Since theres serious shortage of more powerful cards, maybe it would be good diea to check what
are these cards able to do. I guess cryptonight algo is main contender here. Sadly, I don't have any,
so someone else will have to come up with numbers :)

I picked one up just to play with it.

MSI Aero ITX Radeon RX550 4GB OC edition  (there is NO 6-pin power connector on the card - just FYI)

I have not tried anything with the bios yet.

Here are some screenshots of what its doing:

Win 10 Pro 64bit
Claymore's Dual Ethereum v10.6  (Ethereum only)

You can expect the same performance like 1050Ti. 12mhs upto 15mhs if your lucky. power draw is also 75watts same with 1050ti.

investment wise, its cheap and faster roi but required more other PC peripherals to power a 12 - 13 Rx550.

If you can wait for 2-3 weeks more the manufacturers and suppliers will start shipping the bulk GPU fresh from the factory.

Hers some numbers, modded.

Msi rx 550 2gb LP   - 450 H/s

XMR-STAK (1203MHZ/1985MHZ 1500+ STRAPS) (2XTHREAD(16) PER GPU, INTENSITY 320)     

I guess its the ultimate cryptonight card...aside of not been practical (you need 4 them to reach Vega
performance, or two to erach RX580), its even cheaper (here you can buy 5 RX550s for one RX580)

for cryptonight is better 640 streams or 512 sp version ? (with bios mod)

My two RX550 runs stabel @ 13,8-14,2 MH/s on ETH. Cryptonight also about 440-460 H/s. Bios is modded.

Can you share your mod please?

Use this here and make one click Timings and Flash your Card then:

What is your model/memory brand of theses cards ? I found gigabyte and xfx brands here but I don't know what will be better to do this mod.

I get the same results with my 18 ASUS RX 550 4GB cards, but I got all my card for less than $100.

what brand and memory of you cards?

Here is a screenshot of 9 - RX 550 4GB (Asus Hynix) mining IPBC. Keep in mind the new algo hash rates are 2x...

Gigabyte rx550 2gb  14.1Mhs  on pirl and  475 on xmr

I have 9 msi aero itx 4gb rx550's.  ive used the one click bios modded method and cant get these cards to mine stable unless they are stock with zero changes in afterburner.  I could use some help with this if anybody is willing to help out.  id even be willing to send some mined coin once I get them figured out for your trouble!!  

These numbers seems really high for me, the cryptonight ones atleast. i would guess it gives around 350 - 400 H/s on cryptonightv7. Its highly effective but a god damn mess to connect if you got many cards, as it has no 6 pin connector.

I have over 50x 550s.

12 x each rig.

Each does around 480h/s for 42w

What motherboard and brand of gpus?

Serious shortage of more powerful cards? The shit has hit the fan and local markets have started flooding with 2nd hand mining rigs and individual mining GPUs.

I don't see how you can't find a good deal on used cards. It just take a little time and effort.

Discussion initiated on 1st of february... that's why.


Anybody have a "Baffin" RX 550 and mind to share core,undervolt and memory for CN heavy ?

I have same 1xFan cards with Hynix memory... But only 11.5 Mhs on ETH & 500 on CryptoNight using same modded bios. What memory do you have on your cards? What I need do to increase ETH hs? Mb I set wrong-low OC? Anyone help?
Thanks!

hashrate for CN is solid for the price, but you need a ton of them to make any dent

I think there is no CN V7 / heavy miner for those Cards anymore. But for the Price they had a nice hashrate.

I have the same problem. Someone can help, pls?
Thanks

May i ask, what bios do you use, could you share a link or name?

Sure!

I have this exact issue. MSI Aero ITX 4gb. Can't get them stable unless completely stock and one thread on XMR stak. I've tried afterburner and OverdriveNtool for overclocking. Sucks being stuck at 250h/s.

Has anyone got the MSI Aero ITX 4gb with hynix to get even close to 400h/s stable?

My sapphire pulse Rx550 2gb easily get 460 h/s on Cryptonight.
Mod bios using PBE 1.6.7 with One click timing patch

Depending on the type of memory, if samsung or elpida can be up to 14mhs but if other stack at 12mhs max. For how to oc it, please follow at this forum there, or please at the anorak or techpowerup, there you will be given tutorial and info related to it.

Yeah, I have a pile of these cards, too.  I've got them around 360 on CN-v7....trying to push towards 400.  If I can even get close, I'll share my bios.  Every other 550 I have, especially the 2GB cards are 425-460 all day long.....

Also, can you send me your stock bios?  I'm looking for the Hynix H5GC8H24MJR for comparison.

Did it! 13.8 MHs from each cards using Claymore on Hive OS!
Core Clock (Mhz): 1200
Core State (Index): 3
Core Voltage (mV): 875
Memory Clock (Mhz): 1994 1932 1936 1936 1926

Just an FYI... Best Buy has XFX 550s 4 Gb on sale for $69.99!

Has anyone tried these on X16R/S ?

I can try. Give me pool & wallet config. I am on HiveOS. Can try sgminer.

Cool, I think hiveOS also supports Avermore which should get you 25% more.

https://pool.virtopia.ca/connect.html

That is one of the better pools to mine on they're not huge but payouts are decent and as soon as the blocks confirm.
You can grab a wallet here:

If Avermore isn't native to hiveOS you can import the miner form here:

https://github.com/brian112358/avermore-miner/releases/tag/v1.4.1


Please do share some results.

Today we are going to focus on the cards just below the mining sweet spot and that would be the NVIDIA GeForce GTX 1050 Ti and the AMD Radeon RX560/550 series cards.  These cards are the models right below the NVIDIA GeForce GTX 1060 and AMD Radeon RX 570, which are highly coveted by miners.

Sorry for delay!
Nothing... Have HW error in SGminer. Mb U can some help me? I have already try change int, gpu threads, worksize & use with stock OC.

How did you do it? Are you dual threading or single?

Yesterday did some BIOS fixing on someone elses RX550s (first time worked on RX550s, btw)
12.9-13.5MH/s which surprised me because they have below official spec memory chips
onboard (1500MHz micron)

RX550 2GB 1250/2000  Hynix.
V7 = 500+
Heavy = 330+ (1350/2000 = 360+)
ETHash (Callisto) = 14.5

RX550 2GB ethereum Mining Hash Rate?

DAG too large already for 2GB

so cant mine eth? 4gb version?
