Thanks, I am also interested on Var-Diff vs different static diff relative to hashing power, it's seems it can increase/decrease income regardless the miner used, really interesting tests you are doing as a service for the forum- GJ.
P.S - in the first test I was very curious why pool was choosing almost double the diff for coolMIner, even though I was thinking it was too high- it came out to be better choice by the pool stratum?

P.S - I advice you to choose the lowest intensity that doesn't reduce the hash-rate (+- 50kh\s acceptable), as you have seen the speed penalty is lower then on ccminer, and maybe this way less rejects of job not found/discarded work because new bock, it should be around 18~19. and other rig you can try 20~22 what you like.

JackIT: what do you think,  next round on same intensity 20~19 but without static diff? it looks like the Var-diff gave better results(or 10 diff was too low?).

Hi Guys, i'm getting an error on my mining rig when using coolminer, its "The application was unable to start correctly (0xc000007b) ... "

Its a windows 10x64 machine 8 gb ram , core i5 7400 , with 9 gpus , 6 x 1080ti, 3 x 1070ti.

Things i've tried, installing cuda 9.2 , installing latest nvidia drivers 398.11, checked vb.net version is 4.7 , ran as administrator , checked its not blocked in firewall .  Tried 1.1, 1.2 , 1.3 version and no luck.

Any ideas ? works great on my desktop and love to get this working on my rig.

I'll send a Gincoin to anyone that can sort this out for me as a thankyou .

Thanks for the info, but I am concerned on the miner side, if the GPU is working to find high diff for too long while new blocks are coming in 20~40 seconds then every time it breaks out of hashing loop and gets new job, so you should choose more optimized diff value that doesn't take the GPU too much time to find a share between blocks otherwise you are wasting your GPU time.
This is relevant for every miner not just mine.

P.S- I think you are already loosing coins for running ccminer 2.2.5  .

NP, thing is that I was playing with the code for months so I remember how it works  .
Thank you very much for your time, its real fun to watch the competition  .

Edit: it's interesting, on first run my miner@16 intensity  had clear lead on ccminer @ 22 intensity but now it's like ccminer works better at 16 intensity, (unless we have troll here who tries to send shared to same address lol).

Moreover- this pool stratum is't very smart and wastes your hashing power, coolMiner is stuck @ diff 18 while ccminer @ 12, this is very bad since I see blocks comes to pool every 30~60 sec and that means that card are stuck in loop for finding too high diff share and every new block it breaks out from loop and you got no share.
The lesson from this is not to trust the pool and set the Diff according the hashing power and block per min so you can send shares in time between blocks.
Edit: now it set diff = 26 on coolMiner(faster rigs get higher stratum diff ), there is no chance 4 1080Ti will send enoght shares in between new blocks(few seconds).

Edit: if you can- next run  try testing it on 21 intensity like many miners used on 1080Ti till now, and set static diff on the miners so there will be no Diff changing factor.

It should be 16 on ccminer too, where did you get 22 as default?

Thanks :-), But why you are testing @ Intensity =16 on my miner?

Update: coolMiner-v1.3 !
Applied the suggested fix by JackIT to "Fix slow start in multi gpu-rigs".

any test for 1.10？

I'd suggest you stop acting like a hypocrite, it goes a long way for credibility.

Also where does that come into play in this thread when you just talk about 'rounds'? A round on a pool is the work on a certain block. I'm sorry for not reading your mind and your ambiguous terminology that you make up on the spot that's already used for other technical definitions. Or do you talk about hours in such a way to convey a certain amount of self-import regarding you turning a miner on?

Maybe you should figure out what you're talking about before you actually talk about it?


Jesus I'm not even going to start tearing down your test results, right off the bat you think setting intensity on three different miners is the same thing? Different miners can run at different intensities and contribute the same amount of work or some with less intensity then another running with more depending on how they're coded. That's why the intensity tuning game is still very much a part of being an experienced miner... or for the sake of testing you run them at default, whatever that is, however doesn't represent a tuned rig. A good tester would find the optimal intensity for all miners they're testing.

Jackit, can you explain this part on your stratum difficulty test? Static stratum diff set to 40 (~Mh/s / 2), if you're running 12 1080ti, I would have thought your mh/s would be closer to ~228 mh/s? I'm trying to gauge my difficulty setting for my config on 8x 1080ti and was wondering, thanks.

All the yiimp based pools are cheating you.

If you run with a higher difficulty like -p d=40 instead of vardiff you gain 5% but the pool doesn't find more blocks. That's why you should solomine...
