My new gigabyte windforce 980ti is hasing quark at 26.1 MHASH with the opensource (release 61 +) on factory clocks. x11 is at 12.7MHASH. Seems to draw around 250w. But I need to do a wall reading.

9800 GTX+
My 9800 GTX+ did 14kh/s on scrypt with CudaMiner when I tested it.  Makes me wonder when we'll have 950ti cards, and whether the next generation of cards will have 16nm chips or use layered technology.  What is next?
--scryptr

The AMD 7970 is 3 years old and still hashing pretty good. I think the maxwell series will last for at least 2-3years as well. In the gpu race we have seen the the last years, new hardware is comming out so fast that the coders don't have time to find out how to optimize it...

Anyway I filed a bugreport on the drop in the hashrate on cuda 7.5. x11 is doing 1.9 MHASH in the 750ti. All AES algos are spilling registers to memory like a virgin in a brottel.

Solomine is broken. PLZ look on this...

[sp_]

Solomining has been fixed.

you can download the latest bin here(or build from github yourself):

JSON-RPS CALL FaILED... and debug... dont work. recompile and test. Download and test. QUARK.

[sp_]

Use this fork. It has incredible API with a remote control feature and a faster hashrate

 Why is the quark algorithm varies the voltage and frequency ? release61
Pull shows 6 MH - 9.03 MH ,miner 10.4 MH.

It is not quark it is Your graphic card throttling. Probably TDP throttling, try increasing TDP limit.

Thanks for the reply . Need to edit the BIOS increase TDP. 'll think .

Isn't there any headroom with the power target slider on Your(shitty ) picture?

I managed to get the 980ti up to 13MHASH(+250khash) now in x11. Quark is up to 26.6 MHASH(+500KHASH)
blake512 rewrite. Reduced the codesize and registercount. Vector writes to memory...

Submitted on github.

All compute 5.2 devices get a visible boost.

970 +300khash quark..

building release 62...

[sp_]

-Faster x11,x13,x15,nist5,quark on compute 5.2 devices. (quark on the 980ti +500KHASH)
-Faster lyra2v2

1.5.62(sp-MOD) is available here: (29-08-2015)

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

The sourcecode is available here:

My EVGA superclocked gtx 950 mines quark at 8.3MHASH on factory clocks. Release 62

I have the same card. How far does your boost by default?

Mine goes to 1380. I got shit ASIC, only 66%

Good job
What is the actual core clock of your 980ti?
Check your PM btw.

[sp_]

980ti :

The core is at 1278MHZ mem at 1652MHZ

+150mhz on the card is possible and the hashrate goes up to 29-30MHASH

But the 750ti is still the best for hash/watt.

100% more power on the gtx 950 and just 40% higher hashrate (quark)

Becareful with Gigabyte. I just got some Gaming G1 970s in that are overclocked quite a bit, but they offset that with a crapton of voltage... and they STILL end up locking up around 1500~ core if you try pushing them.  They gobble 220w a piece on Quark... I'm actually debating on sending them back right now, but restocking fees are killer.

[sp_]

I think I will not overclock my gigabyte cards, they are running pretty fast already, but you are right about the power draw..220w on the 970 is extreme when the 980ti is only pulling 250-300w

Edit:x11 r61 better than r57 Seeing mixed results depending on algo mined.  

Can you please test r62?
Is it bether than r57 on quark?

x11 on  750Ti -200kh. On quark whithout changes..
