I have  improved groestl-coin.

New hashrates

@sp

Reject rate on lyra2 is still high on release 50. I am only about 81% accepted. I have no special settings in the bat and using Windows 7 64bit.

[sp_]

I am getting this error and the non-responding program window then ccminer stops.
this is strange because i havnt had any issues with release 48
changing i or g did not help

This is a disconnect from the pool. Happens when there is a lot of traffic. You need to use a bat file  wait and loop.

or use a minercontrol software like "miner control"

does cuda 7 work well - compiling and stability and all? ...

I just tried one test compile of ccminer-1.5.48 and there were no issues. I don't have either centos7 or cuda7
running on bare metal yet so I couldn't test the compiled executable.

With the delays in releasing cuda on fedora 21 and the short fedora life cycle it only leaves a small usable
window to build a supported fedora based miner.

true - hence the reason for the question ...

we will have two spare machines at the end of the week when the farm rebuild is finished ( existing rebuild - not the new build ) ...

ill setup one centos and one sl machine to test with cuda 7 ...

if all works and is stable - the ccminer-spmod v50 compile will take place after that ...

if that builds ok - testing phase will go for a few days after that ...

i may pull one of the workers down ( 6 x 750ti oc lp ) and plugin a new hdd to it and test that way first ...

there are only 4 more machines to be rebuilt to f20x64 currently to get back to mining again - until the full farm rebuild to custom frames ... that should finish tomorrow - so the rest of the week to get all the other jobs sorted ( including the setup and testing of the multi-algo donation links ) ...

then the centos / scientific linux build will take place ... and the compile and testing of ccminer-spmod v50 ...

i can let you know of the progress ( or regress ) of the builds if you like ...

Yes,,,yes,,,yes! THIS is what I've been trying to get an answer to for these last several days. How do I get a workaround for this? More to the point...I need an example of the .bat file to set it up.

Thank you

edit; if ya go back about 9 post pages, I asked about this. I guess because I haven't gotten very involved, until lately, nobody thought to look at my posting much. I can't write code but I do know when something ain't right. Question...just what does the workio thread do? Is it software (code) related, hardware (vid card), or internet speed (not sure of tech term) related? If I knew what that did, I could experiment. Don't remember who, but somebody posted a example of the .bat loop file but I could not get it to work. Just running a simple one now but playing with the switches. My current file (I change and fiddle with it tho);

ccminer -a quark -o stratum+tcp://yaamp.com:4033 -u LV4oV0xyLWu6pntuq97L0PheeavJsALJYo -p mHung   -i 20.1 -r -R=3 --cpu-priority 3  

It's actually not running too bad. Still get the random workio thread disconnect tho. Sooo...how do I force a restart of ccminer. The vid card & driver doesn't seem to crash but things slow down, then...crap, nothing, workio disconnect. If I'm sitting here (which is a lot of the time) I just close and restart ccminer. I'd really like a set it, forget it, have a nice day kinda thing tho. I could make a beer run and it would still be mining or go to the beach (which is where I'm headed in a bit). Ya know. OK...done editing!  Well almost...I really would like a solution. I've forgotten more than I remember, so I leave things up to the ppl in the know...you guys. You're a great group, mostly, and I know eventually the info comes out.  Thank You very much for any replies. Bye, for a few hours...heading out for some fun in the sun.

Is you miner able to handle different cards? Or is it safer to run separate instances? One for the 970s and one for the 750s?

Did I miss the answer to that question or did it go unnoticed?
Do you need to run two ccminers when you have a mix of GPUs (750Ti & 970 for example)?

I believe that would be a YES. Different setting for different cards. Could be wrong, but it's what I would do. Oh wait, sorry, I know that you can run one instance of your miner, by using the command switches (-d). Look at your readme file. It's in there. Personally, I would run different instances of the miner tho, so if one card craps out, you can close the miner to fix that card while the rest keep going. Otherwise you shut them all down to work on just one. It's all a preference thing. Hope that helps. Done.

Hi Folks,

I'm seeing this:
 
"cuda error in func 'x11_sind512_cpu_init' at line 641 : invalid texture reference."


Can anybody help me fix this?

[go6ooo1212]

Just tested nist5 on my mixed rig ( 970 +750ti) with release50.

Without using i or g parameters reaches 27.8MH/s for 970 and 9.78MH/s for 750ti.
I tried these kind of combinations then:
-g 2 -i 19 --cpu-priority 3
-g 2 -i 19.5 --cpu-priority 3
-g 2 -i 20 --cpu-priority 3
-g 4 -i 19.5 --cpu-priority 3
-g 5 -i 19.5 --cpu-priority 3

The result is almost same: first 400-500 shares the speed is much more fast , but then slowly falls below the quoted speeds...

[rednoW]

nist5 is kinda slow (((

nist5 is kinda slow (((

Hmm I think its not at all , compared to AMD - Nvidia rules the hash...

I hope this question isn't off topic, I'm not aware of a cuda HW thread.

Does anyone have any experience with Gigabyte's half length 970? I'm concerned heat
would be an issue with everything crammed into half the space. If not it could be
suitable in a smaller case.

I run a Zotac 970. It is "half-length" as you describe it.

Heat comes mostly from the GPU core, (yes, VRAM and VRM's etc do generate some heat, but not like the GPU core does) so while I do not have experience with any of the longer length cards, I can say that my card works just fine. OC's decently well with stock BIOS.

is it in a case? ... or an open rig? ...

#crysx

It's in a well-ventilated case http://us.coolermaster.com/product/Detail/case/mid-tower/haf-912.html, but I sometimes just leave the side cover off. When the side cover is on, there is a 120mm fan right above the video cards.

@ bensam1231     In your bat file... if westhash goes down then nicehash takes over... but if nicehash then goes down does it go back to westhash?  thx

ccminer.exe -q -a quark -o stratum+tcp://stratum.westhash.com:3345 -u  -p x -o stratum+tcp://stratum.nicehash.com:3345 -u  -p x

Sticking my nose in, but you could try:

Code:

: loop

ccminer.exe -q -a quark -o stratum+tcp://stratum.westhash.com:3345 -u  -p x -o stratum+tcp://stratum.nicehash.com:3345 -u  -p x

TIMEOUT /T 10

goto loop

Thank you Doug...but the problem with that is in the goto loop. At that point it can't find ccminer.exe

@ DougB62...I'm still waiting for the fail to see if your file works. I may not be so smart...just an ass. My fingers were too quick to restart my miner. I do know tho that with your file I had to put my primary pool as the second in the command line. I'm gonna delete my comment below until I know if the kudos need to be applied.

Back in a few!

edit; tbear is right...dang it. I was really hoping dougb62 was correct. Thanks for the try; appreciate it!

No problem, and I'm busily searching for a working solution - may need something more than a simple bat file though

Your gpu is too old. My mod is for compute 5.0 or newer.
