GTX1070 are KFA² EX and Zotac GTx1070 Mini with Micron +150 Core +650 Mem
But it was a typo I meant 408 sol/s- was writing from my Smartphone over RDP :-/

Version 0.0.7b
Performance improvements. Old cards may be slower than with version 0.0.6b.
I wanted release it as fast as possible. So new solver can be less stable.

Indeed solver needs fixing:
Sofar 1 Bluescreen
2 Crashes of driver

\Device\UVMLiteProcess2
Graphics Exception: ESR 0x51c648=0x30000e 0x51c650=0x0 0x51c644=0xd3eff2 0x51c64c=0x17f

and

\Device\UVMLiteProcess2
Graphics SM Warp Exception on (GPC 3, TPC 0): Out Of Range Address

Never saw such failures before - maybe some new addressing of Mem or opcode?

its not if you run 2x exe then its ~4%

nicehash 420
ewbf    ~400 but a bit less power usage

Nice Work EWBF !!!!


180 sol/s more !

2x gtx 1080

920 sol/s

[jiggytom]

very unstable for me though...can't run same clocks as earlier, and PCs reboot.

Yes this version is more stressing and unstable than before.
Try to lower the clock speeds. I found out sofar that my KFA² won't run stable anymore with the new EWBF ..dunno why because before she ran 3 days stable with these clocks.

[krnlx]

works stable on linux for me.

Code:

GPU0: 384 Sol/s GPU1: 386 Sol/s GPU2: 387 Sol/s GPU3: 386 Sol/s GPU4: 384 Sol/s GPU5: 394 Sol/s 
Total speed: 2321 Sol/s

Strix OC, MSI X, Gigabyte G1 (1070): all stock clocks EWBF = NH for me

[reb0rn21]

Strix OC, MSI X, Gigabyte G1 (1070): all stock clocks EWBF = NH for me

might be true, because ewbf use a bit less of power and cards will/might boost more, my results were done on fixed frequency

[Psynthax]

Thanks for the update, getting up to 410 sols/s on 1070

[ioglnx]

Since I use it 5 blue screens, 10 freezes even at stock clocks.
Event lock messed with TST, GPC, ESR issues all over the bank..something is either wrong with the driver or the solver uses something erratically.
