The normal ETA for a new Claymore version is "when I think it's ready".

Easiest way to find is check Claymore latest posts......

You can go to any users page and see their latest post....

That would be a terrible idea. You will have to wait until Claymore releases a Linux version or dual boot Windows.

Hi Claymore. Thanks for the good miner. This is not just a good miner, it's the best miner!  But I have a problem with it.

1.   The rig with three cards RX 480. Almost always, when you start miner, one of the card showing low hash rate. Usually it is approximately two times lower. Typical for my config 170-175. One of the cards can show the 40, 80, 110. Each time a different. In order to get the highest hash rate I have repeatedly restart miner. Often this can be done repeatedly restarting the computer. When the card shows the maximum hash rate - CPU loading is 10-15%. At the same time, the GPU loading, on card that show low hashrate is 100%.

2. The second problem. After working about 15-20 hours miner hangs. Writes: Open CL device hung and miner can not be self restarted. I restart the miner repeatedly to get high hashrate.

3. If I put fourth card in rig - Radeon HD 7970, the miner worked for some time simply halts the system. This restart is possible only  disconnect the power supply.
 
What I've done:
1. Install the system Windows 10 from scratch. I put different drivers. Recommended drivers 15.12 - do not see my cards RX 480. Now I use drivers 16.11.4
2. Changed Reiser to other - it does not solve the problem.
3. Place the cards in other slots - not solve problem.
4. Removed from the system Radeon HD 7970, install the system from scratch. Radeon HD 7970 is now living in the other rig.

My config:
 The motherboard MSI Krait Gaming 3X socket 1151
Intel Pentium Dual-Core G4500
8GB of memory
Swap 32Gb
Radeon SSD
3 X Sapphire RX480 nitro

Launch miner's this line from *.bat file:
ZecMiner64.exe -mport 0 -i 4 -zpool eu1-zcash.flypool.org:3333 -zwal <my address> -zpsw x

Miner Version 7.0

I hope for your help, and help the community. Sorry for the English. It is not my native language.

I use remote manager with no issues.. how's your setup?

Claymore wouldn't need an API; the switching would be done locally and you access the APIs from the pools. A local controller app would launch the miner(s) and connect to them via the 'mport' to tell it what pool to use. If all the miners had a benchmark feature as well, it could determine the speed for each algo to base the profit calculations off. This is all that Nicehash do but they lock it to only their pool's API.

No zec miner for linux and nvidia cards as far as I know

I think it mostly depends on environment, dust and temperature. In my case in 4 month period I burned down only one ref RX480 out of 270, fans working great, a bit dusty inside but cleaning them regularly expands the lifetime

How long have you had your 480's?

They have warranty for 3 years so it doesn't matter.

Your 280x should of been making almost $1/day before ZEC, maybe your electricity is too high
