Can anyone recommend me the best driver/sgminer versions to use with my 5970s?

I'm currently on sgminer 4.1 and 14.4 drivers. I've heard that the 14.6 drivers / newer sgminer versions don't affect older cards?

Yes. It is faster. With this miner speed is same as X13 algo and even more bit faster.

Looked in the source; no bitblock.cl

Sorry for my mistake. Mix up with djm34 topic. Also I have seen than all changes by aznoboy84 have been merged to official sgminer v5.0 beta.

Ok, follow-up to my above message. It appears that the issue is related to the on-board intel video card in the systems I am mining with. I had to completely remove the device in the control panel for SGminer 5.0 to recognize my AMD cards. I even tried -d options to make it so sgminer didn't look for it, but that didn't work either. Once I disabled it, SGminer 5 worked fine. Why wouldn't SGminer 5 look beyond the intel video card, as other version did?

Edit: The work-around is to add: --gpu-platform 1 to the start of my config line in order for it to ignore the Intel card. No idea what changed and why this is now needed when it never was previously, but I'm thrilled it is working thanks to Tex81 on Github!

A bit perplexed... I'm a long time miner, with 50 machines, mostly Windows 7 64-bit, and all have 14.6 RC drivers loaded, and are mining fine with a version of SGminer 4.1. I'm using the nicehash compiled versions, and have not compiled myself yet.

I went to upgrade to SG5, and I cannot get it to launch at all on all the different rigs I attempted the upgrade on (5+).

The error:

I have a bad feeling that I'm missing something very obvious, such as needing to copy files into the SGminer 5 directory from the AMD driver, but I couldn't find anything on that and haven't had to do that for other versions. Any ideas would be greatly appreciated!

I have proposal for stratum extension to support algorithm change without reconnects.

First, we need to normalize name of the algorithms; example:

Code:

scrypt, nscrypt, x11, x13, x15

Miner subscribes to server that it is capable of switching algorithms. It also sends parameter list. Each parameter consists of 3 parameters: algorithm name, factor and cost. Factor is speed in MH/s (it is only important to be relative to other provided factors of other algorithms), cost is daily cost of rig in USD.

Example for 2 algorithms:

Code:

{"id": X, "method": "mining.algorithm.subscribe", "params": [["scrypt", "1", "2.5"], ["x11", "4.2", "2"]]}\n

Server then calculates which is best algorithm for this rig considering provided factors and costs. Before any work is provided and on algorithm switch, server sends (example to switch to x11):

{"id": null, "method": "mining.set_algorithm", "params": ["x11"]}\n

Immediately after that server sends new difficulty and new work.

How about this extension is NOT messed up like extranonce subscription the first time around? Having a miner "subscribe" to calls that a server may or may not support makes little sense. The pool should inform the miner during connect that it supports this extension, and then allow the miner to respond with multiple algorithms if desired. Otherwise, when the miner sends your proposed "subscribe" command to a non-supporting pool, it is going to break pool connectivity (just like extranonce subscribe caused all kinds of problems for users).

This one is not problematic at all, because it would be turned on per pool - "multi-algorithm" : true and additional parameters to define supported algorithms, factors and costs.
Without this flag, miner does not subscribe to algorithm changes.

Sounds like you failed to put the ad files in ADL_SDK folder before compiling

Okay, went back and recompiled. Looking over the command history I saw where I messed up. Put a file path to the AMDAPP when I should have done ADL_SDK. I double checked everything this time and I'm getting all the stats I'm expecting. Thank you for the suggestion but for some reason it hated my config so I went with a nightly build as kenshirothefit told me about.

Now that I have that up and running I can get X11 going as expected but Scrypt gives me hardware errors faster than you can keep track of. I'm using the same config that gave me successful and stable 1mh/s between my two 270s.

Any ideas?

edit: seems I can't get a stable scrypt has anymore no matter what version I use.

