CCminer(SP-MOD) Modded GPU kernels.

[serg_25]

SP_  (and all ccminer devs) you made really great job.  lyra2v2 hashing extremely fast on such small cards.
after couple hours of playing with configs  i could reach:

Code:

[2015-09-17 17:38:00] GPU #0: GeForce GTX 750 Ti, 5025 Temp= 50C Fan= 41%

crazy speed.

Do you mind to share your config?

everything is by default.
./ccminer -a lyra2v2 -o stratum+tcp:// -u  -p -X 5


only overclocking. my card was mining on 1500 but after 5 mins i had a driver crash. on 1490 it's stable.
but i didn't play with Memory Transfer Rate. According to your messages with memory adjustments card won't mine faster, just less power consumption?

Try release 68, it should be faster on the 750ti. I use -X 10 as the default value. (Experimental intensity) 37,5% less gpu memory needed.

I get 5MHASH on 1388Mhz core and 2700 MEM. (750ti 38W tdp)
The 970 is peaking at 9950KHASH

Agree, Ethminer is still very lucrative although it looks like Nvidia hardware hit the memory controller limitation and can't go anywhere else, much like Cryptonote.

Look at lyra2v2. It's also a memory hard algorithm.

280x Sgminer opensource(200watt) 4MHASH
750ti Djm-34 (sp-mod) opensource (40watt) 5MHASH

It's like creating a etherum miner that does 35MHASH on the 750ti.

But the opensource is only doing 8MHASH...

Small donation SP_ after 15h mining in "fun mode"

72d7954e6d2086526ebb674ed5a789154beeac31e19b1e0430664575fa8fa96f

yep not much but better than nothing

P.S. already checked 1.5.68 release. yep a little bit faster on 750Ti.
in nearest two days will check power consumption on different core and memory, will post results.

[sp_]

1.5.68(sp-MOD) is available here: (17-sep-2015)
Post your stats here. Card name/gpu clock/memclock

Geforce 840M (1200 gpu/1100 gddr3) quark: 3500kh/s, t=62C

he-he. The maxwell junior on the Laptop!!!

Hashing quark faster than sgminer on the 290x with the opensource kernal.

Thanks. In 10 years they might be worth 1000$ a piece. :-)

If you have time, Run the miner with different x settings and check the power usage / hashrate.

-X 1
-X 2
-X 3
-X 4

just tested with 1388 core, but couldn't set 2700 mem, the lowerest what i can do - 5400(stock) - 2100= 3300 mem. everything which is lower - driver crash. seems like it depends on card.

but with 1388/3300 can reach only
GPU #0: GeForce GTX 750 Ti, 4555 Temp= 50C Fan= 39%



but still without power consumption info.

[sp_]

Depends on your software but I think the mem is multiplied by 2. so 2700 in one software is 5400 in another.

I get 5MHASH with 1388/5400 (x86 windows)

bensam1231 , I don't have watt meter . I think it's a consumption of 120 watts . Voltage standard 1.193 .Don't increase the voltage . Just increase the TDP BIOS . See the screenshot ..

Hmmm... Every miner should have a watt meter. Buy one for $18 on Newegg (Don't get a Kill-A-Watt, they break like clockwork every month).

Voltage doesn't tell a whole lot or TDP as Manufacturers change it around.

I lost about 20 btc on an exchange that got "hacked", although I think they just took it all and ran. When it was up to about 1100$ a while ago.

I got mad and quit mining altogether, I just now got back in the game and this quark mining power on nvidia cards is insane. When I stopped mining it was still cpu only.

I get about 54mh/s with 2 980ti's mining quark, slightly overclocked and -C and -i 25.

Any one get any better results? I think this is a great number but I want the most I can possibly get, just like the rest of us.

Donation coming soon once I build up a little more coinage.

 

Hashrate doesn't matter. There isn't a linear increase between profits and hashrate as coins are smart and auto adjust to the network. Only way to get ahead of the curve is with better hardware (ASICs) or custom kernels. Both of which don't do anything when everyone is using them.

You very well could've been making more money back when Quark was CPU only, although it seems like CPU only coins always end up fodder for botnets.

I understand the that the network adjusts to the hashrate, I only meant to point out that technology is a fast moving m f'r. And I love it.

Hashing quark faster than sgminer on the 290x with the opensource kernal.

I updated my post a bit ))
quark made it to decrease gpu clock (PerfCap Reason: Pwr), but with neo and lyra there is a space left for o/c

Upd: I decided to let it throttle if it wants to and push it to the limit (1260/1180) and got 3650kh/s in quark)))

on our gigabyte 750ti oc lp cards -i 22.9 seems to be the best intensity and the best hashrate so far for quark ...

though thefarm is now back on x11 ...

The main difference between the algo of ethereum and other mem hard algo, is that you can't rescale mem usage as it always requires the full dag file to run (ie 1.2Gb or so of vram with many random over the full dag file)
Meaning you can't really improve passed what has already been done... (yeah, I tried already  ).

But you should be able to make the kernal run at copyspeed. (memory bandwidth limit) The gpu can do register operations while writing to memory. The keccak passes should be integrated and more than one hash per run. Then you will get keccak for free. (memory pipelining)

Not sure what you mean about a 35MH/s Ethereum miner. Cudaminer Ethereum is currently more profitable then the pub Lyra miners. 20% more and it would be more profitable then Ethereum, but still not as profitable as Quark right now (that includes power usage).

Looking at GPUZ Lyra doesn't peg the memory controller at 100% like Cryptonote and Ethereum does. It sits at about 50%

Also I don't know why, but I just checked L2v2 on .68 and it's missing about 1MH/s compared to the DJM version.

T-nelson was working on it when a "Lyra2v2 doesn't work" false alarm propagated thru the thread.  He is diagnosing with one 750ti, so it may take a week to hit a block and get error log and debug info.  CryptoMining Blog states that CCminer crashes on hitting a block, and my personal results agree.  However, I was not running any error-catching software.       --scryptr

Thanks. i got one crash when found a block so that block has not been accepted. Waiting for the fix.
