Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

my r9 380x really getting annoying 1067/1500 still gives 96-97 h/s anyone knows how to increase or is this highest right now?

Why is devfee finding so much more shares so much faster?
Because of a different pool? I'm mining on suprnova

When you switch pools, difficulty starts off low and then ramps up.
Switch to mining at flypool and you'll probably get considerably better returns.

why is flypool so much better

They have ~50% of the total ZEC network hashing power. If you want consistent payouts, flypool is the place to be.

damn thats a lot of devfee https://gyazo.com/61befa67e8f981f90fbe9b421cff24d9

check the time spent mining rather than the shares. should be roughly 90 seconds

When you connect to a pool, the stratum server has a default lower share difficulty, then adjusts based on how fast you return them.  Lower difficulty shares are faster, but worth less on pool.  Pool adjust difficulty to prevent overloading server with a crazy amount of small shares.  In the end, it doesn't really matter what kind of shares you mine, your payout is the same.  Small shares will have less stale due to faster speed, but more network overhead.  Pools will probably increase default share diff since there are faster miners now.

When devfee mining, a ton of shares show up, because it is a new connection, so it is mining the easy shares.  The same behavior when you first start the miner, you will see a ton of shares, look for messages about server share adjustment.  For my 6x 470s, share diff starts at 272H, then goes to like 6500H after a minute.

Is this card a decent investment?

to bad i can't that in the US at that price best i can do right now  for a 470 8gb is 199 on amazons US site . i can get a  power color 480 4 gb on new eggs us site  for 189 $ . it's hard to decide the 470 for 199 with 8gb or the 480 for 189 with 4 gb both have free shipping to me . MY bad sorry just noticed thought your add said  8gb . i can get 470's for less with 4gb in the US .


To answer you question  yup  there worth the money, i have three RX 470 4gb .

I would love to be able to buy one for cheap in the US but the postage costs to the UK would probably push the price over what I would pay here

I also could not get more than 100 h \ s on r9 380 4g, twisted configuration, but 96 - 98 h \ s maximum.

Returned to eth / dcr, I get 1.6 $ \ day, and until more Zcash 1.27 $ \ day does not produce.

Shameless plug here, but I just got my MSI Armor 470 4g and I put it to work.  Lets just say its pretty awesome for the price.  I put the review up at www.cryptominingtalk.com (there are no ads or monetization on the site).  Posting this cause some peeps were interested in it.  Its a good buy.

I'm testing it now. Was on miningpoolhub before.

stop mining zcash it's a virus

[ghostfaceuk]

stop mining zcash it's a virus

In that case with the way the price is dropping we will all be cured of it soon enough

Guys, he's a doktor. It must be true!

i have searched for the past few hours for how to mod the 380 memory straps. can anyone help with this? I have searched hex editor and have only found 200,400,800,1375,1500,1750 groups. Thanks!

can someone take a look at the stock bios and tell me what I am missing to strap the memory timings? I have tried searching for the timing groups. first one is XFX R9 380 2Gb and 2nd is MSI R9 380 4Gb

6xR9 380 periodically resets GPU0 speed, and the miner errors appear non-existent cards, with which it can be connected?

GPU 4 crashed, since its 0 H/S. Look at your speeds.

[adaseb]

For everybody with 380, you can try these bios's which were optimized for ETH.

I don't have a 380 so no idea if it will do anything.

Claymore miner uses two thread for each GPU. So when it shows GPU 8 or 9 is crashed, you divide that by two, that is GPU 4. It is confirmed by the 0 hash rate of GPU 4 in the picture.

Good Job Man!!!!!

How are you keeping your temps that low, my 390x sits at 93c

93 is too high I'm using -tstop on 80
try cleaning them from dust maybe it'll help
also considering that V5 was way cooler than v4 and v6 is same as v5, I can't imagine what temps will you get on mining ETH

here are mines

still cold until now

I can confirm that bug. Plus i got an issue when all 4 GPU working with 100 % Load according Trixx info but one is 0 hash\s.

Pool sets new share target: 0x000f612a (diff: 4261H)
ZEC: 11/16/16-22:49:05 - New job from zec.suprnova.cc:2142
ZEC - Total Speed: 374.150 H/s, Total Shares: 204, Rejected: 0, Time: 00:30
ZEC: GPU0 102.007 H/s, GPU1 134.362 H/s, GPU2 0.000 H/s, GPU3 137.781 H/s
ZEC: 11/16/16-22:49:13 - SHARE FOUND - (GPU 0)
ZEC: Share accepted (63 ms)!

It happens after some time of mining

It's a bug, will be fixed in next update. Divide card number by 2.
