Probably a driver issue or maybe it has something in common with coolbits 28...

The cryptomining blog has compared release 74 with release 78 on a gtx 970 card x86 build(compute 5.2):

blakecoin +8%
lyra2 +6%
quark +3.8%
lyra2v2 +1.3%
x11 +0.2%

I have done alot of work to reach these speeds with cuda 7.5 ( 41 commits):

https://github.com/sp-hash/ccminer/commits/windows

But I am not done...

x13, x15, qubit and neoscrypt are still behind.

On AMD you probobly undervolted your cards to get them to use less power. On Nvidia you change the TDP of the card. You can do it in software with the nvidia-smi tool, or modify the bios. (voids warranty)

yes I modded the bios myself, 0.8V, stable at 860Mhz, 1250 mem (sapphire 7950 dual X oc)
are you saying that i can run under linux, before loading ccminer, a nvidia-smi sentence that will change in real time the TDP of every card??? WOW!!! I thought that the only way was modifying the BIOS!, do you have any link / tuto or hint how to?, I will get right on it!.

To modify your bios to change the TDP you can follow these steps:

http://cryptomining-blog.com/1014-how-to-increase-the-geforce-gtx-750-ti-power-target-limit/

But a software solution is bether. Upgrade to the latest drivers.

It works on Linux. You might also want to set persistence mode: nvidia-smi -pm 1 -i 0

hi all ...

can anyone help with this issue i have with the current build ...

im stumped as to why the 6th card on the new 'big' build of 980ti g1 and 980ti extreme refuses to work with the latest drivers ...

remove just ONE card from the lot - and it will run and mine ... and mine like a bat out of hell at that ...

the setup is exactly the same as the 750ti oc lp card setup - but these cards refuse to work with more than 5 cards ...

has anyone had an issue like this before? ... would it be an issue with onboard ram? ...

the system has 16gb high performance ram - h81probtc - g1840gpu - kingston v300 120gb sdd - 2 x corsair ax1200 psu ( 3 cards per psu - with the first psu running the power to the motherboard and ssd ) - usb3 risers ( all powered ) along with the 2 x 4pin molex power connectors ( as redundancy ) via the motherboard - 4 x gigabyte 980ti g1 cards + 2 x gigabyte 980ti extreme cards ( higher clocked ) for a total of 6 cards ...

when 5 cards of ANY combination are running - all is ok ... when the 6th card is installed - the boot refuses to load nvidia drivers ... the version of drivers plays no part in this as the drivers have been tested with different versions and they ALL do the same thing ...

fedora 23 x64 cuda 7.5 ( f23x64c75 ) and ccminer-spmod78 ...

the elusive 6th card is the only thing holding this monster of a miner back ... and is holding back the installation into its custom aluminium frame ...

any ideas? ... anyone? ..

the 6 x 750ti oc lp cards work in a factor of 6 - but they are installed ( with similar specs - apart from the psu ) as another miner ...

so in effect - no i havent tried them in THIS machine ... so that should really be the next step ...

the machine has 16gb high performance ram ( 2 x 8gb kingston hyperx 1600 ) - so it 'shouldnt' be the ram causing this ... but i have never built a machine this large as a miner ( just because i have never had the cash to - my mate does ) so anything could be the go with this ...

why do you think it could be lack of internal ram? ... i cant remember whether these boards support 4 x dimm slots on board ( as im not in the office until tomorrow afternoon ) ...

if so - ill buy another set of the 16gb kingston hyperx fury ram and see how it goes tomorrow ...

but let me tell you sp - just in the benchmark modes - these things are a hashers delight ... the extreme version is one hell of a hasher and is only $30AUD more than the g1 ... all stock - no oc ...

if its not the ram - then im STILL completely stumped ...

its not the connections ... as no matter which card you disconnect - it ALWAYS works when there is 5cards attached - and NEVER loads the nvidia driver when there is 6cards attached - no matter which combination of cards are plugged in to the pcie connectors ...

Weird. I'd try only using 1 stick of ram (or disable dual channel), using one card as main and disable onboard graphics, try different BIOS settings (pcie link speed) and of course disable render standby, try different risers, drivers, etc.
Also, disable USB3, only use 1 sata device (in case you ran out of PCIE lanes).

@chrysophylax
6x 980ti is not very common
My experience with h81pro btc + 8GB + G1820 is running incredibly troublefree from the beginning. I couldn't be happier. Both lubuntu(usb stick) and windows 7(sata SSD) runs perfectly without any issue. Even installing Win with all gpus allready plugged and using wifi usb dongle all the time.
The biggest difference from Your build is 980+3x970+960+750ti and all running from the same psu(LEPA G1600).
I have never plugged the molex connectors to the motherboard. It is meant to power the old(shitty) unpowered pcie risers.
I have forgot the exact bios settings, I think I set the pcie to gen1 instead of gen2 or 3 and switched off the integrated cpu graphics for sure.

We might have a different bios version on the mobo or it might be just 980ti using more resources.

On my other desktop motherboard(much more expensive one) I got many problems allready with 3 or 4 gpu's. I had to plug one by one and sometimes it didn't work until I changed the pcie riser... Very strange behavior.
 
Good luck 

BTW I prefer Win7 x64 by far for mining.
