Miner- Optiminer/Zcash GPU miner v1.7!

Hi Optiminer and thanks for your great miner for Linux.

Given the main target is Linux and AMD GPU, have you ever considered using HCC (from the ROCm initiative) instead of OpenCL. I’m not a compute expert at all, but it looks like this could lead to interesting performance improvements due to the more optimized infrastructure HCC is using comparing to OpenCL (AFAIK, maybe I’m wrong).

This is also probably something better in long-term for people using a fully open-source graphics/compute stack.

Mine also coredumps on 1.0.1, running 3x7990 + 1x7970 on Ubuntu 14.04 with fglrx.
Swithed back to 0.6.0

use htop to check your CPU usage

Any news on the next release? Can you estimate when you’ll have something new?

Hi, I’m running with Ubuntu 16.04, but I can’t get the mine.sh script to work correctly. I have the cron job working correctly and when I restart the rig it starts mining with mine.sh but it does not restart the computer properly when a GPU starts hanging. Any ideas how to fix this?

The author seems to worry much about ssl and forgot all about us.
Miner stops at Got new work and it does not bother him…
A long time will stand still around 220-230 hash?

Since version 0.6.0 does not work

1253

I managed to get v1.0.1 working. Pretty much same hashrates on my RX470 rigs between 0.6.0 and 1.0.1, but like +100w @ the wall with 1.0.1. Was 830w on 6x GPU in 0.6.0 and now 930w. Although I can live with +100w if its more stable… but that is a little disappointing. May have to drop some voltages.

1254

Interesting…I got 60W less on Opti 1.0.1 vs 0.6.0 using three MSI on risers and one Sapphire Nitro 470 on mobo. In addition , I got 177H/s/card vs 168 before, so plus, plus.
All with default settings (no strap mods).

1255

I am busy working on a version with improved hash rate. There will be new releases in the next days.

Thanks for the update

1257

I’m a happy Optiminer user (thanks!) and am looking forward to the upcoming release.

BTW, I like the new feature adding TLS support for connecting to the stratum server. Encryption should be the default for everything for the same reason that I always use a seatbelt in a car. I would never say, “Today I’m gonna drive drunk and blindfolded, so in this special case I will use my seat belt!” Just encrypt everything, and always use a seal belt.

Version 1.1.0 released!

Increased hash rates. Improvement depends a lot on the model, older cards get a higher increase, RX 480 are about the same.

Well been waiting to update my rx 480 rigs with promised speeds increases so very disappointed you couldn’t put the work in to optimise rx series

1260

My “unknown” R7 model went from 58sol (1.0.1) to 64sol (1.1.0) (1m avg) ~10% increase :slight_smile:

Different GPU models have different bottlenecks, so some optimizations that work on one card do not give a speed improvement on others. But you should give 1.1.0 a try on the rx480 anyways… you might see a drop in power usage.

Hm, I’m getting an error on Windows 10:

[error] OpenCL error: cl::Context::Context() (CL_DEVICE_NOT_FOUND)

Any idea how that can be fixed? Claymore works fine on the same machine…

1263

Do you have multiple graphic cards? Try different platform: Add option “-i 1” or “-i 2” to the command line.

1264

Thanks for your quick reply!
I have three RX 480 Nitro (4GB) and one XFX RX 480 (8GB) in the rig.
Adding the -i parameter does not solve the problem…
