This is quark right?

try  -i 22.9 (the default for 750ti)

Do you have more than one card in the rig? Is the card trottling? Check the temperature, if it reaches 70 degress c it will automaticly downclock,. Also make sure your card is in the p0 state. Defalt is p2


Performance modes
P8 = idle clock speeds and lowest power consumption
P2 = the default mode used when your PC boots or no drivers are installed.
P0 = Gaming/Load. This mode only accepts boost/offset values


Did you build it yourself? Use cuda 6.5 and not cuda 7.0 or 7.5

-i 22.9 seems to help gotten it back close, I had already tried -i 23 before posting. I'll try tweaking it a little more.
Card hardly ever gets over mid 50c so heat or throttling is not a problem. Yes have cuda 6.5 in use. W7 64bit per your .exe file.
Almost all my rigs are open air bench setups, so heat is not much of a problem with anything with the AC running

For this release 59, I'm using -X intensity parameter instead of -i.  My older setting of "-i 23" seems not working well for me.
So, I dropped -i and used -X instead (setting the cuda threads count).

Here's what I found:

Release 58 and before:
-i 23 == 8388608 cuda threads
-i 24 == 16777216 cuda threads (default value if you don't specify any intensity)

Release 59:
-X 128 = 8388608 cuda threads
-X 256 = 16777216 cuda threads

Basically, number of cuda threads = 256 * 256 * (value of X)
sp mentioned it few posts above.  Please correct me if I misinterpreted anything

Here's a heads up about performance states. nividia-settings powermizer has it backwards.

All discussions I have seen refer to 0 as the highest performance level and this is confirmed
with nvidia-smi.

But nvidia-settings powermizer has them reversed with level zero as the lowest and
level 4 as the highest performance level.

All of my previous posts were using the powermizer values so I apologize for any confusion.
I will be more clear in the future.

57 with -i 22.9 will test 59 with -X 128/256 now.



59 -X 128 below -X 256 was at 9970 max. no SS at 256 saw no need.

Wich driver are you using?

Can you try release 58?

For GTX960, probably you'll want to try with "-X 64" or somewhere between 64 to 128.
For my GTX970/980, I'm using -X 128.  I limit the TDP of the card, so lower CUDA threads count scores better.

Driver 353.30, sorry no more time to test today got to get some sleep.
Quick note with 57 & command line -i 22.9 -l 16x24 its showing me hash in this range.

@ Law I tried -x 64 and 96 in test, no help with 59 for my setup.

So a friendly update cause I'm sure you guys don't watch your power meters. Release 59 for Neo increases power usage by 30w per 970. I went from 190w to 220w.

That's a 15% increase in power usage. I only saw about a 5% increase in hashrate for Neo as well. I have since reverted to .56 as the new version reduces efficiency quite a bit.

In API it doesn't give me the correct fan percent/rpm (localhost:4068/hwinfo)...

GPU=0;BUS=1;CARD=GeForce GTX 850M;SM=500;MEM=2147483648;TEMP=66.0;FAN=0;RPM=0;FREQ=901500;MEMFREQ=900000;PST=P0;VID=10de;PID=1391;NVML=-1;NVAPI=0;SN=;BIOS=82.07.47.00.05|OS=windows;NVDRIVER=353.62;CPUS=8;CPUTEMP=0;CPUFREQ=0|�

Also, I noticed NVML=-1, is it normal?

[sp_]

I have compiled it with the api disabled as default:

in ccminer.cpp:


int opt_api_listen = 0; /* 0 to disable */

I'm running with parameters:
--api-bind=127.0.0.1:4068 -b 0.0.0.0:4068

Is it normal to give 0 to fan percent/rpm, but giving correct temperature?

There's a problem with neoscrypt in r59.

It uses 100% of a cpu core for each thread, Linux and Windows.

I've found the (regression) bug, will post the fix asap.
This will also reduce power consumption ;-)

already fixed it..

You beat me to it... Sorry for the trouble.
