Open Source ZEC (ZCash) GPU Miner AMD & NVidia (up to 45 sol/s on RX480)

[adaseb]

The 280X was a very good GPU, almost as fast as 290 in many algos.

When ETH launched, it was almost as fast as a 290, however since then its mostly been going downhill.

9.6 sols on 280x vaporx (win7, 15.12 drivers)

If the 290 gets like 18sol/s it should be at least 15sol/s or so.

Back in the Scrypt days it got 750Kh/s while the 290s got 900Kh/s.

When ETH came out it got 27MH/s while 290s got 31Mh/s

The same hasrate like Nvidia 750Ti ) at 30 W

[antantti]

Testing on W7 and 4 x 970, looks like it needs some CPU with this setup. Maxes one core on i5 hashwell @4.4GH, give it two cores and it uses 40-50% on both of them.

sols 17-21 depending on settings, cards with elpida doing better than samsung. TDP in 60-70% range.

On ETH you get about 16MH/s on ETH today.
Zcash and 280x gives me about 9,6 sols too

just run your miner on my ether modded rig RX470 nitro+OC 8 gig

and i am getting between 19/20 sol per card

4 card rig pulling 410 watts at the wall for everything

really good  only problem i have is its not stratum so i will not be using it. As i like to choose
my own pool and tbh i dont know how good  http://coinsforall.io/#!/coin/ZCASH

[Amph]

if i set 0 for the devices to be used, it still use the device, there is a bug maybe?

[tZKtdvt6]

It is simply wonderful!.
Thank you very much.

it seems ok, but power usage is at 50%

what are your OC numbers?

seems to be a lot of place for nVidia improvements...

can you share your config? i have a problem running six gpu with the cpu hanging at 99%

AMD are showing roughly the same, an entire rig of 380 cards run at 400w or so, meaning there is at least 100% improvement to make before they are even saturated or close to.

[t2yax]

there is problem with device choice settings.im laptop user.i wanna try my nvidia card.but it selects intel gpu everytime

i already played with cardplatform and use device settings

hi can someone help me? when i run windows miner i get this errors

what should i do? i have install latest drivers and cuda

i am getting the same error...so..solutions please?

[adaseb]

Anyone managed to get any older GPUs working like the Radeon 6990 ?

[tomothy]

Tried with a 6950; having difficulty.
Works on my laptop tho; booted right up hashes at 2.5/s lol

Woah where is the opencl version?  or is it not released yet?

I didn't think they were done with it yet? 0.2.x is just nVidia and CPU right?

[krnlx]

@eXtremal

have 100% cpu load on 6x1070 rig. (2 cores celeron) hashrate is 22-23 per card

Code:

 9951 krnl      20   0 53.309g 598484 479196 S 196.3 15.0  30:27.23 zcashgpuclient 

when running on one card hashrate is 26 on card

Code:

10674 krnl      20   0 29.165g 118208  93928 S  95.3  3.0   0:08.60 zcashgpuclient

so number of threads = number of cards and all of them loads 100% cpu and become a bottleneck on multigpu rig.

Can you fix it?

[jk_14]

can you share your config? i have a problem running six gpu with the cpu hanging at 99%

KopiemTu 3.0 image is ready-to-go with zcashgpuclient, just: boot, download zcash and run
so everyone with nVidia GPU problems may verify if there is also a problem under usb linux distro
(if problem is OS or HW related)
