CCminer(SP-MOD) Modded GPU kernels.

[scryptr]

scryptr you are getting about 40-45% of expected performance from your 280x's. with even mild over clocking (1100/1500) they do 6.5mh/s per card using Wolf's recently released bin files.

Yeah, it's been a while since then, surprised more people don't know.

X11 HASH:  CUDA vs AMD--

To be fair, I re-downloaded and substituted the Wolf Tahiti-x11 binary.  This time I took the additional step of write-protecting the *.bin (binary) file before booting sgminer.  I got the following results upon firing up the same sgminer as in my earlier post:



I am running my GPUs at 1030/1500, stock clocks for my 280x cards.  I will try faster clocks later, but I am having a real problem with stability.  GPU0 crashes within 10 minutes if I don't disable it.  I disabled it at about 9min 30sec, after I clipped the image above.  It had started to misbehave again.

Any card management tips would be appreciated.       --scryptr

Change your intensity setting to xintensity 128. You'll see a very significant hash rate jump. Also, are you using sgminer 5?

I am running sgminer 4.2.2-, the build identifier is in the posted image.  It is a set of pre-compiled Linux binaries, released by the dev team just before Christmas, that reportedly had Wolf code.  I keep downloading and compiling sgminer 5.0.1-, but began having stability issues a few weeks ago.

Thanks for the tip, I'll try it.       --scryptr

The 22th public beta(windows executable) is available here: (28-12-2014)

http://www.filedropper.com/ccminer22

The sourcecode is available here:

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


Not many changes from release 21 but.

Faster quark(200khash) and x11 (20khash). (750ti)

And more CPU usage

Yep, seems to be an improvement Not much, but noticeable:


Thx a lot!

Edit: But yes, 25% (one full core) cpu usage o_O That's intense

Nice graph The new version seems to have more stable hashrate. I am working to remove some cpu load for the next build

OK!  I tried it.  See the image below:



You can see in the image that I changed the Intensity of "13" to an xIntensity of "128".  That is all that I did.

However, I still have stability problems.  I am running AMD drivers 14.6 beta for Linux x64.  The stability problems began happening as the sgminer code incremented from version 5.0 to 5.0.1 (or 5.1, in some versions?).       --scryptr

EDIT:  Apologies for straying slightly off-topic.  This began as a comparison of Cuda vs AMD.  I am suprized by the results that it led to.  Apparently, I've doubled my x11 hashing capacity in a couple of hours without spending the money for 6x GTX 970.  I will, eventually!            --scryptr

You should be able to reach 6,5 or 7 with this Wolf0 kernal. try

-gpu-powertune -20 -g 4 -w 64

I have fixed it now. 1/3 of the cpu and only 3KHASH lost (750ti), but needs some more work and getting late here.

those are nice hashes - but i am getting slightly more than that with the 5.1.0-dev sgminer ... you can download the dev version from nicehash/westhash also - or compile it yourself under x64 linux ... though i think the latest is faster again - with wolfs kernels ...

what is your commandline settings for sgminer?

sp - my cpu rates are around 99% running the latest pull version ...

it is hashing nicely ( at around 2700KH like normal ) but the cpu workload is huge ...

also - it seems the intensity level has no effect now ... whether -i 20.5 is removed from the commandline or not is irrelevant to the hashrate ...

Good News!     I look forward to compiling and running it tomorrow.

I just finished compiling and running the new build 22.  First, since about v1.5.0, there is a very steady hash rate on my rigs, where it varies within single digits.  On build 21, I was running about 18405kh/s, and 17810kh/s for x11 on my faster and slower rigs.  On build 22, my faster rig now runs at 18425kh/s and my slower rig saw a larger improvement to 17945kh/s.  This was an increase of 130kh/s for the slower rig.  My slower rig has no 6-pin connectors on the cards.

One thing I noticed was that the hash rate took a long time to build to maximum, about 100 accepts.       --scryptr

not liking the higher cpu usage on the new release

not liking the higher cpu usage on the new release

I would revert to release 21 until 23 comes out with its lower CPU usage. It's working wonderfully on my rig (changed motherboard and all of my issues went away. Could have been a riser on the 7th card or simply a driver issue I couldn't fix)

yep I reverted.  7 card rig?  nice!  I'm just running some extra 750ti's on my kids computers and trying to get some extra coin.

I'm wondering how others are doing with crashes?  I run on 2 win8 machines and a win7 machine and they all seem to crash in less than 24 hours.  Seems like I might have better luck with the win 8 machine or with the win7 and win8 machine that are only running one gpu.  The 3 gpu system I have seems to crash in less than 24 hours constantly. 

Last thing I did to try to improve was set compatibility to win8 and run in admin mode... not sure if that will help any.

Anyone else crashing consistently before 24 hours?

[HoY]

I just checked the CPU usage on this rig, 99% for ccminer.exe lol. its just a dual core intel g2 3220

on the plus side, it doesnt do anything but mine so I can deal with the extra lag when I log in to manage it

no downgrade ... just compiled from the git ...

fedora 19 x64 - 99% cpu load with approx 2700-2750KH on gigabyte 750ti cards - both powered and non-powered ( low profile ) cards ...

no crashes as yet ... been running for a most of today ... 6 card rig - 5 card rig ... with another 10 x 6card rigs over the next few weeks being setup with EXACT specs ...

a huge testbed soon enough

cpu load is the only issue at the moment it seems ...

they are nice hashrates HoY ...

overclocked? ...

#crysx

[HoY]

Yes, +180 +180 with factory overclocked MSI cards. the hashrate is usually slightly higher on 2 of those cards but when I'm connected on teamviewer to that rig they both slow down 100-200kh/s each. been pretty consistent and I haven't found a simple solution to that

nice ... so the assumption is that its a windows system then ...

if so - try the rdp connection thats built in to windows instead of teamviewer ... im a teamviewer advocate also - but in this instance - i would find a way to keep track with as little overhead as possible ...

or switch to linux ...

the only thing im missing knowledge ( and not many can answer this without actually modding the card itself ) is the method of overclocking within linux itself ...

sgminer is quite granular and can change settings via commandline ... ccminer has no such thing that i know of - apart from the intensity setting ... and that doesnt seem to be doing much at all at the moment ...

still - nice hashrates ...

I chose and stuck with teamviewer for its cross platform simplicity. That, and not having to manage all the port forwarding across the 10 rigs i have in my little farm. Teamviewer lets me connect easily from my iphone, from which I do most of my work while I am away from home. I have been considering switching to linux, however my farm is 4500km away on the other side of the country, and I already burden my brother with enough hardware troubleshooting as it is!

hence the reason to go with linux ...

the control over the system via console is unparalleled ... and im in a similar situation as you are with the systems when im not here in the office ...

a simple boot and ssh daemon activation on the main system ( or pxe boot with scripts to auto install with your settings ) or even a prebuilt mining package ( which i dont use as i want my own setup - hence why i use fedora on the miners ) and viola - done in a matter of a few minutes ... o - and its free ...

anyway - teamviewer is a great little package and if it serves you well - then all good i say ...

need to run some errands - then will be back to build another system with nvidia cards ... testing with one first though - and the latest compile of ccminer ... so see you in about two hours ...
