Release 56 has finally made be break 100 mh/s on quark. Virtual beers for everyone!

Aliman,
Your 980ti is beating the Titan-X

The titans in this picture are to close to eachother. They will heat up and trottle.
Bether to use 70cm usb risers and spread the cards.
The titans are not good for mining. 12GB of ram doesn't help, and the prise is skyhigh.

Wrong about the heat; servers tend to be cooled differently. Right about everything else.

Cooled differently by magic I presume?

Forced cool air in the front and out the back.

And those are the characteristics of the blower type heatsink, it's got nothing to do with being a server. Right now, it's actually like a test bench. And SP is right about the risers and all.

I meant, rack mounted systems tend to have cold air forced in the front - you could actually have them not overheat.

But unfortunately, they still do over heat. One card absorbs the heat of the other, and it moves all the way to the last card.

How's the power consumption on 980ti , compared to 970 ?

Lets see, this does 268 - 280W at the max, running at 1500Mhz. My MSI GTX 970 4G consumed something like 220W, given the custom PCB and heftier power connectors.

From my side +50-65 k/hash for 750Ti's and 200k/hash for 970 with built 56. Good work sp... )))

More is coming... If you want a higher hashrate, Please donate some beers.

7.05 MHASH per 750ti.

With djm34's changes we perhaps get 7,5MHASH per 750ti ??

Hm, cuda porn!!! Grin

The TitanX's should be awesome for high n-factor scrypt-n and scrypt-jane. The 12GB of VRAM will be entirely useful in Linux, and the cards will run much cooler with a properly selected lookup gap, trading a little bit of hashpower, for a lot of thermal and power savings. For every other algorithm, meh, waste of money Cheesy

Glad to do it. Please point me to the piece of code that does the check and I can look into it.
Some more info: ubuntu 15.04, network card and link are up but the connection to the gateway is down.
From the power meter I can see a slight reduction in power usage but the output, while including the connection issues, it also includes the normal hashing of the cards.

take a look at this commit:

From the tpruvot branch: prevent gpu scans before a job is recieved:

https://github.com/sp-hash/ccminer/commit/8f7f6dfd8f627fefd2f5a2fbda4612827588ef02

This will prevent the miner to start if no connection is there in the startup. But if the connection has timed out, there is no code that stops the gpu to mine

maybe we could set a global flag when, say, 3 shares submission fails, then add that flag to the check you outlined.

actually it is a behavior which appeared "recently", the first versions of ccminer didn't behave like that (and yes it is boring...)

I prefer to spend time on faster kernals. If you can do fork my fork and make a pullrequest when you are done, I will add it.

yes, sounds good. We also need a failover function if one gpu is failing. Now ccminer will just exit if one of the gpu's in the rigs are failing. one flag per gpu, and a sleep and restart method.

Do you want me to try doing that flag thing or are you going to do it yourself?
I'd do it right now but I can't test network downtime 'cause I'm remotely connected to the rig ;-)

@sp_ , how does the c11 algo compare with quark algo power-wise? safe to keep the 750ti overclocked ~ +100 MHz?

c11 should be equal to x11 power-wise
