That tweaking, is it fixed per profile number (so it will be always the same depending on the number)? Or will it run some tweaks in the background to find a sweetspot?

For the same gpu it will be the same, yes. There is no auto tuning.

Alright, just wanted to be sure Thanks!

I don't think it is good idea to mix miner and memory timings optimizer in such manner. User should understand what benefit he/she gets from miner optimization and what benefits from timings.

I think Elio's utility will help to understand what timings you apply when "tuning" ))

Nevertheless, thanks for hard work, I'm still using your miner for older cards. But for vegas teamred is the king now.

Hi ,i run SRBminer ver 1.83 with X-cash ,and i got 460h/s with rx 570.rx580 .It correct ?

I think you are wrong, the user doesn't have to know how things work, the user just needs to get out as much as possible from his mining hardware.
The curious ones who want to learn how stuff works will learn.

Also 1% of people want to know how the various timing parameters work, the other 99% just wants everything prepared so they can copy paste. Sometimes even that is too much work for them.
And i am glad you shared what's your favorite miner, or who's da king with me, thank you

Does your miner return back stock timings when it exits? Sorry, no time to check it by myself on the rig

Yes it does, it returns the ones that were active before running SRBMiner.

I have a mixed rig of two RX 580 8 GB, two Vega 56 flashed to 64 and a Radeon VII. I tried SRBMiner 1.8.4 with driver version 19.4.1 & 19.4.2.

The hashrate of Vega 56/Radeon VII is very low, ~900 H/s but RX 580s is hashing at the same 900+. Have tried with and without memory timings aswell as with and without tweaking settings. Something is very wrong with my setup as it seems? But with another miner it mines very well.

For the sake I tweaked all the cards for very high efficency and low clocks like 1150 MHz for Vega 56s and 1540 MHz for the Radeon VII if that's making any sense. Memory at 900 MHz for Radeon 56 and 1000 MHz for Radeon VII.

There are 5 (6) profiles, where :

0 - no change, uses your original settings
1 - light tweak
2
3
4
5 - max tweak

You should find separately for every gpu the profile it can handle, and set it in gpu_conf or cmdline.

Is there any way to see if tweak profile was set successfully from config?

I made this config.txt:
{
"gpu_conf" :
[
   { "id" : 0, "tweak_profile": 5 },
   { "id" : 1, "tweak_profile": 5 }
]
}

But I don't see any differences in hashrates and when I press "+" it says it switches to profile 1, so it looks like it was using profile 0 in the beginning.

[doktor83]

Here are some numbers from my Vega56 with Hynix memory, just pushed mem up to 940mhs and P7 to 925mV.

Applied only "tweak_profile" : 5 to every config, nothing else changed in config.

Before tweak / After tweak ~ increase in percents

v4:  1854 / 2128 ~ 15%
haven: 1800 / 2000 ~ 11%
turtle: 15630 / 18440 ~ 18%
mox: 3845 / 4525 ~ 17%
fast2: 3604 / 4111 ~ 14%
conceal: 3726 / 4065 ~9%
litev7: 4386 / 4965 ~13%
xcash: 958 / 1106 ~15%

you should really check out the readme or the first page , there are examples on how to use gpu_conf

[impynick]

I understand the memory tweak only applies to Vegas;

Will it be possible to apply the tweak to the rx series in the future? Thanks

I read it and I took this piece of config above from there. Also tried this: "use the "tweak_profile" parameter on top of config so the same profile is used for all cards":

{
"tweak_profile": 5
}

Also no visible change in miner's behavior. That's why I decided to ask if there is any way to check if tweak profile is applied on miner start.

Well what you pasted there is not from any of my examples, sorry

You need to make a full config file, not just some partial stuff. And yes, there is a notification on miner start that it applied profile X to gpu bus id Y.

Here's a minimal config file that applies tweak profile 5 to every gpu and uses miner auto settings.

Code:

{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"tweak_profile" : 5
}

tweak work only on vegas?
4xx 5xx dont work?

[lttsi]

Anybody give me speed X-cash  (rx570,580x ) pleas .
My rx 570 4g run ~460 h/s with core 1100/1950 elpida timming

V1.8.4
- Performance increase for Vega56/64/Fe/Vii up to 15%!
- Minimum for 'main_pool_reconnect' is now 60 seconds instead of 180
- Added new cmd parameters: --disabletweaking, --cgputweakprofile
- Added new config parameter: tweak_profile
- Minor bug fixes


+ Yes, you read it right. Performance increase on ALL algos on Vega56/64/Fe/VII up to 15%!
A new parameter 'tweak_profile' was added, which if used can significantly boost your hashrate. There is section about this on the first page, but in short:

There are 5 (6) profiles, where :

0 - no change, uses your original settings
1 - light tweak
2
3
4
5 - max tweak

You should find separately for every gpu the profile it can handle, and set it in gpu_conf or cmdline.

VERY IMPORTANT :
1. Miner must run with administrator privileges [right click on SRBMiner-CN.exe->properties->compatibility-> check 'Run this program as an administrator' option-> click OK button
2. Don't apply any memory timings with ElioVP's tool before running miner
3. Don't start testing/tweaking with your highly optimised PPT and ODT settings - because it is probably optimised for a miner/algo combination.. Start with stock settings.
4. Be patient, it takes some time to find settings optimal for your gpu/rig

Tweaking is enabled by default, and can be used on supported devices.
If you want to disable it use the --disabletweaking parameter in start.bat

It can't get easier to use, just use + and - on your keyboard to move between the profiles.

Examples on how to use it can be found on the first page.

Special thanks goes to ElioVP for sharing the offset of the timings position.

On my two rigs the WinIO64.sys blocked usage of WinAMDTweak.exe by blocking the loading of EIO.dll. This persisted even after rebooting. The only way of deleting the file was by booting into safe mode and deleting the SRB 1.8.4 folder.

Tweak is for vega...,doesnt work on 4xx/5xx

Winio gets started/loaded on demand when miner starts. When miner is closed Winio gets unloaded but it wont get disabled until windows restart. After restart it won't be active so you probably ran miner again after restart, that's why you could not delete it.
