There was also a cpu-load "bug" just a few CCminer editions back. The bug used a lot of CPU power, but also increased the hash rate. It is only with the most recent releases that CCminer can achieve the same or better hash rates. I'd like to see a command line switch that would allow the miner to engage the CPU for greater hash rates. On my dedicated rigs I'd engage the CPU, and benefit from the greater hash rate. On my work computer, I'd leave it out so that my desktop would not freeze. There was a similar switch in CudaMiner, and it was sometimes effective in mining script. If the CPU "bug" was ironed out and taught to behave well, I am sure that miners would use it when appropriate. --scryptr
I guess you are referring to the "bug" I introduced when initially submitted the improved neoscrypt kernel. I removed this: cudaSetDeviceFlags(cudaDeviceScheduleBlockingSync); Which looked to induce a little speed gain, without noticing it also produced 100% cpu load. We could add a commandline option to disable it, but personally I think the hassle and additional power usage doesn't justify less-than-one-percent hashrate gain. Still if it's optional, I see no reason not to include it (provided that what it does is well explained). BTW ethereum cudaminer has a similar option. And 50Watt more power on the rig.. So 50 watt for 1KHASH gain DETAILS, DETAILS-- I do not know the exact details, I was considering 10.2Mh/s vs. 10.6Mh/s for Quark. I am not the dev, just the miner. If the CPU can be tasked to improve a few of the algos, I am in favor of the command line switch. Quark hash rates are a "big deal" to any miner just now. Neoscrypt rates matter also, but, like Lyra2v2, you might need to mine the coin instead of a BTC exchange rate. VTC markets are looking up, I haven't traded FTC and the merge-mined companion coins for a while, but I just might. --scryptr

I have the feeling that the faster hashrate reporting, and maybe other issues, are not related to the reporting itself. It is now exiting lighting fast when I hit ctrl-C, it never was that fast, it always took some seconds. Now a blink of an eye. It looks like the jobs sent to the gpu are computed much faster (but the hashrate is the same), maybe they are smaller.... I don't know how to check this.

Hi All Being watching this thread with interest the past could of weeks & decided to move over from ageing old AMD's to Nvidia and build my first 750ti rig. which is now up and running I've got to ask tsiv how are you getting 5700 from the 750ti? mine are only doing 4600 wDragon Wrote a faster version of the lyra kernel. Magic. ah getting now 5.9MH/s (and up to 6MH/s with some stronger OC) on the 750ti... funny though that kernel doesn't perform that well on the 980 ( getting only 10.6MH getting about same as the public (kernel setting was way off) and my other private kernel is doing 15MH/s)

No the most profitable is Etherum.
but, if the 750ti was hashing lyra2v2 at 7,636 MHASH it will be more profitable than the public quark kernals. But it isn't. Even with the private kernals.

Ethereum?! Mining with 750 is ok only under Linux, Windows has too many bugs - like getting 5MH instead of 8-9 for unknown reason, or even getting 300-400KH under 8.1 Of 3 750Ti cards I have, 2 can mine with ~ 5MH under Win7, the third - 300KH/s under 8.1

I might have a look at that quark at some point anyhow mining vtc to just dump it right away on the exchange isn't really the point anyone having done that clearly missed sunday events

Quark seems to do 30KHASH bether per card. and the cpu load is 80%. +30watt(or depends on your cpu) The new switch is called -C (--cpu-mining) It should work on all algos, but not tested. I will test some more and submitt to github.
