Sapphire RX550 4GB - how to get 14MH/s?

[mikibeth]

Hi guys, i have searched on this website and found many guys, who was able to get hashrate about 14MH/s with RX550. Please help, how can i reach that? 

I did bios mod - 1500straps, shaders unlocked, OC => and it equals hashrate about 13MH/s, but not stable.

Could you give me some tips, what to do better?

Lexa or Baffin ? Mining what with which miner ?
Wrote down the setting here, and may be, someone will help

Depends on each card man, it's not a exact science
13mhs is very good on a 550

[fanatic26]

Just because someone has it working at 14mh does not mean that is the norm. Its all very specific to the parts used to construct your card, you should be happy with 13mh on that junker

Baffin. Mining with Claymore 10.6.. I tried Claymore 11.6. but i ve got only 12mh/s with that.

I set GPU clocks 1124MHz and 2000MHz for memory.

I saw photo with mining rig with 5x Rx550 with hashrate 72MH/s (14,5MH/s per card).

I know what baffin's can unlock gpu units.
You do that ? Maybe there is the secret.
Before i thik 550 can give 10-11mh only

[mikibeth]

yes, i unlocked compute units already. 10CU before, and after unlock 12 CU.

I think only samsung memory could give you 14mh/s because in rx 570 and rx 580 if your card is samsung memory you can get higher hashrate.
Try to use the GPU-z and check if what memory type of your card.
If your memory card is hynix you get low hashrate and micron memory could give you around 11 to 13 mh/s.

[mikibeth]

its micron memory. 

With 2 cards, rig was stable 13.3MH/s per card, but after i add third card its unstable about 11-13.2MH/s ,

and after some hours there is error: Watchdog: GPU hangs in OpenCL call, exit error.

and sometimes BSOD

You unlocked the cu with srbpolaris ?
Have you pimped your timing ?

Claymore starting with 11.4 does have a better kernel for  baffin

did everything ?

ok, now you launch claymore mining ethereum only and let it figure out the intensity 8/12 that's the range

Then: you run hw info and look for no error, if no error increase the memory.

Now you dual mine xvg!

Put the same -dcr with the same number Claymore suggest for "Ethereum only"

+- 1
and TA - DA!
you will get  around 14.5
unless I forgot something..
got 3 baffin with micron, don't worry you will get that

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!

to skablast:

Yes, i unlocked CU with SRBpolaris v3.4, then i apply 1500+ straps in srbpolaris, and flash bios.  I will play with claymore 11.4 or 11.6 and improve OC now, thanks.. wish me luck



to whoismoses:

its great, ill try your clocks, thanks

you know the power consumption? real power consumption

[mikibeth]

i set Claymore 11.7 with these parameters: -mode 1 -asm 2 -dcri 6 -etha 1 -ethi 12

then core 1200 and memory 2000. and yeeees ive got 14 - 14,2 MH/s. ..... but very high temperature, 68C and 98%fan.. should it be better? 

[whoismoses]

you know the power consumption? real power consumption

For a 9 card rig, the power meter at the wall reads 464 watts.

[skablast]

mmm, lower that core,by 1030/875 ?

dcri 6 isn't exactly the number I got written down, are you Dual mining or not ?

Could you tell me your Claymore parameters, please?

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.
