Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[dwu]

I read several pages and I still don't know if I should switch to his straps. I made a custom BIOS a year ago and I have around 29-30MH (Reported: mostly 30-31.5) for my RX480/580 4GB cards.
Probably my timings are not the most stable and memory errors are occurring on some cards too (I still do not fully know if it is actually bad or not), because I tried to push it to the limit. Sometimes the miner restarts once a day.

What do you suggest?
- Should I flash the original BIOS back ...
- ... and use Claymore/Eliovp's Mem tweak?
- ... or can I still use my modded BIOS with Claymore?
- Do i still need to apply the pixel-clock-patcher after installing a new AMD driver?


Thanks for any help!

One more thing. Think you have a bug with NVIDIA timings. When I  try to apply strap 1 to one card and strap 2 to another. But they both have the strap 2 as result.

Can you support TethashV1 (upgrade ethash)

1. Project description (pools and rteo parity modified node)
  https://github.com/tao-foundation/rteo


here's algorithm EIP-1485
1-1.  https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1485.md#4-real-implementation-for-fnv1a

1-2.  running pool lists
   -  1) teopool.tao.foundation
   -  2) teopool2.tao.foundation
   -  3) pool1.tao.foundation

1-3.  efficiency of algorithm compared than ethash
   - 1) more randomizing on MIX parts.
   - 2) simple more multiplication loops makes less hashrates 5~10% , compared than ethash
   - 3) simple more multiplication loops makes hard to overclock for the meet fpga / asic timing meets.
   - 4) more fair speed on cpu / gpu / fpga / asic .


It has upgrade ethash MIX parts, for prevent ETH-ASIC .

deprecated fnv0 upgrade to fnv1a

applied source patched things here.

2. teominer fork of  ethminer
https://github.com/tao-foundation/teominer

2-1. reference opencl code :  https://github.com/tao-foundation/teominer/blob/master/libethash-cl/kernels/cl/ethash.cl
2-2. reference cuda code :  https://github.com/tao-foundation/teominer/blob/master/libethash-cuda/fnv.cuh

2-3. patched ethash cpu code : https://github.com/tao-foundation/tethashv1
 
If you are interested on this, you can add easily, because small modification of ethash.
And, please let me know email me : cpplover@trustfarm.net

Thanks.

2 Claymore.
I think you should rework the way you do miner exit on gtx1080ti's with straps applied. I found a trick how to fix your timings and than run your miner without strap management.
It keeps high speed of modded timing and doesn't crash system on exit.

Ok I will restore settings at exit.

14.0 - 14.2 versions do not detect NVIDIA GPUs on mixed rigs (AMD + NVIDIA)

Install latest drivers or use files from "cuda8" folder (redownload v14.2 if you don't have this folder).

Good afternoon. Thank you for your new version. Will new features be available in the Linux version? strap ?

2 Claymore.
is it planned to add the Ubqhash algorithm for the UBQ coin in your miner?

[ustcstone]

any update about linux version?the windows version works great but my rigs are almost linux.....

Just read last 2-3 pages of the thread and you'll find answer.

v14.3 Beta:

- fixed BSOD issue with Vega cards.
- improved handling memory timings for Nvidia.
- "strap" option for Nvidia cards: added "-strap 4"..."-strap 6" options, they have less intensity than straps #1..3 so you can try to use them if you cannot use even "-strap 1" option.

Hi,

is the magic strap function Windows only? Won't work in Linux?
thanks

i am getting allways this error (Radeon RX 580 Series): ( no matter witch strap i use )

Try to install latest AMD drivers, something is wrong with drivers if you see "pci bus -126"...

- "strap" option for Nvidia cards: added "-strap 4"..."-strap 6" options, they have less intensity than straps #1..3 so you can try to use them if you cannot use even "-strap 1" option.

How to run on Windows 10? You can describe the settings.

Hello, I wanted to comment on a problem I have.
I own 7 Asrock Rx 570 8gb (micron) GPUs. By setting the GPUs in -strap 4 and overclocking, two GPUs make windows crash.
To avoid this, I omit those two GPUs "-strap 4,4,0,0,4,4,4"
I have tried different settings, but always hits windows.

It is rare that being the 7 GPUs equal (same make and model) there are two that can not do the Strap Timming.
Any idea how to fix it?

[kevinkuo1995]

Now I use rx 5xx and vega56 in same miner,but when I use the strap for anyone of them will freeze until I reboot

Without strap is fine for mine

Anyone have any idea why will make this happen or how to fix it?

Thanks for help

can we overclock when using "strap" or not ?

give us more details about this strap

wtf is straps on nvidia cards? Can you really change gddr5 nvidia timings?

[Elange]

Linux version 14 missing ?

Have heard of the eth pill? I believe it did the same thing but with the GDDR5X mem on the 1080/1080TIs. So why would it not work with regular GDDR5?

Strap 3 seems to work best for Polaris ?

Depends on memory manufacturer. For hynix MJR 2nd strap is better.
