Hi R0land, I bought one of this to test 11268-03-20G (Sapphire Pulse Radeon RX550 2GB)
Unfortunately it came with Elpida memory: max hash 290-300 on CryptoNight with sgminer 5.5.5-gm stock bios
Do you know if it worth to mod bios with Elpida mem?
I don't know how to have RX 550 cards with Micron mem. It seems they are random...

With this card you can reach 410 h/s @18W(GPU-Z).
With the 4GB Micron Version 450 h/s @23W(GPU-Z).

It seems like rx560 is quite good in performing cryptonote algorithm compared to other gpu with same pricing range.

I think the RX 550 is also quite good in performing XMR ... more than 400 h/s with less power consumption compared to the RX 560.

Are you sure you can get more that 400h/s on 550? It seems it's also difficult for 560 to hit 400h/s. For a 550 it looks like a miracle.

It works since 4 weeks without problems at my home. Grin

The RX550 is the perfect gpu for mining xmr, because cryptonight charges the memory and 8 gpu cores are enough for the rest. The bottleneck is the memory.

What brand is your rx 550?

Saphire Pulse Radeon RX550 4GB Micron Memory

Thank you guys, I decided to give it a shot... and it seems that with the "lifting" to the timings and a boost to the mem freq the results are much better than the stock bios even for Elpida model.
I'm getting about 390h/s @1875MHz but I'm testing the stability since already @1900 I'm getting BSODs in a bunch of seconds.
Don't you know if it is recommended to increase the mem voltage to try to work @2000MHz? Because at stock voltage (1000mV) I think it will be hard for this card to go beyond 1875MHz.
I would also consider to decrease a bit the GPU frequency and voltage not to stress the card but I don't know if it will worth.
