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

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

20-23 sols on Gigabyte 1070 G1

it seems ok, but power usage is at 50%

what are your OC numbers?

same results:

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


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.

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

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?

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

sure:

Code:
root@kopiemtu:~/TEST/zcashclient-0.1.1# cat config.txt
server = "coinsforall.io";
port = "6668";

# Your ZCASH payout address
address = "zthTb2ToG5kuAc11Ni6NxoYjoxQdEr2XvST7XEdLvmHG9k7kotEcwYCaAn1SH4zRdPoXn9kNeFm8CQok9SNtNgn8d9WcdTK";

# You can give this machine a custom name
# Computer name is used as default
# name = "worker_name";

# Platform:
#  "amd": AMD GCN cards
#  "nvidia": NVidia Maxwell cards
platform = "nvidia";

# GPU crash handling (properly untested feature):
# 0 - do nothing
# 1 - close miner application
# 2 - reboot system (need superuser rights)
onCrash = "0";

# - The following settings have one entry per GPU
# - If you have more than 4 just add more entries or leave it as is to use defaults
# - All entries must be separated by commas and set between double quotes

# 0 = don't use device
# 1 = use device
devices =        ["1", "1", "1", "1"];

# work sizes
worksizes = ["256", "256", "256", "256"];

# threads
threads = ["8192", "8192", "8192", "8192"];

# -1 means don't change
corefreq =       ["-1", "-1", "-1", "-1"];
memfreq =        ["-1", "-1", "-1", "-1"];
powertune =      ["-1", "-1", "-1", "-1"];
fanspeed =       ["-1", "-1", "-1", "-1"];
root@kopiemtu:~/TEST/zcashclient-0.1.1#


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)
