Hello i reach 14,7 mh with my RX550 Sapphire Lexa Pro and Micron memory. i will upload a screen later.
in my opinion, every RX550 will reach 14 mh with the right timings.

Hey man I have this exact same card, actually 6 of them, and I'm having loads of problems increasing my hash rate, would you be able to share you bios ? I would love to try it out, currently mi mining turtle coin on the chuckwa2 algo

I looked at the discussion of the miner on this video card, and found an interesting point.
On almost every page, users ask for an original BIOS for a video card

Before flashing the BIOS, save the original BIOS of the video card in order to restore it if it turns into a brick ..

Man, this discussione is from 2018. You cann't mine eth with that kind of 4GB card at reasonable speed in 2021..

Go to whattomine and see by yourself what's best for you

You will see that you can mine 5.5 $day in total of erg with 6 of that card.
ERG is mined with autolikos2 algos.
SRBMiner and TRM are the two best miner out there
You will be able to reach around 25 MHs per card.
In order to do so, is better to increase the frequency of the Lexa core.
YOu will find more info in the threads of the miners

Trtl is another option, as you can see by yourself. 10 MHS / card is about right with that algo and that card

He can mine ETC+ZIL also, on ERG it goes to 30mh per card.

Use polaris editor and strap your cards

Mine are RX550 2GB cards with baffin core and elpida memory.

986mhz core and 1901mhz mem should give you around 14mh. I even downvolt them to 800mv in OverclocknTool. Running cool at 62-66 celcius

ive got 13,9MH/s with clocks 1150MHz and 2000MHz, but after some automatic restart at night -> clocks were reset to default values. so I OC it again to 1150 and 2000MHz, but now i cannot get 13,9MH/s. Ive got only 12,3MH/s with these clocks. wtf? Do you know what's happened? Now if i set clocks to 1124 and 2000, i can get 13,5MH/s. Whats happened, do you have some idea? Huh

Before -> 1200MHz and 2000MHz => 14,2MH/s
after something -> 1200MHz and 2000MHz => 12,3MH/s .... so i changed clocks to 1150MHz and 2000MHz
now after restart -> 1200 and 2000 => 12,3MH/s , with 1150 and 2000 => 12,3MH/s ..... so only with 1124 and 2000 => 13,7MH/s Huh

i dont know whats wrong with it.

Hey. Which card manufacturer? Give your OE bios.

That depend the type gpu's memory, eg. micon,elpida,samsung etc. I thing samsung that's can get 13-14mhs, the other just stack at 12mhs max.
You can use PolarisBiosEditor to mod your bios, just click "ONE CLICK MINING PATCH" . For change the timing strap section i can not suggest it, because too harmful for the GPU.

I have 18 Asus RX 550 4GB cards. They are all Hynix memory. 14 get 14.1 -14.4 MH/s, the other 4 get between 12.5 and 13.8 MH/s.

GPU: 1200 MHz / 900 mV
Mem: 2000 MHz / 900 mV

Bios modded!

I have this card also, with lexa/hynix memory. Maybe you can share your mod bios to me. Plz contact me if the bios not free of charge. Thx.

If you put the old bios back, something else has to be different.... you might have just learned your lesson...

guys can you help me? Do you have some idea, why my hashrate cant get 14mh/s anymore? After yours first help, I got 14.2MH/s with gpu 1200MHz and memory 2000MHz. But gpu had high temperature, so I tried to install latest AMD driver using DDU and flash new bios to my card. But after that, I can get from my cards only 13.6MH/s with gpu 1124MHz and memory 2000MHz.

if i OC gpu to 1200, hashrate falls down to 12.5MH/s. so i have no idea whats wrong with it. i tried to flash back my bios, install Blockchain driver, set claymore parameter -ethi 1 to 16. But still same problem.

Do you have some tips how to solve?

I don't recommend buying 550 cards at today's prices. I got all of mine for $85-$100 USD. You are better off getting RX 570/580 4/8 GB on amazon for $280 - $320.

can you tell me how to bios modded ? and share aplications please ?

Learning how to BIOS modding is something you can find out for yourself by simply searching Google. I would strongly advise that you follow online guides very carefully because you could end up "bricking" your GPU if you screw up the timing or BIOS itself.
