Guys, is the situation still the same for you or has your hpm recovered?

I'm getting now 19 hpm with my 7970s. It looks like fixed. Thank you for your efforts. BTW difficulty rising too fast, it looks like we can't earn after 1 or 2 weeks later Also price looks down on Bter :/
Indeed.  I think this should probably show that the coin isn't GPU resistant enough, in the time we've had GPU mining the difficulty has increased by about 50%.  And that's just as a result of our pool, imagine if there was an open source miner.
There is no spike on the chart on the moment GPU mining was introduced: http://s4l1h.github.io/mmc/
If not for GPU, botnets would eagerly fill the void IMO.

The worst part is, botnets did not go anywhere with introducing GPU mining.

Yes, we are having growth pains on the moment indeed. They are temporary, problems should be gone in an hour.


i hope that you dont have any backdoor in this gpu stuff.. first you are taking many users in and then you just say "back in few hour" ... while you are mining to your own wallet? i am only hoping that i am not right
No, it is for real. Since almost blocks are found by pools now, you can check other pools and see that they are found there instead.

also it's been an hour not mining anything :-\
You mean, your shares don't get submitted, or is it something unrelated?

It appears that we have a substantial inflow of new miners and have to deal with overload in yet another system. This is going to take another hour or two.

Everything is back to normal now. Sorry for the inconvenience!

My hpms still same around 14 :/
Would you please try restarting your miner? Displayed values are very slow to change after you have ran your miner for a long time.

Guys,

We are experiencing overload in some of our subsystems, this is why your hpm has dropped. It is not related to increased difficulty.

Things will get back to normal in under an hour, stay tuned!

Yes, I am doing like that. I am running with 4 different miner instances like 0-1-2-3 with different .bat's. But still no change :/

Regarding activity, the algorithm prevents full utilization of cores: they have to spend significant time loading/storing values to VRAM which is terribly slow comparing to just calculations. Besides, load distribution is uneven over time, this is why you observe the sawtoothed load chart. Still, the hpm seems too low for 7970, any chance you could try Linux?

Is there any relation with increased difficulty and hpm ? Now difficulty is 0.00006042 is there any chance low hpm because of rising diff ?
No, pool's share difficulty has not changed. Besides, hpm/wpm does not depend on it.

@reorder,
trying to get the miner working on a fresh ubuntu 12.04 install.

Do you have any clue why it's states "out of ressources" ?

VLIW architectures (5xxx and 6xxx) seem to not work with the miner, I am still figuring this out.

I also have some problems with my 7970s. I can only get 55% activity with my 4 GPUs. I get 14 hpm and 13 wpm with each card. I should get 19-20 with these cards. Is there any way to run this program with full activity ? How can I fix this problem ? If I use CGMiner, I can get maximum performance but with this program I only get half of my performance. What should I do ? (I already tried registery fix)
Please try running 4 miner instances, one for each card.

Hi I have two Gigabyte AMD 7970 GPU and the issue I am having is that it will mine for a few hours and then activity for the GPU's on the AMD VISION Engine Control Center goes down to 0%. When it is mining activity is 99%. Then I look over at the command prompt to see if it shows any sort of error and it doesn't show any sort of error

It just shows what the last share was like the hpm and at what time.

Is anyone having this issue or have any idea what is going on? Also clock settings for GPUs are 975 and 1255 for memory.
I'd suspect card hanging due to overheat here.



It was off for 7 hours while I slept and the mining program was open it just wasn't mining. Shouldn't it start back up on its own after 7 hours of "cooling?"

I went in and manually closed the mining program and restarted it again. It just gets really annoying because I have to keep doing this every few hours.

Any recommendation as to what can be done to stop this? Thanks for your response!!
When (if) the card hangs, it does not tell miner something went wrong, so the miner can only sit there and wait for response. Perhaps you have to force your fans to always run at 90-100% speed.
