Optiminer/Zcash v1.7 (GPU, Windows+Linux, AMD)

[cracker666]

i get the same error with win 10 also could some one post a example bat for suppernova so i know im doing it right would very much appreciate it thanks as you can see im new to this and want to learn thanks

Adding "-c 1" fixed the problem for me.
I'm getting absolutely the same hashrate as with Claymore 9.3, running 470's and 380's. However, on a 6 card rig it needs 17.5gb of pagefile to run and I can't free that much space on 32gb ssd's. Claymore works fine with 10gb. If I strip down windows 10 to bare bone I could fit a 16gb pagefile, but not more than that.

Reduce the intensity by setting "-i 4. This should reduce the required virtual memory. It should not be much slower.

Hashrate for R9 380?

Yes, it uses less memory.

I see it can be monitored using Claymore's dual miner monitor for Android, but not with the Remote manager. Also, the miner cannot be manipulated through this port, right? It's in read-only mode?

not working - program stopped working... everything set properly

[snk0752]

Everything is working properly in linux. Actually, I have about 320-330h/s per r9 nano card with 15.12 fglrx.
Optiminer, thank you! Expecting a further performance increase in future releases!)

Version 1.3.0 released!

• Further device specific optimizations bringing up to 30% increase in hash rate!
• Fix crahes with optimized kernel under Windows.

Important: Version 1.3.0 needs GPU_FORCE_64BIT_PTR=1

4rd and 3rd GCN generation cards (Nano, RX4*0) currently run slower on windows than linux. Therefore I recommend to use linux with fglrx (Nano) or amdgpu-pro (RX4*0) for those cards!


New speeds (stock card, linux):
R9 Nano: 390 S/s
R9 290X: 285 S/s
RX 480: 260 S/s

Nice work.  Base on those numbers, it looks like you're the first to get GDS working.  But I'm guessing you haven't tweaked caching with SLC/GLC memory access.

Important: Version 1.3.0 needs GPU_FORCE_64BIT_PTR=1

Claymore recommends  GPU_FORCE_64BIT_PTR=0
What is the difference between values 0 and 1?

This post explain what does those settings, and as they state putting GPU_FORCE_64BIT_PTR=1 is good to put if you game at the same time as you mine (possible with process priority super low) because it will open your whole GPU memory for 64 bit adressing, if you do only mining, it's better to put it @0 because it could hurt hashing speed otherwise, well have a good read

nice 1.3 works great on linux with my rx 480's I get a higher hashrate than claymores with this miner.

[johnkill]

Great job.
Stable for win 8.1 and win10
Better than new Claymore v.10 and v9.3

for stock cards:
R9 290 ~300 sol
Sapphire Trix ~350 sol

if you find way to control or just show temperature will be amazing.

[christiano88]

I get 350h/s on avg with a 390 with a max of 375h/s at times, modded bios and oc+uv to 1070/1675/-75mv. Good job!

With claymore I was getting 325 on avg. Also fixed the problem I had a 1-2 pages back, it was the core clock that was too high combined with the uv.

can i run linux with some method at windows
for run these miner??

anyone to share cmd line examle ?

With version 1.3.0 and 1.3.1 i get error segmentation fault.
ubuntu 14.04 x86_64,  fglrx 15.20.3, stock r9 290x. So i moved to Claymore 10.

I tried -c option to determine the platform but I alays get the same error. I tried -c 0 and also 1 2 too. The interesting part of the issue it always says platform ''0'' in error message
[2017-01-08 20:19:55.974] [error] OpenCL error: Failed to list devices of platfo

Is it possible to use backup server? eg connect to server 1 if connection drops try server 2...

You are using an old driver that the dev does not test on. He tests using the latest Crimson fglrx driver, which is 15.302. I had problems initially with v1.3 using fglrx 15.201, but everything runs fine after updating to 15.302. I running Ubuntu 14.04.3.
