x11 hasn't been worth mining for quite some time. I kinda doubt there will ever be a complete migration, there are a lot of mine bots (viruses) out there. When YAAMP was still up, there was something like 2200 neoscrypt CPU miners on it (which isn't profitable anymore no matter where you live). I have moved to Neoscrypt from Quark. Lower energy cost and more stable.

I would like to mine Lyra if the miner can be fixed on the 970. Same hashrate as a 750ti doesn't work.

Talking about bots, a few days ago checking how Vertcoin was doing I found out that on ipominer pool one single miner called Danila (the name has been associated with infecting PC's with cpuminer/sgminer) had around 70% (11gh/s Lyra2RE) of the TOTAL network hashrate for VTC.
And he was finding the blocks as well so no exploit.

At the same time, he also had 52% of the total Feathercoin network, 13% of the total Startcoin network and 3.5% of ZRC. That all adds up to around 21 BTC profit everyday.
The ipominer owner hid the figures for some reason . More can be read in the VTC thread.

NVIDIA has fixed the nvidia-smi.exe tool in the latest driver update. (driver 6/22/2015 version: 353.30)


Here is my voltage usage and hashrate on the 53+ version (github) mining quark on one of my testrigs.

The 970 is a gigabyte windforce OC card.
the 3 750ti's are all gigabyte windforce OC cards as well (with 6 pins adapter)

Mining at default intensities and clocks (24 hours and counting in minercontrol)


750ti (p0 mode) 5700KHASH/s @ 38W  (150KHASH per watt)
970 (p2 mode)  15500KHASH/s @ 157W (98,7KHASH per watt)

It's awesome but far from perfect.

I don't trust software reported power consumption figures (with good reason) so I looked into it.
My same 970 jumps from between 130W and 205W in nvidia-smi (180W at the wall) on stock even in benchmark mode doing quark and for 750 Ti's it shows incorrect max (cap) figures.
It shows 46, 38, 45 watt figures for stock Gigabyte, Asus, MSI cards while each rig consumes about 405 watts, 70 watt being the idle power consumption of the rig so it comes down to 55.8W per card without the rig (for quark).

Here's an unmodified BIOS just pulled from an Asus card (GTX750TI-PH-2GD5):


It suggests that the nvidia-smi figures are based on the 38.5 value while that's not how much these cards can pull.
Mining groestl the rig consumes 457 watts which comes down to 64.5W per card but nvidia-smi figures are based off of the 38.5W number and it throws the card reported TDP% number (~95%) at it so it shows 37/38W and 38/38W.

With that said, my numbers are with measured numbers from the wall are:
750 Ti 5630 kh/s - 55.8W - 100.8 kh/w;
970 15300 kh/s - 180W - 85 kh/w.

Evening all - I am trying to mine Whirlpoolx.  However I keep crashing.  my settings are (-a whirlpoolx -o pool -u name -p x)  Do I have the configuration wrong?  Please advise.  Thank you -pokeytex

I don't think I ever used your ccminer, I mostly remember you coming in and criticizing existing code in the main CCminer thread, but you proved do a really great and dedicated work.

I'll probably never use your miner either but as a token of respect I donated a beer or two: f459751e1f9621ffb17f7ac35847e8e02ef4e8dfba60e57032f0999316f7b674

Thanks

sp_, what was wrong with nvidia-smi before the fix?  It seems to work great on my Linux install, there's just no power readings.

Thanks alot. I found some things that could improved, and used some months to do improve it. All the hashing algorithms have been optimized. Some a few percent, others up to 100%. I started 10-11 months ago. But I have got help from the other ccminer developers as well. Epsylon3, schleiser and djm34

Can you change the clocks? with the -ac parameter?

Evening all - I am trying to mine Whirlpoolx.  However I keep crashing.  my settings are (-a whirlpoolx -o pool -u name -p x)  Do I have the configuration wrong?  Please advise.  Thank you -pokeytex  

What card are you running? You can try to lower the intensity -i 22 if you are on a 1 gb card.

-ac (application clocks) just set the max clock for the app, its not overclocking except if the card allow it. but the increase is due to the enabled P0 State (on the 9xx). It happens when you set the highest memory clock supported (4 memory clocks are possible)... EDIT: in fact its seems to set the P0 whatever the values we use...

For linux, to get the power readings, you need the 352.21 driver (was just implemented) or 353.30 on Windows

And there is another new feature i just implemented... the Power Limit --plimit=190W

PS: tx to send the fees to the right person about that

I have (3) 970's 4gb (1) 960 2gb and (5) 750ti's 2 gb.  I am not using an intensity flag.

maybe you should use the -i intensity parameter as sp suggests ... to lower the default intensity ...

are all the cards in one machine? ...

I think the x11 can be improved on NVIDIA by rewriting the tablebased AES algorithms.
Quark is 9 chained scientific hashingfunctions with branching and does 6MHASH (750ti)
x11 is 11 chained scientific hashingfunctions and does 3MHASH (750ti) (with table bases AES echo and shavite)

A rewrite of the slow echo and shavite is needed..

I think that 4-5MHASH is possible on the 750ti

that would be something to see ...

it one of the main algos we mine with ...

but then - we have always pushed for more x11 optimizations ...

Whirl is broken for me too. Reducing intensity doesn't do anything.

Whirl works for me on headless rigs, but not on rig with monitor.  Maybe something to try.

I am still on 346 Linux drivers and I set my clock and mem speeds in .nvidia-settings.rc as an attribute.  My xorg.conf file enables all gpus in the system as well as coolbits.

Agh, Yaamp was gobbled up by Nicehash. It was one of the few alternatives to that lumbering behemoth. Does anyone have a site as good as yaamp that's not nicehash?

Also is it even possible to fix lyra2 on the 970/980? Someone said the memory controller is getting maxed out, in which case this is a hardware limitation and lyra2 will always be gimped on the 970/980?

Weren't yaamp's fees substantially higher than nicehash's?

And yaamp's payrates, even before the fees were removed, were lower than nicehash?

I am not one who is happy to see yaamp gone, but I don't understand why you preferred it.

Enlighten me.

Djm34 has recoded lyra and it does 2.8 mhash on the 780ti, and a big less on the 980.

current pool stats
r7 240 @ 266k   gtx 750ti 475k  cpu 419
the nvidia is using ccminer with open cl
I've seen the nvidia in the 700k once. cpu seems to always be the fastest
between all 3 I've been as high as 1.2Mhs. that was before I started tweeking the R7.  the 750ti is running @ stock.

ccminer with opencl   (yeah why not...)
current speed on an unreleased ccminer lyra version:
750ti: 1140kh/s
780ti: 2800kh/s
980  : 2400kh/s
