CCminer(SP-MOD) Modded GPU kernels.

With a hashrate of 6.250 KHASH. (around 25 750ti's)

you get around 6.66 XMR per day with the current difficult and miner.

That's 0.00986 btc/day.

You'd need $0.065/kwh electricity just to break even.

A 750 Ti should do around 498 hashes/s just to be on par with x11. That is if we only look at immediate profit and exclude speculative mining.

But the code is shit. It's written for the cpu and not the GPU. AES in slow motion

edit: but the cpu botnet code is really good. Almost 3lit3

so a rewrite wouldnt do it justice? ...

although it would probably mean a hell of a lot of work to rewrite the code for gpu and make it work well ...

well - i think we will just have to see ...

Cryptonight sp-mod version 1 exe file has been sendt to the donators. My first afternoon of work gave an increase of around 10% on the 750ti.
This will increase in the next releases.
If you want to join the train please donate 0.2 BTC and recieve both the optimized Spreadminer (with source) and the Cryptonight mod.
my BTC adress is in my signature.

Do you have an estimate on how much extra hash can you squeeze out of your cryptonight miner?
On a sidenote, your spreadminer v7 has the lowest fluctuation I've ever seen in any algo. It only fluctuates 1-3 kh/s.

I think 30-100% faster is possible but it will take alot of work. I have started with the easy pickings.

Big numbers. I know the code is shit but what exactly did you plan on doing to get those improvements? Perfectly optimizing (to zero runtime, not possible but for the sake of argument) everything but the core phase 2 gives you 21% which would be nice of course. Then you have a loop with 262144 iterations, each of which does something like 8 16-byte reads/writes to pseudo-random locations in the 2MB scratchpad. No way to get coalesced memory access and the GPU can't do shit to hide the memory latencies because you're running a really really small work, due to being limited by the 2MB / thread scratchpad requirement.

does ANYONE know how to oc under linux? ... anyone at all? ...

"Coolbits" "#" needs to be set within the device section of the xorg.conf, then the PowerMizer setting becomes available in the NVIDIA X Server Settings.

"The Coolbits value is the sum of its component bits in the binary numeral system. The component bits are:
1 (bit 0) - Enables overclocking of older (pre-Fermi) cores on the Clock Frequencies page in nvidia-settings.
2 (bit 1) - When this bit is set, the driver will "attempt to initialize SLI when using GPUs with different amounts of video memory".
4 (bit 2) - Enables manual configuration of GPU fan speed on the Thermal Monitor page in nvidia-settings.
8 (bit 3) - Enables overclocking of Fermi and newer cores on the PowerMizer page in nvidia-settings. Available since version 337.12.[1]
16 (bit 4) - Enables overvoltage of Fermi and newer cores using nvidia-settings CLI options. Available since version 346.16.[2]
To enable multiple features, add the Coolbits values together. For example, to enable overclocking and overvoltage of Fermi cores, set Option "Coolbits" "24"."

It would look something like this:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "Coolbits" "8"
EndSection

but it does only work with the 750ti - i had no luck with the 980's so far

[sp_]

This is cryptonight sp-mod 1 in action with stable overclock(windows 7):



Without overclocking the 970 does 452H/s

The launch config on the 960 is way off, so I need to find the right config.

[sp_]

I submitted a 5MHASH increase in Keccak (750ti)

My testrig. 750ti,960 and 970 are doing 830MHASH together.

Keccak is more profitable than x15 now at Nicehash, but still abit below the other algos.

what is the miner to mine cryptonight with gtx 970 ??

[sp_]

I am working. Search for Claymore. H7s miner is realy good

[ol92]

I am working. Search for Claymore. H7s miner is realy good

I believe his miner works only with amd cards.
He has a good cpu miner too.

[chrysophylax]

I am working. Search for Claymore. H7s miner is realy good

linux miner for us donors that NEED it on our machines please ...

just sayin ...

Today I have added whirlpoolx. I will not submit the kernal to github beacuse its too fast.

the 970 does 425MHASH on standard clocks. How fast is the 5% DJM version?

The fastest released miner on the 970 is doing 195 Mh/s that I have seen.

Mine is doing
495MHASH on the 980
425MHASH on the 970.
250MHASH on the 960¨

Testing it on the pool now.

edit: the pool is showing lower numbers. Need some more work.

I think you might be on par with Wolf0.

I get some hardware errors. around 7% of the yays does not validate on the cpu. The kernal need some more work.

[sp_]

Sorry guys, the kernal was broken. The real hashrate is around 200MHASH on the 970.

Djm version on a OC on a gtx980 miner reports 200 mh but pool side only reports 80-100

[djm34]

Djm version on a OC on a gtx980 miner reports 200 mh but pool side only reports 80-100

depends of the pool and of the difficulty setting... (I did test it on both suprnova and nonce-pool and the hashrate was rather consistent)
