I think that’s a bug in HiveOS; if you have ever had other gpu like rx580 in the same rig and had set DPM state for that one, then replaced the gpu by a Vega, the DPM state is still there.
You can do 2 things:
Restore that other gpu and remove it’s DPM setting, and restore the Vega afterward.
Or more easy, note down all your other OC’s (you have a print screen here already), then go to the Overclocking TAB and click the Reset All button. This will remove all OC’s so also the DPM state. After that, just enter the OC’s again which you have noted or print-screened.
Holy *** that’s a nice finding!
I truly love your experiments!
Yes, that is indeed pretty straight forward; but what makes decide TRM to choose e.g. 448 one time, and next time 472 or 592 as the gpu straps and oc’s didn’t change. @aminer also mentioned temperature; but it would still be interesting to know what influences it as the temperature is the only thing I can’t control (entirely).

haha I am just glad someone enjoys all the pictures I post 
Working on my “worst Samsung vega” today, and found something interesting…
GPU 3 here has been throwing invalids with every strap i’ve tried and all the way down to 960 mem, went back to the strap from the TRM guide and hit 24 hours with no invalids at 960. Slowly started changing each setting from the TRM strap to the levels I run on my best cards, and found what was causing the invalids was the RRDL?!
Stock Samsungs have a RRDL value of 5, TRM guide suggest turning it down to 4 but most straps have it set to 6 since setting this value to 6 increases hash by about 0.1- 0.2Mh
after 12 hours at 100%, changed RRDL from 4 to 6 and got 2 invalids in 90 minutes, using this
amdmemtweak --RC 37 --RAS 20 --REF 65535 --RRDL 6 --RRDS 3 --RCDRD 12
stress testing that value by only changing RRDL in my normal strap and pushing mem to 1027, 3 hrs so far at 100%
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 5 --RRDL 4 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12

Hello guys!
This is my AMD rig:
GPU 0 - Reference Vega 64
GPU 1 - Asus Vega 64
GPU 2&3 - Gainward Vega 64
GPU 4 - Gigabyte Vega 56
I’m ending the set up of the straps, so I dont post them yet, but there’s nothing special, just step by step and slow work. RRDL at 5 for all cards up to now.
I’m really enjoying this kind of job, Nvidia 3000s are more much boring! lol
But the only I don’t understand, its why there’s that big difference of temperature between both gainward cards, similar power consumption, and new thermal pads for both… 11 celcius is a world!
Any idea?

And then there’s the ICU…
This card is not working fine, so it was mining @ 44MH/s with no straps for the moment. With ss-silver straps now it’s mining @ 49MH/s and still stable.
amdmemtweak --RC 38 --RAS 26 --REF 21000 --RRDL 4 --RRDS 3 --RCDRD 12
It’s a reference GB Vega 56, and fan won’t work over 40%, so it gets so hot. I think I will try to connect the fan to the motherboard or molex, because with better temps i would probably be able to put decent straps.
This is happening since i clean up this oxide:
Hope dont go worse.
So thanks for the straps =D

i have on my 3 ref 56 same oc on all, with proper cooling i can run them mem1020 vdd815 core 1100

These gives around 55.4mh
Did one new ref card´s paste, i didnt had in hand any pads, only 1,5mm pad for the small chip that is a bit low on the board.
There was still factory seals, a virgin, thermal paste was hardened really bad, shame i didnt had 1mm pads, will open it again later. So after thermal paste and 2 small thermal pads, it was running with core around 62c and mem 73-4, now core 52c and mem stable 71c.
sneak peak to mining chambers if u want, take a look.
Show us your rig or rig´s!

