Hello In this video I will show you my PowerPlay Mod
Fist I will show you the settings you need to choose
You should set the memory to the max you can
but every card have a little different HBM so some do more and some less
My cards can do 1105mhz without no issues so I will use that
This is something you need to check yourself before using this mod
Also please note that this mod is not meant to be used for playing new games
They would most likely crash.
I can play some games even while mining with this mod but not at max settings
Also you would have to use powerlimit 50% to play a game with this mod.
In this video I use the AMD Blockchain driver there is link to download in description of this video
Now to the setting used.. You have to set powerlimit +50% initialy or your memory will most likely not overclock
It is because of very strict power limits
For example powerlimit +50% on my liquid cooled card is about 550W
but not with this mod ofcourse with it powerlimit +50% is about 100W
thats why you need to initially boost it if your memory doesnt want to overclock
once you start mining and you see that your memory is overclocked and stable you can lower powerlimit again
Now you can see that I am mining at 1042mhz core clock and 1105mhz memory clock
Cards are undervolted and very power restricted right now
I cant tell now much these card consume right now because I dont have power meter but there is almost no heat generated by my pc now
but its definetly many time less than I could do with stock setting or stock powerplay provided by AMD!
Most tools dont work very well with the blockchain driver so its very hard to modify anything
But this mod work absolutely flawlesly with almost nothing required to do by user…
Now as you can see in this video Iam not hitting 44mhs but its because I am using 2 monitors and recording both gpu are in use by other programs than just the miner
normally the hashrate hovers between 43-44mhs very stable
I will put a link to description where you can see my statistics how I mine with these cards on ethermine.org
By their settings the cards should be limited to about 40W each but I think they use most likely like 55W from wall the way I use them in this video
As you can see the clock speed on both memory and gpu core is absolutely stable and heat output by core is minimal
Core temperature equals temp of liquid coolant used in gpu
the liquid is heated mostly by HBM and thas what you should look for.. HBM alone can be very efficient
the gpu core runs at lowest possible voltage to be stable and to keep stable clock speed at levels that does not affect your gpu mining capabilities!
As you can see the clocks are absolutely stable!
If you want this mod send me a message through this youtube channel
You will have to donate me with some ETH just anything 2 dollars maybe just to appreciate my time I spent making this 🙂
If you mine with VEGA at 150-250W this will save you lot money even with just one card.
Also there will be no bios mods because its not editable so optimalization of power play is the best way to make vega efficient
I dont think that there will be better mod available anytime soon if any at all
Also I am looking for someone with power consumption meter so I can verify the power draw if you have it and can make a video please send me a message!
If this mod works as intended there should be 0.8-0.9 MH/W which is absolutely insane and it would put VEGA as the best eth miner ever!
Nvidia cards have efficienly around 0.2-0.3 MH/W !
I will make second video and upload it within few hours as a proof
In next video there will be 10min footage of miner that is 4-5 hours runing and stable
some people might say that this video shows only first 10 minutes of mining and then anything would happen but cards are very stable
My cards are runing fans at 500-650 rpm and never hit higher temperature than 58C!
fans are barely spinning but I have to point out that they are on liquid.. its the Sapphire liquid edition
The rest of this video is just more screen time of miner and I am showin more gpu-z stats and amd wattman stats
Just to show how stable it is..
See you soon in next video!
