@Genoil What exactly does --farm-recheck do? Does it increase your hash or just update the console quicker? I've got --farm-recheck 200, and my 125MH/s hash is all over the place from 98 MH/s to 138 MH/s. Any help would be greatly appreciated!
@SIRacer09 it is the time in milliseconds between RPC calls to the pool server or (g)eth node that supplies the miner with new work. So a lower value is better, until the pool server decides to block your IP for DDoSing, so stick to what they recommend to use.
As a side-effect, that same interval of -in this case 200ms- is used by ethminer to calculate and display current hashrate. That's why it seems to have an effect. It would be much better if that bit ran in a different thread.
Perhaps someone can help me? thank you in advance I'd been reading up on all the gpu comparisons and decided to get a couple of MSI 390x's for a 2 gpu rig. I was anticipating around 30mh/s per card, but im barely scraping past that with the 2 of them. the hashrate of 1 card is only 18mh/s.
I'm running Windows 10 (can change to 8.1), 2x MSI 390x, ASUS M5A97r2.0 mobo, 4GB 1600mhz DDR3, AMD 3+ CPU (6 core) and I'm running this off a gold 80 1000W PSU.
@bob : You need to be more specific so that others can help you efficiently Here are a few suppositions : - Your AMD drivers might slow down your mining rate (you should use 15.12). - Make sure before running the miner you use the command setx GPU_MAX_ALLOC 100 and the other usual settings (you can find them easily in this forum). - add to your ethminer command line --cl-global-work 16834 --cl-local-work 256
Hey all I'am just curious does this card even has crossfire http://www.newegg.com/Product/Product.aspx?Item=N82E16814127913&cm_re=r9_380_4gb-_-14-127-913-_-Product I ask because I got 2 and I don't see any thing about crossfire I played gta 5 and some other games they just use GPU 0 nothing on the other one. I don't see crossfire in the catalyst manager I tried the newest driver 1st and I didn't see anything now I'am on 15.11.1 mining and its the same. so I just wanna know if it even has crossfire if yes just let me know how to enable it if you can. I watched videos and I don't see the option in the AMD catalyst where they have there's...
one more question do I have to have a motherboard that supports crossfire because I don't think this intel board "H61H2-MV" they are on does its a small board I had and I didnt want 3 cards on one pc with the fx8350. It makes one psu gets very hot would have to buy a psu for the fx8350. I got a 970a-g46 with 270x and fx8350.
I know its not needed for mining but as I said I'am just curious if it actually has the crossfire I see other with playing games and getting better FPS. if itd the board then I will just test it on the other board one day and see how it plays just wanna try it atleast once
I currently switched to AMD 16.1 they seems to run just as smooth as the older 15.12, but in my case it runs (dont know if just me, my net or other) stable (on etherminer.org). 2x280X 1x7970 1x380X aprox 80-82 mhs (avg 24 h).

Can't find any decent pics of the topside (power plug side across the whole top) of the card,but I don't see a Xfire "plug" on the pics I found.Can you take a pic of the side where the power plugs are???
My new Sapphire 380 4gig does not have Xfire plugs,so yours may not either

They are normal PSUs taking just under or above 300watts. I did not get it from the wall I calculated it from GPUZ. I cut the green and gray wires putting the together. The cards are undervolted to 70% using msi afterburner iam seeing 69A and 66W in GPUZ. The coreclock is 1050, memory 1500 and fan 80% with 67 degrees.

interesting! so people run 5x of the same card for simplicity? i have an r9 280x and i could add say, a couple r7 370s or r9 390s (whatever i can get a good deal on), to the same board? and just use separate ethminer instances?
@Rich2016 Yeah the newer AMD cards do crossfire through the PCIe slots, no CF bridges or ports required, and if i remember correctly this includes cross-architecture CF, IE: 380 + 290 but don't quote me on that
i was under the impression that you didnt need to crossfire them (or want to), that you could use them individiaully in the command line, especially in linux.
Are we still possible to mine with GPUs with memory < 4GB with additional settings like below? I'm currently mining with R9 290 with 4GB memory, and considering of adding some R9 280x video cards with 3GB memory.

I have x1 SAPPHIRE NITRO Radeon R9 380X 4G D5
What settings should i set to increase hash rate? And Where can i check the actual hash rate of my GPU?
Pool shows actual hash rate much later after settings have been made.
Need more precise method of determining hash rate.
This is what i have tried to do with overclock.
