Mining with 1x Sapphire r9 380x + 1x MSI r9 370

[spiete]

Using ethminer-0.9.41-genoil-1.0.7

Mining without overclocking.

Here are the settings

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
C:\Mine\ethminer107\ethminer.exe --farm-recheck 1200 -G -F http://127.0.0.1:8080/dw1 --cl-local-work 256 --cl-global-work 20384 --mining-threads 2


Getting float result from 30.2 to 34.5 to 38.9.



What can i do to make it more stable?

And what can i do to gain more H/s?

Is --farm-recheck 1200 good timing or i need to reduce it and why?

You need to reduce the farm-recheck to 200. It means your miner check if there is new work every 200 ms.

here is what i get when i set 200

It is better to use the Claymore Ethereum miners. It gives you consistent display of hashing speed and stable.

It's 2019 now. How much hashrate is R9 380 or R9 370x doing in mining ETH or other Ethash coins? Best to mine these cards with Windows 10 or Linux OS?

I have these old cards kept in storage. Maybe it can be still useful to mine Ethash or CN coins?

The R9 370X is basically the R9 270X rebrand which is a rebrand of the Radeon 7850. So its an old old GPU and it featured max 2GB of ram. So you definately can't mine ETH with it since the DAG is well over 3GB. Your best bet is XMR but the profitability will be very low.

Same with the R9 380, if you got the 2GB you can't mine ETH but if you got the 4GB version then you should be able too. Don't recall the speed, I think they got like 20MH/s or so but used more power than a regular RX 470.

If you got cheap power then go for it.

LOL you can use google? 370x 2GB?   it has 4GB

The 380 go up to 25mh with some optimizations.

this cards will make you lose money. Almost 100% sure unless you live in a third world country where you can get kW at 0,06$. In that case you may get enough a month to drink a coffee.

This is insane. People are desperately poor, OMG.

The exit of money from one card 0.4-0.5 dollar. 15 bucks a month. Enough for a can of good coffee.)

Wow honestly I never knew that. I swore that Pitcairn type of GPUs either use 1GB or 2GB of ram. Because I had a few of the R7 370X and they had fast Samsung memory but it was 2GB. Never knew 4GB was an option.

The 370X was a good card, the older 7850 were bad because many of them had 1GB of memory and the memory was bad Elpida type of memory and wasn't good for overclocking. But I remember when I used to mine XMR with my 370X, due to the fast GDDR they were almost as fast as the R9 280X GPUs, maybe 15% slower or so.

They had a good run but these days with most games or mining algos they aren't just worth keeping.