Thanks again for this great finding!
For the purpose of testing, this morning I also lowered it to 4 on my 2 Vega’s that kept crashing in B-mode and you know what? Now already 4h30 up and counting!!
After 24h test I’ll start lowering their clocks and mems too so their temps decrease to the same level as the others 
Must test that 1027 too one of these days 
Nice!
I’d rather not post on YouTube myself, but maybe we could start a thread somewhere in the hive forums if it doesn’t exist yet?
Also curious about all your setups
When repasting the GPU/HBM I have noticed that when remounting the cooler, you have to really really tighten the screws or there can indeed be a big difference. I haven’t had as high as 11°C though, but had up to 6 to 7°C in the past which disappeared after repasting again and tightening.
Don’t know if your issues are related, but might be worth investigating.
First rig in video, dungeon´s is 6x rx570 ±180mh. PSU 850W.
Second rig is 7x vega´s 56/64 ± 430mh. 1600W + 750W.
Small on the floor is new, bought used mb for 60eur had all other components with 1x rx580 and bought 1xref vega56…that is still not ready. ±83mh 750W.
Fourth rig is 4x rx590 + 3x rx580 ± 220mh. 1350W.
When normal temps these produce about 930mh.
On vega and 5xx rigs there is H110 pro btc MB´s. 6x570 have some older asrock and "new"one is Asus something with 4x pcie without splitters.
Total from the wall is around 3,5kW.
Yeah, i understand youtube etc, thats fine, maybe just a photo would be good if someone want to share , it goes on the side with some random post

You sure? That’s about 61.4MH/s per Vega. Then you’ve found some amazing straps that you haven’t told us yet 
I’ll see what I can do

right…8x vega´s on that one 
@Smining570 thats sick
I just got these two little guys, the custom server box one looks cooler but runs cards about 2-3 c hotter due to limited spacing between the cards.
^ the bottom card here is the 64 with Morpheus cooler and noctua fans

wery clean, i love the box fans, havent found right size so ordered one floor fan for hot days. So in server box they run hotter, those are delta fans,right? must be really good rig that one, wouldnt mind to get one really nice
Ok, my turn now
I first started small in the garage; but there is not enough ventilation so it got too hot in there when I got to 13 gpu’s, so I moved the rig to the back of our house into a toilet which we didn’t use anymore 
The backdoor was always open to ventilate, even during subzero ambient temperatures 
Don’t look at the (non-existing) cable management 
On the bottom is my test computer for 1 gpu. I’m planning for a bigger test rig but lack time lately.
Then in the basement I created some box from old metal racks. The side panels can be removed for maintenance on the rig, and I have mounted 2 industrial fans on the basement exit, one for fresh air intake and one for hot air exhaust. I can make change their speeds depending on how hot it gets. On full power they consume 230W each and make more noise than the rig itself 
The 13 Vega’s run on an ASRock H110 Pro BTC+ mobo and are powered by 3 PSU’s totaling 4200W, but pull only ~2400W from the wall (or in B-mode even less, see one of my earlier posts).
I still feel I can improve it a lot, like maybe a dust filter and isolate it for noise and heat, but lack time

@oni Thank you for the suggestion of resetting OC’s I was able to get rid of the DPM
@ss-silver I added the tweak along with setting the VDD to 825 and I am still having no luck. Number of invalid shares has slowed down but its not stable… ie shutting down every 20 mins.
What should I be trying to get this thing stable. I will worry about increasing mh later on all my vegas
Unfortunately one of them died a lot during the night, the original 56.
But the 64>56 didn’t! (But as the 56 died a lot I don’t know yet if it keeps stable by itself this long).
I now lowered their clocks to 1050 but kept their vdd high. Will see if that keeps them alive.
that metal frame with fans is insane! 
mail man brought to me allso a bit bigger fan yesterday, but this your setup with doubble fans and frame that u can modify like that must be perfect for all ambient temps. Still trying to figure out best place for this exhaust
nope, both of them are dying again 
thanks!
unfortunately they don’t cool the ambient air; they just make sure there is more air flow, but if it’s hot outside, the hot air is blown over the gpu’s so I see their temperatures rising anyway. But the hot air from the gpu’s is also exhausted better, so overall it should be a better setup, but as mentioned above, when outside temps go >23°C I have to tune the gpu’s down to keep their HBM’s at 70°C max.
