Topic: Sapphire RX 550 2Gb Best ROI ~ 450 H/s cryptonight (Read 1125 times)
Any idea how to update the confid for v8, im getting just over 250 for version 8 monero using xmrig.
Is this tuning for algo Cryptonight Legacy or Cryptonight V7?
cryptonight v7 memory elpida.

You didn't write for what type (manufacturer) of memory is this strap, so I suggest people don't try it
before we find out. Nothing too bad can happen, but less experienced people could have problems to recover
their cards to working condition
monero 7 2 threads 432/12
heavy 2 threads 224/8

Try it and some improvement is suggested.

Nice share tutorial oc with rx550 2gb. Anyway i want use more than that, so maybe next time i'll find rx 580 for my plan mining. I hope next day you can give me tutorial with rx 580. Sorry i am newbie at mining world. Thank you sir/mam 
For modding the bios for memory strap timings, what is recommended? I used to use custom memory strap timings for eth for 470s and 480s but never looked into memory strap timings for cryptonight
I just use the PBE one click mod, it does the job great, unable to squeeze more with custom timings.
I saw an old thread that claimed Gigabyte rx560 4gb can get more with custom timings, but the guy who wrote it wanted a ridiculous amount of money for it.
Since its cryptonight, it was probably Matthew, not me
, but "ridiculous amount" is too broad statement.If you have 1000+ of the same cards, your ROI for BIOS would be 1 day or less even with minimal increase in
hash rate, so don't take your own case as general rule

With undervolting you can get power consumption down below 35W with the 550/560.
I have my 560's undervolted to 910 mV and they only draw 32W each. Clocked at ~1200/2160. 535 H/s with xmr-stak and 505 H/s with Claymore. But I use Claymore despite the lower hashrate because it seems to be more efficient at finding shares.
A tip with these cards when mining Cryptonight: Most of the time the highest stable memory clock is not optimal. The proper way to judge the optimal memory clock is by how well the card finds shares. For instance if your max stable memory clock is 2100, you might want to try underclocking to 2090/2080/2070 and watch to see the point where the card starts finding the most shares.

550 looks cheaper than 560.. they both hash the same h/s with cryptonight and have the same power draw? any reason to get 560 over 550?
560 2gb is pretty cheap and superior to all 550's for mining Ethash coins with small DAG size. Most 560's will do ~15-16 MH/s and 550's only ~12-13 MH/s.
I have my 560 2gb cards mining EXP (expanse) it's very good because of low difficulty and stable coin price. I use MPH and auto-exchange it, but only when the price on the bigger coins dip.
What about cryptonight algo? I'm wondering the optimum hashrate vs power consumption of 550 vs 560
On Cryptonight power consumption is virtually the same, depends on how much core voltage it runs at, the 560's undervolt flawlessly.
550 is only better value at Cryptonight if you're lucky to get 480-500 H/s (hope for Elpida). Many cannot do over 450 H/s.
560 2gb is guaranteed 500 H/s (Hynix or Elpida doesn't matter) and the better value if you can find it cheap.
With undervolting you can get power consumption down below 35W with the 550/560.

It is better not to buy anything else. They take up a lot of space and give a funny profit. And the main thing is limited in the capabilities of mining on other algorithms. 2 GB graphics card has long exhausted its capabilities

I noticed that mining ETH to, a little less hashrate and you get more valid shares, i will lower all clocks of my rigs
.

How does rx 550 compare to 560 for ROI and hash per power consumption?
baffin / lexa ?
