Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[zyzzyva]

1. I have used other proxy solution before this, and usually ethminer sends shares to Geth via a proxy server, and when block is solved it is accepted by Geth... since this version v4.2 is directly hashing into geth, the only indication that I successfully mined a solo block is on the CDM console or local MIST wallet, correct?

I think you would see an accepted share in Claymore's miner for each found block. That's been my experience so far with Expanse/gexp.

EDIT: I can also confirm that v4.2 works for Expanse solo mining.

completely useless bug report follows, but I feel obligated to offer it.

4.1, dual mining in linux.  after several days,

read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable
read(): Resource temporarily unavailable

attempts to restart mining just hang.
soft (AHCI) reboot fixes it (implies not a hard hang at GPU/driver).

Was fixed a few days ago, re-download v4.1 or use 4.2.

awesome--will do.  thanks!

How to make this16gb virtual memory?   And where?
Could it be reason for low  280/370/380 series  amd, hashrate?


Ok I found but what  consequences could  have to small size?

Claymore, is this fix relevant to your miner

https://github.com/Genoil/cpp-ethereum/issues/36

It could fix some low difficulty shares, at least in ethminer.

My miner does not use any sources from ethminer, so any bugs/fixes related to ethminer are not related to it.

Yes, I was just curious about the underlying idea, that sometimes 'a nonce matches with previous headerHash but is submitted with new headerHash resulting low difficulty share'  These shares could find blocks and uncles.

Looking forward to your next version with remote management   Thanks.

getting about 18-21 mh /s for eth and 480-520mh for dcr ethi 8 and dcri 50.
How can I get better performance? I don't have luck increasing them even with overclocking. The hashrate just don't change o.O. Can anyone help? I'm using 16.3 driver though. 8GB ram, 4 x 380x all at stock setting for the above rate.

For me the sweet spot is with ethi 16 and dcri 30. That's the combination that will produce a better ETH/DCR balance in my rigs

If you have small virtual memory and some of your GPU cannot be recognised by the miner and cannot mine.

Thank you for the release. But i can't understand why my own monitor utility connected direct to the wallet shows the hashrate only for original ethminer. My request code

Code:

"{"jsonrpc":"2.0","method":"eth_hashrate", "params":[],"id":71}";

Maybe you can look at this issue ?

Miner does not send hashrate in http mode. I thought it is useless. So you can see sum hashrates from all ethminers somehow? Explain how you do it and I will check it.

Are the R9 270's functional w/Claymore's DP miner? I've got a box of them and in the process of building a new rig.

A have a rig with 6 x 270x happily mining at 80~82 MHs

I send JSON-RPC request to my wallet described here https://ethereum.gitbooks.io/frontier-guide/content/rpc.html and then read response with javax.json.*

Code:

Returns the number of hashes per second that the node is mining with.

Parameters

none

Returns

QUANTITY - number of hashes per second.
Example

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_hashrate","params":[],"id":71}'

// Result
{
  "id":71,
  "jsonrpc": "2.0",
  "result": "0x38a"
}

I have some R9 270X as well...quite happy, if I had a box of them , I'd get mining before its too late.
Eth only, nothing fancy , no overclock and such.

2 - MSI R9 270X 4GB     14.17~14.2
1 MSI HD 7850 - 2 GB     11.08~11.12

pulling 53.2~53.4 MH nice cool running.

I got sum 270x to. First i test it with only eth. I get 14.8 mhs ( thats poor when i compare it with other miner, i get around 16) but when i switch to dual mining i get 15.5 for eth and 240 for dcr.

Its already too late for you. You'll never get ROI. Diff grows and grows 
Hashrate with 5 Cards is slow. What is your power consumption?
