v14.0 Beta:

- Windows only: added ability to apply optimized memory timings (straps) on-the-fly, without flashing VBIOS, up to 20% speedup compared to stock BIOS. Currently only Polaris cards are supported, other cards will be added later.
Drivers 18.x or newer are required. Best straps for Ethereum are included. Check "-strap" and "-driver" options for details.
- Windows only: added temperature/fan/clocks management for Radeon VII.
- a few minor bug fixes and improvements.

Thanks for all the miner work you've done!

If I have already flashed the vbios of my 580 and 570 cards, do I need to restore the stock bios before attempting the custom -straps in the command line?

Claymore, I know I may be asking a lot here, but just in case it's not too much additional effort... The Radeon Pro Duo is technically Polaris. It's got Samsung Mem (16GB on each GPU); two WX7100s/RX 580s.
Was hoping your straps would work without having to try bios flashing the master and slave gpu bioses, but the miner instaquits it I run as admin with -strap 1. If I don't run as admin, miner runs fine, but with no straps. Believe it's related to errors reading the boot configuration data.
Driver is latest Pro Driver, 19.Q1.2. Have used the AMDMemTweak CLI from Eliovp, and it works, but would like to try the straps you are using in your exe. Others messing with AMD workstation gpus may get some good here too! Thanks!

Check the log file for details. Or create "config.txt" file with options and right-click EthDcrMiner64.exe and select "run as admin", it must work. Or start "cmd.exe" as admin and start miner from it to see what happens, miner cannot close without any messages.

Claymore, many thanks! it worked with the config.txt file, just not the start.bat file.

So, without disabling secure boot no chances to run with straps, right? It's not good...

Do you really need secure boot on your rigs?
I could sign the driver, then some people will use my miner as malware, as always, then some AV will mark it as virus, then the certificate would be revoked... No way.

I didn't need SB on all my rigs. But on some of them I work and SB can't be disabled on them... That's why I ask...
You can make separate exe-utility for installing driver and sign them. Miner can use this tool for installing/uninstalling driver and even if miner will marked as virus, driver installed by separate tool with sign will not revoked!
Just think about it, please. I'm sure that it can solve many questions in future.

And another one question: you made memory straps by yourself? Or you take it from somewhere? Can you share this straps for us, so we just flash it on our bioses. Those who can't use driver?

P.S. Some time ago zawawa (he maked GGS miner) can apply memory straps in his miner without any drivers on the fly... So it's exist a way to do it so...

How much hashrates for ETH were you able to pull out of 580 8gb cards with these new straps?

Not huge numbers, something about 33MH on RX480 8G Samsung with stock BIOS and voltage.

Any plans to implement this feature for linux version ? (as far as its possible)

I'm not going to do the this trick in Linux, sorry.

Secure boot didn't allow to load unsigned drivers with UEFI bios.
I tried to run miner with admin rights but I got error:
In log:
23:39:57:796 4e14 Driver is not installed! Trying to install it...
23:39:57:854 4e14 Failed, you must run miner with admin rights.
On screen system error message appears before "Failed..."
"Value protected by secure boot policy and can't be changed"

Oh, you are correct, I completely forgot how it must work.

until memory clock will go idle (in a few seconds), then enable GPU again in the miner, new clock will be applied after that.

It will be the same as restart miner? I remember that at startup miner try ti find best dcri value, so trick with enabling/disabling GPU with new memclock may be not best way, because optimal DCRI for this card with new memclock may change?
Or optimal DCRI may change only if CORE clock have changed?

It depends... Anyway you can use "+" and "-" keys to change dcri to see if they are good for new clock. Or just set fixed -dcri, find highest stable clock and then find best -dcri value for this clock.

If you spend so much time, how is the fastest way to found the best strap/mem clock?
Is there way to found max mem clock without restarting whole miner? As I remember, when I overclock memory, hashrate go up only after restartminer... so restart miner every time is slow... maybe you found beter way for fast applyong new memclock and see new hashrate without restarting miner?

I spent much time in attempts to implement this trick, not in overclocking. Anyway, use WattMan or AfterBurner for overclocking. Put hdmi dummy plug into card and it will apply new clocks immediately. Or set new clock and disable GPU in the miner ("0" key for first GPU, "1" for second GPU, etc) and wait until memory clock will go idle (in a few seconds), then enable GPU again in the miner, new clock will be applied after that.

Without your driver straps can't be applied?
P.S. Why 14th version? There is no 13th...

Secure boot is not related to the driver. Miner will set "Test Mode" in Windows to use unsigned driver.
I don't like "13" number so I skipped it

I think it's a good idea to quote Readme about "-strap" option. In general, you use "-strap 1" value and then try to overclock memory to see the highest stable clock and hashrate. Then you can try "-strap 2" and do the same. After these tests just select the best strap index and clock. At the same clock "-strap 4" will show better hashrate than "-strap 1" but it will not support very high memory clocks, so final hashrate after oveclocking can be lower than "-strap 1" with very high memory clock.

Code:

-strap applies specified memory timings (strap). This option is available for Windows only and requires AMD drivers 18.x or newer (most tests were performed on 19.4.3).
Currently only AMD Polaris cards are supported, support for other cards will be added later.
Miner has built-in straps database, all straps are separated by memory (4GB or 8GB) and memory type (Samsung, Elpida, Hynix, Micron).
Straps are sorted by intensity, i.e. "-strap 1" supports higher memory clock than "-strap 2", etc. For the best hashrate you must also set high memory clock, so "-strap 1" is a good start point for tests.
You can specify just strap index, for example "-strap 1" will apply first strap from database for all Polaris GPUs based on GPU memory size and memory type, miner will show full strap name detected.
Or you can specify strap directly in format "POL8S1": "POL" means Polaris, "8" means 8GB, "S" means Samsung memory, "1" means index.
Zero index means default strap from VBIOS, i.e. no strap is applied.
You can also use "@" character after strap to specify memory clock, it works like "-mclock" but overrides it, for example, "-strap POL4E2@1900".
You can also specify values for every card, for example "-strap 1@2100,POL4H3,0".
If strap is applied, miner will return old strap and memory clock when miner is closed.
The best approach to find best strap is to set "-strap 1,0" (it sets strap #1 for first card and no straps for the rest of GPUs) and then raise memory clock to see what clocks and hashrate you can reach.
Then so the same for strap #2 etc.
You can also specify raw strap string (96 characters). Note that single option value means that this strap is applied for all GPUs, use "0" to apply strap on single GPU,
for example "-strap 0,1@2200,0" applies strap #1 and memory clock 2200MHz for second GPU only.
NOTE: if specified strap fails, Windows is crashed. After reboot default timings are restored and you can try some different settings.

Forgot to mention: this version uses straps that were provided by Eliovp, they must be very good.

So yeah i have the same issue running driver 19.4.1

It did not work for me with the start.bat file , just closed when running admin rights...
Changig config.txt file and then running the EthDcrMiner64 did work just fine...

thanks a bunch mr Claymore!

It is an improvement, but unfortunately I'm still experiencing issue with Chinese directory names.

Sorry, I did not have time for it, though I checked this issue and confirmed it. The reason is that the miner does not use unicode, it will take some time to convert all paths and filenames to unicode strings.
