my rig draws 1.6kW so i need two psu-s.

diffrent breakout boards didnt work, so i got in touch with my fellow miner who had same brekaout board and now its fine

tnx for the answers, i have these to breakout boards, one has sync connector(floppy), one hasnt because has auto feature:
- This Breakout Board Adapter built-in Sync ON / OFF switch:
- Retains its state - Switch the button to A, if mining rig suddenly loses power, the PSU will start automatically when power is reset.
- Sync ON / OFF - Switch the button to B, the main power supply and the secondary power supply can power ON/OFF simultaneously.

so I should put brekaout board that has sync floppy connector at main PSU and other one that has auto sync at 2nd PSU?

these are the brekaoutboards:

Hi,

im trying to use this mbo + 8gpus with two 1200W HP server psu-s.

GPUS 1-4 are powerd with first PSU, GPUS 5-8 are powerd with second PSU.

My question is how do I connect 6pin pcie slots to power MBO?(maybe first two 6 pin from first psu, and 3, 4 and 5th 6pin mbo from second psu?)


Tnx for answer.

tnx for replys guys

Didnt create a softpowerplay entry in my registry, ill give it a try.

i was wondering is there a way i can just input straps for each of my vega gpus in teamredminer command line without using amdmemorytweaker?

crashed my windows and had to reinstall, clean installed win10 but now i cannot run amd memory xl, every time i turn it on it says it has to go to test mode, i click ok..than it says:

     An error has occured setting the element data. The value is protected.
     Succesfully activated test mode.
     Please reboot your system.

Reboted couple of time, every time its same, cannot run it.
Read somwhere i need to delete drivers in system32, so i did, deleated AMD folder, also used DDU for uninstalling, and still same error appears.

Tried older driver 19.5.2. also same thing, no luck.

Any help/tips?

Ankaro,

tnx for the answer, i hope some of devs answer your question about FE support in this tool.

I have one more question about autostart, is there a way that this can be done just like in overdriveNTool(much more practical) where you just autostart profiles with .bat for each of gpus(no need for reg powertable stuff)


example of input text in .bat

OverdriveNTool.exe -p0myProfile -p1"Profile 2"
In this example application starts without gui, then sets "myProfile" to GPU with id=0 and "Profile 2" to GPU with id=1 and then exit.

hi, i am not familiar with FE, but this is excatly what im searching...

i have 3 difrent vegas in my rig, V56 hynix, V56 Samsung, and V64

how do i put indexes for each of my gpust to apply autostart settings, also can someone please write down how do i put power states on and off, and change voltage(also autostart command)

for example:

cd C:\Miner\Apply_Mem_Tweak
timeout /t 1
WinAMDTweak.exe GPU1(samsung) (--CL 17 --RAS 35 --RCDRD 16 --RCDWR 12 --RC 44 --RP 14 --RRDS 3 --RRDL 5 --RTP 5 --FAW 20 --CWL 6 --WTRS 4 --WTRL 9 --WR 16 --WRRD 1 --RDWR 17 --REF 17550 --RFC 317) P1-P6 vcore off, only P7 at 900mV, GPU CLOCK 1100, same for memory mcore and mclock, GPU2(hynix) (--CL 17 --RAS 30 --RCDRD 16 --RCDWR 10 --RC 44 --RP 14 --RRDS 3 --RRDL 5 --RTP 5 --FAW 22 --CWL 6 --WTRS 4 --WTRL 9 --WR 16 --WRRD 1 --RDWR 17 --REF 15200 --RFC 317) P1-P6 vcore off, only P7 at 900mV, GPU CLOCK 1100, same for memory mcore and mclock, and so on for each of my gpus...


tnx in advance

Hi all,

until now i have used overdriventool for setting up clocks on my amd cards - when rig restarts to windows(i use autostart profile for overdriventool with .bat file), but now i got few vegas and would like to use amdmemorytweaker for v56/v64 with hbm timmings but dont know how to setup autostart .bat file to inject timmngs for amd memorytweaker, can someone please link or write down short guide(step by step) how to do this in win10.

Also i have been reading this thread and it seems to me very confusing(many combos) for hbm timmings, is there like some proven timmings for v56 samsung/v56 hynix/v64samsung that work out of the box without crashing?, i mean i dont care if i have 1-2 mhs lower hashrate, i just want good starting point that is crash free but gives higher hashrate than default factory timmings.
Been using settings/timmings from TRM ethash guide but they are not that stable

tnx
