Each HVC miner can vote for how many blocks will be rewarded when a block is found, they get this vote when finding an actual block I believe. Currently HVC rewards 577 per block. If you look in most HVC pools they will tell you what the expected next change in block reward is. I think the HVC ANN house an overview of how it works.

Thx for the explanation.
I suppose a higher reward also brings a high difficult, right?

It could lead to a higher difficulty, but also to a lower value to BTC because you're "printing" more money for the same capitalisation.

wooo hooo. i need to check in here more often! currently getting 118000-124000 on Heavycoin pool with my 750 ti's hope these coins are worth it biggrin.gif

I left the single GTX 750 in my system mining overnight, and woke up to my seeing that the card's fan was at full throttle and with no output to the montior. I'm not sure what happened to my system that caused this, could have been a rare case of one of the hard drive connectors coming loose. I turned off the system and turned it back on a few minutes later, all working again.

I just got back home so I can tell you now. I don't use Afterburner but the power use of my cards average about 85%.

I have mined more than 70 HVC in the last 24h with this new ccminer.
At this rate I can achieve around 500 coins a week.

Awesome.

For some reason ccminer keeps crashing on my two 750tis. I have set the clocks back to stock now to see if that makes a difference... any ideas?

Splitting the cards up into pairs (3 instances) results in about 16M per instance, which is better but not good. I suspect that the CPU is choking the performance. The poor G1820 is running close to 100%. Or maybe it's the memory bandwidth, because I'm only using one stick. I'm gonna see if dual channel makes a difference next time I have physical access to the rig. Just remote controlling it at the moment.

Unlike cudaminer, I don't see a flag to enable/disable cpu processing in ccminer.
Try to contact the ccminer dev and ask for a ccminer update which uses less cpu.

Since you have 6 cards and a dual core cpu, try this:

in windows task manager --> Processes --> (right click) cccminer.exe --> Set Affinity

3 cards on CPU 0. Other 3 cards on CPU 1.
May increase hash rate a little.
I think your cpu is a bottleneck. Get a better cpu or move some cards to a different machine.

Mine worked fine all day (yesterday). When I went to sleep it crashed 15 minutes later... damn.
One hole night without mining.

Yeah, same here, even at stock.

We need a bat to restart mining after x period of time and another one to close the ccminer instances after x seconds to create a loop.

Guys, do you know if the Maximus Hero can run 6 gpus?

You could just use the Windows Task Scheduler to do this.

Create a 'CloseMiner.bat' file

add 'taskkill /IM xxxminer.exe /F' to it, where xxxminer.exe is what the process exe of your miner is.

Do a timed task in Windows Task Scheduler that runs 'CloseMiner.bat' every however many hours, and 30 seconds later runs your normal mining .bat file.

Lather, loop, repeat smile.gif
