Having a terrible time getting this to work with many of the pools, at least if I try to do more than one algorithm. Maybe someone can help me out? Here's my conf file for a system with 2x7950 GPUs:

I started the the sample conf file from Nicehash, and that didn't work well at all -- nonce errors, hw errors, sgminer exiting after 60 seconds, etc. Then I read through this thread and saw stuff about setting rawintensity instead of xintensity or intensity, so I tried that. I also tried using "algorithm" instead of "pool-algorithm" as another suggested. I also tried the 3xxx ports at Nicehash, and that didn't seem to work right either. Basically, none of the changes work. The current status is this:

If I start with the above config, I'll end up with a "ckolivasTahitiglg2tc22400nf10w256l4.bin" file. WTF? It's using the wrong kernel, ignoring pool-thread-concurrency, and it runs at intensity = 8 (the default if you don't set anything). Pretty much all of the pool-specific settings are completely ignored! If I add a generic intensity, algorithm, and thread-concurrency, that gets used instead, but of course that only works with one algorithm so it's of no use. Help?

Edit: Oh, and sgminer quits after 60 seconds right now. That seems to be my "scan-time" value, as changing that from 15 to 60 at least helped a bit. But scan-time isn't supposed to cause an exit from mining. Ugh....

Edit again: Nope, it's not "scan-time", but I still get 60 seconds before sgminer quits every single time I run it. Here's the error from the latest run I just tried:

24 hours uptime, 1 SICK -> DEAD card on a R9 290X, same setting as before.

Whoever it was, mrbdo or whatever ---> WHAT IS YOUR PARTICULAR REASON for not wanting to extend the SICK timer?

Mine to extend it is to TEST STABILITY OVER A COURSE OF A FEW DAYS OF UPTIME

I'm having trouble tweaking it for my 290x, would you mind sharing your settings? 

[lucid_ity]

After extensive testing with this sgminer and reading through all of these posts, it appears it does NOT switch algorithms on the fly (at least with my config).  I'm sort of skeptical about those who are saying they have algorithm switching working with no problems.   Could you post your entire config for us?

I've tried using "pool-algorithm" and "algorithm" within each pool.  This seems to have no effect in actually switching the algorithm when the pool is selected.  This is obvious from all of the errors received right after switching.

"algorithm" in the main portion of the config makes sgminer use this algorithm for ALL pools.    If algorithm is not specified, ckolivas is used.

[platinum4]

Okay, I have some results in,

Switching from kernels "marucoin-mod" or "darkcoin-mod" over to scrypt kernel "alexkarnew" WILL SHUT OFF ALL OF YOUR GPUs (not SICK, not DEAD, OFF status)

Anybody have insight into this?

Is the ADL GPU idle patch in here or not.

This config works switching from X11 to X13 to Keccak, but it BROKE when I tried 'alexkarnew' kernel for Scrypt.

This config above is with a kernel I am trying "alexkarold" your results may fuck your shit up too.

Above config has specs for 3x R9 290X

Here is my windows build with latest changes: https://www.dropbox.com/s/28e1tv9ho64eolc/sgminer_v5_0_05062014.zip
There is no ADL GPU idle patch, we tested it and driver drops clocks and gpu load automatically, if all pools dead/internet connection disabled. Let us know, if in your case gpu runs at full speed with all pools dead/internet connection disabled.

That gives me 2.8M on X13, we're far from 3.4M-ish.  What are you getting with those settings?

[mannyg]

I keep having sgminer quit on me after 60 seconds.  Sometimes it accepts a share with 0.00 diff.  Just spent 4 hours testing and trying different settings and the 60 second quit kept happening. 

[MysteryX]

Tried for over an hour to get something decent going between the x11 and x13 pools but nothing seems to be working correctly. I'll just leave everything on x13 for now.

If somebody has a conf file that works correctly with 7970's i'd love to take a peek.

[TheMathGuy]

I finally managed to get it fully working on xubuntu 13.10 (multi with ALL algorithms). It took me about 7 hours of painful troubleshooting, but hey, it works.

Issue

thread was not cancelled in 60 seconds after restart_mining_threads

Cause
sgminer.c
line 6224 - bool soft_restart = !work->pool->gpu_threads; - wtf??
line 6290 - quit(1, "thread was not cancelled in 60 seconds after restart_mining_threads"); - right...

Workaround
remove all "pool-gpu-threads" from the config and use global "gpu-threads".
this ofc sucks, but will do till the bug-fix.

p.s.
I do miss ckolivas ; (

[jimlite]

Nice goal and project, but don't release it before it WORKS.

I haven't even tried it yet after reading all these threads,
but from my experience, you will NOT get cards to not be
sick, work at all, be dead, or hash at previous speeds once
you go in and out of Scrypt-N. Scrypt-N switching needs
a reboot if you switch algos.

Elun this build crashes out immediately with HW errors even if you use the exact same .conf file from the previous build.

Something we're missing?

I get 3.4 steady, check and make sure you have an MSI AB, gpu-threads2 etc

Post back with your results please.

My question is, how did it accept the 1 share at the Scrypt?

It's obvious this thing fucks up really bad when it tries to flip to it.

Here goes another.

Something wrong on the Nicehash side or what?

Anybody know what THIS IS, and how to get rid of it?

It's pretty clear we can get this flip-flop between X11/X13/[maybe] Keccak - but when flip to Scrypt----> NOPE!

[dhsc19]

This is working ok for me except for keccak. When mining keccak, I'm getting a lot of stale shares and job not found.  Roughly 20% reject rate for keccak.  Still submits accepted shares, but tons of stale and not found.  The rest (scrypt, scrypt-n, x11, and x13) are working great.  No problems with Nicehash algo-switching for the last 24 hours using it.  Running on Ubuntu 12.04, compiled myself from source.  I'm using an ASUS 280x.

Average hashrates:
scrypt - 771kh/s
scrypt-n - 355kh/s
x11 - 2.650Mh/s
x13 - 2.750Mh/s
keccak - 355Mh/s w/ ~20% reject rate
