CCminer(SP-MOD) Modded GPU kernels.

On nicehash i see strange things - my home rig (49400 kh) rise in 7 minutes to 65 mh, 25 minutes work on that speed, then go down to 40-44 mh an work on this speed.
P.S. Algo quark.

Check the temperature of the cards with gpu-z. If they start to trottle (reach 70 degrees +) the cards will downclock and you loose performance. This happens to one of my gtx 970 cards.

Starts at 15.5MHASH and then drops to 13.8 MHASH after some minutes of mining because of trottling (quark)
The gigabyte windforce oc has bether cooling and keeps a steady 16,5 MHASH

You could try to overclock and overvolt the card then the trottleing will start on a higher temperature.

Cards temp is 72-76 degrees, but miner show proper hasrate and freq is stable from 1340 to1400 MHz.
All cards is Asus Strix.

Could bee a pool problem. (difficulty)
Any rejects?

Rejects is very rarely, one time in a day or 2 days...

I have ordered a gtx 950 and a gtx 980ti now. ROI in 1 year with the current prices

This meens that I can test and tweak my mod on almost all the available cards.

The titanx is too expensive. ROI in 2 years, and by then NVIDIA have probobly released new 16nm chips (pascal).

I ordered a 980ti gigabyte 3x oc card. It has 200Mz higher factory clock than the titanx on the gpu-core and should mine quark at around 30MHASH with my private miner.


BTC hash crashed, mining revenue has crashed..

30MHASH of quark will only give me $2.17 (0.030 *0.34 *212) a day, and less when I need to pay for the power  (250watt) The card costed $800 ROI without the powercost in 368 days.

time to get all the donations possible i think sp ...

when i get back into action - ill start the process on my end for more donations to you and the other devs ...

these days though - roi is impossible to calculate on any short or long term situation due to the horrid fluctuations in price ... so roi right now is not the same roi in 7 hours time ...

in any case - if the private miner can do those sorts of figures on those higher end cards - how does the private miner do on the 750ti cards? ...

No Titan X? What is this...


BTC will be back. It always comes back. If you know the right places to look you can see where the money is being shuffled around. I'd still suggest taking a look at Ethereum if you're bored... Maybe you can poke at Genoil.

7MHASH@quark on standard clocks 750ti windows x86.

I am selling off the rest of my AMD cards now and replacing with NVIDIA. 750ti/960/970. More money in building a big farm than selling kernals.

If I optimize 1% and keep it private I gain 1 card (if I have 100 cards)
If I optimize 1% and keep it private I gain 10 cards (if I have 1000 cards)

Commit 966 is slower on home rig by 300kh (960&2x980)
Pool side is slower 10-20% (spikes to 54MH, middle speed 30-35 MH)

[pokeytex]

Hiya SP - just checking in to see if there are going to be anymore new optimizations to the spreadcoin miner?  Is another donation needed?

I think I can squeze a few percent out of it. It's been a while since I looked at it. Donations are welcome, they motivate me.

Can you test commit 965 is the performance lost here or in the 966?

Can you test commit 965 is the performance lost here or in the 966?

Perfomance lost in 955 100kh (compared with commit 933), but pool side is not bad. 966 300kh lost, pool side go down 20% stable.
PS. 40 minutes on nicehash speed stable 40-50MH (my 49200 now in miner), 200 kh lower then 955.

I wonder how gtx 950 performs? Pls share the results when u have a time.Maybe i have possiblity to buy some new cards and i'm thinking to buy some 950's.. )

Are you mixing 955 with 965?

I think I will revert the 966 commit.

Sorry, yes - my mistake. 965!

Could you test x11. I got bether results with 965 on x11.

(Reducing the instruction count but adding const memory access)

Actually, I should split all the x11 kernals from the quark kernals and tune them seperatly, because the performance is not always bether for both of them.

966 show +250kh on x11 for me. now testing 965
PS. Now on 966 quark +100 kh (49500). It`s very strange...

When you test, you should let the gpu's rest for a while. 5 mins before you start the test, and then run for 5 minutes. But small optimalizations are hard to test, so I usually just look at the instruction count. Less instructions are normally bether.
