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

[pr3fix]

i only get 31 mhs with one card but others only get 13 mhs, i switched driver to compute mode i have adrenalin 19.4.1, can someone help me

Who has the same problem, here's the solution.

Download AMD-Compute-Switcher and switch all the cards into compute mode, in one click.  

https://mega.nz/#!Qgl3EYxJ!_7Aes-JHrnhGpIl2v_3EwG6E_jAsV_gjyj-Eg3IFGkY

Getting started:
- Run AMD-Compute-Switcher.exe
- Read the message, on top you see "switch to compute mode" or "switch to graphics mode". Press OK if you see "switch to compute mode. - this happens if one card is not in compute mode.
- Reboot

[Claymore]

To enable compute mode on all cards: start miner as admin, press "y" key and reboot.
BTW, miner shows the note about "y" key during startup, but almost all people skip it

Hi everyone!

Correct  me if Im wrong. If i have already modded cards ( modded-straped BIOS), then i should use only -rxboost 1 option, and dont need to use -strap ?

And if Ill use  -strap i will crush the system ?

Best regards.

UPD. How mych speed do you get with rx 474 ?

The same question I have + what driver should be used to get the best performance? the blockchain (for modded) or one of the lastest one?

Latest one, i personally use 19.3.2 with compute mode switcher and atikmdag patcher.

Yes, right, many missed it.

So what about my question ? Any advice ?

please rxboost  - for nvidia )

Dear Claymore,
What is best driver for polaris vga?

Simplemining just implemented Rxboost on linux  

I am running Rxboost on ethOS (Linux), RX474 32.1mh/s , before 31.4mh/s

=========================

Hi Guys,
Why are my 8cards setups crashing? The rig freezes immediatly after applying the first straps. When i remove the rxboost 1 it works fine. I dont have issues with my 5 and 6 cards setup.
The cards are 8x rx580 8gb. with Asrock h110.
Using Adrenalin 19.5.1 and Claymore 14.5

Please HELP!

Ok guys, just tried -rxboost 1 on another machine with 6 cards on Asrock h110 pro btc and it crashed while applying the straps in claymore.
Seems li rxboost is not working on Asrock H110 pro btc??

Please HELP!

It's rather simple adjustment that I discovered a few days ago, so it's easy to clone it It works for old AMD cards too, so "-rxboost" option will also support old cards in next update.
The real magic is to apply straps on latest Nvidia (Turing), Nvidia protected these cards from such tricks, I have a solution for it too, but need some time to implement it properly before including into miner.

What rxboost actually doing?

It increases refresh interval: https://en.wikipedia.org/wiki/Memory_refresh
This setting is not included in AMD straps so you cannot change it with straps.

-rxboost 2-100 means 100 - max, 2 - min?

Any idea about low hashrate? Rxboot and strap no used, card are bios modded. Compute mode is on. Driver is 19.5.1. Claymore is 14.5.  6*rx480, aprx 4.8 Mh/s each. On claymore 12.0 and old blockchain driver was 30 Mh/s

So you can use rx boost and strap command ?

[evlo]

I think nvidia part of the miner is really beta ,
multiple gpus crash with strap 0 intensity 0, +0 mem while before took +700 mem with ethminer or phoenix
some gpus with straps crash after 46hours of mining - this I think might indeed be to much OC, but still I would expect it to crash sooner
but really I think it is some driver (DCH on rigs with most issues) or even just NVML issue (again DCH seems to have differences in NVML) - well thinking of it now, issues on rigs without DCH drivers are kinda manageable and be indeed cause by straps or too much OC, but on rigs with DCH it seems to just not work correctly
Of all the nvidia rigs only one just works after applying straps, while mostly nvidia gpus are same with same memory in all of the rigs.


I dunno maybe i just don't know how to do things, but my amd rigs use straps (in bios) and work 100% stable. Some autotune for nvidia or something would be nice.

Maybe a way to know memory errors like hwinfo does on AMD? But AFAIK NVML does not report it for consumer cards, so some hack possible?

Please don't get me wrong - I'm glad that you are doing actual improvements after so long (timing straps for gddr5 nvidia)! Just as it is such a new thing for general public it may need more ... support?

Who achieved what speed on the claymore 14.5 on maps 1060 6gg (Samsung, micron).
I have Samsung GPU0 26.806 Mh / s, GPU1 27.239 Mh / s, GPU2 26.377 Mh / s, GPU3 27.224 Mh / s, GPU4 27.171 Mh / s, micron GPU5 26.300 Mh / s, -strap 1 -sintensity 80
PO, core 1480, memory 4644-4706-4551-4704-4698 micron 4532, curvia 812v, PL80, firewood 391.24. (On new ones, the speed is 1-1.5 Mh / s lower). Who will share their settings.

Microns strap 1,100 - 25.6 on best cards (+640mem), while keeping <70w per card (by undervolting, but I guess it is now equal to PL70).  Drivers: somee recent ones, i think 430something
Did not get to samsung jet as I still have lot of stability problems.

Do you think, that maybe using PL instead of UV there is better stability with straps?

VFL is always better than powerlimit.

Excellent results on my MSI GTX 1066 ARMOR (Samsung +50 core clock +850 memory clock)
it was 24.5 now 26.8 MH / s
How can I disable the test mode of Windows 7?
