No wonder why your profile trust is -2

Yes Samsung memory are amazing performance also on RX5600XT.
From experience any GPU could be with samsung either micron , even same box from factory have got half samsung half micron. Its lottery

Didn't have any difference over 6000

Yeah you can get MSI unlocked bios here also. https://youtu.be/tvmutIkbNIs
But what i have noticed you can flash this even on different brand and it will be working.

Do I have to put the old bios of my card, to unlock? I'm little confused here, sorry

Yeah the latest BIOS are locked and cannot mod the timings. Igors lab bios editor doesnt work properly on latest bios

Here are some modded bios for RX 5600XT , you can load these bios on different GPU brands https://youtu.be/tvmutIkbNIs

What i have noticed, Samsung memory GPUs are great for power consumption.
This 8GPU rig does 450mh/s at 1080w from the wall. It is in closed case , because of the high efficiency fans case itself consumes 130w.
So total for 8xgpu is 450mh/s @950w, which i think is great.
These cards are MSI mech RX 5700XT , i know many people complaining about mem temps on these - but look what temps. i have.
Same rig with same cards with Micron memory uses 300w more.

Yahh you have to look for older BIOS as the bios editor for latest BIOS doesnt work properly as the bios is locked.

No difference its just a random number.
When was testing increased numbers every time and felt like over 6000 there was no speed increase.

Have you tried to push core clock to 1400-1440?

Timing Bios mod for AMD cards is nothing new for increasing performance on Ethereum mining. Lately also available for RX 5700 graphic cards. Most simples is just applying 1500mhz straps down bellow, which increases performance by roughly 10-15%. But there is more to that, i was playing with the rom files. And figured out that editing Dram 12 timing also increases performance for mining ETH.
Mining is basically competition whoever can do most efficient. And you want to rigs run as efficient as you can.

So the steps are following to increase another 1-2 mh/s on top of your 1500mhz strap bios mod.

1.By default 1500mhz and down bellow DramTiming12 is set to 2850 and on some cards 2945.



2. You need to edit this to at least 6000 in (1550mhz,1750mhz,1800mhz,1875mhz,2000mhz). Some gpus timing starts from 1500mhz it really doesnt matter which bios you have. I tried both of these and seems like it is working just fine.





3. I have tested this on Asus Strix RX5700XT and also Gigabyte RX5700XT




What i have noticed your cvlt and mvdd also has to be low as possible , my cvdd was set to 760.

Im sure there is more to it and we can increase more performance by adjusting these timing. This process is very time consuming, and im sure people will find how to adjust more of this to increase mining speed.

Original post for full size images.

Only way to mod RX 5600XT i have been successful by modding  same manufacturer bios on it but different series.
Some bios are slower then others for RX 5600XT
On sapphire pulse which was stock bios max hash was 40mh , then used Sapphire pulse BE bios and got the hash up to 43mh/s
Like the timings editing really doe not work, it bricks the bios. It makes me think that we need different tools for editing.

Yes but the problem is you need very cheap power for this to be profitable. Because there is a lot of 4gb GPUs on ETH and if it will be profitable to mine kapow then all these gpus will mine it and kill the profit. If you know what i mean

Yeah you can make from them really value starting gaming pc. Or just mine some speculation ****coins
Selling will be real challenge when when all of these will hit market.

So Ethereum mining is very interesting. There is this thing called DAG file, which is processed in mining. Basically it is a file which is been loaded onto graphic cards memory. As ethereum block-chain size grows also DAG file size grows. Precise exactly 30000 clocks which is roughly 100hours. Current DAG file size at the time of writing this post is 3.78gb.

So how does the DAG file affect mining?

Graphic cards usually comes with memory size 2gb,3gb,4gb,6gb  and so on. This means if the DAG file is bigger then the memory module size on graphic cards , you simply wont be available to mine with your graphic card. If your GPU memory is bigger then DAG file ,you will be available to fit this DAG file on your card and mine with it. There is a lot of cards dropped already from mining ethereum.

But biggest drop probably will be when DAG file reaches 4bg size, because most of the mining farms where using 4gb RX 570/580/470/480  for mining Ethereum.  Because they have been the best price per hash and best watt per hash. If we check hiveos software statistics we can verify this https://hiveos.farm/statistics/ :

23% RX 570 4gb
14% RX 470 4gb
12% RX 580 4gb
2% RX 480 4gb

Roughly 50% from all AMD cards using hiveos is 4gb cards, and AMD has been the best performing Graphic cards for Ethereum mining.


So there is few things what you can try to expand you mining life with 4gb cards. They already are starting to make issue. Using software like Ethos and claymore miner, incorrect drivers etc...

So the things to do :

1. Ensure you're running HiveOS on the latest stable version and updates.
2. Switch your miner to the latest version of TeamRedMiner, Ethminer or Phoenixminer.
3. If your CPU has built-in graphics (iGPU), you can try enabling Internal Graphics on your motherboard's BIOS and ensure it's set to Default (Only applies if you have a monitor connected).
4. If you're still running into issues after trying the above, try removing the "REF" parameter in the overclocking panel.




Using phoenix miner you will get the cards working till at-least epoch 372-373 which is end of October.  You can achieve this also on windows but you might run into issues if you run incorrect drivers, best drivers to use is 18.12.1.1 to 19.7.5

Ethereum classic DAG file will reach Epoc 372 slightly faster around mid September , So i think Ethereum classic is in trouble of getting 51% attack around that time.

What will you do with you 4gb GPUs when you cannot mine ETH anymore?

REcent GAS price on ETH is insane which drives crazy mining profit.

Bios mod with current tools dont work, bricks the cards RX 5600XT

Here checkout i was doing some research on real ethereum mining profitability Calculators vs actual https://www.youtube.com/watch?v=XFDijlLYr48

I have had tested both Sapphire pulse and MSI mech , and hash-rates for MSI mech much better then Sapphire pulse unfortunetly ;(
Sapphire cards always has better built quality
