The "-C" flag stands for the long form "cpu-mining" command that would be in a JSON format configuration file.
That's what the arg is called but not what it does. I had assumed it did what it said but it just uses more CPUto be more responsive to the GPU which helps the GPU hash faster. The CPU doesn't hash at all.
Why should the 2 cores in the cpu hash at all?? Bether to let the cpu aid the GPU's to reach the maximum output. -C is intelligent CPU hashing. Your miner is just HASHING

Just make sure you have one cpu core (including hyper-threading) per card or it can slow you down. I have an i3 with 6 750 ti cards and it slows down the hash.
So curiously, where are people getting 1MH+ on Neoscrypt and 25MH/s on Ethereum on a 1070?
I've been hunting around and Amph's quoted rates are no where to be found.

-C improves the hashrate but use alot of cpu.
Could someone plz tell me what - C does... I looked in the readme file and its not there. Thx.
CPU MINING--
The "-C" command line flag enables the "CPU Mining" boost in sp_ 's branch of ccminer. It makes a big difference in hash rate for some algos, as the cpu is assisting the gpu in processing the data. I remember chatting at you about it before. As far as I know, sp_ 's branch is the only one that uses this fllag.
It increased my Quark hash rate about 500kh/s to 11.5MH/s with my GTX 960. --scryptr
That's with an unoptimized CPU miner. If you want to co-mine with the CPU you could try cpuminer-opt.
It does quark at 1.2 MH/s on a i7-6700K. But I prefer to mine more CPU friendly algos.
I CO-MINE WITH CPUMINER-OPT--
I run 6 threads. BUT, the "-C" flag allows the cpu to assuust/boost the performance of the gpu hash rate. If you want a better explanation, you will have to ask sp_ . In simple English, ccminer gets a better hash rate with the "-C" flag set at launch. Results depend on the algo and hardware. I use the flag in all of my launch lines. And, I am usually runnning CPUminer-Opt at the same time, with only a small reduction in hash rate for both miners. --scryptr
We were both wrong, I looked at the code.
-C actually has nothing to do with CPU mining, it only changes how the CPU and GPU are synchronized.
It is not implemented in other forks as it is selected automatically when appropriate.
JSON LAUNCH.CONF FILE--
The "-C" flag stands for the long form "cpu-mining" command that would be in a JSON format configuration file. An example for ZPOOL follows:
{
"url" : "stratum+tcp://mine.zpool.ca:4533",
"user" : "COIN ADDRESS",
"pass" : "rig1,c=COIN",
"algo" : "lyra2v2",
"intensity" : "21.3",
"cpu-priority" : "5",
"cpu-mining" : "true"
}
This is called by a launch line like "ccminer.exe -c zpool.conf". I was unclear as to what I meant by "cpu-mining", and with your focus on coding CPUminer-OPT, you possibly misunderstood.
The only fork of ccminer with this switch is sp_ 's, and it works. It forces co-operation between the cpu and gpu that yields better hash rates. Your code inspection is informative. Apparently, auto-selection is not always working to yeild the best results. --scryptr

The final conclusion after what I and crysx have been through is either one core per high density card or more on board memory ..like 32 gigs.
Nvidia is fine.

EDIT: Is it regedit you make the change to 30?
Yes, it's done to the registry with regedit.
Here's a link for the .reg file if you don't want to edit the registry yourself:

I just remembered ..I forgot to turn off onboard graphics too.
EDIT:I have had that .dll for a long time I don't know if I added it to that computer. I may have so to make sure I'm going to use regedit and set to 30.
EDIT: Got it....lets see if thats works.
I could add that as 32 or 64 bit..doing 64. I wonder if there would be any relationship to the amount of hashrate to sp build or 64 build or 86 build?
EDIT: Nope..... looks like one cpu core per high density card. That has to be the problem.
After it crashes on reboot I get this....
Then on 2nd reboot it installs. I even tried disabling hd on board graphics.
Sorry sp for messing up your thread.

Try to disable Intel graphic card to bios , and uninstall driver intel from windows with DDU .
What do you mean plz? Thx
