I submitted another 100KHASH in quark.

the 970 is passing 16,6 MHASH now on standard clocks.

Thank you for your pullrequest. My gigabyte 970 went from 520-540 to 560-570KHASH. The 750ti's seems to be up 5KHASH, but I think will tune the kernals when I get time.

Hi sp_, i am testing your new 1558 version, here are my QUARK results:
rig: AM1M motherboard with APU 5350 (25W TDP) 3x gigabyte GTX 970 G1 stock speeds, 14.04 LTS (flash drive), cuda 6.5.19 drv 346.59

default intensity is best BY FAR!, so you NAILED IT

I tested intensities from 20 to 24, all gives me at least 500Kh less, per card, than default.
at intensity 20 is when weird things starts to happen, power consumption SKYROCKETED!, from 650W to 780W   WTF!
at intensity 20 and 21 memory usage reported by nvidia-smi is about 200Mib which is very odd!, at default intensity (not specifiying it) i get 1433 Mib usage per card, at intensities of 23 and 24 memory usage drops again but to 650Mib per card.
at 23 and 24 speed reduces from 16400 per card to around 14000.
another weird thing is that, if i specify -i 22 i get about 500kh less per card than if i don't specify anything, and the memory usage also drops from 1433 to 650Mib.

also at default intensity i get the usual spiky power consumption behavior always had with the GTX 970 about one tick every 800ms, but at lower intensities the power consumption is more constant. (I have a bar graph (vu meter like) power meter i made to track things like this i can do a video of different intensities and power consumption behavior if you like).

Rig: AM1M motherboard with APU 5350 (25 TDP) 3x Gigabyte 750Ti stock speed 14.04LTS (flash drive), cuda 6.5.19 drv 346.59

I found no difference with previous release 1557 in performance and power usage.
if you need me to test something, let me know, happy to help.

The popup error comes from werfault.exe (windows error reporting) so having an independent bat loop killing it every few seconds solves that issue:

:start
title werfault killer
cls
timeout -t 3
taskkill -t -f /im werfault.exe
goto start

Hi

it seems that -g 2 Parameter is not working anymore
with release 1.5.58 on GTX 750TI -x11

not necessary anymore?

Rlz 58:
~ +100kh on quark for a 750ti ( 6750kh/s )
~ +15kh on neoscrypt for a 750ti ( 195kh/s )

release 58 gained up to 500KH/s more on the rig of six 750ti in quark...

It seems it is working now:


Thanks very much .

Unfortunately it doesn't show the speed of processing...

Here is my contribution to the ccminer-sp effort.

I just posted a pull request:


Please note that it's not just an hashrate increase, there is a lot of code enhancement and cleanups under the hood.
Also note that I didn't test it on cards other than 970.

Donation BTC address is in my signature.
(Depending on how my effort is supported, I'll see whether to post my future works or not)

Enjoy! :-)

Try to add -l 5x24


ccminer -a scrypt -l 5x24 ....

in the command line

Hi, I'm having problems running it with scrypt:



How can I bypass this problem?
Thanks

EDIT:
I tried the latest cudaminer version from github and it seems to work with it:

yeah. I corrected the release notes.

quark is faster on the 750ti as well.  (from release 57 to 58 on One of my test rigs the gain is 70khash per card.)

X11 needs to be finetuned.

The current default intensity for the gtx750ti is
-i 5 and for  compute 5.2  -i 22

Please help me find the best intensity settings people

uh sorry!
"neoscrypt +10KHASH gtx 970"
so it's on 970, not 750ti ;-)

I had one commit rigth after the release 57 (10khash on the 750ti) as well.
(10khash on the gtx 970)

Thanks SP_!
Last commit on neoscrypt is from 15 days ago (just before the previous release), are you sure you committed it all?

- neoscrypt +10khash on the 970 (1.8%)
- qubit +50khash (compute 5.2)
- faster x11, quark (compute 5.2) (quark +300khash on the gtx 980) (1.7 %)
- yesscrypt has been removed.(faster to mine with cpu)


1.5.58(sp-MOD) is available here: (09-08-2015)

https://github.com/sp-hash/ccminer/releases/

The sourcecode is available here:

https://github.com/sp-hash/ccminer

I submitted another speedup in quark and x11. Looks like most gain on compute 5.2 cards

Note that I removed a big memory buffer in the x11 hash(simd) intensity can now be set to 28 or more. (but default on the 750ti is only 5)

If I ctrl-C the mining window on Windows I get the error popup. But my bat file uses the start command to open a seperate window
for the miner. The bat file keeps running and when it decides to switch pools it issues a taskkill which closes the existing miner
window and a new one is opened. There are no popups but I have no idea if there are any ugly messages that appear in the
window as it vanishes.

If your GPU sometimes goes into a degraded state following a ctrl-C  (assuming signals on Windows is as on Linux)
there seems to be no difference between SIGINT and SIGTERM.

nvidia-smi -r --id=0 doesn't work on the primary gpu so I still have to reboot.

WINDOWS KILL--

The problem I had when I was attempting to use the YAAMP protocol for auto switching was that an error message from Windows would pop up and interrupt the batch file.  Although I disabled Error Reporting, Windows would still send the alert and interrupt the batch file.  Manual interaction was required, mining stopped.

Currently, I do everything manually.  I left-click the red X at the top right of the window, and close ccminer.  If I use ctrl-c, there is a chance of the degradation problem.         --scryptr

can't get the new vert miner to on 750 need help bat,yes got the new miner ,test port
