CCminer(SP-MOD) Modded GPU kernels.

[chrysophylax]

agreed on many points ...
there would be many many reasons why ccminer devs would not want to work on sgminer code ...
even wolf - who is a long time dev of opencl AND sgminer - has a great deal to say about sgminer's internal workings ... but all those stats at a glance - stats-candy ...
ive been watching multiminer for a very long time - even tried getting it running under fedora 20 x64 with no success ... havent toyed with it for a while now - too much on my plate ... but would definitely be worth a look-in to see whats happened with it ...
only a small part of the farm is amd - gigabyte 7970 oc and 280x oc ... about 22 cards left i think from memory ... wasa great deal more than that until nvidia kicked serious butt with hashrate and power consumption ... which is why most of the farm is now nvidia ... but i do have a soft spot for amd still - which is why these cards are still running ...
so i guess its a matter of workign what you have ( and forking your own builds ) or building from scratch and developing a 'new' miner ...
cant wait for that to happen ...

I have done very little for AMD, but the small changes I did was directly in the .cl code of the kernals.. I plan to do some more later as I have quite a few cards I picked up cheap.
Kachur bins does 13MHASH on quark on the 280x and 7.5MHASH x11. I use miner control software to avoid crashes and lost mining..

so does this mean you will be spending more time on opencl optimizations? ...

these are the two main algos i am much more interested in also - so the higher the optimizations - the better ...

I'm working on neoscrypt speedup, currently around 5% hashrate increase.
Beers appreciated ;-)

Yay...

that's what you need to beat: 850kh/s on 980 200kh/s (but if I have a bad 750ti) and 500kh/s on 780ti

ps: on a bitter sweet note, usually when I submit updates, I usually don't get beers, just devs outsourcing my stuff and eventually getting beers

I do not have any of those cards, just a 970; what's your hashrate on that card?
about beers, I got none of them: got BTCs only when selling.

yeah me too... (hopefully)
don't have a 970, but it should scale according the perf of the 980 (considering it is the same mem bandwidth)

Anyone upgraded to windows10 ?
can you share your impression especially on the 900 serie.

So far I tested (and went back to win8.1) on 780ti, 750ti and 980
perf of the 750ti and 780ti didn't change much, but for the 980 got huge loss of performance (like 20% on neoscrypt and similar on cryptonight)

Was beta testing but here is what I am curious about since the new driver for DX12 is out.

In the past if you SLI'd say 2 960 4Gb then Windows would only read them as a total of 4GB but now Windows 10 will recognize them as 8GB total memory. It has to be implemented on the developer end though to take effect. Would this help in the few memory heavy algos if ccminer could implement it?

not sure it would help, unless you mine only with one card and even then, the performance in accessing the memory from the other card would be terrible...
did you try mining with your cards ? did you noticed any difference ?

No difference at all. Slight (very) gain with some algos and slight loss on others. I don't have a 980 though it was with 960 and 750ti's.

At the time Windows 10 was having wifi issues so I would only test it on Sundays and the driver for DX12 was not out yet so they all where still buggy drivers.

Will run this Sunday since it is my first day off to be home with the release.

could be only the 980 (heard that the 980ti wasn't even recognized...). I think epsylon didn't notice notice any problem either...
could also be the sli bridge (the sli wasn't activated, but the bridge is always in place... and it was less trouble to downgrade than opening the tower... so...) well I guess I will make another try when nvidia release a new driver...

Maybe if you poopoo'd less and got drunk more, you'd get more beers.

Doesn't change anything. If there is a performance difference there, it needs to be unlocked. At least it doesn't hurt hashrates. W8.1 x64 to W10 x64.

I have a 970 and mining Neo. If anything it looks like it minimized GPU utilization spikes. Almost all my GPUs across the board have no fluctuation what so ever. The overall hashrate hasn't really changed though. GPU usage and Power is just flat.

I also have problems remoting into the W10 PC. I may revert it.


BTW looks like Bytecoin is almost worth mining, if only Cryptonote performed better.

Does anyone happen to know the current speed for Neo-scrypt on a 750ti, 960, and 970?

GTX HASH RATES--

I get 180kh/s, 320kh/s, and 510kh/s, respectively, for NeoScrypt.  I do not have a GTX 980.       --scryptr

I get around 650kH/s for NeoScrypt on GTX980.  But that's with TDP limited to 150W.  I figure out it's more efficient to run at lower wattage.

No, sorry, the hash it generates goes for bread, beer, and occasional donations.  Yours took 7 days to confirm last time;  blockchain traffic issues.  Pallas might be in line for one if the Axiom algo gets hammered out between the movers and shakers in the Cuda world...      I wish I could code better.       --scryptr

This speed look about normal for a GTX960SSC under these conditions ?
Command line as followed: ccminer.exe -a Quark -o stratum+tcp://quark.ua.nicehash.com:3345 -i 22 -u zxxxxz -p x -d 0 -l 16x24
I set -i to 22 to make the system more use friendly, default was causing a bit of lag while doing other things, like surfing or open GPUZ tabs.

-l 16x24 shouldn't be necessary? thought that was just for scrypt based algos

[zTheWolfz]

Its probably not, I had just gotten use to adding it so it didn't run the 2min. benchmark each time it was started.
I've removed it to see if there will be any improvement without it. So far looks about the same, starts out with a little higher
khash rate but settles in after its been running a good long while to what you see above, will see if that is the same now without it.
I worked with it a good while last night and at first was getting some booo's as you can see that has been corrected by the accepted counts.

Edit: These are the numbers I am seeing without it but was also seeing these same numbers last night/early morning.
The above number could have been changed by the heat of the day and didn't think to look at the clock speeds to
see if maybe it had down clocked a little and didn't ramp back up after it cooled back down.

Note that for some reason the memory clock is not being pushed to its full speed. Should be 1753Mhz, but the core clock is at
1392Mhz and stock clock for core is 1279Mhz for this card. Boost at work there but not for the memory?
