So i just released both windows and linux cli with a ton of timings exposed.
Be aware, i exposed them, i made em almost all writable but that does not mean that you should write to them ;-)
Getting BSOD's is a great learning curve  Grin
Please also check comments in the code.....

Just so you know, you can yet again improve speed on Polaris  Wink that's all i'm saying.



Hope there'll be some juicy way to tweak GDDR6 timings on RTX cards... Smiley

I'm not going to release Nvidia mem tweak, so don't count on it  Cheesy


Cheers
maybe a little hint for Ploaris?just there are so many parameters,and i try to change same but either nothing changed  or dead GPU....

Hah. I'd rather have you release them than your good friend Ohgoda*****. After all, I'm sure she'd be all over them and dying to claim them as her work...

Well, i made the decision a long time ago to never ever release this for several reasons that are absolutely not important Smiley


But i don't mind annoying you guys with some screenshots Smiley

 Cheesy

well done, but i have problem to running cli version, the error message was
"
C:\Users\3\Desktop\amdo>WinAMDTweak.exe --current
Failed to load EIO.dll"


how to fix it, thanks

you need to have the two dll's in the same directory as the amdtweak tool and that will resolve that. they are built in the download.
I have done that

I had the same thing happen with the newest release. The previous version works fine for me.

Hi All! I'm sorry if it allready asked...

Please, say who knows - does MISC3 (MR4) RAS parameter affectes on stability? Or something else? And how it can be changed in vbios? I didn't find this param in Polaris Bios Editor...

Been testing Lexa RX550's (2gb elipida) with this tool. (To get them running with amdmemtweak linux cli version you need to add
Code:
(dev->device_id == 0x699f) || // Lexa [Radeon RX550]
to IsRelevantDeviceID.


Starting hashrate was approx 529H/S with TRM 1930 MEM, 1130 CORE.

I lowered RFC to 82 (crashes at 80), and messed around with raising REF. Running at RFC 82 REF 50 gives around 545H/S.. which is a nice increase.

Cards also seemed stable at REF 100, and this got around 549H/S. How high can REF go? Well turns out no higher than 150 with my cards at least.

Seems like there is even more room for improvement with these cards... I will continue to experiment. I noticed someone selling a BIOS mod that claims 650H/S on these cards, so that seems like a nice target (if it really exists). Am I correct in saying that REF can't be changed with a BIOS mod? so this 650H/S bios mod (if real) must have gotten the increase without using REF?

Thanks for the tool, hopefully will report back with better hashrate increases for these cards.

thanks , it work well now, can your support device id "1002-699F" which was called lexa in cli version, I have checked, it was not support while the gui version was support

win cli version how to add support for  0x699f  Lexa [Radeon RX550? the other question, 1930 core? is it 1130? I do not think the card can do with 1930 core?

I have some rx550 cards. I have baffin 8cu cards. They are soo efficient
I have managed to get up to 560hs with  1930 memory clock.
Maybe some of the new parameters in new cli version will push it higher.

Ah my bad, yes I meant 1930 MEM, 1130 CORE. OOPS

Not tried the windows version but it also has a IsRelevantDeviceID function (https://github.com/Eliovp/amdmemorytweak/blob/master/win/WinAMDTweak.cpp line 644). You should be able to add (dev->device_id == 0x699f) to that function.

Hello guys !
does anyone know how to disable auto-tune on phoenixminer ?
Because even with the parameters below given by @Zorg33 i got phoenixminer reboot regularly which is painful.

Weaker Vega 64 or flashed 64 (Samsung) - use if lucky timings aren't stable:
--CL 19 --RAS 30 --RCDRD 12 --RCDWR 6 --RC 44 --RP 13 --RRDS 5 --RRDL 5 --RTP 4 --FAW 18 --CWL 6 --WTRS 4 --WTRL 9 --WR 15 --WRRD 1 --RDWR 18 --REF 17000 --RFC 248

So until finding the sweet spot for my vega 56 flashed to 64, i just updated the REF to 17000 for which i get 47+ mhs.

Thanks in advance for your help.

Hi. Thanks for info on Lexas.
I have 2 Lexa RX550 together with 4 Baffin cards but I have no clue what parameters to use on amdmemorytweak/Teamredminer on linux.
Same for a RX480s rig/Claymore on linux. No idea about parameters neither.
I am only using the tool with 3 Vegas I have and it runs stable/Teamredminer again on linux. A lot of options and recommendations for Vegas on this thread but nothing real clear for 550s or 480s and I follow the thread for quite a bit of time.
Can please somebody give me some settings recommendations to get me started?
Help appreciated
Thanks

Congratulations on your work! Thank you for sharing this with ordinary mortals and crypto enthusiasts.

I invite you to beer and grill.  Smiley

How can I import the values automatically after restart?

There are good instructions for Lexa 550's in CN_GENERAL_TUNING that comes with teamredminer... but with the latest version of TRM it autodetects the best setting (L4+3), at least with my cards.

With the latest TRM and decent straps (PolarisBiosEditor/SRBPolaris) for elpida you should get 530h/s. Boost REF to 20 and you'll get 545. Core 1100, Mem 1950

You can also use a tool like OhGodATool.. the original was taken off github but forks of it still exist.

Hi, thanks for your answer.
Anyway, I meant values settings on Amdmemtweak not TRM.

You do mention :

                         [end quote]
As I said, I have not seen yet amdmemtweak example commands for RX550s or even RX470,480s, 580s. A lot for Vegas though and I understand it's where there are significant advantages.

Can anyone share amdmemtweak examples for RX550s and 480s?
Thanks

Hello,

I was wondering if it is possible to under volt my AMD cards using AMDMemTweak?

I normally under volt using OhGodATool but it seems to have stopped working on the newer AMD drivers (No longer applies any undervolts but still applies other OC's).

If I can do that with this tool that would be very helpful.

Thank you.

Is there a way to apply the same settings to all GPUs on the GUI version?
Right now I'm using the import button to apply each GPU.

Curious to see whether the new NAVI Gpu's will be moddable at all.
Tweaking GDDR6 could potentially yield some really strong results.

I'm sure eliovp would be right on it and share with the community, right? Right?...
