Why would voting on the block payouts have anything to do with

I'd be pushing the fan speed up a bit to keep those temps down.. Also, you can push the core clock speeds up and pull the power target down a bit to lower the voltages and decrease some of that generated heat.

Still wish they would give more love to compute 3.0 cards, and tweak the performance for GK110 cores.

As I understand it the reason for the boos! is the implementation of VARDIFF which adjust difficulty. It takes a while for that to settle down to your miner.

1000 more hash/s in ccminer with GTX 750 Ti

Edit: My cpu was throttling. Recently updated motherboard bios and forget to turn off cpu throttling in the bios. After turning off Cool 'n Quiet (aka PowerNow, SpeedStep), my hash rate went from 12-12.5 Mhashs to 13-13.5 Mhash/s.

Make sure your cpu is working at max speed.

When cudaminer was running, my cpu was always working at max speed with -H 1
But ccminer uses cpu only a little and therefore my cpu was throttling down.

1.4GHz cpu --> 4.2 GHz cpu gives me 1000 more hash/s.

Thanks for the tip. not only did it lower my temp, also faster hash rate.

Already discussed...
It's normal because of vardiff. zhpool has fixdiff.

I think HVC diff has raised a lot and now I'm able to get "only" ~40 coins a day with one card. Previously was around 65~70.
post #857 of 1291
Yup, something like that per card...it's still good but not as good as it was.

Right now if you have 750s YAC is better by a slight margin, not worth it to switch for now though, specially since hvc price dropped a bit, if it rises it'll be better to stick to it.
post #858 of 1291
I'll stick with HVC for now.
Maybe will try the H2Ocoin launch today and then go back.
post #859 of 1291
Batch collection and task scheduler mojo complete...it seems to work and it even disables and enables devices in to recover from crashes without losing hash but it reverts the cards to stock clocks :/

As a sidenote: some guy ported the cudaminer scrypt kernel to sgminer and it works! biggrin.gif That means no more of this mumbo jumbo with a functional API. Problem is it's only for scrypt and Maxwell. mad.gif

Just installed my first three 750ti wink.gif getting 12Mh/s avg. on heavycoin.
Which miner do you use for adaptive-n?
