anyone have any decent settings for CN-R on vega 56?

anyone have any decent settings for CN-R on vega 56?

Ref Vega 56 stock bios
1407 core  930 mem  850mv

--CL 17 --RAS 26 --RP 10 --RC 36 --RFC 248 --RRDS 3 --RRDL 3 --RCDRD 12 --RCDWR 5 --REF 15000 --FAW 13 --RTP 4

Hi, in my MSI Airboost Vega's Rig, --RP11 or --RP10 crash the cards !
Solution ?

I use TRM 0.5.7, config 14*14:BAB, (amdmemtweak --CL 17 --RAS 26 --RCDRD 12 --RCDWR 5 --RC 36 --RFC 248 --RRDS 3 --RRDL 3 --FAW 13 --RTP 4) + (15600 REF)

1407 Core  / 900 Mem / 930 Mv = 2100Khs Max
When i go up to 960Mv, many errors = 2170Khs

What is your best configuration for Vega56 ?
Thanks

it turned out at least someone changing the strips or timings on rx5700 to change the speed of mining up/down?

change stripe 1250 up to 2000 - not effect
may be drivers 19.10.1 not support this or miner?

Yes. please do we know what is the plan/are the thoughts/is the status for 5700 timings?
competitive advantage may be in not providing tools able to mod 5700 timings though

[liomojo1]

Sorry guys ,but timings for 5700 are locked and you can't do anything about it. You can change it on a tool but they will be refused by the hardware. Blame it all on AMD.

[shostt58]

its problem gpu 5700. or bios rom, or driver?

[Mstuksu]

I still have an r9295x2 in my AMD rig. Has anyone tried this on one of those power hogs yet?

Good day!

Are planning to add feature to  CLI version to control P7 (core control) and P3 (memory) values and Fan control states in .bat file

Thanx in advance

Hello guys !

I've got 6 Sapphire RX Vega 64 Nitro+ and I would like to knows if someone had test wich parameters is good for this card.

I'm using Claymore V15 for mining Ethereum (ETH) only

I've already test BuriedONE parameter in his video but I've got overclocking errors

Thanks !

I use the following for ETH on my Nitro 64s - maybe not ultra best, but close enough:

Code:

--RAS 28 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --RRDS 3 --RRDL 3 --REF 15600 --RFC 248 --FAW 14

for a couple cards w/ weaker mem chips/controller, i use a slightly less aggressive profile:

Code:

--RAS 32 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 15600

Thanks for your reply !

What kind of profil do you use in Wattman ?

Hello Guys !
I'm using some vega 64 and 56 with Samsung memory ( founder edition) and I would like to use them for ETH.
Do I need to flash Vega 56 with 64 bios ?
 I would like to knows if someone had some good parameters to share ?
Thanks

This is my 64 ref doing stable 49.4MH @1080MHz mem

56 is stable at 1050mhz mem
getting 44.5 mh eth using claymore

Look at hte ReadMe for TRM miner for some settings - I'm getting 49.4 mhs on my flashed 56 to 64 at 1050 850mv

Look at hte ReadMe for TRM miner for some settings - I'm getting 49.4 mhs on my flashed 56 to 64 at 1050 850mv

tried their weakest settings
after applying it and started mining again the hashrate increased to 47.6 mh but after 15 to 20 minutes the system always hangs
i have to restart it to start mining again and it says radeon settings have been reset
i do not think the card is working stable with additional modification

Hello pbfarmer !

Thanks for your reply !

What kind of profil do you use in Wattman ?

Nico

I don't use Wattman (or even Windows, honestly,) but basically I lock my core state to p0 (850Mhz) by disabling all states above that, while setting my mem clock to 1107 (p3).  Then set your mem p3 voltage to whatever is required for your card - should be somewhere between 800-850mv.

This should get you to ~50MH/s for a Vega64.

I suggest you get your vega stable at the highest mem clock you can reach, then run

Code:

WinAMDTweak.exe --current > current_mem_timings.txt

see what your default values are and improve from there
better if you'll keep the following: RC = RAS + RP and RAS = MAX(RCDRD,RCDWR) + WR

hello pbfarmer ...do u meant u r using hive os or some other linux based system.
can u just post a screenshot of your overclock settings.your explanation just went over my head.
please post if u don't mind.

I've built my own linux system, and it's kind of hard to screenshot the settings, as it's mostly done in text file full of hexidecimal values (called a ppt file). 

Here's the general idea though, illustrated in a windows tool called OverdriveNTool which many people use instead of wattman.  Ignore that it says it's a RX 590 - the idea is the same for a vega.  Also note, that every clock/voltage pair are disabled except the first GPU setting (P0) and last memory setting (P2 here, but a vega would be P3).

why do you think that you are changing the voltage of the memory on vega?
it's 1.25V on vega56 and 1.356V on vega64 - actually the reason to flash v56 with v64 bios is to update the mem voltage to 1.356

P.S. also in my experience setting proper phases make GPUs more stable (maybe it has to do with actual electricity supply and/or smoother silicon performance)