HW seem to be kernel agnostic (have tried both clov and zuik.) The nightly build produces massive HW while the standard download produces approximately 1/card per 10-20 seconds.

Code:

{"id": X, "method": "mining.algorithm.subscribe", "params": [["scrypt", "1", "2.5"], ["x11", "4.2", "2"]]}\n

Server then calculates which is best algorithm for this rig considering provided factors and costs. Before any work is provided and on algorithm switch, server sends (example to switch to x11):

{"id": null, "method": "mining.set_algorithm", "params": ["x11"]}\n

Immediately after that server sends new difficulty and new work.

How about this extension is NOT messed up like extranonce subscription the first time around? Having a miner "subscribe" to calls that a server may or may not support makes little sense. The pool should inform the miner during connect that it supports this extension, and then allow the miner to respond with multiple algorithms if desired. Otherwise, when the miner sends your proposed "subscribe" command to a non-supporting pool, it is going to break pool connectivity (just like extranonce subscribe caused all kinds of problems for users).

I have proposal for stratum extension to support algorithm change without reconnects.

First, we need to normalize name of the algorithms; example:

Code:

scrypt, nscrypt, x11, x13, x15

Miner subscribes to server that it is capable of switching algorithms. It also sends parameter list. Each parameter consists of 3 parameters: algorithm name, factor and cost. Factor is speed in MH/s (it is only important to be relative to other provided factors of other algorithms), cost is daily cost of rig in USD.

Example for 2 algorithms:

Code:

{"id": X, "method": "mining.algorithm.subscribe", "params": [["scrypt", "1", "2.5"], ["x11", "4.2", "2"]]}\n

Server then calculates which is best algorithm for this rig considering provided factors and costs. Before any work is provided and on algorithm switch, server sends (example to switch to x11):

{"id": null, "method": "mining.set_algorithm", "params": ["x11"]}\n

Immediately after that server sends new difficulty and new work.

There is no need to have the server do this. It would be just as easy to create a client-side switcher that can figure out when it should switch between different algorithms. I've created a switcher like this for the TradeMyBit pool that uses sgminer v5 no-restart switching (and the old method of switching for backwards compatibility). As long as the NiceHash pool has an API that returns the profitability of each algorithm then it's just a matter of deciding if or when you want to switch.

See https://bitcointalksearch.org/topic/ann-trademybit-algorithm-switchermonitor-661827

why couldn't this determine the profitability on its own, just give it your hash rates and cost and get the price info from the web then have it switch as necessary on ANY pool

The point is that it could as long as NiceHash (or whatever multi-algo pool you want to mine at) expose the appropriate API required to get the profitability information for the algorithms they are currently mining.

Of course as it is it wouldn't work but it would only take a small number of tweaks to get it working with other pools. If that is possible (i.e. the required API exists) and people want it then I could look into it.

i know it isn't setup that way now but that would be something i would like to see built into cgwatcher...
edit: well it looks like cgwatcher can do this as long as you pay for the coinwarz api key so you can see the profitability of more than just sha256 and scrypt coins
then again i dont want to go to the trouble of selling those coins myself so i will just stick with a service that does it for me

Can anyone show the configuration file for this release?

its not a release.... its a proposal to make a change in stratum code and miner code

are you saying that the x15 kernel from that miner is faster the the one from this one?
i get 3.5 mh/s on 290x with 1000/1250 clock

Yes. It is faster. With this miner speed is same as X13 algo and even more bit faster.

you can go here and open a new issue to try to get the devs to look at it

To developers:
Can you add X15 core from this miner: https://bitcointalksearch.org/topic/ann-sgminer-with-x11x13nist5quarkanime-kernels-compatible-146-amd-drivers-658438

X15 speed:
7950 (1080/1400) - 2.8 Mhash/s
280x (1060/1500) - 3.2 Mhash/s
270 (1100/1500) - 1.8 Mhash/s
