AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly

[Mashy81]

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 core, 1750 mem.

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.

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.

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?

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.

Hi,

On Ubuntu how can I overclock mems for a Rx580 8Gb?

Thx in advance

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.

Anyone use this on an R9 380 4G? I'm curious how far I can push my results but I don't have the slightest clue where to start with all these terms...

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

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

I invite you to beer and grill.  

How can I import the values automatically after restart?

Thanx

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.

[darman]

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

You do mention :

'...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...'
                         [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
Armando

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.

[dragonmike]

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?...

BIOS is locked like vegas, no reason why timings should not be modifiable over register space unless AMD has caught on and locks out this in user space.

Either way NAVI will perform exactly the same as Vega 56/64....memory bandwidth is the same GDDR6 will just perform slightly better due to tighter timings over HBM...major thing will be power savings over vega

GUI version. After rebooting the PC, how to apply the profile AMD Memory Tweak (which is saved as .xml)?
Created such a BAT file (c:\AMDMemTweak_GUI_Version_Beta6_x64\AMDMemoryTweak.exe -550H.xml) not applicable

It's not work this way. Run with --help command.

What refresh rate do most people use for an RX580 nitro+ 8gb?

Edit: Looks like 30

[bobymoore]

Guys please a vega 56 hynix settings also p6 state? Same with p7 or lower general....

What I did (lazy route) - looked at defaults, ran claymore with rx boost and saw those. Did some tweaks here and there. For the RX580.. maybe Vega could work too

[Ferdous Hossain]

hi,
I just don't understand the parameters. How can I mod it? Any guide?

Is there a way to apply raw memory timing strap(96 character one) like claymore does?
I'm using A RX 580 4gb sapphire nitro+ on windows
Thanks

[iRonNuke]

Anyone have great timings available for Vega 56's at CNR?
